A rectangle with vertices A (4,8), B (16, 8), C (16, 20) and D (4, 20) is dilated about the origin as the center. Find the vertices of the image if the scale
factor is 1/4.
O A' (1, 2), B' (4,8), C (4,5) and D' (1,5)
OA (1,2), B' (4,2), C (4, 5) and D' (1,5)
O A (1, 2), B' (4,2), C (4, 5) and D' (4, 10)
OA (2, 2), B' (4,2), C (4, 5) and D' (1,5)

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
