The answer is = 1 + sin x

Explanation

we need

a^2 - b^2 = (a+b) (a-b)

we use

cos^2 x + sin^2 x = 1

cos^2 x = 1 - sin^2 x = ( 1 + sin x) ( 1 - sin x )

therefore

cos ^2 x over 1 - sin x = 1+ sin x

The formula V = Bh, where B represents the area of the base, can be used to find the volume of a cylinder. Which formula is equi

cluponka [151]

ANSWER

C) V=πr²h

EXPLANATION

The formula for calculating the volume of a prism is

$V = Bh$

where B represents the area of the base and h represents the height of the prism.

A cylinder is a prism with a circular base.

Therefore area of the base is

$B = \pi \: {r}^{2}$

Therefore the volume of the cylinder is

$V = \pi \: {r}^{2} h$

The correct choice is C.

Answer:

Step-by-step explanation:

For the graph to represent a function, no vertical line may intersect it in more than one place. This graph does not pass the "vertical line test" so does not represent a function.

Solve for x : x over 4 + 10 = 16

Alekssandra [29.7K]

Hi! X = 2
Because 4 + 10 = 14. 16-14 = 2
x =2
Does this make sense?
