Points E(-1, -2) and F(4, -2) are the vertices of a square. Give the coordinates of three possible pairs of points for the other

two vertices.
I already got the pairs:
(-1, 3), (4, 3)
(-1, -7), (4, -7)

I have no idea what to do for the third set of points.

The vertices of a square are its endpoints

The coordinates of the other pairs are: (-1, 3), (4, 3)  and (-1, -7), (4, -7)

The given parameters are:

\mathbf{E = (-1,-2)}

\mathbf{F = (4,-2)}

Calculate the distance EF

\mathbf{EF = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}}

So, we have:

\mathbf{EF = \sqrt{(-1 - 4)^2 + (-2 - -2)^2}}

\mathbf{EF = \sqrt{25}}

\mathbf{EF = 5}

Add 5 to the y-coordinates of E and F

\mathbf{C = (-1,-2+5)}

\mathbf{C = (-1,3)}

\mathbf{D = (4,-2+5)}

\mathbf{D = (4,3)}

Subtract 5 to the y-coordinates of E and F

\mathbf{C = (-1,-2-5)}

\mathbf{C = (-1,-7)}

\mathbf{D = (4,-2-5)}

\mathbf{D = (4,-7)}

Hence, the coordinates of the other pairs are: (-1, 3), (4, 3)  and (-1, -7), (4, -7)

There is no third pair

From a square piece of cardboard paper of area size 9 m2 , squares of the same size are cut off from each corner of the paper. T
levacccp [35]

Answer:

Max vol = 2 cubic metres

Step-by-step explanation:

Given that from a square piece of cardboard paper of area size 9 m2 , squares of the same size are cut off from each corner of the paper.

Side of the square = 3m

If squares are to be cut from the corners of the cardboard we have the dimensions of the box as

3-2x, 3-2x and x.

Hence x can never be greater than or equal to 1.5

V(x) = Volume = V(x) = x(3-2x)^2\\= 9x+4x^3-12x^2

We use derivative test to find the maxima

V'(x) = 9+12x^2-24x\\V"(x) = 24x-24\\

Equate I derivative to 0

9+12x^2-24x=0\\x=1/2,3/2

If x= 3/2 box will have 0 volume

So this is ignored

V"(1/2) <0

So maximum when x =1/2

Maximum volume

=9(1/2)+4(1/2)^3-12(1/2)^2\\=2 cubic metres

What two consecutive integers have a sum of 75?
marshall27 [118]

Answer:

37 and 38.

Step-by-step explanation:

Let the smaller integer be x.

Thus, the larger integer is (x+1) since it is consecutive.

x+(x+1)=75

2x+1=75

Subtract both sides by 1:

2x+1-1=75-1

2x=74

Divide both sides by 2:

\frac{2x}{2}=\frac{74}{2}

x=37

To find the other number, simply add 1 to 37 to get 38.
