Using an exponential function, it is found that:
a) The doubling time of the salary is of approximately 20 years.
b) The salary will be of $160,000.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal.
The growth rate for this problem is:
r = 0.035.
The doubling time is t for which A(t) = 2A(0), hence:
t = 20 years.
You retire in 40 years, which is 2 doubling periods, hence the salary will be of:
40000 x 2 x 2 = $160,000.

Answer:
length=70cm
width=7cm
Step-by-step explanation:
total ratio=10 + 1
=11
length(2)=10/11 x 154 cm
=10 x 14cm
=140cm
one length is 140 cm/2=70cm
width(2)=1/11 x 154cm
=14cm
one width is 14cm/2=7cm
Hi there!
4y - 2(1 - y) = -44
Begin by distributing -2:
4y - 2(1) - 2(-y) = -44
Simplify. A negative times a negative equals positive.
4y - 2 + 2y = -44
Combine like terms:
6y - 2 = -44
Add 2 to both sides:
6y = -42
Divide both sides by 6:
y = -7
$21.82
