Answer:

The answer is 9 1/5.

Step-by-step explanation:

Step-1: Convert the mixed fractions into improper fractions.

=> -2 2/5 ⇒ -12/5
=> -3 5/6 ⇒ -23/6

Step-2: Multiply the improper fractions.

=> -12/5 x -23/6
=> 12/5 x 23/6

[The minuses on both fractions cancelled out because when there are 2 minuses multiplying each other, the minuses cancel out.]

=> 2/5 x 23/1
=> 46/5

Step-3: Convert the improper fraction into mixed fraction.

=> 46/5 = 9 1/5

Hence, the answer is 9 1/5.

Hoped this helped.

5x^2+11x=0 quadratic equation

hammer [34]

$5x^{2} + 11x = 0
$
$5x^{2} + 11x + 0 = 0$
$x = \frac{-(11) +/- \sqrt{(11)^{2} - 4(5)(0)}}{2(5)}$

$x = \frac{-11 +/- \sqrt{121 - 0}}{10}$

$x = \frac{-11 +/- \sqrt{121}}{10}$

$x = \frac{-11 +/- 11}{10}$

$x = \frac{11 + 11}{10}$    $x = \frac{11 - 11}{10}$

$x = \frac{22}{10}$          $x = \frac{0}{10}$

$x = 2.2$       $x = 0$

Anna’s bank gives her a loan with a stated interest rate of 10.22%. How much greater will Anna’s effective interest rate be if t

Mumz [18]

Answer:

d. 0.0463% points.

Step-by-step explanation:

We have been given that Anna's bank gives her a loan with a stated interest rate of 10.22%.

To find the how mush the interest rate is effective, while compounded daily than compounded monthly, we will find the difference between interest compounded daily from interest compounded monthly.

$\text{The effectiveness of interest rate compounded daily}=(1+\frac{r}{365})^{365}-(1+\frac{r}{12})^{12}$

Let us convert our given rate in decimal form.

$10.22\%=\frac{10.22}{100}=0.1022$

Upon substituting our given interest rate in above equation we will get,

$\text{The effectiveness of interest rate compounded daily}=(1+\frac{0.1022}{365})^{365}-(1+\frac{0.1022}{12})^{12}$

$\text{The effectiveness of interest rate compounded daily}=(1+0.00028)^{365}-(1+0.008516666)^{12}$

$\text{The effectiveness of interest rate compounded daily}=(1.00028)^{365}-(1.008516666)^{12}$

$\text{The effectiveness of interest rate compounded daily}=1.1075891260304368-1.1071257622419648$

$\text{The effectiveness of interest rate compounded daily}=0.000463363788$

Let us convert our rate in percentage by multiplying our answer by 100.

$\text{The effectiveness of interest rate compounded daily}=0.000463363788*100$

$\text{The effectiveness of interest rate compounded daily}=0.0463363788\%$

Therefore, the Anna's effective interest rate will be 0.04633% points and option d is the correct choice.
