Write a function in terms of t that represents the situation. Sales of $10,000 increase by 65% each year.
y =
13

A function in terms of t that represents the situation is:

Step-by-step explanation:

We know that the exponential growth function is of the form

Here:

As the sales of $10,000 represent an initial condition. Thus,  

a = 10,000

Given that sales are increased by 65% every year.

r = 65% = 0.65

now substituting a = 10,000 and r = 0.65 in the function

Therefore, a function in terms of t that represents the situation is:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
