Hi there
We know that the formula of the present value of annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value
PMT monthly payment
R interest rate
K compounded monthly 12 because the payment is monthly
N time
What we need from the formula above to find the monthly payment
So to find the monthly payment the formula
PMT=pv÷[(1-(1+r/k)^(-kn))÷(r/k)]
Another important things we need is how to find total payments and interest charge
To find total payments
Monthly payment×12
And to find interest charge
Total payments-present value
Now let's find interest charge for each credit card
Credit card A
The monthly payment is
PMT=563÷((1−(1+0.16÷12)^(
−12))÷(0.16÷12))=51.08
Total payments
51.08×12=612.96
interest charge
612.96−563=49.96
Credit card b
PMT=2,525÷((1−(1+0.21÷12)^(
−12))÷(0.21÷12))=235.11
Total payments
235.11×12=2,821.32
interest charge
2,821.32−2,525=296.32
Credit card c
PMT=972÷((1−(1+0.19÷12)^(
−12))÷(0.19÷12))=89.58
Total payments
89.58×12=1,074.96
interest charge
1,074.96−972=102.96
So total interest charge for all credit cards is
102.96+296.32+49.96
=449.24....final answer
It's c
Good luck!
Answer:
Rise over Run
Step-by-step explanation:
You need to find the rise over run. Find a point where the line crosses a set of points on the graph. Then find another point on the graph where the line crosses. start at the bottom point and count up till you get even to where the point is. then count over till you get to the point. That is your rise over run. Now simplify the rise over run. You should get a number and that is how you can tell if if a lines slope is equal to 1, greater than 1, or less than 1.
Hope this Helps!
A line tangent to a circle is always perpendicular to the radius or the diameter to the circle. Since angle x has been formed by the intersection of the tangent line and the diameter of the circle the we can conclude that the the angle formed is:
x°=90°
Answer: A] 90°
