Given:
Principal value = $640
Rate of interest = 3.9% not compounded
Number of years = 8
To find:
The amount after 8 years.
Solution:
It is given that the interest is not compounded. It means, we need to find simple interest.
Formula for simple interest:
where, P is principal, r is rate of interest and t is time in years.
Put P=640, r=0.039 and t=8.
So, the interest is $199.68.
Now, amount after 8 years is
where, P is principal and I is interest.
Therefore, the amount after 8 years is $839.68.
Answer:
.
Step-by-step explanation:
The equation that represents the function can be written in the slope-intercept form, .
To create an equation, we need to find the slope (m) and the y-intercept (b) of the function.
First, calculate the slope of the function using two points, (1, 12) and (2, 19).
Next, find b by substituting x = 1, f(x) = 12, and m = 7 into .
Subtract 7 from each side
Substitute m = 7 and b = 5 into .
✅Thus, the equation that represents the function would be:
.
