Simplifying
h(t) = -1t2 + -2t + 30
Multiply h * t
ht = -1t2 + -2t + 30
Reorder the terms:
ht = 30 + -2t + -1t2
Solving
ht = 30 + -2t + -1t2
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Divide each side by 't'.
h = 30t-1 + -2 + -1t
Simplifying
h = 30t-1 + -2 + -1t
Reorder the terms:
h = -2 + 30t-1 + -1t
The answer C make more sense.
Answer:
50 ft³
Step-by-step explanation:
As your question is incomplete
Assuming diagram in the attachment shows a triangular prism:
(a) Calculate the volume of the prism if l = 5 ft.
A triangular prism has the same triangular cross-section throughout its length.
Volume = area of cross-section × length
= 10 ft² × 5 ft
= 50 ft³
