Answer:
Both are linear functions.
Step-by-step explanation:
There are no same x values in the table and the graph passes the vertical line test.
It should be 7 wouldnt it be
The independent variable here is b, the number of mats; the dependent var. is p, the cost of b mats. Thus, p = f(b).
Here, 245 units^3 = pi*r^2*(5 units), or
245 units^3
r^2 = ------------------- = 15.61 units^2. Thus, the radius is sqrt(15.61 units^2), or
5(3.14) units 3.95 units. The DIAMETER is d = 2*r = 7.90 units.
A) =27.2
b) = 30.1
c) =31.2
d) =36.6
answer = D
