bogdanovich [222]

Answer:

Yes, the farmer have enough paint to complete the job.

Step-by-step explanation:

It is given that a gas storage tank is in the shape of a right circular cylinder.

The radius of the base is 2 ft and the height of cylinder is 3 ft.

The total surface area of a cylinder is

$S=2\pi rh+2\pi r^2$

Total surface area of gas storage tank is

$S=2\pi (2)(3)+2\pi (2)^2$

$S=12\pi+8\pi$

$S=20\pi$

$S=62.8318530718$

$S\approx 62.83$

The total surface area of gas storage tank is 62.83 square feet.

The farmer has 1 gallon of paint and 1 gallon of paint will cover 162 square feet.

Since 62.83<162, therefore 1 gallon of paint is enough to paint the gas storage.

Hence the required statement is Yes, the farmer have enough paint to complete the job.

Consider the line y=-5/4x-5 find the equation of the line that is parallel to this line and passes through the point (-8,4)

gayaneshka [121]

Answer:

y = -5/4x + 6

Step-by-step explanation:

Since the line we are supposed to find is parallel to y = -5/4x - 5 that means they are going to have the same slope. The line we are looking for is of the following type: y = -5/4 x + b

Since it passes through the point (-8,4):

4 = -5/4 * (-8) + b <=>

4 = -2 + b <=>

4 + 2 = b <=>

b = 6

Hence the line is going to be: y = -5/4x + 6
