Answer:
five and forty-four hundredths
Step-by-step explanation:
To find r, first write out the equation:

Next, multiply both sides by 2:

Now, subtract both sides by 4:

Divide both sides by 3:

The answer to this problem is
r = 2. Hope this helps and have a phenomenal day!
The solution would be x=0 because the statement is false.
Answer:
B. 9.6 %.
Step-by-step explanation:
A = P e^rt
His investment doubles so it comes to 3000 * 2 = $6000.
Substituting in the formula>
6000 = 3000e^7.2r ehere r is the interest rate.
e^7.2r = 2
Taking logs
7.2r = ln 2
r = ln2 / 7.2
r = 0.096
So the rate is 9.6%.
