For 12 months, jeanne has belonged to a book-of-the-month club. jeanne has spent $70.45 on the club. the first month, she paid the monthly fee and spent an additional $10.45 on books. she has only paid the monthly fee since then. what are the initial value and the rate of change of this function?

The initial value is $10.45

The rate of change is  

Step-by-step explanation:

Let

m-----> the the monthly fee  

we know that

Solve for m

Find the linear equation that represent this problem

Let

x -----> the number of months

y-----> amount Jeanne has spent monthly

The equation in slope intercept form is equal to

where

m is the slope (the monthly fee)

so

Remember that

The first month, she paid the monthly fee and spent an additional $10.45

For x=1, y=5+10.45=15.45

substitute

The equation is

therefore

The initial value is $10.45

The rate of change is the slope of the linear function

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

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
