What is -a⁻² if a = -5?
Answer:
25
Step-by-step explanation:
First, plug -5 in for a, -(-5)^2. We treat the negative on the outside of the paranthese as a -1 so we do -1 times -5 and we get 5. Then we square 5 and get 25.

Is (2,0) a solution for the equation -3+9y=-6
Answer:
[tex]y=-\frac{1}{3}[/tex]
Step-by-step explanation:
- 3 + 9y = - 6
- 3 + 3 + 9y = - 6 + 3
9y = - 3
9y ÷ 9 = - 3 ÷ 9
[tex]y=- \frac{1}{3}[/tex]

A regular heptagon is shown below. What is the value of x?
Answer:
108+x=180
X=180-108
X=72
The value of the exterior angle (x) in a regular heptagon is approximately 51.43 degrees.
Given is a regular heptagon with one of the exterior angle be x we need to find the value of x
To find the value of the exterior angle of a regular heptagon, we can use the formula:
Exterior Angle = 360 degrees / Number of Sides
In this case, the heptagon has seven sides, so we can substitute the values into the formula:
Exterior Angle = 360 degrees / 7
Exterior Angle ≈ 51.43 degrees
Therefore, the value of the exterior angle (x) in a regular heptagon is approximately 51.43 degrees.

Answer:
y = -0.25x + 40 ; $26,000
Step-by-step explanation:
From the graph attached ;
The regression equation, y could be obtained :
y = mx + c
m = slope = Rise / Run = (y2 - y1) / (x2 - x1)
Slope = (15 - 40) / (100 - 0)
Slope = - 25 / 100
Slope = - 0.25
c = intercept, where the regression line crosses the y-axis, from. The graph, c = 40
The regression equation goes thus :
y = -0.25x + 40 ; y = price of car ; x = number of miles driven
Price of car that has been driven for 56000 miles
y = - 0.25(56) + 40
y = - 14 + 40
y = 26
Hence, price of car is $26,000
A filing cabinet is 2 yards long by 2 feet wide by 48 inches high. What is the volume of the filing cabinet in cubic inches? Enter your answer in the box.
Answer:
82944 in^3
Step-by-step explanation:
Volume = length x breadth x height
Before volume can be calculated, feet and yards needs to be converted to inches
1 yard = 36 inches
2 x 36 = 72 inches
1 foot = 12 inches
2 x 12 = 24 inches
Volume = 72 x 48 x 24 = 82944 in^3

Two sides of a triangle measure 8 cm and 15 cm. Whi[:h could be the length of the third side?
O 6 cm
O 18 cm
O 24 cm
O 28 cm
18 cm is correct .
Step-by-step explanation:
The sum of two smaller sides is greater that the largest side.
It is given that the two sides of a triangle measure 8 cm and 15 cm.
Case 1: Let 8 cm and 15 cm. are smaller side. So,
Third side < 8 + 15
Third side < 23
It means 3rd side must be less than 23
Case 2: Let 15 cm is the largest side.
15 < Third side + 8
15 - 8 < Third side
7 < Third side
It means 3rd side must be greater than 7.
Since only 18 is less than 23 and greater than 7, therefore the possible length of third sides is 18 cm and option 2 is correct.

If the angles
are represented in degrees, find both angles:
sin(x + 7) = cos(4x + 8)
Answer:
x = -1/3
Step-by-step explanation:
We have,
sin(x + 7) = cos(4x + 8)
We need to find the value of x.
We know that,
sin(90-x) = cosx
So,
sin(90-(x + 7)) = cos(4x + 8)
cos(x+7) = cos(4x + 8)
i.e.
(X+7) = (4x+8)
7-8 = 4x-x
-1 = 3x
x = -1/3
Answer:
sin(22 ∘ ) = cos(68∘ )
Step-by-step explanation:
Sin(x+7)=cos(4x+8)
(x+7) + (4x+8) = 90
x + 7 + 4x + 8 = 90
5x + 15 = 90
−15 = −15
5x/5 = 75/5
x = 15
Answer: sin(22 ∘ ) = cos(68∘ )
