Step-by-step explanation:
Consider the polynomials given below.
P(x) = 14 + 3.13 + 2x2 - + 2
Q*) = (x3 + 2x2 + 3)(x2 - 2)
Determine the operation that results in the simplified expression below.
25 + 14 - 513 - 312 + I-8
A. P+Q
B. P.Q
C. PQ
D. O-P
The operation that results in the simplified expression x⁵ + x⁴ - 5x³ - 3x² + x - 8 is; P + Q
How to Simplify Polynomials?
We are given the Polynomials as;
P(x) = x⁴ + 3x³ + 2x² - x + 2
Q(x) = (x³ + 2x² + 3)(x² - 2)
We want to find the combination of P and Q that would yield;
x⁵ + x⁴ - 5x³ - 3x² + x - 8
Let us expand Q(x) to get;
Q(x) = x⁵ + 2x⁴ + 3x² - 2x³ - 4x² - 6
Q(x) = x⁵ + 2x⁴ - 2x³ - x² - 6
Now, the combined polynomial shows us that coefficient of x⁴ is 1 and coefficient of x³ is - 5.
By inspection, we can say that the combination that would produce the required result is;
Q(x) - P(x) = x⁵ + 2x⁴ - 2x³ - x² - 6 - x⁴ - 3x³ - 2x² + x - 2
Q(x) - P(x) = x⁵ + x⁴ - 5x³ - 3x² + x - 8

Sami cut 6 and three fourth inches off a long roll of paper if the row 36 and one third inches long how long was the original roll of papers
Answer:
43 1 ÷12
Step-by-step explanation:
The computation of the length of the original roll of papers is shown below:
36 1 ÷3 and 6 3 ÷ 4 together
Now convert the above fractions into a number
36 1 ÷ 3 = 109 ÷3
And,
6 3 ÷4 = 27 ÷ 4
Now add these two numbers i.e.
109 ÷3 + 27 ÷ 4
= 436 + 81 ÷ 12
= 517 ÷12
= 43 1 ÷12

A window in the shape of a semi circle has a radius of 40 cm. The window is shown below. Find the area of the window.
Answer:
[tex]A=2513.27\ cm^2[/tex]
Step-by-step explanation:
The radius of semicircle window, r = 40 cm
The area of semicircle is given by :
[tex]A=\dfrac{\pi r^2}{2}[/tex]
Substitute all the values in the above formula.
[tex]A=\dfrac{\pi \times 40^2}{2}\\\\A=2513.27\ cm^2[/tex]
So, the area of the window is equal to [tex]2513.27\ cm^2[/tex].

We want to find which model shows two equal expressions. We know that the value of x is 6. That being said, on the left side of each equation, plug in 6 for every "x" you see. Then, add the values on both sides. If they're equal, that's your answer.
For example:
In choice A, we see two x's, so we plug in 6 for them both and add them. That's 12 on the left side. On the other side of the equation, we have 7 "1" boxes, which simply just means add them, so that's 7 on the other side. 12 does not equal 7, therefore A is not the answer. However, for choice C, we are given x, which we know is 6, and a "1" box, which simply means 6 + 1, which is 7. On the other side of this equation, we have 7 "1" boxes, so that's 7. The equation becomes 7 = 7, which is true, so that is our answer.

An endocrinologist is interested in the effects of depression on the thyroid. It is believed that healthy subjects have a mean thyroxin (a hormone related to thyroid function) level of 7.0 micrograms/100 ml and a standard deviation of 1.6 micrograms/100 ml. The endocrinologist wants to assess whether the mean thyroxin level is different for those with depression. She samples 35 subjects with depression and obtains a sample mean of 7.82 micrograms/100 ml for thyroxin. What null and alternative hypotheses should she test
Answer:
H0: μ = 7.0
H1: μ > 7.0
Step-by-step explanation:
The null hypothesis will equal and take up the value of the population mean value ;
The population mean value, μ is 7.0
Null hypothesis ; H0: μ = 7.0
The alternative hypothesis will align with the claim ; which will take up and side with the value and direction of the sample mean ; 7.82 micrograms/100 ml
7.82 > 7.0 (sample mean is greater Than the population mean).
Hence, the alternative hypothesis, H1 will be ;
H1 : μ > 7.0
