Y=kx is the direct variation equation
First plug in the x, y values given to find K
18=k(5)
18/5=k
3.6 = k
Use the k and write a new equation.
y=3.6x
Plug in the x value to solve for y.
y = 3.6(11)
y= 39.6

Answer:
Step-by-step explanation:
Given : The initial value is 175 and the rate of decay is 20%
To find : Exponential functions represents a given situation.
Solution :
The general form of exponential function when decay is there
Where,
y is the final amount
a is the initial value
r is the rate of decay
t is the time
(1-r) is the decay factor
According to given situation,
Initial value a=175
Decay rate is 20%
r=20%=0.2
Substitute the value,
