Answer and Step-by-step explanation:
To solve, we would multiply by the reciprocal of the portion Jada has read, and multiply that number to 75.
The reciprocal means the the value, but flipped, so will become .
Now we do 75 times /
So, there are 125 total pages in the book.

You can actually use either the product rule or the chain rule for this one. Observe:
• Method I:y = cos² xy = cos x · cos xDifferentiate it by applying the product rule:
The derivative of
cos x is
– sin x. So you have
—————
• Method II:You can also treat
y as a composite function:
and then, differentiate
y by applying the chain rule:
For that first derivative with respect to
u, just use the power rule, then you have
and then you get the same answer:
I hope this helps. =)
