Dilate line f by a scale factor of 2 with the center of dilation at the origin to create line f'. Where are points A' and B' loc

ated after dilation, and how are lines f and f' related?
The locations of A' and B' are A' (0, 4) and B' (4, 0); lines f and f' are parallel.
The locations of A' and B' are A' (0, 2) and B' (2, 0); lines f and f' are the same line.
The locations of A' and B' are A' (0, 2) and B' (4, 0); lines f and f' intersect at point A.
The locations of A' and B' are A' (0, 4) and B' (2, 0); lines f and f' intersect at point B

Answer:

Option (1).

Step-by-step explanation:

Given question is incomplete: find the complete question in the attachment.

From the given figure, coordinates of the points A and B are (0, 2) and (2, 0) respectively.

Slope of line AB = \frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}

                      m_{1}=\frac{2-0}{0-2}=-1

When these points are dilated by a scale factor = 2, about the origin

Rule for the dilation → (x, y) → (kx, ky)

Where k = scale factor

Coordinates of the points A' and B' will be (0, 4) and (4, 0)

Slope of the line A'B' = \frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}

                             m_{2}=\frac{4-0}{0-4}=-1

Since m_{1}=m_{2} , both the lines AB and A'B' will be parallel.

Therefore, option (1) will be the answer.

Manufacture wants to enlarger it's floor area 1.5 times that of the current facility. The current facility is 260 ft by 140 ft.
Lady bird [3.3K]

Answer:

New dimensions of the floor is approximately 301.25 ft by 181.25 ft

Step-by-step explanation:

The question is incomplete. The complete question should be:

Manufacture wants to enlarger it's floor area 1.5 times that of the current facility. The current facility is 260 ft by 140 ft. The manufacture wants to increase each dimension the same amount. Write the dimensions of the new floor.

Given:

Length of floor = 260 ft

Width of floor = 140 ft

The floor area is increased 1.5 times.

To find the new dimensions of the floor.

Solution:

Original area of the floor = length\times width= 260\times 140=36400\ ft^2

New area = 1.5\times Original\ Area = 1.5\times 36,400=54,600\ ft^2

Let the length and width be increased by x ft.

Thus, new length = (260+x)\ ft

New width = (140+x)\ ft

Area of the new floor can be given as:

⇒ new\ length\times new\ width

⇒ (260+x)(140+x)

Multiplying using distribution.

⇒ x^2+260x+140x+36400

⇒ x^2+400x+36400

Thus we can equate this with new area to get the equation to find x

x^2+400x+36400=54600

subtracting both sides by 54600.

x^2+400x+36400-54600=54600-54600

x^2+400x+18200=0

Using quadratic formula:

For a quadratic equation ax^2+bx+c=0

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

For the equation x^2+400x-18200=0

x=\frac{-400\pm\sqrt{(400)^2-4(1)(-18200)}}{2(1)}

x=\frac{-400\pm\sqrt{232800)}}{2}

x=\frac{-400\pm482.49}{2}

x=\frac{-400+482.49}{2} \ and\ x= \frac{-400-482.49}{2}

∴ x\approx 41.25 \ and\ x\approx-441.25

Since length is being increased, so we take x\approx41.25

New dimensions are:

New length \approx 260\ ft + 41.25\ ft =301.25\ ft

New width \approx 140\ ft + 41.25\ ft =181.25\ ft
