Answer:
(2x-5)(4x^2+10x+25)
Explanation:
Factoring difference of cubes (a3−b3): (a−b)(a2+ab+b2)
Here, a is 2x because the cube root of 8 is 2 and the cube root of x3 is x, b is 5 because the cube root of 125 is 5.
Plug the numbers in:
(2x−5)((2x)2+2x⋅5+52)
(2x−5)(22x2+10x+25)
(2x−5)(4x2+10x+25)
Answer:
8x^3 can also be written as [tex](2x)^{3}[/tex].
-125 can also be written as [tex]-5^{3}[/tex].
Factoring the polynomial:
[tex](2x)^3+(-5)^3[/tex]
Which represents an even function?
A. y = cos(x)
B. y = sin(x)
C. y = tan(x)
D. y = cot(x)
NVM I DID IT
ANSWER: A
Answer:
A. y=cos(x)
Step-by-step explanation:
I just want the points. im taking the quiz rn.
From the given options, the only even function is the cosine function, so the correct option is A.
Which of the options is an even function?First, an even function is a function with the property:
f(x) = f(-x)
So these functions are symmetrical across the y-axis.
Is ratter easy to remember that the sin function is actually odd, this means that:
sin(-x) = -sin(x).
Then the tangent function (and the cotangent function) are also odd, because:
tan(x) = sin(x)/cos(x).
In the other hand, for the cosine function we have:
cos(-x) = cos(x)
And as shown in the graph below, it is symmetrical across the y-axis.
Then we conclude that the correct option is A.

Find the distance between the points (2,0) and (-4,6)
Answer:
let's see what to do buddy...
Step-by-step explanation:
We have this equation to find the distance between two points :
a = ( 2 , 0 ) and b = ( -4 , 6 )
[tex]distance = \sqrt{ {( \: y(b) - y(a) \: })^{2} + ( \: {x(b) - x(a)} \: )^{2} } \\ [/tex]
Now just need to put the coordinates in the equation :
[tex]distance = \sqrt{ ({6 - 0})^{2} + ({ - 4 - 2})^{2} } \\ distance = \sqrt{ {6}^{2} + ({ - 6})^{2} } = \sqrt{36 + 36} \\ distance = \sqrt{36 \times 2} = 6 \sqrt{2} [/tex]
And we're done.
Thanks for watching buddy good luck.

Answer:
The only thing I can think of is -2.
Step-by-step explanation:
-9 + 7 = -2
I'm not sure if you wrote the questions or the answers wrong, but if I'm reading it right the answer should be -2, not 2. Unless you meant to write 9 + -7, in which case the answer would be 2.

2. The Perimeter of a square is P. Which equation could be used to find its area (A)?
a. A = P2
b. A = (p/4)^2
c. A = 4P
d. A = (√p)^2
Answer:
A = (P/4)²
Step-by-step explanation:
Given
Perimeter = P
Required
Determine the area
First, we need to calculate the sides of the square using:
[tex]P = 4L[/tex]
Where L represents the length of the side
Make L the subject
[tex]L = \¼P[/tex]
Area is calculated as thus:
[tex]Area = L\²[/tex]
Substitute ¼P for L
[tex]Area = (\¼P)\²[/tex]

Rental car company A charges an initial fee of $35 plus $0.75 per mile. Rental car company B charges $0.50 per mile and an initial fee of $55. For what number of miles will the cost of both rental car companies be the same? True or False: 35 + 0.75x ≥ 0.5x + 55 be used to solve the real-world problem. If false, explain in detail what needs to be changed in the real-world problem so 35 + 0.75x ≥ 0.5x + 55 can be used to solve it.
Answer:
Let it be for x miles.
40+15+0.25x=45+0.35x
10 =0.1x
x=100
The mile is 45+0.35*100= 80 or 40+15+0.25*100 =80

Please help!!! I really don’t get this only I get where the 3 are but please help me for the 4/5 and -0.4!
Answer:
-0.4 should be in between 0 and -0.5, however be as close to -0.5 as possible while not being ON -0.5.
3 4/5 should be in between 3 and 4, so you can split 4/5 into 8/10 which are equal to each other. Then you can pretend to split the 3 and 4 gap into 10 equal pieces. After you split the gap, count 8 parts to the left of 3.
