You are suppose to use a ruler to rotate the thing you need to rotate
Step-by-step explanation:
f(x) = x / (x - 7) = 1 + 7 / (x - 7).
The domain of f(x) depends whether the denominator of the rational expression is non-zero.
When (x - 7) = 0, x = 7.
Hence domain of f(x)
= All real values of x excluding 7. (C)
Part A:
1) 16
2) -25
3) 9
4) -7
I'm too lazy to do the rest, just pay attention in class next time
The amount earned from the local account must be greater than that of the online account.
Amount from local account = 6,500(1.0145)ⁿ
Amount from online account = 6,500(1.0225)ⁿ - 4x
Where n is the number of years and x is the number of ATM withdrawals.
6,500(1.0145)ⁿ > 6,500(1.0225)ⁿ - 4x
4x > 6,500[(1.0225)ⁿ - (1.0145)ⁿ]; n = 1
x > 13
The number of withdrawals must exceed 13.
The answer is C.
