Answer:
C
Step-by-step explanation:
You combine like terms and then order them according to their exponents (order)
Since the 4 has a negative but is going to get subtracted it becomes positive and therefore added
2[tex]x^5[/tex] +(7x³ + 4x³) - 5x² = 2[tex]x^5[/tex] + 11x³ - 5x²
No links or weird answers, please :(
Are all of these tables functions? Explain why or why not.
Also, I think that they may be all functions. But I'm not so sure so I want to know what you think.

Answer:
Number 7 is 25%
Step-by-step explanation:
You take the original price and subtract it by each percentage until you get 30.
$40.00 - 15% = 34
$40.00 - 20% = 32
$40.00 - 40% = 24
$40.00 - 25% = 30
Therefore, the answer is 25% !

integrate the following:
[tex] \displaystyle \int \frac{ \cos ^{2} (x) - \cos ^{2} ( \alpha ) }{ \cos( x) - \cos( \alpha ) } [/tex]
Answer:
[tex] \displaystyle \sin(x) + x\cos( \alpha ) + \rm C[/tex]
Step-by-step explanation:
we are given
[tex] \displaystyle \int \frac{ \cos ^{2} (x) - \cos ^{2} ( \alpha ) }{ \cos( x) - \cos( \alpha ) } dx[/tex]
we want to Integrate it
notice that, the denominator can be rewritten by using algebraic identity
remember that,
[tex] \displaystyle {a}^{2} - {b}^{2} = ( a + b)(a - b)[/tex]
therefore
rewrite the denominator by using the identity:
[tex] \displaystyle \int \frac{ ((\cos (x) + \cos ( \alpha) ) ( \cos(x) - \cos( \alpha ) ) }{ \cos( x) - \cos( \alpha ) }dx [/tex]
reduce fraction:
[tex] \displaystyle \int \frac{ ((\cos (x) + \cos ( \alpha) ) ( \cancel{ \cos(x) -\cos( \alpha ) ) }}{ \cancel{\cos( x) - \cos( \alpha ) } }dx[/tex]
[tex] \displaystyle \int \cos(x) + \cos( \alpha ) dx[/tex]
recall that,
[tex] \rm\displaystyle \int f(x) \pm g(x)dx =\int f(x) \pm \int g(x)dx[/tex]
by that
we get
[tex] \displaystyle \int \cos(x) dx + \int \cos( \alpha )dx [/tex]
we also know that,
[tex] \displaystyle \int \cos(x) = \sin(x)dx [/tex]
and also the Integration of a constant is always cx
so,
[tex] \displaystyle \sin(x) + x\cos( \alpha ) [/tex]
and of course we have to add constant
[tex] \displaystyle \sin(x) + x\cos( \alpha ) + \rm C[/tex]

Do
Wed Apr 21
Answer:
Options C and D are the correct options.
Step-by-step explanation:
Option A
cos(H) = 0.3846
By applying cosine rule in ΔFGH,
cos(H) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{36}{39}[/tex]
= 0.9231
False
Option B
cos(G) = 0.9231
By applying cosine rule in ΔFGH,
cos(G) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{15}{39}[/tex]
= 0.3846
False
Option C
sinG = 0.9231
By applying sine rule in ΔFGH,
sin(G) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{36}{39}[/tex]
= 0.9231
True
Option D
tanG = 2.4
By applying tangent rule in ΔFGH,
tanG = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{36}{15}[/tex]
= 2.4
True
Therefore, Options C and D are the correct options.
On Eduardo's workbench are the following
paint cans.
• 3 cans of red paint
• 5 cans of blue paint
• 8 cans of green paint
• 4 cans of yellow paint
Eduardo will randomly choose one can of
paint. What is the probability that he will
choose a can of red paint or a can of blue
paint? (71A, 7.1B, 7.1F)
Answer: 2/5
Step-by-step explanation:
Number of cans of red paint = 3
Number of cans of blue paint = 5
Number of cans of green paint = 8
Number of cans of yellow paint = 4
Total number of cans of paint = 20
The probability that Eduardo will
choose a can of red paint or a can of blue will be:
= P(red) + P(blue)
= 3/20 + 5/20
= 8/20
= 2/5
The probability is 2/5.
A circle is centered on point B. Points A,C and D lie on its circumference. If ∠ABC measures 35 degrees what does ∠ADC measure
Answer: [tex]325^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]\angle ABC=35^{\circ}[/tex]
A, C, and D lie on the circumference of the circle
from figure,
[tex]\angle ABC+x=360^{\circ}\quad [\text{angle around a point is 360}]\\\Rightarrow 35^{\circ}+x=360^{\circ}\\\Rightarrow x=325^{\circ}[/tex]

Ann purchased a prepaid phone card for $20. Long distance calls cost 14 cents a minute using this card. Ann used her card only once to make a long distance call.If the remaining credit on her card is 14.26,how many minutes did her call last?
Answer:
The correct answer is; Ann was on the call for 41 minutes.
Step-by-step explanation:
20-14.26 is equivalent to 5.74, in which you divide that by .14 (fourteen cents) and get 41.
An angle measuring 28.3 radians is drawn in standard position?
In what quadrant will the terminal side of this angle lie?
Express your answer as a Roman numeral.
Answer:
The terminal side of angle will lie in thirds quadrant
Step-by-step explanation:
Given the angle is 28.3 degree radians
Converting it into degrees we get -
28.3rad × 180/π = 1621.471°
Total 360 degrees rotation in this angle
1621.471°/360 = 4
SO the remaining degrees 181.471
The angle grater than 180 lies in third quadrant.
The terminal side of angle will lie in thirds quadrant

Not a solution: 129 and [tex]10\frac{2}{3}[/tex]
Step-by-step explanation:
20 ≥ 5 + 3x
3x + 5 ≤ 20
3x ≤ 20 - 5
3x ≤ 15
x ≤ 5
x must be LESS than or EQUAL to 5
is this proportional or non-proportional?
