number of people in the theater must be under 500 to meet fire safety regulations. What is the solution of this inequality, and what is it’s meaning?
A. 10x + 200 > 500; the new theater must have more than 30 seats in each row on the floor to meet fire safety regulations.

B. 10x + 200 < 500; the new theater must have fewer than 30 seats in each row on the floor to meet fire safety regulations.

C. 10x > 500; the new theater must have more than 50 seats in each row on the floor to meet fire safety regulations.

D. 10x < 500; the new theater must have fewer than 50 seats in each row on the floor to meet fire safety regulations.

Step-by-step explanation:

Let \:   \: \theta =  \sin^{ - 1}  (\frac{4}{5})  \\  \\  \therefore \:  \sin\theta = \frac{4}{5} \\  \\  \because \:  { \cos}^{2} \theta =1  - { \sin}^{2} \theta  \\  \\  \therefore \: { \cos}^{2} \theta  = 1 - (\frac{4}{5} )^{2}  \\ \\   = 1 -  \frac{16}{25}  \\  \\  =  \frac{25 - 16}{25}  \\  \\  =  \frac{9}{25}  \\  \\   \therefore \:{ \cos}\theta  = \pm \:  \frac{3}{5}  \\  \\  \because \:  \theta \: lie \: in \: the \: first \: quadrant \\  \\  \therefore \: { \cos}\theta  =  \:  \frac{3}{5}  \\ \\  \implies \theta =  { \cos}^{ -1 }  \: \frac{3}{5}\\\\\implies \theta =  { \cos}^{ -1 }  \: \frac{3}{5}= { \sin}^{ -1 }  \: \frac{4}{5} \\  \\  \therefore \:  \cos( \ {sin}^{ - 1}  \frac{4}{5} ) \\ \\ =  \cos( \ {cos}^{ - 1}  \frac{3}{5} )   \\\\ = \frac{3}{5}  \\  \\   \purple{ \boxed{\therefore \: \cos( \ {sin}^{ - 1}  \frac{4}{5} ) = \frac{3}{5}}}

What is the volume of a cylinder with the base radius of 10 units and a height of nine units?
Otrada [13]

Answer:

V = 2827.43\ units^3  or V = 900\pi\ units^3

Step-by-step explanation:

The volume of a cylinder is calculated by the following formula

V = \pi r^2 *h

Where r is the radius of the cylinder and h is the height

In this case we know that the radius r of the base is:

r=10\ units

and

h=9\ units

So the Volume is:

V = \pi (10)^2 *9

V = 900\pi\ units^3

V = 2827.43\ units^3
