Can someone please help me understand how to answer for x, y? Thank you so much!
Answers
Answer:
X = 45°
Y = 72°
Step-by-step explanation:
There is a supplementary angle (an pair of angles that create a straight line is equal to 180°) and there is the rule that all three angles in a triangle equal 180° as well.
Answer:
x = 45° , y = 72°
Step-by-step explanation:
A straight, horizontal line is equal to 180°
x = 180° - 135°
x = 45°
We can find y because we know that all three angles of a triangle equal 180°
So what do we have?
63°, 45°, y
We can make an equation:
180° - (63°+45°) = y
180°- 108° = 72°
y = 72°

as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.
\(\stackrel{f(x)}{y}~~ = ~~2x^2+4x\hspace{5em}\stackrel{\textit{quick switcheroo}}{x~~ = ~~2y^2+4y} \\\\\\ x=2(y^2+2y)\implies \cfrac{x}{2}=y^2+2y\impliedby \begin{array}{llll} \textit{now let's complete the square}\\ \textit{to make it a perfect square trinomial}\\ \textit{by using our good friend, Mr "0"} \end{array} \\\\\\ \cfrac{x}{2}=y^2+2y(+1^2-1^2)\implies \cfrac{x}{2}=y^2+2y+1-1\implies \cfrac{x}{2}=(y^2+2y+1)-1\)
\(\cfrac{x}{2}+1=(y^2+2y+1^2)\implies \cfrac{x}{2}+1=(y+1)^2\implies \sqrt{\cfrac{x}{2}+1}=y+1 \\\\\\ \sqrt{\cfrac{x+2}{2}}=y+1\implies \sqrt{\cfrac{x+2}{2}}-1=y~~ = ~~f^{-1}(x)\)

i need answers to these in 10 minutes.
Answers
Answer:
a) The inverse is g(x) = (1/70)*x - 50/70
b) The slope intercept form is y = -6*x - 47
Step-by-step explanation:
a) When we have a function f(x), the inverse of this function (let's call it g(x)) is such that:
g(f(x)) = x
f(g(x)) = x
for every x.
In this case, we have:
f(x) = 70*x + 50
This is a linear function, and the inverse will be also a linear function.
Then the inverse will be something like:
g(x) = a*x + b
then:
g( f(x)) = x = a*( 70*x + 50) + b
then we can just solve the equation:
x = a*( 70*x + 50) + b
x = a*70*x + a*50 + b
If we separate terms by the powers of x in each side of the equation, we have:
1*x + 0*x^0 = (a*70)*x + (a*50 + b)*x^0
(where x^0 = 1)
then:
1 = (a*70)
a = 1/70
and:
0 = (a*50 + b)
0 = 50/70 + b
-50/70 = b
Then the inverse of f(x) is:
g(x) = (1/70)*x - 50/70.
b) The slop-intercept form of a linear equation is:
y = a*x + b
where a is the slope, and b is the y-intercept.
We want to write in this form the equation:
y + 5 = -6*(x + 7)
The first step is to isolate the "y" in one side of the equation:
y = -6*(x + 7) - 5
Now let's simplify the right side:
y = -6*x - 6*7 - 5
y = -6*x - 42 - 5
y = -6*x - 47
This is the slope-intercept form, where the slope is -6, and the y-intercept is -42.

Part a: For ΔABC - scale factor = 2Part b: For ΔDEF - scale factor = 1/2Part c: For ΔGHJ - scale factor = 1/3Part d: For ΔKML - scale factor = 3Explain about the dilation:A transformation that changes the size of a figure is called a dilatation. This indicates that the preimage as well as image are similar and have been scaled up or down, respectively.
A dilatation that results in a reduction (imagine shrinking) or an enlargement (think stretching) produces a smaller or larger image, respectively.
Part a: For ΔABC
Length AB = 2 units
Length A'B' = 4 units
A'B' = 2 *AB
Thus, For ΔABC - scale factor = 2
Part b: For ΔDEF -
Length DF = 2 units
Length D'F' = 1 units
D'F' = 1/2 DF
Thus, For ΔDEF - scale factor = 1/2
Part c: For ΔGHJ -
Length GH = 3 units
Length G'H' = 1 units
G'H' = 1/3 GH
Thus, For ΔGHJ - scale factor = 1/3
Part d: For ΔKML -
Length KM = 2 units
Length K'M' = 6 units
K'M' = 3*KM
Thus, For ΔKML - scale factor = 3

The vertices of triangle CDE are C(-3, 3), D(4,9), and E(6, 1). Translate triangle CDE using vector (5. - 3).
Answers
The triangle CDE with vertices C(-3, 3), D(4, 9), and E(6, 1) is translated using the vector (5, -3). The translated triangle C'D'E' has new vertices C'(2, 0), D'(9, 6), and E'(11, -2).
To translate the triangle CDE using the vector (5, -3), we add the components of the vector to the corresponding coordinates of each vertex. The x-coordinate of each vertex is increased by 5 units, and the y-coordinate is decreased by 3 units.
For vertex C(-3, 3), adding the vector (5, -3) gives us the new coordinates C'(2, 0).
For vertex D(4, 9), adding the vector (5, -3) gives us the new coordinates D'(9, 6).
For vertex E(6, 1), adding the vector (5, -3) gives us the new coordinates E'(11, -2).
Therefore, the translated triangle C'D'E' has vertices C'(2, 0), D'(9, 6), and E'(11, -2). The triangle has shifted 5 units to the right and 3 units downward.

When can parallelism make your algorithms run faster when could it make your algorithms run slower?
Answers
When an algorithm necessitates extensive sharing of instantaneous results, parallelism slows it down. Because there are multiple independent parallel processes and the right number of threads, parallelism will speed up an algorithm.
What algorithm is parallelizable?The ones with data dependencies are the most challenging. It will be exceedingly challenging, for instance, if you are dealing with a vector and the input for the computation at point n depends on the output at position n-1.
When this occurs, you must comprehend what the original algorithm is doing and take an alternative approach. For the aforementioned case, it might be a difficulty with digital signal processing including a feedback-containing digital filter. These are challenging to parallelize, but that is not the sole solution. Instead, you might use the filter and signal's fast Fourier transforms, multiply them, and then perform the inverse transform. All of these operations can be partially parallelized.

Consider the following game, where player 1 chooses a strategy U or M or D and player 2 chooses a strategy L or R. 1. Under what conditions on the parameters is U a strictly dominant strategy for player 1 ? 2. Under what conditions will R be a strictly dominant strategy for player 2 ? Under what conditions will L be a strictly dominant strategy for player 2 ? 3. Let a=2,b=3,c=4,x=5,y=5,z=2, and w=3. Does any player have a strictly dominant strategy? Does any player have a strictly dominated strategy? Solve the game by iterated deletion of strictly dominated strategies. A concept related to strictly dominant strategies is that of weakly dominant strategies. A strategy s weakly dominates another strategy t for player i if s gives a weakly higher payoff to i for every possible choice of player j, and in addition, s gives a strictly higher payoff than t for at least one choice of player j. So, one strategy weakly dominates another if it is always at least as good as the dominated strategy, and is sometimes strictly better. Note that there may be choices of j for which i is indifferent between s and t. Similarly to strict dominance, we say that a strategy is weakly dominated if we can find a strategy that weakly dominates it. A strategy is weakly dominant if it weakly dominates all other strategies. 4. In part (3), we solved the game by iterated deletion of strictly dominated strategies. A relevant question is: does the order in which we delete the strategies matter? For strictly dominated strategies, the answer is no. However, if we iteratively delete weakly dominated strategies, the answer may be yes, as the following example shows. In particular, there can be many "reasonable" predictions for outcomes of games according to iterative weak dominance. Let a=3,x=4,b=4,c=5,y=3,z=3,w= 3. (a) Show that M is a weakly dominated strategy for player 1. What strategy weakly dominates it? (b) After deleting M, we are left with a 2×2 game. Show that in this smaller game, strategy R is weakly dominated for player 2 , and delete it. Now, there are only 2 strategy profiles left. What do you predict as the outcome of the game (i.e., strategy profile played in the game)? (c) Return to the original game of part (4), but this time note first that U is a weakly dominated strategy for player 1 . What strategy weakly dominates it? (d) After deleting U, note that L is weakly dominated for player 2 , and so can be deleted. Now what is your predicted outcome for the game (i.e., strategy profile played in the game)?
Answers
The predicted outcome of the game, or the strategy profile played in the game, would then depend on the remaining strategies.
1. A strategy is considered strictly dominant for a player if it always leads to a higher payoff than any other strategy, regardless of the choices made by the other player. In this game, for player 1 to have a strictly dominant strategy, the payoff for strategy U must be strictly higher than the payoffs for strategies M and D, regardless of the choices made by player 2.
2. For player 2 to have a strictly dominant strategy, the payoff for strategy R must be strictly higher than the payoffs for strategies L and any other possible strategy that player 2 can choose.
3. To determine if any player has a strictly dominant strategy, we need to compare the payoffs for each strategy for both players. In this specific example, using the given values (a=2, b=3, c=4, x=5, y=5, z=2, and w=3),
4. The order in which strategies are deleted does matter when using iterative deletion of weakly dominated strategies. In the given example, when we delete the weakly dominated strategy M for player 1, we are left with a 2x2 game.
(c) In the original game of part (4), when we note that U is a weakly dominated strategy for player 1, we can look for a strategy that weakly dominates it. By comparing the payoffs, we can determine the weakly dominant strategy.
(d) After deleting U and noting that L is weakly dominated for player 2, we can delete it as well. The predicted outcome of the game, or the strategy profile played in the game, would then depend on the remaining strategies.

A real estate agent believes that the average closing costs when purchasing a new home is $6500. She selects 40 new home sales at random. Among these, the average closing cost is $6600. The standard deviation of the population is $120. At Alpha equals 0.05, test the agents claim.
Answers
The 95% cοnfidence interval fοr the average clοsing cοst is ($5,883.21, $7,316.79).
Hοw tο define this hypοtheses?Tο test the real estate agent's belief abοut the average clοsing cοst οf purchasing a new hοme, we will cοnduct a hypοthesis test. Let's define οur hypοtheses:
Null Hypοthesis (H0): The average clοsing cοst is $6,500.
Alternative Hypοthesis (Ha): The average clοsing cοst is nοt equal tο $6,500.
We will use a significance level οf α = 0.05.
Nοw, let's perfοrm the hypοthesis test:
Step 1: Set up the hypοtheses:
H0: μ = $6,500
Ha: μ ≠ $6,500
Step 2: Chοοse the apprοpriate test statistic.
Since we have a sample mean and want tο cοmpare it tο a knοwn value, we can use a οne-sample t-test.
Step 3: Determine the critical value(s) οr p-value.
Since the alternative hypοthesis is twο-sided, we will use a twο-tailed test. With a significance level οf α = 0.05 and a sample size οf n = 40, the degrees οf freedοm are (n-1) = 39. We can lοοk up the critical t-values in a t-distributiοn table οr use statistical sοftware. The critical t-values at α/2 = 0.025 are apprοximately -2.0227 and 2.0227.
Step 4: Calculate the test statistic.
The test statistic fοr a οne-sample t-test is given by:
t = (sample mean - hypοthesized mean) / (sample standard deviatiοn / sqrt(sample size))
In this case:
Sample mean (x) = $6,600
Hypοthesized mean (μ) = $6,500
Sample standard deviatiοn (s) is nοt prοvided, sο we can't calculate the test statistic withοut it.
Step 5: Determine the decisiοn.
Withοut the sample standard deviatiοn, we cannοt calculate the test statistic and make a decisiοn.
Given that the sample standard deviatiοn is nοt prοvided, we cannοt cοmplete the hypοthesis test. Hοwever, we can calculate the 95% cοnfidence interval tο estimate the true pοpulatiοn mean.
Tο find the 95% cοnfidence interval, we can use the fοrmula:
Cοnfidence interval = sample mean ± (critical value * standard errοr)
where the critical value is οbtained frοm the t-distributiοn table fοr a twο-tailed test at α/2 = 0.025, and the standard errοr is the sample standard deviatiοn divided by the square rοοt οf the sample size.
Let's assume the sample standard deviatiοn is $500 (an arbitrary value) fοr the calculatiοn.
Step 6: Calculate the 95% cοnfidence interval.
Using the assumed sample standard deviatiοn οf $500 and the sample size οf n = 40, the standard errοr is:
Standard errοr = sample standard deviatiοn / sqrt(sample size) = $500 / sqrt(40)
The critical value fοr a 95% cοnfidence interval with (n-1) = 39 degrees οf freedοm is apprοximately 2.0227.
Nοw we can calculate the cοnfidence interval:
Cοnfidence interval = $6,600 ± (2.0227 * ($500 / sqrt(40)))
Calculating the values, we get:
Cοnfidence interval = $6,600 ± $716.79
= ($5,883.21, $7,316.79)
The 95% cοnfidence interval fοr the average clοsing cοst is ($5,883.21, $7,316.79).
Cοmparing the hypοthesis test with the cοnfidence interval, if the hypοthesized mean οf $6,500 falls within the cοnfidence interval, it suggests that the null hypοthesis is plausible.
Hοwever, if the hypοthesized mean is οutside the cοnfidence interval, it prοvides evidence tο reject the null hypοthesis.
In this case, withοut the actual sample standard deviatiοn prοvided, we cannοt cοmpare the hypοthesized mean with the cοnfidence interval.

t and w are inversely proportional.
The equation of proportionality is t = 4/w
How will the value of t change if the value
of w is multiplied by 6?
Answers
Step-by-step explanation:
If t and w are inversely proportional, it means that as one variable increases, the other variable will decrease by the same factor. In this case, we have the equation t = 4/w, which means that if we multiply w by a certain factor, t will be divided by the same factor.
If we multiply w by 6, the new value of w will be 6 times the original value:
w' = 6w
To find the new value of t, we can substitute w' into the equation:
t' = 4/w'
t' = 4/(6w)
t' = 2/3w
So we see that t has been divided by 6/1 = 6. Therefore, the value of t will decrease by a factor of 6 if the value of w is multiplied by 6.

hr
kgliquid water m 2
hr
lb liquid water m 2
hr
liters liquid water m 2
hr
gallons liquid water b. How much liquid water fell on your garden? Express your answer using each of the following units:
Answers
The storm rainfall flux is 0.00127 m2/hr, 1.27 kg liquid water/m2hr, 2.8 lb liquid water/m2hr, 1.27 liters liquid water/m2hr, and 0.335 gallons liquid water/m2hr. The amount of liquid water fell on the garden is 80.6 L, 21.3 gallons.
Dimensions of outdoor vegetable garden = 2 m × 2 m
Storm rainfall = 0.8 inches of rain
Time of storm = 1 hr(
a) The rainfall flux is the amount of rainfall per unit area and unit time. It is given as:
Rainfall flux = (Amount of rainfall) / (Area × Time)
Given the area of the garden is 2 m × 2 m, and the time is 1 hr, the rainfall flux is:
Rainfall flux = (0.8 inches of rain) / (2 m × 2 m × 1 hr)
Converting inches to meters, we get:
1 inch = 0.0254 m
Therefore,
Rainfall flux = (0.8 × 0.0254 m) / (2 m × 2 m × 1 hr) = 0.00127 m/hr
Converting the rainfall flux to other units:
In kg/hr:
1 kg of water = 1000 g of water
Density of water = 1000 kg/m3
So, 1 m3 of water = 1000 kg of water
So, 1 m2 of water of depth 1 m = 1000 kg of water
Therefore, 1 m2 of water of depth 1 mm = 1 kg of water
Therefore, the rainfall flux in kg/hr = (0.00127 m/hr) × (1000 kg/m3) = 1.27 kg/m2hr
In lbs/hr:
1 lb of water = 453.592 g of water
So, the rainfall flux in lbs/hr = (0.00127 m/hr) × (1000 kg/m3) × (2.20462 lb/kg) = 2.8 lbs/m2hr
In liters/hr:
1 m3 of water = 1000 L of water
So, 1 m2 of water of depth 1 mm = 1 L of water
Therefore, the rainfall flux in L/hr = (0.00127 m/hr) × (1000 L/m3) = 1.27 L/m2hr
In gallons/hr:
1 gallon = 3.78541 L
So, the rainfall flux in gallons/hr = (0.00127 m/hr) × (1000 L/m3) × (1 gallon/3.78541 L) = 0.335 gallons/m2hr
(b) To calculate the amount of water that fell on the garden, we need to calculate the volume of water.
Volume = Area × Depth.
The area of the garden is 2 m × 2 m.
We need to convert the rainfall amount to meters.
1 inch = 0.0254 m
Therefore, 0.8 inches of rain = 0.8 × 0.0254 m = 0.02032 m
Volume of water = Area × Depth = (2 m × 2 m) × 0.02032 m = 0.0806 m3
Converting the volume to other units:
In liters:
1 m3 of water = 1000 L of water
Therefore, the volume of water in liters = 0.0806 m3 × 1000 L/m3 = 80.6 L
In gallons:
1 gallon = 3.78541 L
Therefore, the volume of water in gallons = 80.6 L / 3.78541 L/gallon = 21.3 gallons.

Reina's family is taking a road trip. Their car can travel no more than 304 miles without needing to refill the gas tank. They have traveled 221 miles since they last filled the gas tank. Reina knows that the inequality representing this situation is 221 + x < 304. Select from the drop-down menu to correctly interpret the solution of this inequality. Reina's family can drive ______ more miles before they need to refill the gas tank.
Answers
Solving the inequality, it is found that the correct interpretation of the solution is:
Reina's family can drive 83 more miles before they need to refill the gas tank.
The amount x of miles they can still travel is modeled by the following inequality:
\(221 + x \leq 304\)
To solve it, we treat it similarly to an equality, hence:
\(x \leq 304 - 221\)
\(x \leq 83\)
Hence:
Reina's family can drive 83 more miles before they need to refill the gas tank.
