Step-by-step explanation:
Ronin kicks a ball over the gate of the first floor balcony. The function h(t)=-36t^2+288t+9 can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet 1. Find the time in Devon which the ball reaches it maximum height
Answer: 4 seconds
Step-by-step explanation:
Given: The function [tex]h(t)=-36t^2+288t+9[/tex] can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.
Differentiate the given function with respect to t , we get
[tex]h'(t)=-36(2)t+288=-72t+288[/tex]
Put h'(t)=0
[tex]\Rightarrow\ -72t+288=0\Rightarrow\ t=\dfrac{288}{72}\\\\\Rightarrow\ t=4[/tex]
Also, [tex]h''(t)=-72<0[/tex]
By second derivative test, h(t) is maximum at t=4.
Hence, the time in Devon which the ball reaches it maximum height = 4 seconds

how do I find the volume of a cylinder with a missing variable
Answer: Write the equation with the "formula" with whatever you do have.
Volume = area of base times height.
V = πr²h
Step-by-step explanation: Sometimes they just want to see what you do with the information you have. Sometimes there is a hidden clue, like a puzzle.
C is directly proportional to D, when C-125 and D=5.
Write an equation to express C in terms of D.
Does 5.2 belong with irrational or rational numbers?
Answer:
The correct answer is "rational" . It is not an "integer" because it is a "decimal value". It is not "irrational" because the decimal value terminates and does not repeat.

If the bill is $100 and the tax rate is 10%, then the sales tax is how much money?
Answer:
$10
Step-by-step explanation:
10% of $100= $10 :)
Answer:
For example, if the sales tax amount is $6.88, and the before tax price is $100, then the decimal tax rate would be 0.0688 ($6.88 ÷ $100 = .0688 rounded).
Step-by-step explanation:

A blimp travels 255 feet in 1/2minute, 510 feet in 1/6 minute, and 3,060 feet in 1 minute.
is there or is there not a proportional relationship between the distance the blimp travels and the time it travels.
Answer:
We conclude that there is NOT a proportional relationship between the distance the blimp travels and the time it travels.
Step-by-step explanation:
We know if y varies directly with x, we get the equation
y ∝ x
y = kx
k = y/x
where k is called the constant of variation.
In our case we are given:
A blimp travels 255 feet in 1/2 minute
A blimp travels 255 feet in 1/2minute.here:
y = 255, and x = 1/2 = 0.5
so substituting y = 255 and x = 0.5 in the equation
k = y/x
k = 255 / 0.5
k = 510
A blimp travels 510 feet in 1/6 minute
here:
y = 510 , and x = 1/6
so substituting y = 510 and x = 1/6 in the equation
k = y/x
k = [510] / [1/6]
k = 3060
A blimp travels 3,060 feet in 1 minute
here
y = 3,060, and x = 1
so substituting y = 3,060 and x = 1 in the equation
k = y/x
k = 3,060 / 1
k = 3060
HERE IS THE VARIATION OF THE CONSTANT OF VARIATION:
A blimp travels 255 feet in 1/2 minute
k = 510
A blimp travels 255 feet in 1/2 minute
k = 3060
A blimp travels 3,060 feet in 1 minute
k = 3060
It is clear that the constant of variation does not remain constant.
Therefore, we conclude that there is NOT a proportional relationship between the distance the blimp travels and the time it travels.

Bart Simpson can skateboard 4 miles in 56 minutes. How many miles can he skateboard in 42 minut
Answer: 3 Miles
54 / 4 = He's going one mile every 14 minutes. Use unit rates i.e 1 mile for every 14 minutes to figure out that he would skate 3 miles in 42 minutes.
Answer:
3 miles
Step-by-step explanation:
The problem above is related to the topic on "Equivalent Ratios." In order to find the missing term in a proportion, you can use cross products.
Let n be the "missing term" or the number of miles that Bart Simpson can skateboard in 42 minutes.
[tex]\frac{4 miles}{56 min.}[/tex] = [tex]\frac{n}{42 min.}[/tex] 4 x 42 = 56n168 = 56n[tex]\frac{168}{56}[/tex] = n3 = nn = 3 milesTherefore, it takes 3 miles for Bart Simpson to skateboard in 42 minutes.

(x^2-5x+4) is the right answer.You know the given conditions for the triangle are fixed. You also know the unknown side length is fixed. What does this tell you about the two angles adjacent to the unknown side?
Answer:
The angles are complementary angles
Step-by-step explanation:
Given that a triangle has three sides and three angles
From the above question the unknown side of the triangle has a fixed value ( given ) hence the two angles adjacent to the unknown side will be complementary angles. this is because the sum of the angles of a triangle = 180°
Answer:
Because the given conditions (7 centimeters, 9 centimeters, and 74°) are fixed and the unknown side length is fixed, the angles adjacent to the unknown side must also be fixed.
