Throughout this activity, the scale factor, n, has been a positive value. However, a scale factor for dilations can also be negative. When a set of coordinates on a preimage is multiplied by -n instead of n, the coordinates of the image rotate about the center of dilation by 180°. Consider all the potential intervals of n in the table. Enter information in the table to indicate whether the scale factor produces an enlargement, a reduction, or no size change. Also indicate whether the image rotates 180° about the center of dilation. The first one has been done for you.

A fence will be built to enclose a 100-m by 70-m field. It will need a post at each corner and one every 5 m. How many posts are needed?

Answers

The answer is 68.

Field had shape of rectangle since has difference in length and width. The perimeter of rectangle can be expressed as:
P = 2 × (a + b)

If:
a = 100 m
b = 70 m
Then
P = 2 × (100 m + 70 m)
P = 2 × 170 m
P = 340 m.

If posts are on every 5 m, the number of needed posts is:
340 m ÷ 5 m = 68.
Thus, 68 posts are needed for the fence.

Given the points A(0, 0), B(e, f), C(0, e) and D(f, 0), determine if line segments AB and CD are parallel, perpendicular or neither. a.parallel
b.perpendicular
c.neither

Answers

The slope:
m = rise / run;
For the line segment AB:
m AB = (y 2 - y 1) /(x 2 - x 1) = ( f - 0 ) / ( e - 0 ) = f / e
For the line segment CD:
m CD = ( 0 - e ) / ( f - 0 ) = - e / f
m CD = - 1 / m AB
Answer:
The lines are B ) perpendicular

Answer:

b.perpendicular

Subtract these polynomials. (3x2 + 3x + 3) - (x2 + 2x + 3) =

A. 2x2 + x
B. 2x2 + 5x
C. 2x2 + 5x + 6
D. 2x2 + x + 6

Answers

Answer:

$2x^2+1x$

Step-by-step explanation:

Subtract these polynomials.

$(3x^2 + 3x + 3) - (x^2 + 2x + 3)$

To subtract, we multiply negative sign inside the second parenthesis

$3x^2 + 3x + 3-x^2 - 2x - 3$

To subtract the polynomials we combine like terms

$3x^2-x^2+ 3x- 2x+3-3$

$2x^2+1x$

3x^2 -x^2= 2x^2
3x-2x=x
3-3=0

The answer is A.

Lauren is building a tree house with her dad. The dimensions of the floor are 9 feet by 6 feet. What is the area of the floor,measured in square yards?

Answers

6 square yards. L x W, gives you 54 but that's in feet. you have to convert it into square yards giving you 6 square yards

There are 3 feet in one yard, which means that the dimensions of the floor is 3 yards x 2 yards. In order to find the area, we must multiply the length by the width. Therefore the area of the floor is 6 square yards.
