The population of a town increased by 10% per year in 2009, 2010, and 2011. If the population of the town at the beginning of 20
sattari [20]
Assuming that the population follows an exponential function, the it will take the form:
y=a(bˣ)
where:
a=initial value
b=growth factor
x=time
thus plugging our values in the equation we get:
y=40000(1.1ˣ)
thus the population in 2011 when t=3 will be:
y=40000(1.1³)
y=53240

A large beach ball has a diameter of 4.14 feet. How much air can fill the ball?
aalyn [17]

The beach ball can hold 37.15 cubic feet of air

<u>Solution:</u>

Given that the beach ball has a diameter of 4.14 feet

We are asked to find how much air can fill the ball. This means that we have to find the volume of the ball

<em><u>Finding volume of ball:</u></em>

Given diameter = 4.14 feet

We know that radius is half of diameter

radius = \frac{diameter}{2}

radius = \frac{4.14}{2} = 2.07

Since ball is a sphere, Volume of sphere is given as:

volume of sphere = \frac{4 \pi r^3}{3}

By substituting the value of radius we get,

v = \frac{4 \pi \times 2.07^3}{3}\\\\v = \frac{4 \times 3.14 \times 8.869743}{3}\\\\v = 37.15

Hence the beach ball can hold 37.15 cubic feet of air

Snowcat [4.5K]

This makes no sense.. the question doesn’t state how much he sold. It only states what he had and how much he sold them for.

Given the following functions:
andrew-mc [135]

Answer:

x^2 - 6x + 9.

Step-by-step explanation:

f(x) = x^2 and g(x) = x - 3.

To find f(g(x))  we replace the x in f(x) by g(x).

f(g(x)) = (x - 3)^2

= x^2 - 6x + 9.
