Answer:

C. Time since the person starts walking is the input.

D. t represents the input.

Step-by-step explanation:

The distance a person walks, d, in kilometers, is a function of time, t, in minutes, since the walk begins.

So, we can write d = f(t)

If the person is moving with constant speed, then the above function will be linear.

Now the true statements are

C. Time since the person starts walking is the input.

D. t represents the input.

All the other statements are false. (Answer)

Answer:

18π + 90

Step-by-step explanation:

The perimeter is the sum of quarter of the circumference and 2r , that is

P = 2πr + (45 + 45)

= 2 × π × 36 × $\frac{1}{4}$ + 90

= 2 × π × 9 + 90

= 18π + 90

A water balloon is launched in the air from a height of 12 feet and reaches a maximum height of 37 feet after 1.25 seconds. Writ

never [62]

The height of the balloon is given as h(t) = -16t² + 40t + 12 at 2 seconds, the height is 28 feet

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let h represent the height of the water balloon after t minutes, hence:

h(t) = -16t² + vt + h₀

Where h₀ is the initial height = 12 feet and v is the initial velocity, hence:

h(t) = -16t² + vt + 12

The height of 37 feet after 1.25 seconds, hence:

37 = -16(1.25)² + v(1.25) + 12

v = 40 m/s

h(t) = -16t² + 40t + 12

After 2 seconds:

h(t) = -16(2)² + 40(2) + 12

h(2) = 28 feet

The height of the balloon at 2 seconds is 28 feet
