Answer:
The answer to your question is:
Step-by-step explanation:
Data
f(x) = -2x² + 8x - 2
Process
-2x² + 8x = y + 2
-2(x² - 4x + 4) = y + 2 - 8
-2(x - 2)² = y - 6
(x - 2)² = 1/2 (y - 6)
Vertex = (2, 6)
Axis of symmetry = x = 2
y-intercept
f(0) = -2(0)² + 8(0) - 2
f(0) = 0 + 0 - 2
f(0) = -2
Domain (-∞, ∞)
Range (-∞, 6]

Answer:
6.93 years.
Step-by-step explanation:
We have been given that $3550 is invested at 10.0% compounded continuously.
To solve our given problem, we will use continuous compounding formula.
, where,
A = Final amount,
P = Principal amount,
e = Mathematical constant,
r = Interest rate in decimal form,
t = Time
Substitute the given values:
Take natural log of both sides:
Using property , we will get:
Switch sides:
Therefore, it will take approximately 6.93 years for the balance to reach $7100.
