Answer:
Approach: Difference of Squares Pattern

Step-by-step explanation:
The given binomial is:

We can rewrite to obtain:

This is a difference of two squares, so we will factor using difference of squares pattern.
Recall that:

If we let

and

Then we can factor the given binomial to obtain:


You have to multiply the length by the width and the sum of that you will multiply by the height. In this case 13.5 times 12 is 162. So 162 times 14.1 is 2284.2
Answer:
Step-by-step explanation:
Average rate of change is the same thing as the slope. Because this is parabolic, we cannot find the exact rate of change as we could if this were a linear function. But we can use the same idea. When t = 3, h(t) = 33, so the coordinate point is (3, 33). When t = 6, h(t) = 0, so the coordinate is (6, 0). Plug those values into the slope formula:
and
which is -11
From 3 to 6 seconds, the rocket is falling 11 yards per second.
Its already an improper fraction.
If you mean mixed number it would be 7 4/7.
Hope this helps!:)
Mu=80, sigma=39, X=85
Z=(X-mu)/sigma = 5/39=0.128=0.13
P(X<=85)= 0.5517 (from Z-table)
so, P(X>85)=1-0.5517=0.4483 approx. thats 44.8% probability.
