Answer:

x/7 - 2 = y

Step-by-step explanation:

To find the inverse of a function, we switch f(x) and x and then solve for f(x). We thus have

x = 7f(x) + 14

subtract 14 from both sides to isolate the f(x) and its coefficient

x - 14 = 7 f(x)

divide both sides by 7 to isolate the f(x)

(x-14)/7 = f(x)

f(x) is synonymous with y here. so we havt

(x-14)/7 = y

This can also be written as

x/7 - 14/7 = y

x/7 - 2 = y

What is the radius of a sector

professor190 [17]

Answer:

$\frac{10}{3}$ units

Step-by-step explanation:

Recall that the area of a sector is $A=\frac{r^2\theta}{2}$ where $r$ is the radius and $\theta$ is the angle of the sector (measured in radians).

Therefore, the radius of the sector is:

$A=\frac{r^2\theta}{2}$

$\frac{100\pi}{27}=\frac{r^2(\frac{2\pi}{3})}{2}$

$200\pi=27r^2(\frac{2\pi}{3})$

$200\pi=r^2(\frac{54\pi}{3})$

$200\pi=r^2(18\pi)$

$\frac{200}{18}=r^2$

$\frac{100}{9}=r^2$

$\frac{10}{3}=r$

So, the radius of the sector is $\frac{10}{3}$ units.
