First, we find x using the given equation:
x = 4 / sin(53)
x = 5
We also know that:
Cos(∅) = base / hypotenuse
Therefore,
cos(53°) = y / 5
Answer:
f^-1(x)=x/3+2/3
Step-by-step explanation:
Answer:
Step-by-step explanation:
A = Pe^rt
A = total
P = amount you start with
r = rate
t = time
Let's calculate the rate.
99000000 = 94000000e^r*6
Divide each side by 94m
99000000/94000000 = e^6r
Take the natural log of e of both sides.
ln(99000000/94000000) = 6r
Divide each side by 6.
(ln(99000000/94000000))/6 = r
Now we can find the population in 2005.
A = 94000000e^0.00863751131 * 12
A = 104265957
The population in 2005 is 104,265,957 people.
Set up a proportion.
27% = 0.27
81/0.27 = x/1
Multiply 1 to both sides:
x = (81 * 1)/0.27
Multiply:
x = 81/0.27
Divide:
x = 300
So they hope to sell 300 magazine subscriptions.
Answer:
The answer is 7.5.
Step-by-step explanation:
Since we're looking for half of 15, divide 15 by 2 (or multiply 15 by 0.5, it's the same thing) and you get 7.5.
I hope this helped! :)
