Find C and a so that f(x)equalsCa Superscript x models the situation described. State what the variable x represents in your formula. There are initially 3000 bacteria, and this sample doubles in size every hour.

x represents the time period.

C= 3000 and a = 2

Step-by-step explanation:

The given equation is which is an exponential equation. (i)

The general form of the exponential equation is :

  (ii)

, where A = initial value and b= multiplicative factor, and x is the time.

As compare both of the equation in (i) and (ii) , we get

A= C , and b= a

Since there are initially 3000 bacteria, and this sample doubles in size every hour.

i.e. C= 3000 (Initial)  and a= 2 (multiplicative factor).

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
