Answer:

x^2+14x+49 ( it could be polynomial because it has 3 terms and each term has a whole number and a coefficient)

Step-by-step explanation:

(x+7)^2

(x+7)(x+7)

x^2+7x+7x+49

x^2+14x+49

I am not sure it's a polynomial or not

Your company maintains a cylindrical oil refinery storage tank that is 190 feet across on the inside and 80 feet high. The tank

Lorico [155]

Answer:

The correct answer is A. You multiplied that tank's radius by two instead of calculating r²

Step-by-step explanation:

This is the wrong calculation we did:

Volume of the cylindrical oil refinery storage tank = π * 2r * h * 0.75

Replacing with the real values, we got:

Volume of the cylindrical oil refinery storage tank = 3.14 * 2 * 95 *80 * 0.75

Volume of the cylindrical oil refinery storage tank = 35,796 cubic feet (Rounded 35,800)

This is the correct calculation we should have done:

Volume of the cylindrical oil refinery storage tank = π * r² * h * 0.75

Replacing with the real values, we got:

Volume of the cylindrical oil refinery storage tank = 3.14 * 95² *80 * 0.75

Volume of the cylindrical oil refinery storage tank = 1'700.310 cubic feet

What is the perimeter of this figure, to the nearest unit?

lana66690 [7]

Answer:

P=38

Step-by-step explanation:

At this case I would use the circumference formula for the rounded part.

The formula of the circumference is C=2πr.

So... We know that the radius is 5 which is half of the diameter. So... C=2π5 which is C=10π or C=31.4 which we divide by 4 because on the image is 1/4th of a circle and C/4 which C=7.85 so the P of the whole figure is P=10+10+5+5+7.85 which is P=37.85 which will be P=38.

Answer: P=38
