<u>Answer:</u>
The correct answer is 60 feet / second.
<u>Step-by-step explanation:</u>
We are given the height of a ball which is falling from a height of 280 feet for 3 seconds.
We are to find the ball's rate of fall during the first 3 seconds.
For that, we will take the difference between the heights and divide it by the time.
Ball's rate = = 60 feet / second
After combining like terms and simplifying we get
Step-by-step explanation:
We need to combine like terms to simplify the expression:
Like terms: The terms are like when they have same variable and same exponent.
Solving:
So, After combining like terms and simplifying we get

Answer: a) b)
c)
d)
Step-by-step explanation:
Since f is an exponential function.
So, it is expressed as
Here f is the present value
p is the initial value
r is the rate of growth per time period
t is the time period.
(a) b represents the 1-unit growth factor for f.
(b) c represents the n n-unit growth factor for f.
(c) d represents the m m-unit growth factor for f.
Write a formula that expresses c in terms of b.
Since
Hence, a) b)
c)
d)
