Answer:
It's y = (5)(0.2)^x
_____________
Step-by-step explanation:
Exponential functions have a standard form of ab^x
Where a is the starting value, and b is the exponential growth or decay.
Because the numbers are getting smaller and smaller, it is a decay so b must be less than one.
We can eliminate the first choice because when x is 1, y is 1. If this where the equation we would get (5) (1/2) ^ 1 = 5 × 1/2 = 2.5 ≠ 1.
So the answer must be the second choice.
The number would be 18.
Half of 18 = 9
Two thirds of 18 = 12
9 + 12 = 21
Answer:
70 seconds
I think that's what you are looking for?
99 degrees warmer because since -27 a negative number you have to add 27 to get to 0 so Alaska is then 72 degrees which is a positive number so you add 72+27 and get 99
Has to be a table, you need numbers for the others
