Answer:
4.5, -27, 162,-972, 5832
Step-by-step explanation:
The given recursive definition is,
This will form a geometric sequence with first term 4.5 and common ratio r=-6.
When n=2, we have:
When n=3, we get:
When n=4, we get:
When n=5, we get:
Therefore the first five terms are:
4.5, -27, 162,-972, 5832
Substract by 12 from 42, and keep going down until you hit -54, which is 8 hours!
Answer:
The second step because she distributed within the parentheses without adding the negative sign to 13
Answer:
(-3,5)
Step-by-step explanation:
4x + 3y = 3
x − 3y = −18
Solve by addition/Elimination
x = -3
y = 5
So,
The solution of the system is (-3,5).

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%.
