Answer:

Step-by-step explanation:
we know that
In this problem we have a exponential function of the form

where
x ----> is the number of years since 2009
y ----> is the population of bears
a ----> is the initial value
b ---> is the base
step 1
Find the value of a
For x=0 (year 2009)
y=1,570 bears
substitute


so

step 2
Find the value of b
For x=1 (year 2010)
y=1,884 bears
substitute



The exponential function is equal to

step 3
How many bears will there be in 2018?
2018-2009=9 years
so
For x=9 years
substitute in the equation


I think the answer is B I got this right but it was for a completed grade so i’m not sure
Answer:
a= 52
Step-by-step explanation:
82 + (x+60) + (x+54) = 180
82 + 2x + 114 = 180
2x + 196 = 180
2x = -16
x = -8
plug in -8 in x +60
-8 + 60 = 52
a = 52
Answer:
336miles
Step-by-step explanation:
Given parameters:
Distance covered by the bus = 336miles
Time taken = 6hrs
Unknown:
How far the bus traveled = ?
Solution:
How far the bus traveled is the distance covered by the bus during the time duration specified.
From the problem, we can see that the bus traveled 336miles in 6 hours.
Therefore, the bus traveled 336miles.
