First find the coordinate of the center:
(1,2)
Then find the value pf the radio, which is the distance
from the center to the perimeter:
r = 4.
Given center (s,t) and radius r, the formula o the equation is the following
$(x-s)^2+(y-t)^2=r^2$
We deduce the equation:
$(x-1)^2+(y-2)^2=16$

Can someone SMART actually help me

lisov135 [29]

The answer is 196/3 pi in^3. All you have to do is multiply 7x7, then you have to multiply that by 1/3 and 4, and you get 65.333333333. Then, you have to turn it into a fraction. You have to multiply 65 by 3, then add one, and you get 196/3 pi in^3.

The inverse, f'(x), of f(x) =

astraxan [27]

Step-by-step explanation:

Given

$f(x) = \frac{x + 5}{x}$

$f(2) = \frac{2 + 5}{2} \\ = \frac{7}{2}$

Now

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

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

Hope it will help :)❤

Julie wanted to earn money to attend a basketball camp. She started with a gift of money from her grandparents and then saved $2

adoni [48]

The equation would be y = 25x + 50

In order to find this equation, we need to know how much the gift from her grandparents was. To do so, we have to find out how much she's saved from dog walking.

Since she saves $25 a month for 7 months, we can find the total amount as:

25*7 = 175

Then we can subtract that from the total she has saved to find the amount for the gift.

225 - 175 = 50

Finally, we put the amount per month in the equation with the gift as the y intercept to create the equation above.
