R(3, 8) is dilated by a factor of 5, centered at (2, 10). Write the coordinates of R’.

The coordinates of R' are .

Step-by-step explanation:

According to Linear Algebra, dilation consist in expanding a given vector with  respect to one of its endpoints by a scalar. That is:

(Eq. 1)

Where:

- Original location with respect to origin, dimensionless.

- Point of reference with respect to origin, dimensionless.

- Dilation factor, dimensionless.

- Dilated point with respect to origin, dimensionless.

If we know that , and , then the dilated point is:

The coordinates of R' are .

two data sets with the same median will not have the same varaibility

step-by-step explanation:

you have 6 equal triangles, find the area of one of them (b*h/2) and multiply by 6

(8*4: 2)*6 =

32 cm² is your answer
