Answer:
54
Step-by-step explanation:
8^2=64
64-8=56
56-2=54
I hope this is right
Examination:
8 would be inserted for y : 8^2-8-2
You would use PEMDAS to know solve the exponent first so 8 squared is 64. After you replace 8 squared with 64 you will move to the next step possible by the equation and PEMDAS. In this equation it is subtraction. So now you will subtracted 8 from 64 and will get 56 and then subtracted 2 and get 54. You solve left to right.

b. If 3x - 3 and 5x + 7° are the angle of a linear pair, find their measurement the angle
Answers
Answer:
x = 22°
the angles are: 63° and 117°
Step-by-step explanation:
a linear pair of angles total together to be 180°
so:
3x - 3 + 5x + 7 = 180
combune like terms:
8x = 176
divide both sides of the equation by 8:
x = 22°
the angles are: 63° and 117°

Eva payrolls for on a number cube and the number of cubes roll 24 times then what is a reasonable prediction for the number of successful Rolls
Answers
Answer:
The reasonable prediction for successful rolls is 4.
Step-by-step explanation:
Assuming the rolling cube is a fair 6 sided cube, so the probability of success of one roll is given as
[tex]P(Success)=\dfrac{Number\ of\ successful\ events}{Number\ of\ total\ events}[/tex]
[tex]P(Success)=\dfrac{1}{6}[/tex]
The total success is given as
[tex]P(Total\ Success)=P(Success)\times Number\ of\ events[/tex]
For 24 rolls it is given as
[tex]P(Total\ Success)=P(Success)\times Number\ of\ events\\P(Total\ Success)=\dfrac{1}{6}\times 24\\P(Total\ Success)=4[/tex]
So the reasonable prediction for successful rolls is 4.

Roxanna invested $10,000 in an account that earns 8.5% interest that is
compounded monthly. Determine the amount of money in the account in
15 years. (Lesson 7-10b)
Answers
Answer:
$35,100
Step-by-step explanation:
Given data
Principal=$10000
Rate= 8.5%
Time = 15 years = 180 months
The expression for monthly compounded interest is
A=P(1+r/12)^t
substitute
A=10000(1+0.085/12)^180
A=10000(1+0.007)^180
A=10000(1.007)^180
A=10000*3.51
A=$35,100
Hence the balance is $35,100

[tex]given \: that \: p = {x}^{2} + 4x - 2 \: and \: q = 2x - 1 \: and \: q - p = 2 \: find \: x[/tex]
Answers
Answer:
x= -1
Step-by-step explanation:
p= x² +4x -2 -----(1)
q= 2x -1 ------(2)
q -p= 2 -----(3)
Substitute (1) and (2) into (3):
2x -1 -(x² +4x -2)= 2
2x -1 -x² -4x +2= 2 (Expand bracket)
-x² -2x +1=2 (Simplify)
x² +2x +2 -1= 0 (Bring all terms to one side)
x² +2x +1= 0
(x +1)²= 0 (Factorise)
x +1= 0 (Square root both sides)
x= -1 (-1 on both sides)

Mark rides his bike from his house to the closest edge of the park, across the length of the park, and then back home. The distance from his house to the closest edge of the park is 0.9 km and the distance from the far side of the park to his house is 1.6 km. The map shows the path Mark took on his bike. If ∠B = 85° on the map, then use the law of cosines to determine the length of the park in kilometers.
Answers
Answer:
The length of the park is approximately 1.77 kilometers
Step-by-step explanation:
The law of cosines is most appropriate when the measures of two sides and the included angle formed n=by the path of motion is known
The given parameters of the question are;
The distance from Mark's house to the edge of the park, a = 0.9 km
The distance from the far side of the park to Mark's house, c = 1.6 km
Whereby the included angle between lines, 'a' and 'c' is the ∠B = 85°, by cosine rule, we have;
b² = a² + c² - 2·a·c·cos(B)
Where;
b = The length of the park in kilometers
By plugging in the known values of 'a', 'b', and 'c', we get;
b² = 0.9² + 1.6² - 2 × 0.9 × 1.6 × cos(85°) ≈ 3.11899146089
∴ b = √(3.11899146089) ≈ 1.76606666377
Therefore, the length of the park, b ≈ 1.77 km.

The circle below has center Z. Suppose that m XY = 122°. Find the following.
Answers
Answer:
m∠XZY = 122°
m∠XWY = 61°
Step-by-step explanation:
From the picture attached,
A circle has been given with center as Z.
∠XZY is a central angles subtended by the arc XY,
Therefore, measure of angle XZY will be equal to measure of ∠XZY.
m(∠XZY) = m(arc XY) = 122°
By another property of the circle,
"Inscribed angle measures the half of the central angle intercepted by the same arc."
Therefore, m∠XWY = [tex]\frac{1}{2}(\angle XZY)[/tex]
= [tex]\frac{1}{2}(122)[/tex]
= 61°

Answers
Answer:
C
Step-by-step explanation:
I did this by graphing the points on paper and then forming an equation from there. Another way is to do to slope equation. The slope equation is: [tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex], so you would just fill it in here. (4+4) (I did PLUS since subtracting a negative is adding a postive number). This equals 8. (0-2) is -2, so 8/-2 is -4x. For the y-intercept, it is already shown in the equation. This is 4 because if x is 0, then that is the y-intercept. So: y=-4x+4.
