RST is dilated about the origin,O, to creat R’S’T’. Point R is located at (3,9) and point R is located at (1.2, 3.6). Which scal

Answer:

The scale factor used is 0.4

Step-by-step explanation:

Given

$R = (3,9)$

$R' = (1.2, 3.6)$

Required

Determine the scale factor of RST

The question can be solved using scale factor formula

Scale factor is calculated as thus;

$Scale\ Factor = \frac{New\ Length}{Old\ Length}$

In this case; R' is the new length and R is the old length

$Scale\ Factor = \frac{R'}{R}$

Substitute the values of R and R'

$Scale\ Factor = \frac{(1.2,3.6)}{(3,9)}$

Factorize the denominator

$Scale\ Factor = \frac{(1.2,3.6)}{2.5(1.2,3.6)}$

$Scale\ Factor = \frac{1}{2.5}$

$Scale\ Factor = 0.4$

<em>Hence, the scale factor used is 0.4</em>

If UW=6x-35, UV=19, VW=4x-20 , what is UW

Anarel [89]

Since V is a point on the line UW, therefore:
the length of UV + the length of VW = the length of UW
19 + 4x - 20 = 6x - 35
19 - 20 + 35 = 6x - 4x
34 = 2x
x = 34/2 = 17

Based on this:
UW = 6x - 35 = 6(17) - 35 = 67 cm
UV = 19 cm
VW = 4x - 20 = 4(17) - 20 = 48 cm
