Mathematics

The answer would be the first choice. When you reflect a shape across the x-axis, the y coordinates of every points/vertices become of the opposite of what they usually were.
For example, the y coordinate in (1, -5) {{-5 being the y coordinate) once reflected upon the x axis would be (1, 5).

On the other hand, if the y coordinate were positive it would become negative.

23/147 yd × 3/14 after reducing them by a factor of 2/147 what are the original dimensions of the playground in yards? Write you
DENIUS [597]

Answer:

So the dimensions are 11 1/2 yds × 15 3/4 { 11 whole number 1 by 2 yards multiplied by 15 whole number 3 by 4}

Step-by-step explanation:

Here multiplicative property will be used .

a*<u>1/a</u>= 1

1* <u>a/1</u>= a   ( reciprocal)

23/147 yd × 3/14 will be multiplied with the reciprocal of the factor 2/147 to

get the original number.

23/147 yd*147/2 × 3/14*147/2

23/2 yds  × 441/28

11 1/2 yds × 15 3/4

So the dimensions are 11 1/2 yds × 15 3/4  11 whole number 1 by 2  multiplied by 15 whole number 3 by 4.

Which of the following is the third term of the expansion (a + b)^n ?
Luba_88 [7]

Answer:

  C(n, 2)a^(n-2)b^2

Step-by-step explanation:

Generally, the expansion is written in decreasing powers of "a", so the first few terms would have variable constellations that look like ...

  a^n, a^(n-1)b, a^(n-2)b^2, ...

The coefficients would be (in order), C(n, k) for k increasing from 0, so the coefficient of the 3rd term would be C(n, 2).
