Answer:

y = -8x + 23

Step-by-step explanation:

8y=x-16

we need to turn this into slope-intercept form by dividing 8 on both sides

y = x/8 - 2

to make a line perpendicular from another, we must make sure the slope is the negative reciprocal of the original line.

Right now, it's the same as the original. To make it a negative reciprocal, switch the places of the denominator and numerator and flip the signs

-8x is the negative reciprocal of x/8

Does it go through (4,-9)? No.

To make sure it goes through 4,-9, we change it's y-intercept.

Plug in the coordinate given (4,-9) in the y = -8x + b ( we removed -2 since it's not the right answer.

y = -8x + b

(-9) = -8(4) + b

-9 = -32 + b

-9 +32= -32 + b +32

23 = b

plug in b and we get our answer

y = -8x + 23

Answer:

Step-by-step explanation:

the total perimeter is 33 so all of the sides are equal to it.

33=3x+13+12

then combine like terms

33=3x+25

subtract from each side

(33)-25=(3x+25)-25

8=3x

Step-by-step explanation:

according to desmos

The measure of congruent angles X and Y of the hexagon are 135.

let the measure of the congruent angles of  X and Y be a

Then by the angle sum property of a hexagon sum of all the angle will be

U +V +W +X +Y +Z = 720

then 100 + 110+ 149 + 91 + a + a =720

2a = 720 - 450

2a = 270

Then a = 135

Hence the congruent angles X and Y are 135.

Answer:

Step-by-step explanation:

When you square a number, whether it's positive or negative, the square is always positive.  That is, a2 is positive whether a is positive or negative.  Examples:

12 = 1 x 1 = 1

(-1)2 = (-1) x (-1) = 1

52 = 5 x 5 = 25

(-5)2 = (-5) x (-5) = 25

Since the answer is always positive, you don't need the absolute value signs: |a2| = a2.

Answer:

C and D is the answer.

Step-by-step explanation:

If m∠5 = x°, according to the Corresponding Angle Theorem, m∠9 will equal the same, and because 9 and 12 are vertical angles, both of these will be the same measure.

A system having ΔG equal to zero means that the system is at equilibrium at standard conditions. This is option c. In a chemical reaction, ΔG represents the change in Gibbs free energy, which is a measure of the energy available to do work.

When ΔG is equal to zero, it indicates that the system is balanced, with the forward and reverse reactions occurring at the same rate. At equilibrium, the concentrations of reactants and products remain constant over time. For example, consider the reaction A ⇌ B. Initially, if we have more A than B, the forward reaction will be favored until equilibrium is reached. At equilibrium, the rate of the forward reaction equals the rate of the reverse reaction, and the concentrations of A and B remain constant. In this case, ΔG is zero.

It is important to note that while a ΔG of zero indicates equilibrium, it does not provide information about whether the reaction is spontaneous or nonspontaneous. The spontaneity of a reaction is determined by the sign of ΔG. If ΔG is negative, the reaction is spontaneous, while a positive ΔG indicates a nonspontaneous reaction.

Step-by-step explanation:

The probability that a bridge hand will have exactly 2 queens is 0.45%.

To find the probability of getting a bridge hand with exactly 2 queens, we need to use the binomial probability formula. The formula is:

P(exactly k successes) = (n choose k) * p^k * (1-p)^(n-k)

Where:

n is the total number of trials

k is the number of successes in the trials

p is the probability of success in a single trial

In this case, the total number of trials is 13 (since a bridge hand consists of 13 cards), and the number of successes we want is 2 (since we want exactly 2 queens). The probability of success in a single trial is the probability of drawing a queen, which is 4/52 (since there are 4 queens in a deck of 52 cards).

Plugging these values into the formula, we get:

P(exactly 2 queens) = (13 choose 2) * (4/52)² * (48/52)¹¹

= (78) * (1/169) * (4/13)¹¹

= (4/169) * (4/13)¹¹

This simplifies to:

P(exactly 2 queens) = (4/169) * (4/13)¹¹

= (4/169) * (4/169)¹¹

= (4/169)¹²

The final probability is approximately 0.0045 or 0.45%. This means that the probability of getting a bridge hand with exactly 2 queens is quite low.

The variance for the given data set: Year 1 = 16%; Year 2 = 6%; Year 3 = -25%; Year 4 = -3% is 0.0344.

The variance given the following returns:

Year 1 = 16%, Year 2 = 6%, Year 3 = -25%, Year 4 = -3% is 0.0344.

In probability theory, the variance is a statistical parameter that measures how much a collection of values fluctuates around the mean.

Variance, like other statistical measures, is used to describe data.

A variance is a square of the standard deviation, which is a numerical term that determines the amount of dispersion for a collection of values.

Variance provides a numerical estimate of how diverse the values are.

If the data points are tightly clustered, the variance is small.

If the data points are spread out, the variance is large.For a given data set, we may use the following formula to compute variance:

\($$\sigma^2 = \frac{\sum_{i=1}^{N}(x_i-\mu)^2}{N-1}$$\)

Where \($$\sigma^2$$\) is variance, \($$\sum_{i=1}^{N}$$\) is the sum of the data set, \($$x_i$$\) is each data point, \($$\mu$$\) is the sample mean, and \($$N-1$$\) is the sample size minus one.

In the above question, we will calculate the variance for the given data set:

Year 1 = 16%; Year 2 = 6%; Year 3 = -25%; Year 4 = -3%.

\($$\mu=\frac{(16+6+(-25)+(-3))}{4}=-1.5$$\)

Using the formula mentioned above,

\($$\sigma^2 = \frac{\sum_{i=1}^{N}(x_i-\mu)^2}{N-1}$$$$\)

=\(\frac{[(16-(-1.5))^2 + (6-(-1.5))^2 + (-25-(-1.5))^2 + (-3-(-1.5))^2]}{4-1}$$\)

After solving this expression,

\($$\sigma^2=0.0344$$\)

The maximum Number of  scholars in each row is 12. This means that the  scholars can be arranged in rows with an equal number of  scholars, and each row can have a  outside of 12  scholars.

To find the maximum number of  scholars in each row, we need to determine the  topmost common divisor( GCD) of the total number of  scholars in each section. The GCD represents the largest number that divides all the given  figures unevenly.  

Given that there are 24, 36, and 60  scholars in the three sections, we can calculate the GCD as follows    Step 1 List the  high factors of each number  24 =  23 * 31  36 =  22 * 32  60 =  22 * 31 * 51    

Step 2 Identify the common  high factors among the three  figures  Common  high factors 22 * 31    Step 3 Multiply the common  high factors to find the GCD  GCD =  22 * 31 =  4 * 3 =  12

We should apply the equation for the generic sine graph since we wish to determine the equation of the graph.

y = A sin (Bx + C) + D

where:

B = 2π/T, where T is the period, and

A is the amplitude.

A = [absolute maximum - absolute minimum]/2

A = [2.5 - 1.5] / 2

A = 1/2

B = 2π/T

where T = π (from  the graph)

B = 2π/T

B = 2π/(π)

B = 2

C = 0

D = vertical shift = -2

Step-by-step explanation:

Jacob is trying to sound more impressive knowing that Edward has more cords per hour. The writers of the question wouldn't say "trying to SOUND more impressive" if Jacob actually WAS more impressive. But maybe that's what they want you to think. If you take the 5 cords of Edward and divide it by the eight hours that it takes him to do you will notice he has an average of 0.625 cords per hour. And if you take a look at Jacob's average you immediately notice that he has an average of ABOVE 1. Jacob has an average of 1.62 cords per hour.

Now, the smallest side has a length of 10.

Let the hypotenuse be x + 2 while the other unknown side will be x since they are consecutive even integers.

Thus, using Pythagoras theorem we have;

(x + 2)² = 10² + x²

Expanding the bracket gives;

x² + 4x + 4 = 100 + x²

The answer is: 1.1454

The given function is sec (50°58'23") and we have to use a calculator to evaluate it. For this function, we have to use the formula: sec (θ) = 1/cos (θ).

We know that θ = 50°58'23" and this value should be converted into decimal form. To convert this value into decimal form, we will use the following formula :Degree measure + (Minute measure/60) + (Second measure/3600)θ = 50°58'23"θ = 50 + (58/60) + (23/3600)θ = 50.9731Therefore, sec (50°58'23") = 1/cos (50.9731)By using a calculator, we can get the value of cos (50.9731) which is 0.8722.

Now, substitute the value of cos (50.9731) in the above equation :sec (50°58'23") = 1/cos (50.9731)sec (50°58'23") = 1/0.8722sec (50°58'23") = 1.1454Therefore, the value of sec (50°58'23") is 1.1454 (rounded to four decimal places).
