Determine the zeros of r=2sin5theta
vazorg [7]

Answer:

\theta=\frac{n\pi}{5}

Step-by-step explanation:

You have the following function:

r=2sin5\theta          (1)

In order to find the zeros of the function you equal to zero the equation (1), and then you solve for θ:

2sin5\theta=0\\\\sin5\theta=0\\\\5\theta=sin^{-1}(0)=n\pi;\ \ \ \ n=0,1,2,3,..\\\\\theta=\frac{n\pi}{5}

Then, there are infinite zeros for the function of the equation (1), because n has infinite positive integers values.

A. (m+n)(x)=
5x+4+6x-9=
11x-5

B. (mn)(x)=
(5x+4)(6x-9)=
30x^2+24x-45x-36=
30x^2-21x-36

C. basically sub n(x) for x in m(x)
m(n(x))=
5(6x-9)+4=
30x-45+4=

The volume of a cylinder is 980pi in3. The radius is 7 in. What is its height?
Dovator [93]

Answer:

D) 20 in

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h  where r is the radius and h is the height

Substituting what we know

980 pi = pi (7)^2 h

Divide each side by pi

980 pi /pi= pi 49 h/pi

980 = 49h

Divide each side by 49

980/49 = 49h/49

20 =h
