Answer:
o(-2,-1)
Step-by-step explanation:
Let point A be initial point and A' be terminal point.
A(-7,3), A'(x,y) and V=(5,-4)
V=(Xf-Xi,Yf-Yi)
(5,-4)=(x-(-7),y-3)
(5,-4)=(x+7,y-3)
5=x+7. -4=y-3
5-7=x. -4+3=y
x=-2. y=-1
A'=(-2,-1)
The coordinates of A'(-2, -1).
What is Translation?Translation is the act of moving a shape or a figure from one location to another. A figure can move in translation up, down, right, left, or anywhere else in the coordinate system. Only the object's position changes during translation; its size stays the same.
Given:
point A(-7, 3)
and vector, V =(5, -4).
So, V=([tex]X_f-X_i,Y_f-Y_i[/tex])
Where X(final) = ?, Y(Final)= ?
So, (5,-4)=(x-(-7),y-3)
(5,-4)=(x+7,y-3)
On comparing the coordinates
5=x+7 and -4=y-3
x= 2 and y = -1
Hence, the coordinates of A'(-2, -1)

Sam the Hummingbird flies at a rate of 2 yards per minute, as modeled by the equation y = 2x. She
increases her rate by 2 yards per minute. Plot two ordered pairs showing the distances she will fly at 1
minutes and 2 minutes, respectively, at her new rate.
Sometimes she may move backwards.
Answer:
See attachment for plot
Step-by-step explanation:
Given
[tex]y =2x[/tex]
[tex]R =+2[/tex] --- increment in the rate
First, we need to model the new rate
A linear equation is:
[tex]y = mx + b[/tex]
Where
[tex]m = rate[/tex]
Compare [tex]y =2x[/tex] and [tex]y = mx + b[/tex]. we have:
[tex]m =2[/tex]
The above represents the previous rate.
The new rate:
[tex]R =+2[/tex]
Rewrite as:
[tex]R = m+2[/tex]
[tex]R = 2+2[/tex]
[tex]R = 4[/tex]
So, the model is:
[tex]y = Rx[/tex]
[tex]y = 4x[/tex]
The plot at 1 and 2 minutes
When [tex]x = 1[/tex]
[tex]y = 4x = 4 * 1 = 4[/tex]
When [tex]x = 2[/tex]
[tex]y = 4x = 4 * 2 = 8[/tex]
So, we have:
[tex](x_1,y_1) =(1,4)[/tex]
[tex](x_2,y_2) =(2,8)[/tex]
Whether she moves backwards or forward, the distance covered remains the same

How to find the perimeter of a rectangle ,when given the area of the rectangle?
Answer:
120 m
Step-by-step explanation:
Width - x
Length - 5x
x*5x = 500m²
5x² = 500 m²
x²= 500 ÷ 5
x²= 100
x = root 100
x = 10
Therefore width = 10
length 5*10 = 50
Perimeter = 2(l+w)
= 2(10 + 50)
=2*60
=120
A block of wood is 2.5 feet long, 0.5 feet wide, and 0.25 feet tall. It weighs 16.5 pounds.
To the nearest pound, what is its density in pound per cubic feet?
Answer:
Density = 52.8 pound per cubic feet.
Step-by-step explanation:
Given the following data;
Length = 2.5 feet
Width = 0.5 feet
Height = 0.25 feet
Mass = 16.5 pound
To find the density of the wood;
First of all, we would determine the volume of the wood.
Volume = length * width * height
Volume = 2.5 * 0.5 * 0.25
Volume = 0.3125 cubic feet
Next, we find the density;
Mathematically, density is given by the formula;
Density = mass/volume
Substituting into the formula, we have;
Density = 16.5/0.3125
Density = 52.8 pound per cubic feet.

1. What is the surface area of the composite figure? Show ALL your work.
2. What is the volume of the composite figure? Show ALL your work.
Answer:
1. 144.4 m²
2. 120 m³
Step-by-step explanation:
The figure is composed of a triangular prism and a rectangular prism
1. Surface area of the composite figure = (surface area of the triangular prism - area of the face joining the rectangular prism) + (surface area of the rectangular prism - the face joining the triangular prism)
✔️Surface area of the triangular prism = bh + (s1 + s2 + s3)*L
b = 5 m
h = 2 m
s1 = 3.2 m
s2 = 3.2 m
s3 = 5 m
L = 6 m
Plug in the values
Surface area of triangular prism = 5*2 + (3.2 + 3.2 + 5)*6
= 10 + (11.4)*6
= 78.4 m²
✔️Area of rectangular prism = 2(LW + LH + WH)
L = 6 m
W = 5 m
H = 3 m
Plug in the values
Area of rectangular prism = 2(6*5 + 6*3 + 5*3)
= 126 m²
✔️Area of the face joining both figures = L*W
L = 6 m
W = 5 m
Area = 6*5 = 30 m²
✅Surface area of the composite figure = (78.4 - 30) + (126 - 30)
= 48.4 + 96
= 144.4 m²
2. Volume of composite figure = volume of triangular prism + volume of rectangular prism
= ½*a*c*h + L*W*H
a = 2 m
c = 5 m
h = 6 m
L = 6 m
W = 5 m
H = 3 m
Plug in the values
Volume = ½*2*5*6 + 6*5*3
Volume = 30 + 90 = 120 m³

H -13.5°, -3.2°, 0°, 17°
1 -13.5°, 0°, -3.2°, 17°
Answer:
H
Step-by-step explanation:
When the absolute value is bigger with a (-) negative sign, it means that it is the smallest. Since -13.5 has the greatest absolute value with a negative sign, then -3.2 is smaller than 0, the answer is H.

We can use the Pythagorean theorem to solve, where:
CT² = CP² + PT²
Thus:
CT² = 5² + 7²
CT² = 74
CT = √74 = 8.60
To solve for x, we must subtract the radius from CT to solve:
x = CT - 5
8.6 - 5 = 3.6

Please help i need the MAD what ever that means
Answer:
what is the MAD??????????
Step-by-step explanation:
Answer:
Answer depends on the data (not provided in your question)
Step-by-step explanation:
MAD stands for mean absolute deviation. The definition gives clues as to how to find it.
Deviation refers to how far a number is from the mean (average) of the data
Example: For the data -12, 4, 12, 16, the mean of the data is (-12+4+12+16)/4 = 5.
Data Absolute Deviation from mean
-12 |-12 - 5| = 17
4 |4 - 5| = 1
12 |12 - 5| = 7
16 |16 - 5| = 11
Mean Absolute Deviation (MAD)
(17 + 1 + 7 + 11) / 4 = 9

Juliette won her 400m race in a time of 1:01.71. If she ran the 1500m at the same rate,
approximately how fast would she run the race?
Answer:
230.77 seconds or about 3.85 minutes (2 minutes 50.4 seconds)
Step-by-step explanation:
First I will convert the minutes into seconds to make this a little easier.
1:01.71 would just be 61.71 seconds
400/61.71 is her speed for the first race. (speed is distance/time)
That is approximately 6.5 meters per second
time is distance/speed
1500/6.5= 230.769...
I do not know what you need to round to, but Juliette would take 230.769 seconds to run the 1500 meter race.

Qadir has $400.56 in his Friendly Debit card checking account. He uses the card to pay $450.50 to fix his furnace. Four days later, he deposits $150.00 into his checking account. How much money will Qadir have left in his account when the money is taken out to pay for the repair?
Answer:
$-69.94
Step-by-step explanation:
Amount left after the withdrawal to fix the furnace = $400.56 - $450.50 = $-49.94
He has a negative balance for 4 days. this would attract a 5 dollar fee per day. the total fee would be $20 ( 5 x 4)

a planter is shaped like a right rectangular prism its height, h is 5 4/5 inches. The length, L is 14 1/2 inches ,and its width, W is 3 1/2 inches. When determining of the planter, which statements are correct
Answer:
There appears to be some part of the question missing. Assuming it asks about the volume, the volume is:
Step-by-step explanation:
The volume of a right rectangular prism may be calculated using the formula:
whl, where w is width, h is height and l is length.
In this case it is hlw or (5.8*14.5*3.5) = 294.35 cubic inches.
Answer: 8 ft
Step-by-step explanation:To find the correct answer, use the formula, V=l×w×h. Substitute 48 for the volume, 2 for width, and 3 for height. Then, use a related division equation to find the length.
48 = l × 2 × 3
48 = l × 6, so 48 ÷ 6 = l
8 = l
The length of the planter box is 8 feet.
