Answer:
d=1
Step-by-step explanation:
Answer:
Area of shaded region=41 square feet
Area of non shaded region= 87 square feet
Step-by-step explanation:
As, Shaded area is made of different shapes including two rectangles and one triangle
So,
Area of shaded region,
![=(8\times2)+(10\times 1)+(\frac{1}{2}\times 3\times10)\\\\ =16+10+15=41 \quad \text{square feet}](https://tex.z-dn.net/?f=%3D%288%5Ctimes2%29%2B%2810%5Ctimes%201%29%2B%28%5Cfrac%7B1%7D%7B2%7D%5Ctimes%203%5Ctimes10%29%5C%5C%5C%5C%20%3D16%2B10%2B15%3D41%20%5Cquad%20%5Ctext%7Bsquare%20feet%7D)
Area of non shaded region=total area of rectangular region-Shaded region

Answer:
![8.182X10^8 $pounds](https://tex.z-dn.net/?f=8.182X10%5E8%20%24pounds)
a=8.182 and b=8
Step-by-step explanation:
Weight of the Empire State Building =
pounds.
Weight of the One World Trade Center building= 88,200,000 pounds.
=![8.82 X 10^7](https://tex.z-dn.net/?f=8.82%20X%2010%5E7)
The addition of the two:
![=7.3X 10^8+8.82 X 10^7\\$To make it easier to add, express both as powers of 8\\=7.3X 10^8+0.882 X 10^8\\=(7.3+0.882)X10^8\\=8.182X10^8 $ pounds](https://tex.z-dn.net/?f=%3D7.3X%2010%5E8%2B8.82%20X%2010%5E7%5C%5C%24To%20make%20it%20easier%20to%20add%2C%20express%20both%20as%20powers%20of%208%5C%5C%3D7.3X%2010%5E8%2B0.882%20X%2010%5E8%5C%5C%3D%287.3%2B0.882%29X10%5E8%5C%5C%3D8.182X10%5E8%20%24%20pounds)
Comparing with the form: ![aX10^b](https://tex.z-dn.net/?f=aX10%5Eb)
a=8.182 and b=8
Simply the answer is -x^2-x+6 but not sure if you want to factor it but it would be (x-2)(x+3) and not sure how to do the domain
