Answer: 1 over 2

Step-by-step explanation: if you take the coordinates of the pre-image, letter A. which is (2,6) and the coordinates of the transformed image A’ which is (1,3) and only use the first number of the coordinates. You would put the number of of the pre-image as the denominator and the number of the transformed image as the numerator. And It would become 1/2.

Answer:

Step-by-step explanation:

(-1)³·(-1)² = (-1)·(1) = -1

Alternatively,

(-1)³·(-1)² = (-1)³⁺² = (-1)⁵ = -1

A mobile base station (BS) in an urban environment has a power measurement of 8µW at 225m. Assuming the propagation follows an i

nata0808 [166]

Answer:

The reasonable value = 2.96 × 10^(-1) µW

Step-by-step explanation:

* Lets explain how to solve the problem

- A mobile base station in an urban environment has a power

measurement of 8 µW at 225 m

- The propagation follows an inverse cube power law

- We need to find the reasonable value to assume at a distance

678 m from the base station

∵ The propagation follows an inverse cube power law

- The power would have been decreased by a factor 1/n³

times the power as a distance increasing

∵ n = the ratio between the distances

∵ The distance are 675 m and 225

∴ n = 675/225 = 3

∴ 1/n³ = 1/3³ = 1/27

- The reasonable value is the product of the power measurement of

8 µW and 1/27

∴ The reasonable value = 8 × 1/27 = 8/27 µW = 0.296296

∴ The reasonable value = 2.96 × 10^(-1) µW

In △ABC, G is the centroid. If CG=12 find CD.

VladimirAG [237]

Answer:

CD = 24

Step-by-step explanation:

If G is the centroid, then CG = GD. (12 = 12)

Since CD is CG and GD combined, we would just add these two numbers to find the total length of CD.

CG + GD = CD

12 + 12 = 24
