B
Substitute the first number for x and see which one it is
6 x 1 - 4 = 2
She walked .6 mph because 3/5 x 2= 6/10
1/2 x 2=1
Answer:
The answer is A
Step-by-step explanation:
In order for it to be a function every x value has to have a different y value or every input has to have a different output.
To best estimate the volume of the log, we assume that the diameter is the average of the diameters at both ends giving us 12 inches as the diameter. Thus, the radius is equal to 0.5 ft. The volume of the log is calculated through the equation,
V = πr²h = π(0.5 ft)²(10 ft) = 7.85 ft³
