Travis Scott and Trippie Redd decided to collab. The next day, they each told ten friends that their new EP was
dropping. These ten people loved it so much, that they
EACH told ten of their friends the day after, who EACH
told ten of their friends the next day, and so on.
This situation can be modeled using the equation: y = 2(10)
After what day would 1000 people hear about the new EP
dropping?

15

step-by-step explanation:

1) is right

step-by-step explanation:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
