Answer:
B. y = 10(2)^x
Step-by-step explanation:
y = ab^x
to find "b" divide the function at x = 3 by the function at x = 2
80 = ab^3
——————
40 = ab^2
This results in
2 = b
to find "a" plug pickany value of x
using x = 2
40 = a(2²)
40 = a(4)
a = 10
With a = 10 and b = 2 the exponential function y = ab^x is
y = 10(2)^x

Answer
3.7/ €3.7
Answer:
23
m/s
Step-by-step explanation:
We can change the km to m first. 1km = 1000m.
84km/h = 84 000m/h
Then, we can change the h to s. 1h = 3600s.
84 000m/h = 23
m/s
