Answer should be A, I hope this helps! Btw you shouldn't be asking about something thats on a test haha but thats fine! We all do it sometimes!
Answer:
A, D and E.
Step-by-step explanation:
We're going to examine the thousandth digit to answer this question.
In the case of A, the thousandth digit is 4, therefore we can round it down to zero, this results in 7.910 which is 7.91.
In the case of 7.905, we do the same with the digit 5, this will gives us 7.90.
For C, we can round down the digit 1 to zero, this will give us 7.90.
For D, we take the 5 and round it down to zero and this gives us 7.91.
For E, we take the 9 from the thousandths and we will round it up, therefore the .709 transforms into .710, this gives us 7.91.

Answer:
Option A -The curves intersect at approximately x = 0.46.
Hello from MrBillDoesMath!
Answer: 500
Discussion:
The idea is to represent p(x) with a squared component...
3 + 4x - 4x^2 =
3 - ( 4x^2 - 4x) =
Add and subtract 1:
(3+1) - (4x^2-4x +1) =
4 - (2x-1)^2
To maximize profit we need to minimize the term (2x-1)^2 as it is always positive (or zero) and subtracts from the number 4. The minimum of (2x -1)^2 occurs when 2x -1 = 0 or x = 1/2. Since x is the number of speakers in thousands, (1/2)x = 500 speakers.
Note: this problem can be more easily addressed in a Calculus course by taking the first derivative of p(x), setting it to zero, and solving for x (which yields x = 1/2 too)
Thank you,

Given:
In ΔNOP, n = 910 inches, o = 110 inches and p=820 inches.
To find:
The measure of ∠P to the nearest degree.
Solution:
According to the law of cosine:

Using law of cosine in triangle NOP, we get

Putting the given values, we get




Taking cos inverse on both sides, we get



Therefore, the measure of ∠P is 33°.
