Answer:

770 cubic inches (769.69)

Step-by-step explanation:

V = π $r^{2}$ h

r = d/2 = 14/2 = 7 inches

h = 5 inches

V = π * $7^{2}$ * 5 ≈ 769.69 ≈ 770 cubic inches

Write an equation of the line that passes through (2,7) and is parallel to the line shown ( please help !! )

Anna007 [38]

Answer:

$y=2x+3$

Step-by-step explanation:

We will first need to determine the slope of the line shown.

We know that it passes through the two points (-2, -2) and (1, 4).

Thus, we can use the slope formula to find the slope between the two points:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Let (-2, -2) be (x₁, y₁) and let (1, 4) be (x₂, y₂). Substitute:

$\displaystyle m=\frac{4-(-2)}{1-(-2)}=\frac{6}{3}=2$

Hence, the slope of the original line was 2.

Since we want the new line to be parallel, the slope of the new line must also be 2.

We know that the slope is 2 and it passes through the point (2, 7).

So, we can use the point-slope form:

$y-y_1=m(x-x_1)$

We will substitute 2 for m. We will also let (2, 7) be (x₁, y₁). Substitute:

$y-7=2(x-2)$

Solve for y. Distribute the right:

$y-7=2x-4$

Add 7 to both sides. Hence, our equation is:

$y=2x+3$

Each story of a building is 14.3 feet tall. If the height of the building is 185.9 feet, how many floors does the building have?

zvonat [6]

Answer:

D 13

Step-by-step explanation:

To find out how many floors the building has, we take the height of the building and divide by the size of each floor

floors = 185.9 ft / 14.3ft per floor

= 13 floors

The number of bacteria in a culture is expected to grow 82% per hour over the next several hours. The predicted change in the nu

Advocard [28]

If my simplification is valid the answer is:

1.4 % growth each minute

I don’t feel like the representation
P = 120(1.82) is important in this certain problem.

So P the predicted number of bacteria is not practical with this problem.

Use the 82% per hour and divide it by 60 because there are 60 minutes in an hour.

When doing this you find the rate in which bacteria grows which is about 1.4%.

The prediction is about 1.82 percent for 120 something it’s not clarified, but I’m guessing that’s minutes.

So you can prove that the prediction is over the rate in which bacteria grows per minute.
