To solve this problem  you must apply the proccedure shown below:
 1. You have:
 480r^(5-1)=12.288
 480r^4=12.288
 r^4=12.288/480
 r=(12.288/480)^(1/4)
 r=0.4
 2. Now, multiply r=0.4 to each term, as below:
 480x0.4=192
 192x0.4=76.8
 76.8x0.4=30.72
 30.72x0.4=12.288
 Therefore, as you can see, the answer is: 192,76.8,30.72

Use logarithms to solve the problem. Find the interest rate needed for an investment of $5800 to double in 5 years if interest i
Semmy [17]

Answer:

14.86%

Step-by-step explanation:

The principal = $5800

Time = 5 years

Amount = $ 11600

From;

A= P(1 + r)^n

Substituting values;

11600=5800(1 + r)^5

Rate= (11600/5800)^1/5 - 1

Rate= 0.1486

Therefore

Rate= 14.86%

6m^5 + 3 + m^3 - 4m)- (m^5 +2m^3 - 4m +6) =
devlian [24]

Answer:

5m^5-m^3-3

Step-by-step explanation:

What you do is you have to distribute the negative sign into the equation.

-m^5-2m^3+4m-6. Next, you will either add or subtract from the other equation.

6m^5-m^5=5m^5.

m^3-2m^3=-m^3.

-4m+4m=0m or you don't put anything.

3-6=-3. Then you put it all together to get.

5m^5-m^3-3 as your answer.
