Answer:
D.) 30ft
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Since x is squared, that's a non-linear equation because it's the only answer that, when graphed, doesn't form a straight line
Given the trigonometry expression:
sin 3x = sin(2x+x),
In trigonometry identity;
The expression above will then become;
Recall that sin^2x + cos^x = 1, hence;
This shows that

Answer:
- decay
- decay
- growth
Step-by-step explanation:
If the base of a positive exponential is greater than 1, the function is a growth function. If it is less than 1, the function decays.
Remember that a^-1 = 1/a, so a negative exponential can be transformed to a positive one.
__
1. y = 2(11/5)^-x = 2(5/11)^x . . . . 5/11 < 1, so decay
2. y = e^(-2x) = (1/e^2)^x . . . . 1/e^2 < 1, so decay
3. y = 1/4e^x . . . . e > 1, so growth
_____
e ≈ 2.71828 . . . an irrational number
