Answer:
225 units squaredStep-by-step explanation:
Lets find the distance (the side length of the square)
D=sqrt((x2-x1)^(2)+(y2-y1)^(2))
plug in the coordinates:
D=sqrt((-5-(-5))^(2)+(12-(-3))^(2))
D=sqrt(0^(2)+15^(2))
D=sqrt(15^(2))
D=15
Area of a square is side length squared
A=s^2
A=15^2
A=225 units squared

Bag A contains 3 white marbles and 2 red marbles. Bag B contains 6 white marbles and 3 red marbles.A person draws one marble from each bag.Find the probability that both marbles are white.
Answer:
There is a 9 out of 14 chance that the marble will be white or there is a 3 out of 5 chance along with a 6 out of 9 chance.
Step-by-step explanation:
Since there's a total of 14 marbles from both bags and there are a possible 9 white marbles, it would be a total of 9 out of 14, or it would be separate and be a 3 out of 5 chance with a 6 out of 9 chance.

Find the area of the shape below
Answer:
32 units^2
Step-by-step explanation:
This is a trapezoid
The area of a trapezoid is found by
A = 1/2 (b1+b2) h
A = 1/2 ( 4+12) *4
A = 1/2 (16) *4
A =32
Answer:
I think the answer is 32.!
Step-by-step explanation:
Anyone please correct me if I'm wrong.
I would divide the 12 into 3 to get 4 for the 3 parts.
I will start with the triangle on the left 4 times 4=16. Divide it 1/2, which you get 8.
On the triangle on the right is the same, so 8.
The middle is 4 times 4=16.
Last 8+8+16=32.
I think the answer is 32 units.!
On a coordinate plane, a line goes through points (negative 3, negative 3) and (0, 3). What is the slope of the line on the graph? 1 1/2 2 3
Answer:
2
Step-by-step explanation:
We can find the slope between two points by using
m= (y2-y1)/(x2-x1)
= (3 - -3)/(0 - -3)
= (3+3)/(0+3)
= 6/3
=2

Una fabrica produce 132 litros de yogurt diarios .Con 49 litros se llenan botellas de 0,25litros xada una y con el resto que queda en el deposito se llenan botellas de 0,5 litros ¿cuantas botellas de yogurt se llenan ?
Answer:
[tex]z = 362\,botellas[/tex]
Step-by-step explanation:
(This exercise has been presented in Spanish and for that reason explanation will be held in Spanish)
La cantidad de botellas de 0,25 litros que se llenan con 49 litros de yogurt es:
[tex]x = \frac{49\,L}{0.25\,\frac{L}{botella} }[/tex]
[tex]x = 196\,botellas[/tex]
La cantidad remanente de yogurt es:
[tex]V_{r} = 132\,litros - 49\,litros[/tex]
[tex]V_{r} = 83\,litros[/tex]
Ahora, la cantidad de botellas de 0,5 litros que se llenan con el volumen remanente es:
[tex]y = \frac{83\,litros}{0.5\,\frac{litros}{botella} }[/tex]
[tex]y = 166\,botellas[/tex]
Finalmente, el total de botellas a llenar es:
[tex]z = 196\,botellas + 166\,botellas[/tex]
[tex]z = 362\,botellas[/tex]

A prism is a three dimentional shape with the same ________ all the way through
Can anybody fill in the blank?
A prism is a three-dimensional shape with the same cross-section all the way through.
What is prism?A prism is a solid shape that is bound on all its sides by plane faces.
A prism is a type of three-dimensional (3D) shape with flat sides. It has two ends that are the same shape and size (and look like a 2D shape).It has the same cross-section all along the shape from end to end; that means if you cut through it you would see the same 2D shape as on either end.
Hence, a prism is a three-dimensional shape with the same cross-section all the way through.

How can you get 2 to the power of -3 from the fraction 1/8?
given that f(x)=2x+1, a) find f(2) b) find f -1(x) c) find f-1(7)
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = 2x + 1
(a)
To evaluate f(2) substitute x = 2 into f(x), that is
f(2) = 2(2) + 1 = 4 + 1 = 5
(b)
let y = f(x) and rearrange making x the subject
y = 2x + 1 ( subtract 1 from both sides )
y - 1 = 2x ( divide both sides by 2 )
[tex]\frac{y-1}{2}[/tex] = x
change y back into terms of x and x = [tex]f^{-1}[/tex] (x) , thus
[tex]f^{-1}[/tex] (x ) = [tex]\frac{x-1}{2}[/tex]
(c)
To evaluate the inverse function substitute x = 7, that is
[tex]f^{-1}[/tex] (7) = [tex]\frac{7-1}{2}[/tex] = [tex]\frac{6}{2}[/tex] = 3

Answer:
The figure is a composite shape.
Theres 1 triangle and 1 rectangle
The formula to find the area of the triangle is 1/2 x base x height
1/2 x 7 x 3 = 10.5 units^2
The formula to find the area of the rectangle is base x height
7 x 3 = 21 units^2
Then add up all the areas to find the area of the entire shape.
10.5 units^2 + 21 units^2 = 31.5 units^2

Step-by-step explanation:
I used Cramer's Rule to find y, since we can isolate and solve for individual variables using Cramer's Rule. Do that by finding the determinant of the matrix, |A|. The matrix A looks like this:
2 -2 1
-1 3 2
1 -4 -3
and we find the determinant of a 3x3 by expanding it. Do that by picking up the first 2 columns and throw them on at the end, like this:
2 -2 1 2 -2
-1 3 2 -1 3
1 -4 -3 1 -4
and find the determinant by multiplying along the 3 major axes and subtract from that the product of the 3 minor axes:
[(2*3*-3)+(-2*2*1)+(1*-1*-4)] - [(1*3*1)+(-4*2*2)+(-3*-1*-2)] which simplifies to
-18 - (-19) = 1
So the determinant of the matrix A is |A| = 1.
Now to find the determinant of Ay, we replace the y column with the solutions and so the same thing by expansion and then multiplying and subtracting:
2 -7 1 2 -7
-1 0 2 -1 0
1 1 -3 1 1
and find the determinant of y:
[(2*0*-3)+(-7*2*1)+(1*-1*1)] - [(1*0*1)+(1*2*2)+(-3*-1*-7)] which simplifies to
-15 - (-17) = 2
So the detminant of y is |Ay| = 2
We can solve for the variable now by dividing Ay by A:
2 / 1 = 2
So the solution for y = 2
