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

Work out these questions without a calculator and showing all working out

1) 6÷0.2 = 30

If 6/2=3 then 6/0.2=30 as the decimal place shifts one place.

2)8÷0.1 = 80

8/1=8 so shift the decimal place over once to make 80.

3)9÷0.3 = 30

9/3=3 so shift the decimal place over once to get 30.

4)4÷0.04 = 100

4/4=1 so shift the decimal place over twice to get 100.

5)7÷0.002 = 3500

7/2=3.5 so shift the decimal place over three times to get 3500

6)0.718÷0.2 = 3.59

718/2=359 so shift the decimal over three places for the 0.718 and then back over once for the 0.2

7)0.0141÷0.003 = 4.7

141/3=47 so shift the decimal over our times for the 0.0141 and then back over three times for the 0.003

8)0.24÷0.012 = 20

24/12=2 so shift the decimal point over once twice for 0.24 then back over three times for 0.012

9)1.625÷0.0013 = 1250

1625/13=125 so shift the decimal point over three times for the 1.625 and then back four times for the 0.0013

10)47.1÷0.15 = 314

471/15=31.4 so shift the decimal point over once for the 47.1 and then back over twice for the 0.15.

Hope this helps :)
