Answer:
$24,498,509.74
Step-by-step explanation:
The formula for the value as a function of time is ...
V(t) = P·e^(rt)
Filling in the numbers and doing the arithmetic, we have ...
V(35) = 3,000,000·e^(0.06·35) ≈ 24,498,509.74
Compounded continuously for 35 years, the investment will be worth $24,498,509.74.
Answer:
It is a solution of the ordered pair.
Step-by-step explanation:
The y intercept is (0,-2)
Answer: There were 78 red apples at the party.
Step-by-step explanation:
This situation can be represented by the equation
x + 3x + 2(3x) = 130 where x is the number of green apples, 3x is the number of yellow apples and 2(3x) is the number of red apples.
Now solve for x
x +3x +2(3x) =130
4x + 6x = 130
10x = 130
x = 13
Now we know that x is 13 so put it into the expression for red apples and solve for the actual number of red apples.
2 * (3*13) = ?
2 * 39 = 78
