Answer:

$40

Step-by-step explanation:

we know that

The linear equation in slope intercept form i equal to

y=mx+b

where

y is the amount of her mother's donation

x is the number of miles that Melissa walks

where

m is the slope

b is the y-intercept

In this problem

The slope is

m=\$2\ per\ mile

The y-intercept is

b=\$10

substitute

y=2x+10

so

For x=15 miles

substitute

y=2(15)+10=\$40

Find the critical points of the function and use the First Derivative Test to determine whether the critical point is a local mi
Andre45 [30]

Answer:

Critical points are 1 and -1

Maximum at x=1

Minimum at x=-1

Step-by-step explanation:

We are given that a function

f(x)=3tan^{-1}(x)-\frac{3}{2} x+5 on (-\infty,\infty)

We have to find the critical points of the function.

To find the critical point we will differentiate function w.r.t x and then substitute f'(x)=0

f'(x)=\frac{3}{1+x^2}-\frac{3}{2}

\frac{d(tan^{-1}x)}{dx}=\frac{1}{1+x^2}

f'(x)=0

\frac{3}{1+x^2}-\frac{3}{2}=0

\frac{3}{1+x^2}=\frac{3}{2}

1+x^2=2

x^2=2-1=1

x=\pm1

Therefore, the critical points of the given function are 1 and -1.

f(0)=3-\frac{3}{2}=\frac{3}{2}

f'(1)=0

f'(2)=\frac{3}{5}-\frac{3}{2}=-\frac{9}{10}

When we goes from 0 to 2 then the sign of derivative  change from positive to negative .Therefore, function has local maximum at x=1.

f(-2)=\frac{3}{5}-\frac{3}{2}=-\frac{9}{10}

f(-1)=0

f(0)=\frac{3}{2}

When we goes form -2 to 0 then the sign of derivative change from negative to positive .Hence , function has local minimum at x=-1

Hence, critical points are local maximum and local minimum .

Liang has a goal of walking at least 18 miles. She walks at a rate of 4 miles per hour. Which inequality can Liang use to find h
stich3 [128]

Answer:

F (4h>18)

How To Do It:

She's walking at a rate of 4 miles per hour. Which means that you would be multiplying 4 by the amount of hours Liang walks(4h). The next part of the inequality is the sign and the other value. To get this from the equation we see that it says she must walk at least 18 miles. Meaning that the 4h will always be greater than the 18 that is on the other side.
