Investment account 1 starts with a balance of $200 and doubles ever year. Investment account 2 starts with a balance of $1,000 and increases by $100 each year. How long does it take for each account to double?

Account 1 would take 1 year or 12 months to double. Account 2 would take 10 years for its ammount to double.

Step-by-step explanation:

Since Account 1 doubles each year, it would only take one year to reach the double. For Account 2, since it only increases by $100 each year, it would take 10 years to double. If 1,000 is divided by 100 we would be left with 10. By increasing the ammount by 100 for 10 years, we would be left with 1,000 after this alotted time.

Account 1 would take 1 year or 12 months to double. Account 2 would take 10 years for its amount to double.

Step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

answer: (3,11) is your answer.
