Answer:
Micah make 616066.97 $ over seven years
Step-by-step explanation:
This increase is in the form of a geometric progression.
Micah takes a job with a starting salary of $78,000
First term of GP = $78,000
He earns a 4% increase each year
Common ratio
Sum of n terms of GP with first term a and common ratio r.
How much does Micah make over seven years, so wee need to find sum of GP when n = 7.

Take derivitive
note
the derivitive of sec(x)=sec(x)tan(x)
so
remember the quotient rule
the derivitive of
so
the derivitive of
so now evaluate when t=pi
we get
sec(pi)=-1
tan(pi)=0
we get
slope=1/pi
use slope point form
for
slope=m and point is (x1,y1)
equation is
y-y1=m(x-x1)
slope is 1/pi
point is (pi,1/pi)
y-1/π=1/π(x-π)
times both sides by π
πy-1=x-π
πy=x-π+1
y=(1/π)x-1+(1/π)
or, alternately
-(1/π)x+y=(1/π)-1
x-πy=π-1
