Answer:

y = 2x + 0

Step-by-step explanation:

the formula is y = mx + b

m = slope = change in y/change in x = (84 - 76)/(42 - 38) = 2

Slope is 2.

b is the y-intercept, which is the coordinate when x = 0. To find b, substitute any coordinate from the table. Let's use (38, 76)

y = 2x + b

76 = 2(38) + b

76 = 76 + b

b = 0

So the equation is y = 2x + 0

A company rents water tanks shaped like a cylinders. Each tank has a diameter of 12 feet and a height of 3 feet. The cost is $2

12345 [234]

Answer:

$\$678.58$

Step-by-step explanation:

step 1

<u>Find the volume of the tank</u>

we know that

The volume of a cylinder (water tank) is equal to

$V=\pi r^{2}h$

in this problem we have

$r=12/2=6\ ft$ -----> the radius is half the diameter

$h=3\ ft$

substitute

$V=\pi (6^{2})(3)=339.29\ ft^{3}$

step 2

Find the cost

$339.29\ ft^{3}*2\frac{\$}{ft^{3}}=\$678.58$

Valentin [98]

your answer is 30

1^2 (raised to the power of 2) +2 is 3

5^2 +2 is 27

5^2=25

1^2=1

Help please :))) thank u

Gnom [1K]

Answer:

The distance between A and B is 8.5 after rounded to the nearest tenth

Step-by-step explanation:

The formula you always use for distance between points is as pictured.

Point A is (-6, 4), this is x1 and y1

Point B is (2, 1), this is x2 and y2

(2-[-6])^2 + (1-4)^2

since 2 negatives make a positive, 2 - -6 = 8

1 - 4 = -3

This makes 8 squared and -3 squared

8x8 = 64

-3x-3 = 9

64 + 9 = 73

the square root of 73 = 8.544003745

After rounding to the nearest tenth, it is 8.5

I hope this helps you! Good luck :)
