Answer:

Step-by-step explanation:
We are given that
Initial velocity=30 ft/s
Initial position=
We have to write a mathematical model for height of the softball by using the position equation
The position equation on Earth's surface is given by

Where
Initial velocity
=Initial position
Substitute the values in the equation then, we get

Hence, the mathematical model for height of the softball is given by

Answer:
3.2 x 10^13
Step-by-step explanation:
(8x10^4)(4x10^8)
reorder the terms using the commutative property
(8x4)x(10^4x10^8)
multiply
32x (10^4 x 10^8)
= 32 x 10^4+8
= 32 x 10^12
now convert to scientific notation
=3.2 x 10^13
