Answer:
3/5
Step-by-step explanation:
It is 3/5 because you can divide by 10 on the top and bottom. 30/50=3/5
32/a = a/2
a^2 = 64
a = 8
b^2 = 8^2 + 2^2
b^2 = 64 + 4
b^2 = 68
b = 2√17
answer is the first option
a = 8, b = 2√17
Answer:

Step-by-step explanation:
In this problem we have a exponential equation of the form

where
y is the population of the city
x is the number of years
a is the initial value or y-intercept
b is the base
r is the rate of growth
b=(1+r)
we have

substitute

For x=17 years
substitute the value of x in the exponential equation and solve for y
