ANSWER 1
Note that,
is the same as
We apply the product rule.
So we keep the second function and differentiate the first,plus we keep the first function and differentiate the second.
Recall that,
If
Then,
This implies that,
ANSWER 2
We apply the product rule and the chain rules of differentiation here.
Recall that,
If
Then,
This implies that,
Thus the third option is the correct answer.
Answer: The slope is 1/8
Step-by-step explanation:
Full equation = ( y = 1/8x-1/8)
Answer:
1). 
2). 0.81
3). 81%
Step-by-step explanation:
There are total 10×10 = 100 squares in the picture and number of shaded squares = 100 - 19 = 81
Shaded area expressed as the fraction of the whole =
Shaded area in decimals of the whole = 
Shaded area in percent of the whole = 
= 81%
Answer:
A. must be proportional because the points lie in a straight line
