The appropriate formula is C = 2*pi*r.
Here, C = 2*pi*(50 units) = 100*pi units (answer)
This is an exponential equation that can be represented by the following:
f(x) = a(b)^x
In this case...
25143 = a(0.66)^3
25143 is the population after 3 hours.
3 is the amount of time in hours.
0.66 represents the percent of the population remaining after each hour (66% as there is a 34% decline each hour).
We must solve for a, which is the initial population.
First, simplify (0.66)^3 to 0.2874.
25143 = 0.2874a
Now divide both sides by 0.2874 to isolate a.
a = 87455
There were initially 87,455 people within the city. I wouldn't want to be in that place!

Answer:
Step-by-step explanation:
a). tan(75°) =
=
k =
k = 2.947
k = 2.95 cm
b). cos(52°) =
s =
s = 25.988
s ≈ 25.99 cm
c). sin(5°) =
=
q =
q = 184.727
q ≈ 184.73 cm
Answer:
Well the Regular would be 3,2 and the reflection would be 3,-2
Step-by-step explanation:
the regular is already plotted x comes before y that is why the order is like that the square the regular is in is +,+ the reflection is +,- showing why the order is like that hope this helps!
