The hourly growth rate of bacteria is 191.25
<u>Solution:</u>
Given that, initially Shelly put 85 bacteria and waits 4 hours
Amount of bacteria after 4 hours = 850
Now, number of bacteria increased = 850 bacteria – initial 85 bacteria
Number of increased bacteria = 850 – 85 = 765 bacteria.
So, 765 bacteria were produced in 4 hours.
So hourly growth rate( per hour) can be found out by as follows:


Hence, the hourly growth rate of bacteria is 191.25
ANSWER
b. 32
EXPLANATION
The give expression is:

We want to find the remainnder when this polynomial is divided by x-3 using synthetic division.
We write out the coefficient and perform the synthetic division as shown in the attachment.
The remainder is 32
4a+7b-12c-8a-9b+12d
Now you have to combine like terms, so a and a, B and B etc.
4a-8a=-4a
7b-9b=-2b
No more like term
-4a-2b-12c+12d
