Compute the derivative of <em>y</em> = (<em>x</em>² + <em>x</em> - 2)² using the chain rule:
d<em>y</em>/d<em>x</em> = 2 (<em>x</em>² + <em>x</em> - 2) d/d<em>x</em> [<em>x</em>² + <em>x</em> - 2]
d<em>y</em>/d<em>x</em> = 2 (<em>x</em>² + <em>x</em> - 2) (2<em>x</em> + 1)
Evaluate the derivative at <em>x</em> = -1 :
d<em>y</em>/d<em>x</em> (-1) = 2 ((-1)² + (-1) - 2) (2 (-1) + 1) = 4
This is the slope of the tangent line to the function at (-1, 4).
Use the point-slope formula to get the equation for the tangent line:
<em>y</em> - 4 = 4 (<em>x</em> - (-1)) → <em>y</em> = 4<em>x</em> + 8

Answer:
mean = 250.2
mean = 249.4
Step-by-step explanation:
given data
experiment = 15 times
solution
we get here mean that is express as
mean = 
............1
so mean for cart 1 is
mean = 
mean = 250.2
and
mean for cart 2
mean = 
mean = 249.4
Answer:
C
Step-by-step explanation:
The diameter is about three times smaller than the circumference. So by trial and improvement, we can see that 24.5 would be the correct answer.

Answer:
The average weight of three apples = 118 g
Estimated average weight of 36 apples = 1416 g or 1 kg 416 g
Total weight of 36 apples = 50976 g or 50 kg 976 g
