Answer: Y= 67
Step-by-step explanation:
The equation says;
Y= 15x + 7
When x=4
We have Y= 15(4)+7 by substituting the value of x for the equation. So, we have
Y=60+7
Y= 67
If the moving object is undergoing constant acceleration, then

(take the average of the initial and final velocities, if they're given)
If you don't know the acceleration or initial/final velocities, then you have to resort to the usual definition,

where
is the change in position and
is the duration of the interval.
Answer:
The cost in 2015 will be $283.45.
What is the reference point (t=0)?
d. The year 2005.
Step-by-step explanation:
The exponential growth model for the cost is the following:

In which C(t) is the cost after t years,
is the initial cost and r is the decimal inflation rate
In this problem, we have that:

What will it cost in 2015 assuming the rate of inflation remains constant?
2015 is 10 years after 2005, so this is C(10).


The cost in 2015 will be $283.45.
The reference point is the year in which t = 0, so the year 2005.
