I wanna say B cause on my calc 1/3x is less steep than g(x) but idk good luck <3
Let the distance of Jill form the base of the tower be x, then tan 40 = 100/x
x = 100/tan 40 = 100/0.8391 = 119.18 meters
Let the height of the tower from the level of the top of Jill's apartment be y, then tan 30 = y/119.18
y = 119.18 x tan 30 = 68.8 meters
Therefore, the height of Jill's apartment is 100 - 68.8 = 31.2 meters
We have to find the expansion of
We will use binomial expansion to expand the given expression, which states that the expression is expanded as :
Now expanding we get,
So, the variables are , , ,
Answer:
4, 3, 12,
Step-by-step explanation:
6.89(1.21) = 8.3369 rounds to 8.34 <==
or u could also do it this way...
6.89 + 0.21(6.89) = 6.89 + 1.4469 = 8.3369 rounds to 8.34 <==
