A ball was kicked into the air from a balcony 20 feet above the ground, and the ball’s height above the ground, in feet, t secon

Svet_ta [14]

$h(t)=20-16t^2+32t \\ \Downarrow \\ h(t)=-16t^2+32t+20 \\ \\
a=-16 \\ b=32$

The maximum height is the y-coordinate of the vertex (x,y) of the parabola.
First find the x-coordinate using the formula:
$x=\frac{-b}{2a}=\frac{-32}{2 \times (-16)}=\frac{-32}{-32}=1$

Now plug the value into the equation and find the y-coordinate:
$y=h(x)=h(1)=-16 \times 1^2+32 \times 1+20=-16+32+20=36$

The maximum height is 36 feet.

Consider a circle with a diameter of 5 centimeters. Which equation shows how the relationship between the circumference and the

mrs_skeptik [129]

Answer:

The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π = $\frac{C}{5}$ ⇒ answer C

Step-by-step explanation:

In any circle there is a constant ratio between the circumference of the circle and its diameter

This constant ratio is called π

∵ The formula of the circumference of a circle is C = π d,

where d is the diameter of the circle

- Divide both sides by d

∴ $\frac{C}{d}$ = π

- Switch the two sides

∴ π = $\frac{C}{d}$

∵ The diameter of the circle is 5 centimeters

∴ π = $\frac{C}{5}$

The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π = $\frac{C}{5}$
