42. A duplicating machine enlarges a picture 20%.
If that enlarger is used 4 times, about how many
times as large as the original picture will the
final picture be?
A 0.8
B 2.1
C 4.8
D 5

2.1

Step-by-step explanation:

1 x 0.2 = 0.2

1.2 x 0.2 = 0.24

1.44 x 0.2 = 0.288

1.728 x 0.2 = .3456

1.728 + 0.3456 = about 2

Please mark me brainliest

it would be a on edgenuit y

the diagram below is your final answer

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
