Given:
The vertices of the rectangle ABCD are A(0,1), B(2,4), C(6,0), D(4,-3).
To find:
The area of the rectangle.
Solution:
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, we get
[tex]AB=\sqrt{(2-0)^2+(4-1)^2}[/tex]
[tex]AB=\sqrt{(2)^2+(3)^2}[/tex]
[tex]AB=\sqrt{4+9}[/tex]
[tex]AB=\sqrt{13}[/tex]
Similarly,
[tex]BC=\sqrt{(6-2)^2+(0-4)^2}[/tex]
[tex]BC=\sqrt{(4)^2+(-4)^2}[/tex]
[tex]BC=\sqrt{16+16}[/tex]
[tex]BC=\sqrt{32}[/tex]
[tex]BC=4\sqrt{2}[/tex]
Now, the length of the rectangle is [tex]AB=\sqrt{13}[/tex] and the width of the rectangle is [tex]BC=4\sqrt{2}[/tex]. So, the area of the rectangle is:
[tex]A=length \times width[/tex]
[tex]A=\sqrt{13}\times 4\sqrt{2}[/tex]
[tex]A=4\sqrt{26}[/tex]
[tex]A\approx 20[/tex]
Therefore, the area of the rectangle is 20 square units.

A square has a perimeter of 8g + 16. Which expression also represents the perimeter given the side length of the square?
Answers
Answer:
4(2g+4)
Step-by-step explanation:
8g+16
Since this expression represents the total perimeter, we need one side length. So we divide this by 4, because it's a square and all sides are of equal length.
8/4=2
16/4=4
One side is 2g+4. So multiply that equation by 4.
4(2g+4)
DOUBLE CHECK
4(2g+4)
8g+16

Answer:
1 < x
Step-by-step explanation:
We have to used same order of operations just as we would in an equation;
15 > -x + 16
=> First subtract 16 from each side
-1 > -x
=> To bring x to positive, divide each side by -1 (Since we are dividing by a negative value, the inequality sign will switch)
Therefore the answer is: 1 < x
Hope this helps!
Answer:
15>-x+16
-1>-x
1<x

Investment a starts with $1000 and increases its value by $80 each week. Investment b starts with $2000 and loses $50 of its value each week.After how many weeks will the two investments have the same value?
Answers
Answer:
33.3 weeks
Step-by-step explanation:
Let us represent number of weeks = w
Investment a starts with $1000 and increases its value by $80 each week.
$1000 + $80 × w
1000 + 80w
Investment b starts with $2000 and loses $50 of its value each week.
$2000 - $50 × w
2000 - 50w
After how many weeks will the two investments have the same value?
1000 + 80w = 2000 - 50w
Collect like terms
80w + 50w = 2000 - 1000
130w = 1000
w = 1000/30
w = 33.333333333 weeks
Approximately
After 33. 3 weeks, the Investment will have the same value

What are arithmetic operations?The most fundamental operations in arithmetic are addition, subtraction, multiplication, and division. However, arithmetic also includes more complex operations like manipulating percentages, square roots, exponentiation, logarithmic functions, and even trigonometric functions, which are analogous to logarithms. Other examples of more complex operations include exponentiation. Arithmetic expressions must be evaluated in accordance with the intended order of operations.
Given total amount Renee have = $60
Cost for entry in park = $25
The amount left with Renee = 60 - 25
The amount left with Renee = $35
now cost for each game is $3
total no. of games can be played in $35 = [tex]\frac{ The amount left with Renee}{ cost for each game}[/tex]
35/3 = 11.667
Hence we only count integer digits which is 11; so Renee can play 11 different games.

What is the area of the shaded sector?
Answers
Answer:900 square units
Step-by-step explanation:
The radius is 90 units. Then the area of the shaded sector will be 900π square units.
What is the area of the sector?Let r be the radius of the sector and θ be the angle subtended by the sector at the center. Then the area of the sector of the circle will be
A = (θ/360°) πr²
The circumference of circle T is 180π units. Then the radius of the circle is given as,
C = 180π
2πr = 180π
r = 90 units
Then the area of the sector is given as,
A = (40°/360°) π x 90²
A = 900π square units
The area of the shaded sector will be 900π square units.

The graph for the inequality given is graph 1.
What is an inequality?An inequality is a relation between two numbers or expressions that are not equal. It can show which of them is greater or smaller by using symbols like < or >. It can also be a statement of fact about the order relationship of quantities.
Given that an inequality, 2-(x+3) < 4 -2x, we need to determine its graph,
For the same solving the inequality,
2-(x+3) < 4 -2x
2-x-3 < 4 - 2x
Add x to both sides,
2-3 < 4-x
-1 < 4-x
Subtract 4
-1-4 > -x
x > 5
Since, the x is greater than 5 so the graph will be the numbers that greater than 5,
Hence, the graph is 1.

Step-by-step explanation:
Given data
Length of ladder= 50ft
Angle= 75°
We want to find the Height of the wall
Applying the SOH CAH TOA
sin ∅= opposite/hypotenus
sin 75= opposite/ 50
0.965= opposite/ 50
opposite=0.965*50
opposite= 48.25ft
Hence the height of the wall ] is 48.25ft
