Mathematics

a>-40

Step-by-step explanation:

$4 + 2(a + 5) < - 2 - a - 4 \\ 4 + 20 + 10 < - 2 - a - 4 \\ 34 < - 2 - a - 4 \\ 34 + 2 < - 2 - a + 4 + 2$

$36 < - a - 4 \\ 36 + 4 < - a - 4 + 4 \\ 40 < - a \\ \frac{40}{ - 1} < \frac{ - a}{ - 1}$

a 40

Step1 : Use 2 to open the bracketAdd 4+10+20Subtract +2 from both sidesAdd + 4 to both sidesDivide both sides by -1 and flip the sign.

When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.

0 = -(x-2)^2 + 16

(x-2)^2 = 16

x-2 = 16

x-2 = 4

x = 6

This means the ball will hit the ground 6 seconds after Amir threw it.
