B and D are the only true statements.
<span>
A </span>function<span> is a relation for which each value from the set of the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair. Alternatively, you can think of this as for each x, there is one and only one y. Clearly that is not the case here, but it is the equation of the vertical line </span>x = 3.

Katen [24]

Answer:

The area of the wall that she will paint in two rolls is <u>219.8 inches²</u>.

Step-by-step explanation:

Given:

Jenny uses a roller to paint a wall. The roller has a radius of 1.75 inches and a height of 10 inches.

Now, to find the area of the wall that she will paint in two rolls.

So, we find the lateral surface area of roller.

Radius (r) = 1.75 inches.

Height (h) = 10 inches.

So, to get the lateral surface area we put formula:

A_{L} =2\pi rh

A_L=2\times 3.14\times 1.75\times 10

A_L=109.9\ inches^2.

Thus, the lateral surface area of the roller = 109.9 inches².

Now, to get the area of wall that she will paint in two rolls we multiply 2 by the lateral surface area of the roller:

109.9\times 2\\\\=219.8\ inches^2.

Therefore, the area of the wall that she will paint in two rolls is 219.8 inches².

A town has a population of 13000 and grows at 2.5% every year. What will be the population after 5 years, to the nearest whole n
vova2212 [387]

Answer:

The population will be 14708

Step-by-step explanation:

formula

A = P (1+r)^t

Initial population = P = 13000

Growth rate = r = 2.5% = 0.025

Number of years = t  = 5 years.

A = 13000 (1+.025)^5  = 14708

A rectangular swimming pool has an area of (70x+10) square feet. Find possible dimensions of the pool.
NNADVOKAT [17]

Answer:

10 and 7x + 1

Step-by-step explanation:

The area of a rectangle is 70x + 10.

Let's factor 70x + 10.

Factor out a common factor of 10.

70x + 10 = 10(7x + 1)

Since the area of a rectangle is length * width, we can let one factor be the length and the other factor be the width.

Possible dimensions are 10 and 7x + 1
