Answer:
<u>Easy way to distinguish:</u>
- Linear function forms a AP and exponential function forms a GP
<u>We see f(x) is series of:</u>
- This is a AP with common difference of 6 and the first term of 8
<u>g(x) is series of:</u>
- 4, 12, 36, 108, 324
- This is a GP with common ratio of 3 and the first term of 4
1. <u>g(x) is exponential function:</u>
2. <u>f(x) is linear function:</u>
Answer:
x ≈ 19.7
Step-by-step explanation:
Using the sine ratio in the right triangle.
sin66° = 
= 
( multiply both sides by x )
x × sin66° = 18 ( divide both sides by sin66° )
x = 
≈ 19.7 ( to the nearest tenth )
Answer:
1/a^n
Step-by-step explanation:
To simplify, you remove the negative by "flipping" what side it is on.
a^-n/1 -> 1/a^n
Factor 4 out of 4x+20.
4(x+5)
