Answer:
45
Step-by-step explanation:
Since
5 : 225 = 1 : X
Then we know
225/5 = X/1
Multiplying both sides by 1 cancels on the right
1 × (225/5) = (X/1) × 1
1 × (225/5) = X
Then solving for X
X = 1 × (225/5)
X = 45
Therefore
5 : 225 = 1 : 45
Answer:45
Step-by-step explanation:well all you do is divide 5 from 225
A truck that is 11 feet tall and 7 feet wide is traveling under an arch. The arch can be modeled by:
y=-0.0625x+1.25x +5.75 where x and y are measured in feet.
a) Will the truck fit under the arch? Explain (with numerical details).
BIRD
b) What is the maximum width that a truck 11 feet tall can have and still make it under the arch?
Answer:
Yes
8 ft
Step-by-step explanation:
The equation of the arch is
\(y=-0.0625x^2+1.25x+5.75\)
Differentiating with respect to \(x\) we get
\(\dfrac{dy}{dx}=-2\times 0.0625x+1.25=-0.125x+1.25\)
Equating with zero
\(0=-0.125x+1.25\\\Rightarrow x=\dfrac{-1.25}{-0.125}\\\Rightarrow x=10\)
Double derivative of the equation
\(\dfrac{d^2y}{dx^2}=-0.125<0\)
So, the function is maximum at \(x=10\)
\(y=-0.0625x^2+1.25x+5.75=-0.0625\times 10^2+1.25\times 10+5.75\\\Rightarrow y=12\)
The function is maximum at \((10,12)\)
So, the truck's center should be below the point \((10,12)\) for maximum width to pass through.
Now truck is 11 feet tall so \(y=11\)
\(11=-0.0625x^2+1.25x+5.75\\\Rightarrow -0.0625x^2+1.25x-5.25=0\\\Rightarrow x=\frac{-1.25\pm \sqrt{1.25^2-4\left(-0.0625\right)\left(-5.25\right)}}{2\left(-0.0625\right)}\\\Rightarrow x=6,14\)
The maximum width of the truck can be \(14-6=8\ \text{ft}\) if it is 11 feet tall.
So, the truck which has a width of 7 feet can fit under the arch.
you want to enclose a rectangular region with an area of 1200 square feet and a length of 40 feet, 50 feet, or 60 feet. find the perimeter for each possible region.
The circumference is 160 feet for a length of 40 feet. The perimeter is 200 feet for a length of 50 feet. The circumference is 240 feet for a length of 60 feet.
A rectangular region with a 1200 square foot area will have a different perimeter depending on how long it is. The perimeter will be 160 feet if the area is 40 feet long. The length of 40 feet is multiplied by four to get a final measurement of 160 feet. In a similar manner, if the area is 50 feet long, the perimeter will be 200 feet.
The length of 50 feet is multiplied by four to get a final result of 200 feet. Finally, the perimeter will be 240 feet if the area is 60 feet long. The length of 60 feet is multiplied by four to get a final measurement of 240 feet. A rectangular region with an area of 1200 square feet will therefore have a different perimeter depending on its length, with a length of 40 feet resulting in a perimeter of 160 feet, a length of 50 feet resulting in a perimeter of 200 feet, and a length of 60 feet resulting in a perimeter of 240 feet.

find all points having an x-coordinate of calculator
To find all points with a specific x-coordinate, you need to have the equation of the curve or the data points representing the graph. If you have an equation, you can substitute the desired x-coordinate into the equation and solve for the corresponding y-coordinate.
If you have data points, you can look for the points that have the specified x-coordinate.
For example, let's say you have the equation of a line: y = 2x + 3. If you want to find all points with an x-coordinate of 5, you can substitute x = 5 into the equation to find y. In this case, y = 2(5) + 3 = 13. So the point (5, 13) has an x-coordinate of 5.

Find an equation for the line tangent to the graph of the given function at the indicated point. 8 3) f(x): () = at at (4,2) X 1 4) f(x)=x2-x at (4, 12)
(a) tangent line to the graph of f(x) = x^3 at the point (4,2).
(b) equation of the tangent line to the graph of f(x) = x^2 - x at the point (4,12).
(a) To find the equation of the tangent line to the graph of f(x) = x^3 at the point (4,2), we need to find the slope of the tangent line at that point. We can do this by taking the derivative of f(x) with respect to x and evaluating it at x = 4. The derivative of f(x) = x^3 is f'(x) = 3x^2. Evaluating f'(x) at x = 4 gives us the slope of the tangent line. Once we have the slope, we can use the point-slope form of a linear equation to write the equation of the tangent line.
(b) Similarly, to find the equation of the tangent line to the graph of f(x) = x^2 - x at the point (4,12), we differentiate f(x) to find the derivative f'(x). The derivative of f(x) = x^2 - x is f'(x) = 2x - 1. Evaluating f'(x) at x = 4 gives us the slope of the tangent line. Using the point-slope form, we can write the equation of the tangent line.
In both cases, the equations of the tangent lines will be in the form y = mx + b, where m is the slope and b is the y-intercept.

Grace works as a salesperson at an electronics store and sells phones and phone accessories, and makes a fixed commission for each phone sale and a different fixed commission for each accessory sale. Yesterday Grace sold 18 phones and 21 accessories and made a total commission of $204. Today she sold 6 phones and 14 accessories and made a total commission of $82. Determine the price of each phone and the price of each accessory.
What's the commission for each phone and the commission for each accessory?
The commission for each phone exists $2 and the commission for each accessory exists $9.
How to find the price of each phone and the price of each accessory?Given: Commission on 18 phones and 21 accessories = $204
commission on 6 phones and 14 accessories = $82.
Let the commission of each phone be P and the accessory be A.
From the given information, we get
18P + 21A = 204
6P + 7 A = 68 -----(1)
6P + 14 A = 82 ------(2)
By substitution of (1) in equation (2),
⇒ 68 - 7A + 14A = 82
simplifying both of the above equations we get
⇒ 7A = 14
⇒ A = 2
The value of A = 2.
Commission of each accessory = $2
To estimate the commission on each phone:
6P + 7 x 2 = 68
⇒ 6P = 54
⇒ P = 9
Commission of each phone = $9

There were 28 boys on the boy's basketball team and 16 girls on the girl's basketball team last year. This year the number of boys decreased by 8% but the number of girls increased by 19%. Was there an increase or decrease in overall participation?
There is an increase in total participants.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
number of boys = 28
Number of girls = 16
Total participants = 28 + 16 = 44
Now, there is decrease in number of boys by 8%
= 28- 8% x 28
=28- 8/100 x 28
=28 - 0.08*28
=28 -2.24
= 25.76
and, there is 19% increase in number of girls
=16 + 0.19 x 16
=16 + 3.04
=19.04
So, total participants = 25.76 + 19.04
= 44.8

determine if the following statements are true or false and explain your reasoning for statements you identify as false if the null hypothesis that the means of four groups are all the same is rejected using anova at a 5% significance level, then... a. (5 points) we can then conclude that all the means are different from one another. b. (5 points) the standardized variability between groups is higher than the standardized variability within groups. c. (5 points) the pairwise analysis will identify at least one pair of means that are significantly different.
The given null hypothesis statement a. true, statement b. true and finally statement c. true.
a. False. Rejection of the null hypothesis using ANOVA only tells us that at least one group mean is different from the others, but it doesn't necessarily mean that all means are different from each other. Additional post-hoc tests, such as Tukey's HSD or Bonferroni, are needed to identify which specific means are different from each other.
b. True. If the null hypothesis is rejected using ANOVA, it means that there is significant variability between the groups. This variability is measured by the F-statistic, which is the ratio of between-group variability to within-group variability. A high F-statistic indicates that the standardized variability between groups is higher than the standardized variability within groups.
c. True. If the null hypothesis is rejected using ANOVA, it means that there is at least one significant difference between the means of the groups. Pairwise comparisons can be conducted using post-hoc tests to identify which specific pairs of means are significantly different. However, it's important to adjust the significance level for multiple comparisons to avoid making Type I errors.

Determina la velocidad y la distancia total recorrida por un móvil que se desplaza con trayectoria parabólica, tomando en cuenta que su velocidad inicial es de 50 m/s y el ángulo de lanzamiento es de 81º. Ayuda porfavor
Answer:
First of all, in a parabolic motion, there are two coordinates, horizontal and vertical. That means we need to find the distances and velocities of both coordinates.
We know that \(v_{0}=50 m/s\) and \(\theta = 81\°\). So, we can already find the initial velocity for both coordinates.
\(v_{0_{y} } =v_{0} sin(\theta) = 50 (sin81\° ) \approx 49.4 m /s\\v_{0_{x} } =v_{0} cos(\theta) = 50 (cos81\° ) \approx 7.8 m/s\)
Which makes totally sense, beacuse the angle of shooting is near 90°, as a result, the projectile will cover more vertical distance than horizontal distance.
Now, we know that a parabolic motion divides into two congruent part, when going up and when going down. Also, when the projectile reaches the maximum height, the vertical velocity there is null. So, we use this information to find the maximum time.
\(v_{y}=v_{0_{y} } +gt\\ 0= 49.4 + (-9.8)t\\t_{max} =\frac{-49.4}{-9.8} \approx 5.04\)
So, the projectile takes 5.04 seconds to reach the maximum height. The total time of the whole parabolic motion would be double (due to the symmetry)
\(t=2(5.04) =10.08\)
Therefore, the projectile travels 10.08 seconds in total.
Now, we can find the maximum height reached by the projectile.
\(v_{f}=v_{0_{y} }+2gh\\ 0= 49.4+2(-9.8)h\\h=\frac{-49.4}{-19.6} \approx 2.5\)
So, the maximum height reached is 2.5 meters. The total vertical distance of the movement is 5 meters (due to the symmetry).
Now, we just need to find the horizontal distance.
\(x=v_{0_{x} } t= 7.8(10.08)=78.62\)
The total horizontal distance traveled is 78.62.
At last, the final speed when the projectile reaches the ground after being launched is the same as the initial, beacuse the movement is symmetric.
