When you have a power to a fraction, you simply take it by the top and then by the bottm.
So, split it into two: (2)^4 and (5)^4
Solve: (2)^4=16
(5)^4=625
So the fraction is: 16/625
Check to see if it reduces: It doesn't. (Odd and even numbers that have no common multiples).
Therefore, that's the answer.
Answer:b
Step-by-step explanation:

We can solve
this problem by first calculating the annual net cash inflow. This can be
solved by remembering that:
Payback period
= Initial investment<span> / Annual net
cash inflow</span>
<span>
6 years = $75,000
/ Annual net
cash inflow
<span>
Therefore,
Annual net
cash inflow = $12,500
Next, we
calculate for the cost. The cost we will consider here is the depreciation
value of the machine.
Annual depreciation
= $75,000 / 15 years = $5,000
Therefore the annual net operating income is:
Annual net operating income = $12,500 - $5,000 = $7,500
Simple rate of
return is calculated by:
Simple rate of
return = Annual net operating income / Initial
investment
Simple rate of
return = $7,500 / <span>
$75,000 = 0.1 = 10%</span></span></span>
Answer:
C) x ≥ 11 or x ≤ -3
Explanation:
Given following: |x − 4| ≥ 7
Apply absolute rule: If |u| ≥ 0 then u ≤ -a, u ≥ a
Solving stepwise:
⇒ x - 4 ≤ -7, x - 4 ≥ 7
<u>change sides</u>
⇒ x ≤ -7 + 4, x ≥ 7 + 4
<u>add/subtract integers</u>
⇒ x ≤ -3, x ≥ 11
