You hit a tennis ball with an initial vertical velocity of 25 m/s. The ball leaves the tennis racket 2 meters above the ground, h_o. How much time does your opponent have before the ball hits the ground on the other side of the net, h(t)? Use h(t) = -5t^2 + v_0t + h_0 where h(t) is the height of a tennis ball being hit h_0 is the initial height v_0 is the velocity in meters/second after time (t) in seconds
Answer:
here
Step-by-step explanation:
Solving a quadratic equation, it is found that your opponent has 5.08 seconds to react before the ball hits the ground on the other side of the net.
What is the quadratic equation for the ball's height?It is given by:
[tex]h(t) = -5t^2 + v_0t + h_0[/tex]
In which:
[tex]v_0[/tex] is the initial velocity of the ball.[tex]h_0[/tex] is the initial height of the ball.You hit a tennis ball with an initial vertical velocity of 25 m/s. The ball leaves the tennis racket 2 meters above the ground, hence [tex]v_0 = 25, h_0 = 2[/tex].
Then, the equation is:
[tex]h(t) = -5t^2 + 25t + 2[/tex]
It hits the ground when h(t) = 0, hence:
[tex]-5t^2 + 25t + 2 = 0[/tex]
The solutions are h = 5.08 and h = -0.08.
Since time is a positive measure, your opponent has 5.08 seconds to react before the ball hits the ground on the other side of the net.

Harry’s tv plan cost 49.99 per month plus 3.49 per first run movie how many first run movies can he watch if he wants to keep his monthly bill to be a maximum of 100
Answer:
He can watch 14 first run movies to keep his monthly bill to be a maximum of $ 100.
Step-by-step explanation:
Given that Harry’s TV plan cost $ 49.99 per month plus $ 3.49 per first run movie, to determine how many first run movies can he watch if he wants to keep his monthly bill to be a maximum of $ 100, the following calculation must be performed:
100 - 49.99 = 50.01
50.01 / 3.49 = X
14.32 = X
49.99 + (3.49 x 14) = 98.85
Thus, he can watch 14 first run movies to keep his monthly bill to be a maximum of $ 100.

Coffee cans are to be filled with 16 oz. of coffee. The mean content of cans filled on a production line is monitored. It is known from past experience that the contents have a Normal distribution with a known standard deviation of 0.1 oz. A sample of 9 cans is taken every hour and their mean content is measured
a) Set up the hypotheses to test whether the mean content is 16 oz. Should the alternative be one-sided or two-sided? Why?
b) Give a decision rule in terms of the sample mean for a 0.05-level test.
c) If the true mean content during that the test derived in (b) will correctly detect this deviation from the target value of 16 oz? particular period is 16.1 oz., what is the probability
Answer:
a) H0: μ= 16 against the claim Ha: μ≠ 16
b) H0 will be rejected if it does not lie in the interval [15.934; 16.065 ]
c) 0.8531
Step-by-step explanation:
a) The null and alternate hypothesis are
H0: μ= 16 against the claim Ha: μ≠ 16
The test chosen is two sided because the cans have more or less content than 16 oz.
b) Here n = 9 , σ= 0.1 and α 0.05 and z∝/2 = ± 1.96
z∝/2 = x − µ/ σ/√n
z ∝/2= x-16/0.0333
± 1.96 *0.33= x-16
± 0.0653= x- 16
or x= 16± 0.0653
x= 15.934; 16.065
H0 will be rejected if it does not lie in the interval [15.934; 16.065 ]
c) The probability can be computed by transforming x into z
z= x-µ/ σ/√n
z= 15.934-16.1 /0.1/√9
z= [−4.95]
z2= x-µ/ σ/√n
z= 16.065-16.1 /0.1/√9
z2=[ −1.05]
P (15.934<x< 16.065 )= P (−4.95, −1.05)
=P ( z < −4.95 ) + P ( z > −1.05)
= 0+ 0.3531+0.5
= 0.8531

Solve for x
[tex]x = 180 - 50 - 55[/tex]

find the area of a circle if its circumference is 10 pi
Answer:
25π
Step-by-step explanation:
pi's symbol is π, which will be used sometimes to make it easier later
The circumference is equal to diameter multiplied by pi. (Diameter is the length across the circle, radius the center of the circle to an edge point aka. half the diameter, and circumference is the edge length aka. perimeter of the circle.)
We can then remove the pi off the 10, as the diameter multiplied by pi is the circumference, so the diameter is 10.
Half of 10 is 5, the radius.
The formula for area of a circle is radius squared times pi, remember easily by π r ^2
We can plug in the radius into the formula to get
π 5 ^2
And finish it by solving the square root to get
π 25
25π

The r-value of the given data is 0.374.
What is a correlation coefficient?The correlation coefficient, denoted as r, is a statistical measure that describes the strength and direction of the linear relationship between two variables.
It ranges between -1 and +1, where -1 indicates a perfect negative correlation (inverse relationship), +1 indicates a perfect positive correlation (direct relationship), and 0 indicates no correlation between the variables.
We have,
First, we need to find the correlation coefficient (r) of the given data.
We can use the following formula to do this:
r = [n∑(xy) - (∑x)(∑y)] / [√{n∑x² - (∑x)²} √{n∑y² - (∑y)²}]
where n is the number of data points, x, and y are the respective variables, and ∑ denotes the sum of the values.
Using the given data, we can calculate the values as follows:
n = 5
∑x = 39
∑y = 53
∑(xy) = 442
∑x^2 = 483
∑y^2 = 1249
Substituting these values into the formula, we get:
r = [5(442) - (39)(53)] / [√{5(483) - (39)^2} √{5(1249) - (53)²}]
r = [2210 - 2067] / [√(2415) √(5660)]
r = 143 / (61.898 75.245)
r = 0.374 (rounded to three decimal places)
Therefore,
The r-value of the given data is 0.374.

Answer:
x=135
Step-by-step explanation:
The two angles are supplementary, meaning they both add up to 180°.
So to find the value of one angle, simply subtract 50 from 180.
180-50=130
So now we know that 130 is equal to the expression.
x-5=130
Add 5 to both sides.
x=135
