Answer:

C.  For each bolt the number of cracks decreased by an average of 1/2.

Step-by-step explanation:

Consider the points (2, 8) and (8, 5) on the line.

The number of cracks decreased from 8 to 5 while the number of bolts increased from  2 to 8. Thats a ratio of -3 : 6, which supports choice C.

What is the area of the region bounded by the lines x= 1 and y= 0 and the curve y=xe^x^2?
Mice21 [21]

Answer:

A = 0.859

Step-by-step explanation:

We want to find the area of the region bounded by the lines x = 1 and y = 0 and the curve y = xe^(x²).

At y = 0, let's find x;

0 = xe^(x²)

Solving this leads to no solution because x is infinity. Thus we can say lower bound is x = 0.

So our upper band is x = 1

Thus,lets find the area;

A = ∫xe(x²) dx between 1 and 0

A = (e^(x²))/2 between 1 and 0

A = ((e¹)/2) - (e^(0))/2)

A = 1.359 - 0.5

A = 0.859
