Answer:
The new expression is [tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex].
Step-by-step explanation:
A polynomial is a sum of algebraic monomials such that:
[tex]p = \Sigma_{i=0}^{n} c_{i}\cdot x^{i}[/tex]
Where [tex]n[/tex] is the degree of the polynomial and [tex]c_{i}[/tex] is the i-th coefficient of the polynomial. A 22nd degree polynomial has [tex]n = 22[/tex], so that given polynomial must added by a monomial with grade 22. Thus:
If [tex]p = 5\cdot x^{2} + 11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}[/tex] and [tex]q = 12\cdot x^{22}[/tex], then we have:
[tex]p' = p+q[/tex]
[tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex]
The new expression is [tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex].

Cassandra rents a bicycle while on vacation.
The table below shows the cost of renting a bicycle y, per hour, x.
What is the slope (m) that is defined by the table?
Explain using 2-3 sentences or show each step.
Answer:
m = 6
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply choose 2 points and plug them into the formula to find slope m:
(1, 20)
(2, 26)
[tex]m=\frac{26-20}{2-1}[/tex]
[tex]m=\frac{6}{1}[/tex]
m = 6

Find the midpoint of the segment with the given endpoints.
(-10,10) and (-9,6)
Answer:
The answer is
[tex]( - \frac{19}{2} \: , \: 2)[/tex]Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-10,10) and (-9,6)
The midpoint is
[tex]M = ( \frac{ - 10 - 9}{2} , \: \frac{10 - 6}{2} ) \\ = ( - \frac{19}{2} \: , \: \frac{4}{2} )[/tex]We have the final answer as
[tex]( - \frac{19}{2} \: , \: 2)[/tex]Hope this helps you

What is an exact solution for
[tex]m \sqrt{14} [/tex]
Answer: Choice B) [tex]\sqrt{14}[/tex]
We have some value m and we're squaring it to get [tex]m^2[/tex]
To undo this and isolate m, we apply the square root to both sides
[tex]m^2 = 14\\\\\sqrt{m^2} = \sqrt{14}\\\\|m| = \sqrt{14}\\\\m = \sqrt{14} \text{ or } m = -\sqrt{14}[/tex]
There are two solutions here. This is similar to how there are two solutions in something like [tex]x^2 = 25[/tex] (those two solutions being x = 5 and x = -5). Squaring any negative number leads to a positive result because
negative times negative = positive.

Answer:
7g is correct answer
Step-by-step explanation:
4g+6g-3g
=10g-3g
=7g
hope it helped you:)
Answer:4g + 6g - 3g = 7g
Step-by-step explanation:because 4+6 is 10 so 3 less than 10 it equals 7
(8w)^2 without parentheses
Answer:
I believe the answer would be 64w2.
Step-by-step explanation:
8 squared is 8 x 8, which equals 64, and then w squared is just w2, since we don't know what it is. Put them together, and the answer is 64w2.

The sum of three numbers is 12. The second number is equal to the sum of the first and third numbers. Twice the first number exceeds the second number by 4. Find the numbers.
Answer:
the first number is 5 the first second is 6 the first number is 1Step-by-step explanation:
x - first number
2x - twice the first number
twice the first number exceeds the second number by 4 so:
2x-4 -the second number
y - the third number
the second number is equal to the sum of the first and third numbers:
2x-4 = x + y
x + y = 2x - 4
-x -x
y = x - 4 - the third number
the sum of three numbers:
x + 2x-4 + x-4 = 4x - 8
The sum of three numbers is 12 so:
4x - 8 = 12
+8 +8
4x = 20
÷4 ÷4
x = 5
2x-4 = 2•5 - 4 = 6
x-4 = 5 - 4 = 1
Check:
5+1 = 6
2•5 = 10, 10-4 = 6
3 - 4x = 6x + 93
Please help with this question
Answer:
-9
Step-by-step explanation:
X=-9
Step-by-step
Simplifying
3 + -4x = 6x + 93
Reorder the terms:
3 + -4x = 93 + 6x
Solving
3 + -4x = 93 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
3 + -4x + -6x = 93 + 6x + -6x
Combine like terms: -4x + -6x = -10x
3 + -10x = 93 + 6x + -6x
Combine like terms: 6x + -6x = 0
3 + -10x = 93 + 0
3 + -10x = 93
Add '-3' to each side of the equation.
3 + -3 + -10x = 93 + -3
Combine like terms: 3 + -3 = 0
0 + -10x = 93 + -3
-10x = 93 + -3
Combine like terms: 93 + -3 = 90
-10x = 90
Divide each side by '-10'.
x = -9
Simplifying
x = -9

Select the correct answer. When Matt rewrote the given expression, he got 18. (36) 1/2 Which statement is correct? Matt rewrote the expression incorrectly. The expression is equivalent to 6. Matt rewrote the expression incorrectly. The expression is equivalent to 9. Matt rewrote the expression correctly. Matt rewrote the expression incorrectly. The expression is equivalent to 1/18
Answer: Choice A) He wrote it incorrectly. He should have gotten 6.
This is because exponents of 1/2 are the same as square roots.
[tex](36)^{1/2} = \sqrt{36} = 6[/tex]
Matt probably thought it was 36 times 1/2, which may explain how he got 18.
Matt rewrote the expression incorrectly. The expression is equivalent to 6. Option A is correct.
Given that,
Matt rewrote the given expression, he got 18. [tex](36)^{1/2}[/tex] Which statement is correct is to be determined.
In mathematics, it deals with numbers of operations according to the statements.
What is simplification?The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
Since matt made a mistake in his calculation, let correct the calculation and determined what should be the matt mistake.
Simplification
[tex]= (36)^{1/2}\\= (6^2)^{1/2}\\=(6)^{2 * 1/2}\\= 6[/tex]
Thus, Matt rewrote the expression incorrectly. The expression is equivalent to 6. Option A is correct.

a cup of coffee contains 150 milligrams of caffeine. if caffeine is eliminated from the body at a rate of 14% per hour, how long will it take for half of this caffeine to be eliminated from a person's body? round your answers to the nearest hour
A. 7 hours B. 6 hours C. 5 hours
D. 4 hours
Answer:
Step-by-step explanation:
14% of 150 mg = 0.14* 150 = 21 mg
21 mg will be eliminated from our body in an hour
150/21 = [tex]7\frac{3}{21}[/tex]
= 7 hours { rounding to the nearest}

Find the midpoint of the line segment joining the points R(-5,5) and S(4.6).
Hey there! I'm happy to help!
To find the x value of the midpoint, you add the x values and divide by 2.
-5+4=-1
-1/2=-1/2
For the y value, you add the y values and divide by 2.
5+6=11
11/2=5 1/2
So, the midpoint is (-1/2, 5 1/2).
