Explanation:
The range is {2, -1, 5, -8, 9} which sorts to {-8, -1, 2, 5, 9}. This is the set of y coordinates of the points given. Each point is of the form (x,y).
Since the domain and range are the same set in this case, we must have those value mentioned as x coordinates of the points.
The domain is the set of x coordinates of the points given.
The values -8, -1, 2, and 9 are already used as x coordinates. The only thing missing is the 5.

What is the distance around the perimeter of the garden? 60 ft 60 startroot 3 endroot ft 120 ft 120 startroot 3 endroot ft
The distance around the perimeter would be 120 ft.
What is perimeter?Perimeter is the distance around the edge of a shape.
The complete question is
A garden is designed in the shape of a rhombus formed from 4 identical 30°-60°-90° triangles. The shorter distance across the middle of the garden measures 30 feet.
A rhombus is shown. Lines are drawn from each point to the opposite point to form 4 right triangles. The other 2 angle measures are 30 and 60 degrees. The base length of each triangle is 15 feet.
What is the distance around the perimeter of the garden?
let AE is the half of the diagonal AC.
AC = 30 ft.
So, AE = ½ * 30
AE = 15 ft
Now, using trigonometry
sin 30 = 15/AD
0.5= 15/AD
AD= 30 ft
Hence, distance around the perimeter would be: AD+AD+AD+AD=
=30 ft + 30 ft + 30 ft + 30 ft
= 120 ft.

When the height of the prism doubles, the percentage increase in the volume is 100%
How to determine the percentage increase?The volume of a prism is:
V₁ = BH
Where:
B represents the base area and H represents the height.
When the height doubles, the volume becomes
V₂ = 2BH
The percentage increase is then calculated using:
%Increase = (V₂ - V₁)/V₁
So, we have:
%Increase = (2BH - BH)/BH
Evaluate
%Increase = 1
Express as percentage
%Increase = 100%
Hence, the percentage increase is 100%

what is the value of y in this triangle?
Answer:
26 degrees.
Step-by-step explanation:
The angles of triangles will always add up to 180 degrees.
The first angle is 50 degrees.
The second angle, is shown with a 76 degree angle next to it.
Since this is a 180 degree line, we can find the angle of the bottom right corner by doing 180 - 76. 180 - 76 is 104.
104 + 50 = 154 degrees.
The remaining 26 degrees is the answer to the value of y.

(x - 6)². Multiply it and simplify it
Answer:
x^2-12x+36
Step-by-step explanation:
The first step in solving this equation is to expand the square which makes the equation (x-6)(x-6). Then you distribute the x to both parentheses which leaves you with x^2-6x, and then you distribute the 6 to both parentheses which gives you 6x+36. Then add both binomials which leaves you with x^2-12x+36. The reason it is +36 and not -36 is because you are multiplying a negative 6 by another negative 6.

For no solution,

For one solution,
2x + 9 + 3x + x = 15
For infinitely many solutions,
2x + 9 + 3x + x = 6x + 9
Step-by-step explanation:
Step-by-step explanation:
1. 2x + 9 + 3x + x = 6x
6x + 9 = 6x
Subtract 6x from both sides,
9 = 0 which is absurd and hence the equation has no solution.
2. 2x + 9 + 3x + x = 15
6x + 9 = 15
Subtract 9 from both sides.
6x = 6
Divide both sides by 6.
x = 1 and this is the only solution.
3. 2x + 9 + 3x + x = 6x + 9
6x + 9 = 6x + 9
Subtract 6x from both sides,
9 = 9, both sides are balanced which means, the equation has infinitely many solutions.

Step-by-step explanation:
Perimeter is all of the lengths of the sides added together. I started by adding all of the whole numbers:
35+10+12+15+24+12+10=118
Then I added the fractions (after making the denominators equal by multiplying the 3/7, 1/7, 2/7 all by 2)
6/14+2/14+4/14+3/14+1/14+4/14+2/14= 22/14
Then I subtracted 14 from 22 to take out our whole number (which would be 14/14 or 1), and see that we are left with 8.
This means that our answer is 119 8/14 or 119 4/7

Answer:
Step-by-step explanation:
Remark
Anything multiplied by 0 = 0. So the whole right side is 0.
(6x - 9)*3 - 1 = 0 Add 1 to both sides.
(6x - 9)*3 - 1 + 1 = 0 + 1 Combine
(6x - 9)*3 = 1 Divide both sides by 3
(6x - 9)*3/3 = 1/3 Simplify
(6x - 9) = 1/3 Remove brackets. Add 9 to both sides
6x - 9+9 = 9 1/3 Combine
6x = 9 1/3
6x = 28/3 Divide both sides by 6
6x / 6 = 28/3 // 6 Invert the 6 and multiply.
x = 28/3 * 1/6
x = 28/18

the scale factor of the larger of two similar rectangular prisms is 1/8. the surface area of the larger prism is 740 ft2. identify the surface area, rounded to the nearest tenth, of the smaller prism
Answer:
11.6 ft²
Step-by-step explanation:
We assume the 1/8 scale factor is the ratio of the linear dimensions of the smaller of the prisms to the larger. The ratio of areas will be the square of the ratio of the linear dimensions.
__
The ratio of areas will be ...
smaller area / larger area = (scale factor)²
smaller area = (larger area)×(scale factor)² . . . multiply by the denominator
smaller area = (740 ft²) × (1/8)² = 11.5625 ft² . . . use given values
The surface area of the smaller prism is about 11.6 square feet.

Calculate, correct to two decimal places
2. the bearing of R from P
3. |PR|
The bearing of R from P is 019 and the distance |PR| is 8.75
The complete questionA cyclist set out from a town P on a bearing of 060 to a town Q, 5 km away. He then moves on a bearing of 345 to a town R, 6km from Q.
The diagram that represents the informationSee attachment
The bearing of R from PStart by calculating the distance PR using the following cosine ratio
PR² = PQ² + QR² - 2 * PQ * PR cos(Q)
Substitute known values
PR² = 5² + 6² - 2 * 5 * 6 cos(105)
Evaluate
PR² = 76.53
Take the square root of both sides
PR = 8.75
Next, calculate angle R using the following sine ratio
PQ/sin(R) = PR/sin(Q)
Substitute known values
5/sin(R) = 8.75/sin(105)
Evaluate the quotient
5/sin(R) = 9.06
Multiply both sides by sin(R)
9.06 * sin(R) = 5
Divide both sides by 9.06
sin(R) = 0.5519
Take the arc sin of both sides
R = sin⁻¹(0.5519)
Evaluate
R = 34
Calculate angle P using:
P = 180 - 34 - 105
P = 41
The bearing of R from P is then calculated as:
Bearing = 060 - 41
Evaluate
Bearing = 019
Hence, the bearing of R from P is 019
The distance |PR|In (b), we have:
PR = 8.75
Hence, the distance |PR| is 8.75
