Answer:
Option C is the correct answer.
C. 5•(-20)
Step-by-step explanation:
We are told that the insurance payment for the car follows a certain pattern that can be represented through an expression. The payment is decreasing by $20 every year. As we don't know the total payment amount per period, so we cannot calculate how much is paid per period/year for insurance but we can calculate the rate at which this payment is decreasing.
Change in payment = t * (-20)
The above expressions can be used to calculate the amount of change in payment i payment is decreasing by a constant $20 every year, after t years.
So, if we want to calculate the change in payment after say 5 years, we can replace t with 5 in the equation and calculate the change,
Change in payment = 5 * (-20)
Change in payment = - $100
Answer:
400
Step-by-step explanation:
You would multiply 40 by 10=400
Answer:
multiply 5*8 and you will get the answer... 40cm
Given:
The graph of an invertible function 
<em> </em>is given.
To find:
The value of 
.
Solution:
We know that, if the graph of an invertible function passes through the point (a,b), then the inverse function 
passes through the point (b,a).
From the given graph it is clear that the graph of the function passes through the points 
.
So, the inverse function must be passes through the point 
.
Therefore, the value of inverse function is 
at 
. So, the value of is .
