we know that initially there were 120 colonies or namely that C = 120, well, what time was that? that was the hour 0, or namely t = 0, so then
we also know that when t = 4, C = 550
For this case, the first thing we must do is define variables:
x = number of quarters
y = number of dimes
We now write the system of equations:
x + y = 28
0.25x + 0.10y = 4.05
Solving the system of equations we have:
x = 8.33
y = 19.66
Rounding:
x = 8
y = 20
Answer:
the college student has:
8 quarters
20 dimes
Just guess and tell your teacher you need help
Answer:
1/3 or 0.33
Step-by-step explanation:
Put -2 where x is in the function definition and do the arithmetic.
g(-2) = 3^(-2/2)
= 3^(-1)
g(-2) = 1/3
Of course, you know that the decimal equivalent of the fraction 1/3 is the repeating decimal 0.33333.... Rounding this to 2 decimal places gives you ...
g(-2) ≈ 0.33
