Answer:
The height is 5.
Step-by-step explanation:
Volume = L x W x H
L= 10
W= 5
H= ?
10 x 5 x ?
10 x 5 = 50
50 x ? = 250
We know 50 x 2 = 100
So 50 x 4 = 200
So 50 x 5 will = 250
10 x 5 x 5
10 x 5 = 50
50 x 5 = 250
Rearranging to check work
5 x 5 x 10
5 x 5 = 25
25 x 10 = 250
I was right
Hope this answers your question.
Height = 5cm
This is because
L=10
W=5
10 x 5 = 50
50 x ? = 250
---- ------
50 50
? = 5
The height is 5

Hope this help!!!
f(x) = (x - 4)^2 - 5
Vertex (4 , -5)
This function opens upward and has min. value = -5
So range y >= - 5
So answer is A. -5 <= f(x) < ∞
