Answer:
The first one : decay
The second one : growth
When the argument of the exponential expression is bigger that 1 then it represents a growth
When it's less than 1 and above 0 then it's a decay
Answer:
Step-by-step explanation:
let they travel the distance between them alone
d = common distance traveled by both motorcycle and car = 540 miles
= time taken by motorcycle to travel distance between them
= speed of the motorcycle = 48 mph
time taken by motorcycle to travel distance between them is given as
= d/
=540/48
= 11.25 h
= time taken by car to travel distance "d" =11.25 - 2.25 = 9 h
= speed of the motorcycle
speed of motorcycle is given as
= d/
= 540/9
= 60 mph
when the car and motorcycle move towards each other, the relative speed is given as
v =
+
v = 60 + 48
v = 108 mph
t = time taken to meet
Time taken to meet is given as
t = d/v
t = 540/108
t = 5 h
Answer:
we CANNOT DIVIDE 3 with 6.
Step-by-step explanation:
Here,as given in the question:
Starting value = 6
Constant ratio = 1/3
Now, exponential function is obtained by the product of starting value and the constant ratio repeatedly.
⇒ f(x) = (Starting value) x (ratio)... x times
Now, we CANNOT DIVIDE 3 with 6 as it is in the power of x.
Hence,
and
