5. Abbey represented the perimeter of the rectangle with the expression 8x + 4. Determine if Abbey's
expression is equivalent to Brit's expression. Justify your reasoning.
Answer: I believe it is
Step-by-step explanation: if you add 3x + 3x you get 6x. You would then add the like terms which are x + x ( x is equal to one) and that to 6x and you get 8x then add 2+2=4 and you get 8x + 4

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
The m<3 = (2x + 10) and m<6 = (3x-15) find the value of x, m<3 and M<6
9514 1404 393
Answer:
x = 25; ∠3 = ∠6 = 60°
Step-by-step explanation:
Angles 3 and 6 are alternate interior angles, so are congruent.
2x +10 = 3x -15
25 = x . . . . . . . . . . . add 15-2x
2x +10 = 2(25) +10 = 60
The measures of angles 3 and 6 are 60°.

Step-by-step explanation:
A tire on a vehicle has a diameter of 30in. As it moves down the
road it makes 50 full revolution. What is the approximate distance
it traveled?
Answer:
94.25 in
Step-by-step explanation:
In one revolution, the tire moves a distance equal to its circumference. If the diameter is 30 in, the radius is half of that, 15 in. Circumference is 2 pi times the radius:
[tex]C=2\pi r= 2\pi (15) = 30\pi \approx 94.25 \text{ in.}[/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.

1) Let X represent the number of tires with low air pressure on a randomly chosen car. The probability of distribution of X is as follows:
X 0 1 2 3 4
P(X) 0.1 0.2 0.4 0.2 0,1
a) Find the probability of 1 tire with low air pressure P (1) =
b) Find the probability of more than 2 tires having low air pressure P (more than 2) =
c) P (all 4 tires) =
d) Compute the expected number of tires with low air pressure.
e) Compute the standard deviation for the number of tires with low air pressure.
Answer:
0.2 ; 0.3 ; 0.1 ; 2
Step-by-step explanation:
X 0 1 2 3 4
P(X) 0.1 0.2 0.4 0.2 0,1
a) Find the probability of 1 tire with low air pressure P (1) :
From probability distribution table Given :
P(1) = 0.2
b) Find the probability of more than 2 tires having low air pressure P (more than 2) =
P(x > 2) = p(3) + p(4)
P(x > 2) = 0.2 + 0.1 = 0.3
c) P (all 4 tires)
From the table :
P(x = 4) = 0.1
d) Compute the expected number of tires with low air pressure.
E(X) = Σx * p(x)
E(x) = (0*0.1) + (1*0.2) + (2*0.4) + (3*0.2) + (4*0.1) = 2

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.

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]
