Nadia is a stockbroker. She earns 11% commission each week. Last week, she sold $7,000 worth of stocks. How much did she make

makvit [3.9K]

Answer:

Nadia's commission per week is $770

Amount Nadia made in commission in 2011 is $40,040

Step-by-step explanation:

Commission made last week = 11% of $7,000

Therefore commission made last week = 0.11 × $7,000 = $770

Whereby Nadia averages the same aount each week, the amount Nadia would make in commission in 2011 is given by

Amount Nadia makes per week in commission = $7,000

Number of weeks in a year = 52 weeks. Therefore, amount Nadia makes in one year is given by

Amount in commission per week × 52 weeks

=$770 × 52 = $40,040

Amount Nadia made in 2011 = $40,040.

The indicated function y1(x) is a solution of the given differential equation. Use reduction of order or formula (5) in Section

lisabon 2012 [21]

Answer:

$\therefore y_2(x)=-\frac{e^{-6x}}{8}$

The general solution is

$y=c_1e^{2x}-c_2.\frac{e^{-6x}}{8}$

Step-by-step explanation:

Given differential equation is

y''-4y'+4y=0

and $y_1(x)=e^{2x}$

To find the $y_2(x)$ we are applying the following formula,

$y_2(x)=y_1(x)\int \frac{e^{-\int P(x) dx}}{y_1^2(x)} \ dx$

The general form of equation is

y''+P(x)y'+Q(x)y=0

Comparing the general form of the differential equation to the given differential equation,

So, P(x)= - 4

$\therefore y_2(x)=e^{2x}\int \frac{e^{-\int 4dx}}{(e^{2x})^2}dx$

$=e^{2x}\int \frac{e^{-4x}}{e^{4x}}dx$

$=e^{2x}\int e^{-4x-4x} \ dx$

$=e^{2x}\int e^{-8x} \ dx$

$=e^{2x}. \frac{e^{-8x}}{-8}$

$=-\frac{e^{-6x}}{8}$

$\therefore y_2(x)=-\frac{e^{-6x}}{8}$

The general solution is

$y=c_1e^{2x}-c_2.\frac{e^{-6x}}{8}$

kim drives 156 miles from rotherham to london. she drives at an average speed of 60 miles per hour. she leaves rotherham at 7:30

Elza [17]

Okay. So 7:30-10:00 is 2 hours 30 minutes or 2 1/2 hours. To find this, we have to do 156/60 to find the amount of time it takes to get there. 156/60 is 2.6, so it would take more than 2 1/2 hours to arrive in London. Kim does not arrive in London before 10:00 AM.
