The driveway of the Santiagos' new home is to be bounded by semicircle arcs as shown. The distance from X to Y is 100 ft. The concrete driveway is 10 ft wide and 1/3 fit thick. Using 3.14 as an approximation for pi, how many cubic feet of concrete are needed to build the driveway? (Round your answer to the nearest cubic foot.) A. 471 ft^3
B. 942 ft^3
C. 1060ft^3
D. 1308 ft^3
E. 1884 ft^3

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

if you divide 9 by 6 you will get 54.
