Answers

The inverse function theorem says

$(\mathrm df^(-1))/(\mathrm dx)(16)=\frac1{(\mathrm df)/(\mathrm dx)(f^(-1)(16))}$

We have

$f(x)=x^2+4x-5$

defined on $x>-2$ , for which we get

$f^(-1)(x)=-2+√(x+9)$

and

$f^(-1)(16)=-2+√(16+9)=3$

The derivative of $f(x)$ is

$f'(x)=2x+4$

So we end up with

$(\mathrm df^(-1))/(\mathrm dx)(16)=\frac1{(\mathrm df)/(\mathrm dx)(3)}=\frac1{10}$

N - 4 = 3n + 6 Yikesss

Answers

Answer: n=-5

Step-by-step explanation:

Answer:

N=-5

Step-by-step explanation:

N - 4 = 3n + 6

Add 4 to both sides

n-4+4=3n+6+4

Simplify

n=3n+10

subtract 3n from both sides

n-3n=3n+10-3n

Simplify

-2n=10

Divide -2 from both sides

-2n/-2=10/-2

Simplify

n=-5

Joyce Flynn, an insurance agent, earned in her first week on the job a commission of $1,800. Her commission percent is 30 percent. Joyce's total sales for the week was:

Answers

if 1800 is the 30% of the total, so 1800 / .30 = 6,000

Using the provided information, it is determined that $6000 was Joyce's total weekly sales.

What does the percent mean?

Percent, which is a relative value used to denote hundredths of any quantity.
Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

What is the significance of percentage?

Comparing two amounts while rebasing the second amount to 100 is the simplest way to use percentages.

Given:

An insurance agent named Joyce Flynn made a commission of $1,800 in her first week on the job. She receives a 30% commission.

We need to find the total sales for the week.

Let, x = total commission

Since, 30% of total commission is 1800. So, total sales will be:

x = 1800/0.30 = 6000

Therefore, Joyce's total sales for the week is found to be $6000 by using the given data.
