Stacey has a part-time job at the bike shop. She saves $100 every four weeks for a new car. Find her rate of change After four weeks, she will have $ After 12 weeks , she will have $ per week Stacey's rate of change is $

She will have $25 per week Stacey's rate of change is $25.

She will have $300 After 12 weeks.

Step-by-step explanation:

Given : Stacey has a part-time job at the bike shop. She saves $100 every four weeks for a new car.

To find : Her rate of change After four weeks, she will have $ After 12 weeks , she will have $ per week Stacey's rate of change is $ ?

Solution :

In every four weeks she saves $100.

In every one week she save .

In every one week she save $25.

After 12 week she save .

After 12 week she save $300.

The rate of change is

She will have $25 per week Stacey's rate of change is $25.

She will have $300 After 12 weeks.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
