Answer:
9572 visitors
Step-by-step explanation:
This is exponential: y=ab
a = initial value
b = growth rate
It will grow by 5% each year but also keep the same amount as last year (100% of last year's visitors)
a = 7500
b = 1.05
Plug in x=5
9572.111719 = 9572 visitors
Answer:
27°,63°
Step-by-step explanation:
Let the two angles be a and b.
They are complementary, meaning they add up to 90. Thus:
And we are told their difference is 36. Therefore:
Solve for the system of equations. Add b to both sides in the second equation:
Substitute this into the first:
Combine like terms;
Subtract 36:
Divide by 2:
So, b is 27 degrees.
Use the second equation again:
Now that we know b is 27, substitute:
Add 27 to both sides:
So, a is 63 degrees.
And we're done :)
