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) 
Answer:
sin b would be 4/5
Step-by-step explanation:
sine is the opposite leg/the hypotenuse
120 + 120 + X + X = 360
240 + 2X = 360
2X = 120
X = 60
