Answer:
<em>0m</em>
Step-by-step explanation:
Before the ball is thrown, it is at the ground level. At the ground level, the height is zero. Substitute h = 0 into the equation;
h(x)=-x^2+10x-16
0=-x^2+10x-16
x^2-10x+16 = 0
Factorize
x^2-8x-2x+16 = 0
x(x-8) - 2 (x-8) = 0
x-2 = 0 and x - 8 = 0
x = 2 and 8
At x = 2
h(2) = -2^2 + 10(2) - 16
h(2) = -4 + 4
h(2) = 0
<em>Hence the height of the ball at the time it is thrown is 0m</em>

Answer:
m = -5
Step-by-step explanation:
Simplify both sides of the equation.
4(m−2)=2(m−9)
(4)(m)+(4)(−2)=(2)(m)+(2)(−9)(Distribute)
4m+−8=2m+−18
4m−8=2m−18
Subtract 2m from both sides.
4m−8−2m=2m−18−2m
2m−8=−18
Add 8 to both sides.
2m−8+8=−18+8
2m=−10
Divide both sides by 2.
2m/2 = -10/2
m = -5
