Pls help question is on picture

Answer:

9/15 = 3/5 (simplified)

Step-by-step explanation:

In a right triangle, the cosine is the ratio of the adjacent side to the hypotenuse:

$\cos\theta = \frac{\text{adjacent}}{\text{hypotenuse}}$

The adjacent side is the side that makes up the angle but is not the hypotenuse.

I'm assuming the answer box should ask for cos(theta) rather than cos(x).

If f(×)=2×^2+3, then which of the following represent f(-1)?

eimsori [14]

To find the inverse of this function, we first need to replace f(x) with y.

y = 2x^2 + 3

Now, we swap x and y

x = 2y^2 + 3

Now, we solve for y.

-3

x - 3 = 2y^2

Sqrt both sides.

√(x - 3) = 2y

Divide by 2

√(x - 3)/2 = y

Replace y with f^-1(x)

√(x - 3)/2 = f^-1(x)

Just realized you were asking for f(-1), not f^-1(x)

Feels bad.

f(-1) = 2(-1^2 + 3)

f(-1) = 2(-1^5)

f(-1) = 2(-1)

I'm leaving the original answer in case you also need the inverse function. :)

There’s a picture so I don’t have to type out the question

Lorico [155]

For this case we have the following function:

$s (V) = \sqrt [3] {V}$

This function describes the side length of the cube.

If Jason wants a cube with a minimum volume of 64 cubic centimeters, then we propose the following inequality:

$s \geq \sqrt [3] {64}$

Rewriting we have:

$s \geq \sqrt [3] {4 ^ 3}\\s \geq4$

Answer:

Option B
