Answer:
71°
Step-by-step explanation:
Remember, all the interior angles of a triangle add up to 180 degrees. Therefore, we can find the value of x by subtracting the values of the other angles from 180:
x=180-82-27
x=71
Which expression is equivalent to x with the power of 2 +2x+2?

The answer is the fourth one
Step-by-step explanation:
Consider this equation.
cos(θ) = 4sqrt41/41
If θ is an angle in quadrant IV, what is the value of sin(θ) ?
Answer:
A. -5√41/41Step-by-step explanation:
Let the horizontal leg = 4√41 and the hypotenuse = 41 as
cosine = adjacent leg / hypotenuse.Then the vertical leg is:
√(41² - 16*41) = √25*41 = 5√41Since the vertical leg is below the x-axis, its value is -5√41
Then we have:
sin (θ) = -5√41/41Correct choice is A

Sarah goes to dinner with two friends the total cost of dinner is $61.92 her friends pay 2/3 of the total cost exactly how much does Sarah pay
Answer:
the amount paid by Sarah is $20.64
Step-by-step explanation:
Given that
The total cost of the dinner is $61.92
And her friends pay 2 by 3
We need to find out the amount paid by Sarah
Since her friends pay 2 by 3 of the total cost
That means the remaining should be paid by Sarah i.e. 1 by 3
So, we need to multiply 1 by 3 with the total cost of the dinner i.e.
= 1 ÷3 × $61.92
= $20.64
Hence, the amount paid by Sarah is $20.64

Tenemos 2000 baldosascon las que nos proponrmos embaldosar dos habitaciones.Para la 1ª gastamos 3/5 de ellas,y con la 2ª,3/4de las que qudaron.¿Cuántas utilizamos para cada habitación y cuántas sobraron?
Answer:
En la primera habitación son usadas 1200 baldosas.
En la segunda habitación son usadas 600 baldosas.
Sobraron 200 baldosas.
Step-by-step explanation:
Tienes 2000 baldosas, con las que se propone embaldosar dos habitaciones.
Para la primera habitación se han gastado [tex]\frac{3}{5}[/tex] de las baldosas. Esto se expresa como:
[tex]\frac{3}{5}*2000[/tex]
Para multiplicar una fracción por un número entero, el número entero n se puede escribir como la fracción [tex]\frac{n}{1}[/tex]. Luego se multiplica los numeradores y denominadores. En este caso:
[tex]\frac{3}{5}*2000=\frac{3}{5}*\frac{2000}{1} =\frac{3*2000}{5*1} = \frac{6000}{5}[/tex]
Para reducir la fraccion, divide 40 entre 10
[tex]\frac{6000}{5} =[/tex] 6000 ÷5= 1200
Entonces en la primera habitación son usadas 1200 baldosas. Por lo que las que quedan se calcula como:
2000 - 1200= 800 baldosas
De esta cantidad de baldosas que quedaron, [tex]\frac{3}{4}[/tex] son usadas para embaldosar la segunda habitación. Esto se expresa como:
[tex]\frac{3}{4}*800[/tex]
Resolviendo de igual manera que en el caso de la primer habitación se obtiene:
[tex]\frac{3}{4}*800=\frac{3}{4}*\frac{800}{1} =\frac{3*800}{4*1} =\frac{2400}{4}[/tex]= 2400 ÷ 4= 600
Entonces en la segunda habitación son usadas 600 baldosas. Por lo que, teniendo en cuenta que se tenían 800 baldosas que quedaron de la primera habitación, las baldosas restantes se calculan como:
800 - 600= 200 baldosas
Sobraron 200 baldosas.
Rewrite as equivalent rational expressions with denominator (x+3)(x−4)(x+4)
An equivalent rational expressions with denominator (x+3), (x−4) and (x+4) is (3x²+6x-16)/(x³+3x²-16x-48).
The given denominator are (x+3), (x−4) and (x+4).
What is a rational expressions?A mathematical expression that may be rewritten to a rational fraction, an algebraic fraction such that both the numerator and the denominator are polynomials.
Here, an equivalent rational expressions is
[tex]\frac{1}{x+3}+\frac{1}{x-4} +\frac{1}{x+4}[/tex]
The LCM of denominators is (x+3)(x-4)(x+4)
= (x+3)(x²-16)
= x(x²-16)+3(x²-16)
= x³-16x+3x²-48
= x³+3x²-16x-48
Now, [tex]\frac{(x-4((x+4)+(x+3)(x+4)+(x+3)(x-4)}{x^3+3x^2-16x-48}[/tex]
= (x²-16+x²+7x+12+x²-x-12)/(x³+3x²-16x-48)
= (3x²+6x-16)/(x³+3x²-16x-48)
Hence, an equivalent rational expressions with denominator (x+3), (x−4) and (x+4) is (3x²+6x-16)/(x³+3x²-16x-48).

Anthony wants to find the value of k for which given points W(0,-2), I(2,0) and L(5,k) are collinear
A. K=-3
B. K=1/3
C. K=1/2
D. K=2
E. K=3
F. K=-1/3
Given:
The three points are W(0,-2), I(2,0) and L(5,k).
To find:
The value of k for which the given points are collinear.
Solution:
We know that, three points are collinear if the area of the triangle formed by these three points is 0.
[tex]\dfrac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|=0[/tex]
[tex]x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)=0[/tex]
The three points are W(0,-2), I(2,0) and L(5,k). So,
[tex]0(0-k)+2(k-(-2))+5(-2-0)=0[/tex]
[tex]0+2(k+2)+5(-2)=0[/tex]
[tex]2k+4-10=0[/tex]
[tex]2k-6=0[/tex]
Adding 6 on both sides, we get
[tex]2k=6[/tex]
[tex]k=\dfrac{6}{2}[/tex]
[tex]k=3[/tex]
Therefore, the correct option is E.
The price of a 32 pack of water at heb is $2.98. The tax rate is 8% what is the final cost of the water
Answer:
The final cost of the water is $3.22.
Step-by-step explanation:
In order to find the answer, you have to add the tax to the price of the 32 pack of water by calculating 8% of the price and adding that amount to it.
2.98*8%=0.24
2.98+0.24=3.22
According to this, the answer is that the final cost of the water is $3.22.

John was visiting four cities that form a rectangle on a coordinate grid at A(0, 4), B(4, 2), C(1, -4) and D(-3, -2). What is the area of the space that cities enclose? Round your answer to the nearest whole number. Do not include units in your answer.
Answer:
[tex]Area = 30[/tex]
Step-by-step explanation:
Given
Rectangle coordinates
[tex]A = (0,4)[/tex]
[tex]B = (4,2)[/tex]
[tex]C = (1,-4)[/tex]
[tex]D =(-3,-2)[/tex]
Required
The area of the rectangle
The area is calculated as:
[tex]Area = Length* Width[/tex]
The length of the rectangle will be represented as:
[tex]Length = AB = CD[/tex]
And the width is:
[tex]Width = BC = AD[/tex]
Calculate distance AB using:
[tex]AB = \sqrt{(x_1 - x_2)^2 +(y_1 - y_2)^2 }[/tex]
Where:
[tex]A = (0,4)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]B = (4,2)[/tex] [tex]--- (x_2,y_2)[/tex]
[tex]AB = \sqrt{(0 - 4)^2 +(4 - 2)^2 }[/tex]
[tex]AB = \sqrt{(- 4)^2 +(2)^2 }[/tex]
[tex]AB = \sqrt{16 +4 }[/tex]
[tex]AB = \sqrt{20}[/tex]
Calculate distance BC using:
[tex]BC = \sqrt{(x_1 - x_2)^2 +(y_1 - y_2)^2 }[/tex]
[tex]C = (1,-4)[/tex] [tex]---(x_1,y_1)[/tex]
[tex]B = (4,2)[/tex] [tex]--- (x_2,y_2)[/tex]
[tex]BC = \sqrt{(1 - 4)^2 +(-4 - 2)^2 }[/tex]
[tex]BC = \sqrt{(- 3)^2 +(-6)^2 }[/tex]
[tex]BC = \sqrt{9 +36}[/tex]
[tex]BC = \sqrt{45}[/tex]
So, the area is:
[tex]Area = Length * Width[/tex]
[tex]Area = AB * BC[/tex]
[tex]Area = \sqrt{20} * \sqrt{45}[/tex]
[tex]Area = \sqrt{20 * 45}[/tex]
[tex]Area = \sqrt{900[/tex]
[tex]Area = 30[/tex]

Which function describes the vertical shift up 2 units and left 2 units to the original function: f(x) = ex
Answer:
g(x) = e^(x + 2) + 2
Step-by-step explanation:
First, let's describe the shifts.
Vertical shift.
For a function f(x), a vertical shift of N units is written as:
g(x) = f(x) + N
If N is positive, then the shift is upwards.
If N is negative, then the shift is downwards.
Horizontal shift.
For a function f(x), a horizontal shift of N units is written as:
g(x) = f(x - N)
If N is positive, the translation is to the right
If N is negative, the translation is to the left.
Now let's solve the question.
f(x) = e^x
First, we have a vertical shift up of 2 units, then:
g(x) = f(x) + 2
Now we have a shift to the left of 2 units:
g(x) = f(x - (-2)) + 2
g(x) = f(x + 2) + 2
Then:
g(x) = e^(x + 2) + 2

Answer:
f(x)= (x-5)(x+6)
Step-by-step explanation:
First, we find the factors of -30 that add up to +1
We can use 6 and -5
6+(-5)=1
f(x)= x^2+6x - 5x-30
then, we do group factorization
f(x)= x(x+6)- 5(x+6)
f(x)= (x-5)(x+6)
