Aball is thrown from 4 feet off the ground with a vertical velocity of 30 feet per second.
write an equation to model the height of the ball: h = -16t 2 + a0 t + a1
complete the table.
time t in seconds 0 0.5 1 1.5 a2
height h in feet a3 a4 a5 a6 0

step-by-step explanation:

answer4 to the second power is 16

and 4 to the third power is 64,

1. 2

2. 11

3. 5

4. 6

5. 7

6. 5

7. -1

8. 1

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
