What is the area of a rectangle with vertices at (0, −4), (−1, −3) , (2, 0), and (3, −1)? Enter your answer in the box. units²
Answer:
12
Step-by-step explanation:
Answer:
Area of the rectangle is [tex]6u^{2}[/tex]
How to find area of rectangle if the vertices are given:
Let the vertices be or the given vertices:
A [0,-4]
B [-1,-3]
C [2,0]
D [3,-1]
Area of rectangle is twice the area of triangle, i.e. if the area of rectangle is ABCD and area of triangle is ABC.
Area of triangle is given by determinant:
Area of triangle = 1/2 [x1, y1]
1/2 [x2, y2]
1/2 [x3, y3]
1/2 [x4,y4]
Putting all the values in this format we will get :
Area of triangle = 1/2 [0×-4]
[-1×-3]
[2×0]
Because we have assume 0 as x1 and -4 as y2
-1 as x2 and -3 as y2
2 as x3 and 0 as y3
By solving that equation we will get:
1/2[ −4 0 1]
[−3,1,1]
[0,−2,1]
=1/2(−4⋅(1⋅1+1⋅2)−0+1⋅(6−0))
=1/2|-6|= [tex]3u^{2}[/tex]
= -3=[tex]3u^{2}[/tex]
= [tex]6u^{2}[/tex]
In a two-dimensional plane, a triangle's area is the space it encloses. Known for having three sides and three vertices, a triangle is a closed shape. The sum of the spaces occupied by a triangle's three sides is known as its area. Half of the product of a triangle's base and height is the usual formula for calculating its area.The area that is included within the perimeter of a flat object or figure is generally considered to be the definition of the word "area." The square units used for measuring are square meters as the standard unit (m2). There are already established formulas for calculating the area of squares, rectangles, circles, triangles, etc.

PLEASE HELP ME OUT!!
Answer:
Hello!
Judging by the question you have provided I have come up with the correct solution:
y=25x+175
Step-by-step explanation:
The way I came up with the solution is by understanding how to write the correct equation using the correct variables in the correct places.
In the equation y=mx+b, the variable "b" will always be an independent variable.
The independent variable of Candace equation is "175 gallons". This is because this amount does not change throughout the entire equation.
Next, the variable "m" will always be a dependent variable.
The dependent variable of the Candace equation is "25 gallons". This is because this variable is effected by "x amount of hours".
So when you input these given variables in the correct places you get:
y=25x+175
Trevor found that a circle has a circumference of 15 ft. What is the diameter & radius of the circle? Write & solve an equation. Leave your answer as a decimal.
Answer: R = 2.38732415 D = 4.7746482927568605
Solve this equation for the indicated variable.5b + 12c=9 for b
Answer:
b = (9 - 12c)/5 OR b = 9/5 - 12c/5
Step-by-step explanation:
5b + 12c = 9
Subtract 12c from both sides.
5b = 9 - 12c
Divide both sides by 5.
b = (9 - 12c)/5.

A 4-card poker hand is dealt at random from a standard 52-card deck. What is the total number of possible hands
Answer:
Step-by-step explanation:
The first choice is 1 out of 52
The second choice is 1 out of 51 because 1 card went with the first choice
The third is 1 out of 50
The fourth is 1 out of 49
Number of hands = 52*51*50*49
Number of hands = 6497400
Divide 320 into 8 equal groups
Answer:
320 divided by 8 is 40. 40 times 8 is 320, so it works backwards.
When dividing 320 into 8 equal groups, each group would contain 40.
We have to divide 320 into 8 equal groups.
Performing the division as
8 | 320 | 40
320
-_______
0
So, 320 ÷ 8 = 40
Therefore, when dividing 320 into 8 equal groups, each group would contain 40.

What is the inverse of the function f(x)=-4x+2
Answer:
The inverse of f is [tex]f^{-1}[/tex] = (x -2)/4
Step-by-step explanation:
To find the inverse of f(x) = 4x + 2 , interchange the variables and solve for y.
Rewrite f(x) = 4x + 2 as x = 4y + 2 then solve for y
x -2 = 4y
(x - 2)/4 = y

Two arithmetic sequences A and B both begin with 30. Sequence A has common difference 9 and sequence B has common difference 4. What is the difference between the 51st term of A and the 51st term of B?
The n-th term of an arithmetic sequence with first term a and common difference d is
a + (n - 1) d
So, the 51st term of A is
30 + 9 (51 - 1) = 480
while the 51st term of B is
30 + 4 (51 - 1) = 230
The difference between them 480 - 230 = 250.

You used 5 cups of flour to bake 80 cookies. How many cups of flour do you need if you bake 144 cookies?
Answer:
9 cups
Step-by-step explanation:
We can write a ratio to solve
5 cups x cups
------------ = ----------------
80 cookies 144 cookies
Using cross products
5 * 144 = 80x
720 = 80x
Divide by 80
720/80 = 80x/80
9=x
Answer:
7 1/5 cups of flour to mae 144 cookies
Step-by-step explanation:
80/5 = 20 cookies per cup of flour
so 20x7 = 140 and then you still need four more so take the four and another cup of flour and divide the 20 by 4 then you get 5 thus you 7 and 1/5ths cups
Function or not a Function
Answer:
Function; Not a function
Step-by-step explanation:

Write the ordered pair in the second set (x, y): (1, 3), (1, 4), (2, 4) , (3, 2)
The first set in a function because no ordered pair has the same x value.
The second set in not a function because the x value is the same in two of the ordered pairs.
