PLEASE HELP ME WILL MARK ANSWER BRAINLIEST!

6. A circular swimming pool has a diameter of 24 ft. and a water height of 3.5 ft. A pump can fill the pool at a rate of 1.2 ft cubed (9 gallons) per minute. About how long it will take to fill this pool ( in hours)?

A. About 15 hours

B. About 1300 hours

C. About 88 hours

D. About 22 hours

C. About 88 hours. The area of a circle is π(r)^2 which equals 1,809.56ft^2(substitute r with 24). You multiply that by 3.5 because the height is 3.5 and you get 6,333.46ft^3. You divide that by 1.2 and get 5,277.88, which is how many minutes it would take the pool to fill. You then divide by 60 because there are 60 minutes per hour and you get 87.9≈88. It would take 88 hours to fill this pool

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!

Hello!

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

why?

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
