Answer:
A - y = 1200(1+.05)^30
Step-by-step explanation:
In this case, you need to calculate the future value and the formula to calculate that is:
FV=PV*(1+r)^n
FV=future value
PV=present value
r=rate
n=number of periods of time
The present value would be the price of the ring which is $1200. The rate is 5% per year and the number of periods of time is 30 years since you need to find the ring's worth in 30 years. Now, you can replace the values on the formula:
FV=1200*(1+0.05)^30
According to this, the answer is that the equation to calculate how much will it be worth in 30 years is: y = 1200(1+.05)^30.
Let the measure of the angle be x and from that the measure of its complement is 90 - x. The equation that best represent the given condition above is,
3x = (90 - x) - 14
The value of x from the equation above is 19. Thus, the answer is letter A.
We can write the function in slope-intercept form (y + mx + b). Since we have the slope, we can solve for the y-intercept.
y = -2x + b
4 = -2(0) + b
4 = b
Input the data we have now.
y = -2x + 4
Since we are dealing with a function switch out the y for f(x)
f(x) = -2x + 4
Best of Luck!
