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
5 hours + 3 hours = 8 hours
8x = $40. Divide each side by 8.
x = $6.
You earn $6 / hour
2,250 m from his starting point.
Just turn 3.5 into 3500.
Then subtract 3500 by 1250. And the tiger ran 2250 m.
Answer B …… if im not wrong
True statements:
a) x + y = y + x ⇒ commutative property of addition
b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication
d) (x + y) + z = x + (y + z) ⇒ associative property of addition
False statements:
c) x - y = y - x should be: x - y = - y + x
e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
