Yes when the function f(x) = -2x3+17x2-64 is divided by x-8, the remainder is zero. Therefore, x-8 is a factor of f(x) = -2x3+17x2-64
Answer:
3rd option


Step-by-step explanation:
So we are given the following points:
(1,5)
(2,15)
(3,45)
(4,135)
This is a geometric sequence because there is a common ratio, 3. That is you can keep multiply 3 to a previous y-coordinate to get the next y-coordinate.
The formula for a geometric sequence is 
where
is the first term and r is the common ration.
So we have
.
If you want to know the fifth term, just plug in 5:

Simplifying:



Let
L---------> the length side of the box
W--------> the width side of the box
H-------> the height of the box
we know that

the surface area of the box is equal to

<u>Find the area of the base</u>

<u>Find the perimeter of the base</u>

<u>Find the surface area</u>


therefore
<u>the answer is</u>
the total area of the box that will be covered in gift wrap is 
She will need 12 seconds because -20•12=-240
