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
one way is to factor the expressions
(a)
(1.2 + (5.35 ×
))
= (1.2 + 53.5)
= 54.7 × = 5.47 ×
×
= 5.47 ×
(b)
((6.91 ×
) + 2.4)
= (69.1 + 2.4)
= 71.5 × = 7.15 ×
×
= 7.15 ×
(c)
((9.7 ×
) + 8.3)
= (97 + 8.3)
= 105.3 × = 1.053 ×
×
= 1.053 ×
(d)
((3.67 ×
) - 1.6)
= (36.7 - 1.6)
= 35.1 × = 3.51 ×
×
= 3.51 ×
(e)
((8.41 ×
) - 7.9)
= (84.1 - 7.9 )
= 76.2 × = 7.62 ×
×
= 7.62 ×
(f)
((1.33 ×
) - 4.9 )
= (13.3 - 4.9) = 8.4 ×
