A certain forest covers an area of 2,000 square kilometers. Suppose that each year this area decreases by 6%. What is the functi

Trava [24]

The question gives you the formula to use, but it's printed wrong.
The 'x' is an exponent after the (1 + r).

All you have to do is take the formula, and write the numbers into it
that are also given.

The key thing to spot is that the forest is <u><em>decreasing</em></u>, so the 'r' is <u>negative</u>,
just as if you had money in a savings account and every year the bank took
6% <u>out</u> of it.

So the formula to use is    f(x) = P (1 + r) ^x

P = 2000
r = -0.06
      f(x) = 2000 (1 - 0.06)^x
         = <em>2000 (0.94)^x</em>

The amount left after 12 years is

   2000 (0.94)¹² =

   2000 (0.476) =<em> 951.8 square kilometers</em>.

Yuson used her calculator to solve the equation

Tpy6a [65]

Answer:

Rather than just multiplying 5/4 with 8, she has to multiply it with 3 + 8. She could put parentheses around the 3 + 8, according to PEMDAS, this would mean that the parenthesis must be solved before multiplication. The correct answer would be:

4/5x - 8 = 3

4/5x = 3 + 8

x = (3 + 8)5/4

x = 11 x 5/4

x = 55/4 or 13.75

A company makes a cone-shaped container with a height of 15 in. The area of its base is about 78.8in.2 Approximately what is the

MakcuM [25]

Answer:

Approximately the volume of cone-shaped container is <u>393 in³</u>.

Step-by-step explanation:

Given:

A company makes a cone-shaped container with a height of 15 in.

The area of its base is about 78.8 in².

Now, to get the cone-shaped container volume.

So, we find the radius first by using formula:

Let the radius be $r.$

<u><em>(Using the value π = 3.14)</em></u>

$A_{B}=78.8\ in^2.$

$A_{B}=\pi r^2$

$78.8=3.14\times r^2$

<em>Dividing both sides by 3.14 we get:</em>

<em>Using square root on both sides we get:</em>

$5.00=r$

$r=5\ in.$

Thus, the radius ( $r$ ) = 5 in.

<u>The height (</u> $h$ <u>) = 15 in.</u>

Now, to get the volume of the cone-shaped container we put formula:

$Volume=\pi r^2\frac{h}{3}$

$Volume=3.14\times 5^2\times \frac{15}{3} \\\\Volume=3.14\times 25\times 5\\\\Volume=392.50\ in^3.$

Therefore, approximately the volume of the cone-shaped container is 393 in³.
