Answer:
Step-by-step explanation:
Given
h varies as

Above h represents the height of object at any instant t
For example at t=0
h=190 ft
At t=1 s
h=-16+64+190=238 ft
For maximum height differentiate h w.r.t time

Put
to get maximum height

t=2 i.e. at t= 2 s h is maximum
h at t=2 s

Answer:
6x^2+9x-6
Step-by-step explanation:
(3x+6)(2x-1)=6x^2+12x-3x-6=6x^2+9x-6
Answer:
4704 in²
Step-by-step explanation:
We are given that,
We are asked to to find the surface area of the cube.
Surface area generally refers to total surface area .

- a denotes edge of the cube.
→ Surface area of cube = 6 × (28)² in²
→ Surface area of cube = 6 × 784 in²
→ <u>Surface area of cube = 4704 in²</u>
<u>Surface</u><u> </u><u>area</u><u> </u><u>of</u><u> </u><u>cube</u><u> </u><u>is</u><u> </u><u>4704 in²</u><u>.</u>
