Answer:
y = 1/5x
Step-by-step explanation:
Here, we have a direct relationship between the distance from lightning and the time it takes to hear thunder
Let the distance from lightning be y and the time it takes to hear thunder be x
If k is the proportionality constant, then;
y = kx
Now, let’s calculate k , given x 10 seconds and y = 2 miles
2 = 10k
k = 2/10 = 1/5
So the equation for the given situation is;
y = 1/5x

Given:
f(x) = 620e^7.8x
The standard equation for an exponential function is f(x) = Aoe^bx
where Ao is the initial amount
b is the growth factor
so, in this case, the initial amount is 620 and the growth factor is 7.8
