Answer:
Step-by-step explanation:
Given
Let the roots be and
So:
Required
Determine the relationship between d, c and p
Divide through by d
A quadratic equation has the form:
So:
So, we have:
-- (1)
and
-- (2)
Make the subject in (1)
Substitute in (2)
Multiply both sides by d
Cross Multiply
or
Hence, the relationship between d, c and p is:
Basically, we have to find out what 72% of 92 minutes is. A way to do this is turn 92 minutes into a decimal: 92 / 100 = 0.92 and then multiply the decimal by 72: 0.92 x 72 = 66.24 minutes. Rounding to the nearest tenth, however, changes the number to 66.2 minutes. Hope this helps!
