What is the scale factor for pre-image IJKH to image MNOL?

solniwko [45]

Answer:

Step-by-step explanation:

Given are two rectangles MNOL and IJKH

MNOL is the image and IJKH is the preimage.

OBviously similarity is preserved between these.

Hence sides will be proportional

i.e. l1/l2 = w1/w2 = Scale factor k

This can also be written as

Scale factor square = $k^2=\sqrt{ \frac{areaI}{area2} }$

Scale factor = square root of ratio of rectangle areas

Find ratio as

$\frac{375}{135} =\frac{25}{9}$

k = Scale factor = square root of the above fraction

= $\frac{5}{3}$

Is 3 to the negative 1 power times 3 to the negative 1 power equal to 3 to the 1 power?

iren2701 [21]

To make the exponent positive, make a fraction. 1/3 * 1/3. This is 0.1 repeating. 3^1 is 3. So the answer is no.
