4. I need help with question in the attached picture!

Arisa [49]

ANSWER

D. 13

EXPLANATION

We have

$f(x) = \frac{2x + 1}{x - 4}$

To find

${f}^{ - 1} (3)$

means we want to find an x-value whose image is 3.

$\frac{2x + 1}{x - 4} = 3$

We cross multiply,

$2x + 1 = 3(x - 4)$

Expand:

$2x + 1 = 3x - 12$

Combine like terms,

$3x - 2x = 12 + 1$

$x = 13$

$\therefore{f}^{ - 1} (3)= 13$

poizon [28]

Answer:

Step-by-step explanation:

Volume of cylinder can be calculated by using the formula V= pir^2h

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

A cylinder with radius 1 inch and height of 9 inch is given.

r=1,h=1,π=3.14.

Substituting the given values :

V=πr2h=π·12·9≈28.27433

Volume of cylinder rounded to nearest tenth is 28.27 cubic inches .

Use the figure to find x.

velikii [3]

Answer:

Step-by-step explanation:

The sides of a 30-60-90 triangle are in the ratio 1:√3:2

The side opposite the 30° angle is (12√6)÷2 = 6/√6.

The side opposite the 60° angle is √3×6/√6 = 6/√2 =3√2.

The sides of a 45-45-90 triangle are in the ratio 1:1:√2

The hypotenuse is 3√2, so the side opposite the 45° angle is 3.

x = 3
