the function h=-16t^2+48t represents the height h (in feet) of a kickball t seconds after it is kicked from the ground

Julli [10]

Answer:

36 feet

Step-by-step explanation:

Given

$h(t) = -16t^2 + 48t$

Required

Determine the maximum height attained

First, calculate the time to reach maximum height;

In a quadratic equation;

$y = ax^2 + bx + c$

The maximum is:

$x = -\frac{b}{2a}$

So, we have:

$t = -\frac{b}{2a}$

Where

$a = -16; b = 48$

So:

$t = -\frac{b}{2a}$

$t = -\frac{48}{2 * -16}$

$t = -\frac{48}{-32}$

$t = \frac{48}{32}$

$t = 1.5$

The maximum height is at: $t = 1.5$

So, we have:

$h(t) = -16t^2 + 48t$

$h_{max}=-16 * 1.5^2 + 48 * 1.5$

$h_{max}=36$

Express 3cm: 3m in the ratio of its simplest form

Dmitry_Shevchenko [17]

Answer:

1cm:100cm

Step-by-step explanation:

You have to convert the ratio into the same unit (I chose cm). If there are 100cm in a metre, there will be 300cm in 3m.

That leaves you with the ratio 3cm:300cm. To simplify, divide both sides by three leaving you with 1cm:100cm
