Answer:

yes

Step-by-step explanation:

For a relation to be a function each value of x in the domain must map to exactly one unique value of y in the range.

Since the relation is a straight line , then each value of x will only map to one unique value of y ( passes the vertical line test )

905.14 m³

Step-by-step explanation:

$Volume \: of \: sphere \\ = > \frac{4}{3} \pi {r}^{3} \\ = > \frac{4}{3} \times \pi \times {(6m)}^{3} \\ = > \frac{4}{3} \times \pi \times 216 {m}^{3} \\ = > 4 \times \pi \times 72 {m}^{3} \\ = > 4 \times \frac{22}{7} \times 72 {m}^{3} \\ = > \frac{6336}{7} {m}^{3} \\ = > 905.14 {m}^{3}$

Divide 20 by 3 to see how much she would wax in 1/5 of an hour.
20/3= 6.66666667
6.66666667 * 5 =

Two percent of Jennies skin cells were burned when she escaped from a fire. If

andreev551 [17]

$1.813*10^{12}$ cells of Jennies skin were not burned.

Step-by-step explanation:

Given,

Burned skin cells = $3.7*10^{10}$

This represents 2% of total skin cells.

Let,

x represents the total number of skin cells.

2% of x = $3.7*10^{10}$

$\frac{2}{100}x=3.7*10^{10}\\\\0.02x=3.7*10^{10}$

Dividing both sides by 0.02

$\frac{0.02x}{0.02}=\frac{3.7*10^{10}}{0.02}\\\\x=1.85*10^{12}$

Number of not burned cells = Total - burned

Number of not burned cells = $1.85*10^{12}-3.7*10^{10}$

Number of not burned cells = $1.813*10^{12}$

$1.813*10^{12}$ cells of Jennies skin were not burned.

Find the inverse function F -1 (X) for the given function F (X)

charle [14.2K]

<u>Solution for question 5:</u>

f(x) = 4x - 8

To find f^-1(x) write it as an equation:

y = 4x - 8

Then take x to left and y to right;

x = 4y - 8

Then solve for y;

y = (x + 8)/4 = x/4 + 2

Your y is the inverse of f(x) = 4x - 8

f^-1(x) = x/4 + 2
