An image of two concentric circles is shown with r2 = 6 and r1 = 2:
AysviL [449]

The radius of the Outer circle (with r₂) is 6 and the radius of the inner circle (with r₁) is 2. When objects are similar, they have a proportional relationship. If we take the outer circle and squeeze by one third, we get a radius of 6 x 1/3 = 2. On the other hand, if we start with the inner circle and stretch it by 3, we get a radius of 2 x 3 = 6.


Thus, to make r₂ similar, we use a scale factor of 1/3. The third choice is best.

If y = 8 when x<br> 8 when x = 3, find y when x = 45.
Zarrin [17]

Answer:

y = 120

Step-by-step explanation:

y = kx ur finding k

8 = k 3 get k alone by dividing both sides by 3 --> 8/3 = k

k = 8/3

Y = 8/3 45 now your finding Y when x is 45

Y = 120

to make sure do 120 = 8/3 45 should equal the same
