<h3>
Answer: Choice C</h3>
================================================
Explanation:
If all the exponents are even, then the polynomial function is even.
- Choice A has a mix of even and odd exponents here, so choice A is neither even nor odd. We can rule this out.
- Choice B is the same story as choice A. So we can rule that out as well.
- Choice C has all of its exponents even. Therefore function C is an even function, and it's the final answer.
- Choice D is the same story as choice A. The only difference is the leading coefficient is positive.
Answer:
Step-by-step explanation:
Refer to physics equation , where is angular velocity.
Angular velocity's SI unit is rad/s. Convert rev/min to rad/s:
Now substitute and into :
Here’s how you can set up the problem:
10 + 25d = 40 + 10d
(d means pages per days)
15d = 30
D = 2
So, the answer would be two days. You can check this by plugging it into the problem:
10 + 25(2) = 40 + 10(2)
10 + 50 = 40 + 20
60 = 60; correct!
Hope this helped! :)
