Answer:
Only first two are exponential growth function and last three functions are exponential decay functions.
Step-by-step explanation:
We need to describe exponential growth or decay for the given functions.
The standard exponential function equation is
Where a is the initial value and b is the growth factor.
Note: If value of b > 1, it would be an exponential growth and if b < 1, it would be an exponential decay.
Value of b is 1.008 > 1, therefor it's an exponential growth function.
y=250(1+0.004)^t, also have b>1 therefor it's an exponential growth function.
All other functions has b values less than 1, therefore only first two are exponential growth function and last three functions are exponential decay functions.
Answer:
C
Step-by-step explanation:
Answer
Circumference of the track used = 194.68 yards = 194.7 yards to 1 decimal place.
Explanation
The circumference of a circle is given as
Circumference = πD
where
π = pi = 3.14
D = Diameter = 62 yards
Circumference = πD
Circumference = 3.14 × 62 = 194.68 yards = 194.7 yards
Hope this Helps!!!
