write the coordinate notation for the following:
rotation in the direction of 90°: (x,y) becomes (y,-x) rotation of (x,y) at 90 degrees counterclockwise results in (-y,x) Rotating (x, y) 180 degrees both clockwise and counterclockwise results in (-x,-y) Rotating (x,y) in a 270° clockwise direction (-y,x).Upon 360-degree rotation, a point with the coordinates (x, y) is produced.
How is rotation calculated?
The number of central angles multiplied by the size of each central angle gives the angle of rotation between the two points or vertices: rotational angle =m = m
The term "order of rotation" refers to how many times a figure appears the same after a full 360-degree rotation. The angle of rotation can also be used to compute the order of rotation. A figure's rotational order can be determined using the angle of rotation (360°). A line segment rotates at a 180° angle.
Precession, nutation, and intrinsic rotation are the names of these rotations.

which equation represents the line that passes through the points -3 7 and 9 -1
EXPLANATION
Given ordered pairs: (-3,7) and (9,-1)
(x1,y1) (x2,y2)
The equation that represents the line that passes through the points will be given as:
y = mx + b
First, we need to calculate the slope:
[tex]\text{Slope = }\frac{(y2-y1)}{(x2-x1)}=\frac{(-1-7)}{(9-(-3))}=\frac{(-8)}{(12)}=-\frac{2}{3}[/tex]Now, taking either one pair, we can calculate the value of b in this way:
[tex]7=-\frac{2}{3}(-3)\text{ + b}[/tex][tex]7=\frac{6}{3}+b[/tex]Simplifying:
[tex]7\text{ = }2\text{ + b}[/tex]Clearing b:
[tex]7-2=5=b[/tex]Finally, the equation will be:
[tex]y=-\frac{3}{2}x+5[/tex]
write an equation of the line with the given slope, m, and y intercept (0,b)
Given Data:
[tex]\begin{gathered} m=\frac{1}{4} \\ b=0 \end{gathered}[/tex]The general equation of a line passing through a point of cordinates (x, y) can be written as,
[tex]y=mx+b[/tex]Therefore substituting for m and b, we can write, the line equation as,
[tex]y=\frac{1}{4}x+0[/tex]Thus the equation is, y = (1/4)x.

Based on the triangle sum theorem, the measure of <RSP is: B. 49°
How to Apply the Triangle Sum Theorem?According to the triangle sum theorem, every triangle has a sum of 180 degrees when all its interior angles are added together.
Since lines PS and QR are parallel lines, therefore:
5y + 14 = 8y - 13 [alternate angles are congruent]
Solve for the value of y
5y - 8y = -14 - 13
-3y = -27
-3y/-3 = -27/-3
y = 9
(8y - 13) + 3x + (2x + 1) = 180 [triangle sum theorem]
8y - 13 + 3x + 2x + 1 = 180
8y - 12 + 5x = 180
Plug in the value of y
8(9) - 12 + 5x = 180
72 - 12 + 5x = 180
60 + 5x = 180
5x = 180 - 60
5x = 120
x = 120/5
x = 24
Measure of <RSP = 2x + 1 = 2(24) + 1
Measure of <RSP = 49°

The error interval for car and person are:
2275 ≤ 2276 < 2276.5 and 60.55 ≤ 60.6 < 60.65 respectively.
Given, the mass of a car is 2276 kg.
we are asked to determine the nearest kilogram.
the car: rounded to the nearest kilogram
so 2275 ≤ 2276 < 2276.5
therefore, a = 2275.5
and b = 2276.5
The mass of a person is 60.6 kg.
we need to round it to 1 decimal place.
the person: rounded to 1 decimal place,
so, 60.55 ≤ 60.6 < 60.65
therefore, a = 60.55
and b = 60.65
Hence the error interval for the combined mass, m, of the car and the person is 2275 ≤ 2276 < 2276.5 and 60.55 ≤ 60.6 < 60.65 respectively.

The line's equation is:
[tex]21x+45y=-6[/tex]To get slope and y-intercept, we have to re arrange this into slope intercept form, that is:
y = mx + b
Where
m is the slope
b is the y-intercept
Let's do this:
[tex]\begin{gathered} 21x+45y=-6 \\ 45y=-21x-6 \\ y=-\frac{21x}{45}-\frac{6}{45} \\ y=-\frac{21}{45}x-\frac{6}{45} \end{gathered}[/tex]So,

Yes; when the height is doubled, the area is also doubled (option D)
Explanation:width of the billboard = 44 ft
height of the billboard = 20 ft
the rent per square ft = $15
for a billboard twice as tall, the advertiser has to pay $26,400
We need to find the area of the billboard = width × height
Area = 44 × 20
Area of the billboard = 880 ft²
The rent for the whole area of the billboard = $15 × 880
The rent for the whole area of the billboard = $13,200
when the height is doubled = 2(height)
new height = 2(20) = 40 ft
The new area = 44 × 40 = 1760 ft²
The rent for the new area of the billboard = $15 × 1760
The rent for the new area of the billboard = $26400
The result in our calculation is the same as the amount the advertiser payed.
new height = 2(old height)
new area = 2(old area)
26400 = 2(13200)
We can conclude: it is reasonable
Yes; when the height is doubled, the area is also doubled (option D)

9.7 x 10^5
4.85 x 10^10
4.85 x 10^5
Answer:
4.85 x 10^5
Step-by-step explanation:
First you want to find 5.6 x 10^5 into simplified form, which is 560000.
Then, you want to find 4.1 x 10^5 into simplified form, which is 410000.
Then you can add these numbers together to get 970000.
970000 into scientific notation is 9.7 x 10^5.
CORRECTION:
Answer should be based off of the AVERAGE viewers, not total.
Average viewers is 485000
485000 in scientific notation is 4.85 x 10^5
The average number of viewers over the two weeks are 4.85 x 10^5
A tv show had 5.6 x 10^5 viewers in the first week
and 4.1 x 10^5 viewers in the second week.
What is an average number:
This is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers.
To find the average number of viewers over the two weeks
Remove the decimal point.
5.6 x 10^5 write like this 560000
Similarly, 4.1 x 10^5 write like this 410000
Now, Solving the question
Therefore, the average will be
560000 + 410000
= 970000/2
=485000
=4.85 X 10^5
and 4.85 x 10^5
Thus , the average number of viewers over the two week 4.85 x 10^5

1.Using geometry vocabulary, describea sequence of transformation that maps p onto figure q.2. write transformation mapping rule for the sequence you describe in part (a)P:(-1,2) (-1,4) (-4,2)(-4,4)Q:(2,-2) (2,-5) (4,-2) (4,-5)
First, we transform the coordinates of the vertices of P 270° anticlockwise.
The 270° anticlockwise transformation rule, T, is defined as:
[tex]T\colon(x,y)\to(y,-x)_{}[/tex]Therefore,
[tex]T(-1,2)=(2,1)[/tex][tex]\begin{gathered} T(-1,4)=(4,1) \\ T(-4,2)=(2,4) \\ T(-4,4)=(4,4) \end{gathered}[/tex]Let the resultant shape be named P'
Hence,
P': (2,1), (4,1) (2,4) (4,4)
Next
We translate the resultant shape downwards by 6 units.
The transformation rule, S, for moving downwards by 6 units is given by:
[tex]S\colon(x,y)\to(x,y-6)_{}[/tex]Therefore,
[tex]S(2,1)=(2,1-6)=(2,-5)[/tex][tex]\begin{gathered} S(4,1)=(4,1-6)=(4,-5) \\ S(2,4)=(2,4-6)=(2,-2) \\ S(4,4)=(4,4-6)=(4,-2) \end{gathered}[/tex]Hence, the image of S on P' is : (2,-2) (2,-5) (4,-2) (4,-5)
This is illustrated by the image below
