Step-by-step explanation:
The sum of the values of Point A and Point B is zero since Maya plotted Point B a distance that is exactly as far from zero as Point A is.
Answer: B) The sum of the values of Point A and Point B is zero.
Step-by-step explanation:
They are equally distant from 0, so they cancel eachother out.

Step-by-step explanation:
I hoped this helped:)
Answer:
2.2 or -2.2
Step-by-step explanation:
-5x^2=-25 first, divide by -5
x^2=5 next, take the square root of 5
The square root of 5 is approximately 2.2, and so you get either 2.2 or -2.2, since a negative times a negative is a positive, so it could be -2.2 as well.

2). The scale factor of two regular octagons is 52. Find the ratio of their
perimeters and the ratio of their areas, *
Answer:
Step-by-step explanationBy definition we have that the area of a regular octagon is:
A = 4.83L ^ 2
Where, L is the length of the octagon side.
the similarity ratio = the area ratio.
We have then:
similarity ratio = (50) / (18) = 25/9.
the ratio of the perimeters
A1 = 4.83L1 ^ 2
L1 ^ 2 = A1 / 4.83
L2 ^ 2 = A2 / 4.83
L1 ^ 2 / L2 ^ 2 = A1 / A2 = 25/9
L1 / L2 = 5/3
The perimeter is:
P1 = 8L1
P2 = 8L2
P1 / P2 = 8L1 / 8L2 = L1 / L2 = 5/3
answer:
similarity ratio:
25: 9
the ratio of the perimeters:
5: 3

A square has an area of 148.84m2.
Work out the perimeter of the square
Answer:
48.8m
Step-by-step explanation:
Formula for square area = [tex]a^{2}[/tex] = 148.84 [tex]m^{2}[/tex]
=> a = [tex]\sqrt{148.84}[/tex] = 12.2
Formula for square perimeter = 4a = 4 x 12.2 = 48.8 m
The perimeter of the given square is 48.8 m.
What is perimeter of a square?The perimeter of any closed geometrical object is defined as the distance around that object. The perimeter of a square is the distance covered by its four sides. Perimeter surrounds or outlines the shape in a two-dimensional plane.
Since all the sides of a square are equal, therefore, the perimeter of square will be 4 times its side, i.e. 4 × Side. It is measured in units, such as m, cm, in, ft, etc.
According to question,
Given area of a square = 148.84 m²
We all know that,
Area of a square = (Side)²
⇒ (Side)² = 148.84 m²
⇒ Side = √(148.84 m²)
⇒ Side = 12.2 m
Therefore, perimeter of the given square = 4 × Side
= 4 × 12.2
= 48.8 m
Hence the perimeter of a square = 48.8

Answer:
51
Step-by-step explanation:
largest number - smallest number
54 - 3 = 51
Answer:
51
step by step
Explanation: The range of a data set is the difference between the largest number in the data and the smallest number in the data set which in this case is 54 - 3 of 51. So the range of this data set is 51.
Mark and Doug work at the mall. Last week,
Mark worked five less than three times the
number of hours that Doug worked. If their total
number of combined hours was 13 more hours
than Mark worked, how many hours did they
work in total?
If Mark and Doug work at the mall and their total number of combined hours was 13 more hours than Mark worked, The number of hours they work in total is 47 hours.
How to find the hours worked?Let x represent the time Doug worked
let 3x - 5 represent the number of hours Mark worked
Hence,
x + 3x - 5 = 3x -5 +13
4x-5=3x-5+13
4x-5=3x+8
Add 5 to both side
4x-5+5 =3x+8+5
simplify
4x =3x +13
subtract 3x from both side
4x -3x = 3x + 13 =3x
1x = 13
x =13/1
x =13 (Doug)
Hence,
3x -5 where x = 13
3 (13) -5
= 39 -5
= 34 hours (Mark)
Total hours
(Doug + Mark)
= 13 hours + 34 hours
= 47 hours
Therefore the total hours is 47 hours.

Pedro throws a ball upward at a rate of 20 meters per
second from an initial height of 2 meters. The height
of the ball above the ground can be approximated by
h = -512 + 20t + 2, where t represents the amount of time,
in seconds, since the ball has been released.
What is the maximum height that the ball reaches?
Answer:
The maximum height that the ball reaches is of 3.96 meters.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].
In this question:
The height after t seconds is given by:
[tex]h(t) = -51t^2 + 20t + 2[/tex]
Which is a quadratic equation with [tex]a = -51, b = 20, c = 2[/tex]
What is the maximum height that the ball reaches?
This is [tex]h_v[/tex].
[tex]\Delta = b^2-4ac = 20^2 - 4(-51)(2) = 808[/tex]
[tex]y_{v} = -\frac{\Delta}{4a} = -\frac{808}{4(-51)} = 3.96[/tex]
The maximum height that the ball reaches is of 3.96 meters.

Step-by-step explanation:
We need to find the value of a.
We know that, a straight line makes an angle of 180°.
In this case,
a+3a+2a = 180
6a = 180
a = 30°
So, the value of a is equal to 30°.
