Answer:
No, she used the diameter instead of the radius measure.
Step-by-step explanation:
we know that
The volume of the sphere is equal to
we have
----> the radius is half the diameter
substitute
If Lucky received 56 of 180 votes cast, she received 56. The answer is in the question.
The '40 years' is not part of the question. It's just there to prove that
'2% each year' has been the experience for the past 40 years, so it's
a good number to use for the rate of growth, past or future.
So, at any number of years 'Q' after the beginning of "this period",
the population was or will be
Pop = (220,000) (1.02)^Q power.
(This equation is familiar from all of the bank-interest problems
the student has done in past math classes.)
In 10 years after the beginning of "this period",
Pop = (220,000) (1.02)¹⁰ = <em>243,800 </em>(or any reasonably close number)
A function with zeros -3 and 2 could be:
(x + 3)(x - 2) or x² + x - 6
Keep in mind that there are an unlimited number of functions that have these zeros, such as:
2(x + 3)(x - 2) or 2x² + 2x - 12
(x + 3)(x - 2)(x + 5) or x³ + 6x² - x - 30
Generally, the function just has to include the factors (x + 3) and (x - 2) to have the zeros -3 and 2.
