Step-by-step explanation:
9y+7 + 7y-19 = 180
Y =12 degrees
When she cubed the number of flowering plants that means p^3 so the answer is not A or B
now take a look at C or D
both are p^3 + 2 which is right now lets solve it:
3^3 + 2 = 27 +2 = 29
so the answer is D :)))
i hope this is helpful
have a nice day
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.

If you mean by spectacles, it would cost Malcom about $3.60 for a pair.
