Answer:
Option C is correct.
Step-by-step explanation:
An exponential function is of the form: ....[1] where a is the initial value, x is any real number and b is the growth factor
Also, the b value (growth factor) has been replaced either by (1 + r) or by (1 - r).
Then, the growth "rate" (r) is determined as b = 1 + r.
and the decay "rate" (r) is determined as b = 1 - r
- If b> 1, then it is exponential growth function.
- if 0<b< 1. then it is exponential decay function.
Also, b = 1+ 4
Given the equation:
On comparing given equation with [1] we get;
a = 50 and b = 1.15
Since, b = 1.15 > 1
Therefore, the given equation represents the exponential growth.
(A)
Yes, this equation represents the exponential growth.
(B)
Initial value (a) = 50
(C)
Here growth factor, b = 1.15
and
1+ r = 1.15.

She can drive 558 miles with 18 gallons of fuel.
Step-by-step explanation:
Given,
Distance traveled with 5 gallons = 155 miles
Distance traveled with 1 gallon =
Total fuel hold by tank = 18 gallons
Total distance = Distance traveled with 1 gallon * Total fuel hold by tank
Total distance =
Total distance = 558 miles
She can drive 558 miles with 18 gallons of fuel.
