Answer:

I'll give you the answers for 1 - 5: 1). 24, 2).19, 3)10, 4)13, 5)-17

Step-by-step explanation:

You simply substitute the corresponding values for the corresponding function:

f(6) if f(x) = 4x so, f(6) = 4(6) = 24

Another example:

f(5) if f(x) = 3x - 2 so, f(5) = 3(5) - 2 = 15 - 2 = 13

A sector with a radius of 8 cm has an area of 56pi cm2. What is the central angle measure of the sector in radians?

Maurinko [17]

Answer:

$\frac{7\pi}{4}$ .

Step-by-step explanation:

Given information:

Radius of circle = 8 cm

Area of sector = $56\pi\text{ cm}^2$

Formula for area of sector is

$A=\dfrac{1}{2}\theta r^2$

where, r is radius and $\theta$ is central angle in radian.

Substitute $A=56\pi$ and r=8 in the above formula.

$56\pi=\dfrac{1}{2}\theta (8)^2$

$56\pi=\dfrac{64}{2}\theta$

$56\pi=32\theta$

$\dfrac{56\pi}{32}=\theta$

$\dfrac{7\pi}{4}=\theta$

Therefore, the measure of the sector in radians is $\frac{7\pi}{4}$ .
