Answer:
Step-by-step explanation:
Since the question implies a constant rate, we can set up the following proportion:
Well you do 62.80 times .06 for the 6% sales tax. Then put that in the calculator and you get 3.77 after you round. Then add the 3.77 to the 62.80 and you get $66.57
Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume.
So you have your polynomial. To factor this out, you need to find the factors of -45 that will add up to 3. These two factors would be -5 and 8. So, you have factored your polynomial! (x-5)(x+8). If you are still unsure, simply use the FOIL method to check and see if you get the same polynomial back. Hope this helps!
