look at the second number, the first 2 is -2 which is wrong since it should be +2
3rd option is not because if x=-2, then y=1
answer is D


3rd attachment
2nd: f(x)=60*1.15^x
3rd: no xint
6th: after 7.86 years value tripples
7th maybe: after 8 years value is 183.51, not exatly 184.00


4th attachment
nth score is
f(n)=57+4(n-1)
9th is
f(9)=57+4(9-1)
57+32=89
answer is C 89

Find the measure of angle A
Westkost [7]

Answer:

35 degrees

Step-by-step explanation:

Sum of angles inside a triangle is 180 degrees.

Right angle is 90 degrees.

180 = 90 + (x + 46) + (x + 66) = 2x + 202

x = -11

A = x + 46 = -11 + 46 = 35

What is the measure of ∠R ?
Zinaida [17]
Using the Law of Sines  (sina/A=sinb/B=sinc/C for any triangle)

sinR/30=sin96/54

sinR=30sin96/54

R=arcsin(30sin96/54)°

R≈33.5°  (to nearest tenth of a degree)
