F(5) = 21
look on the table and find where x=5 on the top row, the number that is with it is 21
f(x) = 7
x=6
look on the table and find where f(x)=7 on the bottom row, the number with it is 6
Answer:
decreases as the required rate of return increases.
Step-by-step explanation:
Net present value (NPV) is the difference between the present value of cash inflows and the present value of cash outflows over a period of time. This differences tend to reduce as the requires rate of return increases.
It says that you need to divide 2 exponents with the same base, you keep the base and subtract the powers, its kind of like reducing fractions! :)
The answer is x = 5. Hope that helps, God bless!
Answer:
A, B, C and D. are solutions.
Step-by-step explanation:
x^2 + y^2 = 13
x^2 - y^2 = 5
Check which roots fit the original equations:
If x = 3, A gives
9 + y^2 = 13 giving y = +/- √4 = 2 or -2.
Now plug in x = 3 and y = 2 in the second equation:
9 - (2)^2 = 5
Therefore (3,2) is a solution of the 2 equations.
Following the same procedure for B, C and D:
B. Substituting x = 3 and x = -2 fits both equations so (3, -2) is a solution.
The same is true for C and D.
