Answer: 3/5

Step-by-step explanation:

First, you need to find the inverse of f(x)=2x+5 .

$f-1(x)= \frac{x}{2} -\frac{5}{2}$

Then, you'd plug in 8 into that equation, which I got $\frac{3}{5\\}$

Hope this helps :)

const2013 [10]

The number of pieces of card stock which would result upon the process repetition is; 256 pieces.

<h3>What is the number of card stock pieces resulting from the cutting process?</h3>

According to the task content, it follows that since, there are 8 pieces of the 8 inches per side cards initially, the resulting number of cards after carrying out the process of cutting cards into half five, 5 times is;

No of cards = 8 (2)⁵

No. of cards = 256 pieces.

The size of each of the cards in discuss provided that all cuts will be made along and not across the longer edge is; 8 by 1/4 inches.

Korvikt [17]

Answer: 6

Step-by-step explanation:

From the question, we are informed that a group of friends wants to go to the amusement park and that they have $94.25 to spend on parking and admission.

We are further told that Parking is $14.75, and tickets cost $13.25 per person, including tax. The equation that can be used to solve the number of people who can go to the amusement park would be:

= 14.75 + 13.25p

Since they've $94.25 to spend, the number of people that can go to the amusement park will be:

14.75 + 13.25p = 94.25

13.25p = 94.25 - 14.75

13.25p = 79.50

p = 79.50 / 13.25

p = 6

6 people can go to the amusement park

In 2010 the town of Applewood had an estimated population of 22,000 people, and its annual growth rate was estimated to be 1.8%.

sladkih [1.3K]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

P------> the population of Applewood

n-----> the number of years since 2010

we have

$P(n)=22,000(1.018^{n})$

using a graphing tool

see the attached figure

Verify each conclusion

a) The population of Applewood, P(n), equals 0 when n = 0

The conclusion is No

For n=0

The population is equal to P(0)=22,000 people

b) The behavior of the left end of the graph flattens out indicating that as n approaches negative infinity the population of Applewood approaches 0

The conclusion is Yes

see the graph

c) The behavior of the right end of the graph is upward indicating that as n approaches infinity the population of Applewood approaches infinity

The conclusion is Yes

see the graph
