A banner is made of a square and a semicircle. The square has side lengths of 22 inches. One side of the square is also the diam
anastassius [24]
Assuming the square and the semicircle aren't merged somehow, and we need to calculate their full area, we should take into account:

Area of a square:
(Side length)² = 22² = 484 square inches

Area of a circle with a diameter of 22inch:
3'14 · (radius)² = 3'14 · 11² = 379'94 square inches

Since we have half a circle, the total areas to add will be:
1/2 · 379'94 + 484 = 673'97

A certain population of bacteria has an initial population of 225. the bacteria triples every hour. determine the multiplier tha
dimaraw [331]

Using an exponential function, it is found that the multiplier that would allow you to predict the population of bacteria after 2 hours is of 9.

<h3>What is an exponential function?</h3>

An exponential function is modeled by:

y = ab^x

In which:

  • a is the initial value.
  • b is the growth rate.

In this problem, the bacteria triples every hour, hence the rate of change is b = 3, and the equation is:

y = a(3)^x

Hence, after 2 hours:

y = a(3)^2 = 9a

Which means that the multiplier is of 9.
