Answer:

Years = natural log (total / principal) / rate

Years = natural log (2,500 / 1,450) / .06

Years = natural log (1.724137931) / .06

Years = 0.54472717542 / .06

Years = 9.078786257

Years = 9.1 (rounded)

Answer:

20.7 years

Step-by-step explanation:

Use the "compound amount, compounding continuously" formula:

A = Pe^(r · t)  

Here,

A = $2,500 = $1,450e^(0.06 · t)

Divide both sides by $1,450:  1.724 = e^(0.06 · t)

Taking the natural log of both sides, we obtain:

ln 1.724 = (0.06 · t).

Finally, we divide both sides by 0.06, obtaining:

ln 1.724

------------ = t = 20.7

   0.06

The Investment will reach a value of $2.500 in approximately 20.7 years.

Write an equation in standard form of the line that passes through (3, 1) and has a y intercept of -2
aleksandr82 [10.1K]

Step-by-step explanation:

First of all, use substitution to find slope

(1) = m(3) - 2

3 = m3

m = 1

With both the slope and y int, you can write it in y int form

y = 1x - 2

Convert that to standard form

-x + y = -2

Applying GCF and LCM to fraction Operations?<br>.<br>. PLZ HELP
I am Lyosha [343]
When multiplying fractions just multiply the numerator and denominators together, then simplify the fraction you get.

To solve the addition problem, first convert 2 and 1/2 to an improper fraction. It should be 5/2. Now 3/8 and 5/2 must be added together.

To add these, they must have the same denominator. Let's give 5/2 a denominator of 8, so it matches 3/8.

To give 5/2 a denominator of 8, you are starting with a denominator of 2. 2 × 4 = 8, so you must multiply 5/2 by 4.

You should get 20/8. Now you have to add 20/8 and 3/8. The only thing you add is the numerator, so you should get 23/8 as a final answer.

For the subtraction problem, do these same steps to make the fractions you must subtract have the same denominator, then subtract only the numerator to get the answer. Once you solve the subtraction problem, text me what you got so I can check it for you. :)
