6a² + 3 = 435
First subtract 3 from both sides:
6a^2 = 432
Divide both sides by 6:
a^2 = 432/6
a^2 = 72
Now take the square root of both sides to get a:
a = √72
Answer:
roughly 15 years
Step-by-step explanation:
The formula for continuous compounding is
A = Pe^(rt), where P is the initial amount (principal), r is the interest rate as a decimal fraction, and t is the number of years. Here:
$6900 = $3600*e^(0.043*t). Let's solve this for t. To accomplish that,
take the natural log of both sides:
ln 6900 = ln 3600 + 0.043t. Subtracting ln 3600 from both sides, we get:
8.839 = 8.189 + 0.043t, or 0.6506 = 0.043t. Dividing both sides by 0.043 yields
0.6506
t = --------------- = 15.13 years, or about 15 years 2 months, or roughly 15 years
0.043
Answer:
$2.50
Step-by-step explanation:
11 9/10 + 5 6/10 = 16 15/10 or 16 + 1.50 = 17.50
20 - 17.50 = 2.50
