Answer:
2/3
Step-by-step explanation:
Y varies directly as x
Y =kx
Y=6 when x = 72
First find the relationship between y and x.
i.e find the value of k
Substitute the value of x and y
6 = k *72
Make k the subject of the formula
K = 6/72
K= 1/12
:. The rlationship between x and y is
Y = 1/12x
When x is 8
Y = 1/12 * 8
Y = 8/12
Y = 2/3 and that is the answer

Since he completes 10 minutes each day for five days, he completes 50 minutes.
The percentage of his total requirement would be 50/100 = 0.5 = 50%.
H'(x) = 2f'(x)
h'(1) = 2*f'(1) = 2*4
h'(1) = 8
