Step-by-step explanation:
Blue is for physics........
To find the answer, we can first find the age of Rolando in four year:
17+4
=21
We can then proceed to find the current age of Marisa,which is 3/2 of Rolando’s age calculated above:
Let Marisa’s age be y.
3/2 y =21
y = 21 × 2/3
y = 42/3
y = 14
Therefore Marisa is currently 14 years old.
In three years, Marisa would be:
14+3
=17
Therefore, she will be 17 years old.
Hope it helps!
Answer:

Step-by-step explanation:
we know that
The equation of a exponential growth function is given by

where
P(t) is the population in Madison
t is the number of years
a is the initial value
b is the factor of growth
we have

substitute

I think 0.3 is less 7.85 because there is a 1 on the end that was is a 3 and if you round it would be 0
9 x 3 = 27
27/9=3
12 x 3= 36
36/3=12
