The least common denominator is one, since all of these numbers are actually whole numbers. They're actually all $\frac{x-3}{1} \frac{x+3}{1} \frac{x^2-9}{1}$
If you mean the greatest common factor, then it's obviously $x$

Calvin evaluated -2/3 *5 1/6 using the steps below.

matrenka [14]

For this case we have to evaluate the following expression,

$- \frac {2} {3} * 5 \frac {1} {6}$

We must follow the steps below:

We convert the mixed number into a fraction:

$- \frac {2} {3} * \frac {6 * 5 + 1} {6} =\\- \frac {2} {3} * \frac {31} {6} =$

We multiply the fractions, taking into account that:

$- * + = -\\- \frac {2 * 31} {3 * 6} =\\- \frac {62} {18} =$

We simplify:

$- \frac {31} {9}$

We convert to mixed number:

$-3 \frac {4} {9}$

Answer:

$-3 \frac {4} {9}$

What is the annual compound interest rate for an investment account modeled by the function y=12⋅1.18t ?

NikAS [45]

Answer:

The interest rate for the given investment is 18%.

Step-by-step explanation:

We are given that,

The function representing the investment model is, $y=12(1.18)^t$ .

It is required to find the interest rate for the investment.

Since, the function can be re-written as,

$y=12(1.18)^t$

i.e. $y=12(1+0.18)^t$

So, on comparing with the formula for compound interest i.e. $A=P(1+r)^t$ , where 'r' is the interest rate.

We have that,

The interest rate for the given investment is 0.18 i.e. 18%.
