1. Sky Electric plc at present offers its customers 30 days’ credit. Half the customers, by value, pay on time. The other half takes an average of 70 days to pay. The business is considering offering a cash discount of 2 per cent to its customers for payment within 30 days. The credit controller anticipates that half of the customers who now take an average of 70 days to pay (that is, a quarter of all customers) will pay in 30 days. The other half (the final quarter) will still take an average of 70 days to pay. The scheme will also reduce bad debts by £300,000 a year. Annual sales revenue of £365 million is made evenly throughout the year. At present the business has a large overdraft (£60 million) with its bank at a cost of 12 per cent a year. Required: a) Calculate receivables outstanding under both the old and new schemes. b) How much will the scheme cost the business in discounts? c) Should the business go ahead with the scheme? d) Outline the controls and procedures that a business should adopt to manage the level of its receivables.

Problem 2: A semicircle with radius R carries a negative charge with linear density $\lambda(\theta) = \lambda_0 \cos \theta$, where $\theta$ is the angle with the x-axis. Determine the electric field vector at the center of the hemisphere. Electric field of a small element of charge dq is: $\vec{E}(\vec{r}) = \frac{dq}{4\pi\epsilon_0 r^2} \hat{r}$ and Linear charge density is: $\lambda = \frac{dq}{dl}$

This question requires you to fill in the blanks. Some steps will refer to previous answers you have typed, so it is necessary to \"submit\" after filling in each blank. The quickest way to do this is hit enter after typing instead of pushing the submit button. Please see formatting instructions below the problem. Use the double angle identity $cos(2x) = cos^2(x) - sin^2(x)$ to verify the double angle identity $cos(2x) = 2 cos^2(x) - 1$ 1. The right side is more complicated so start there: Rewrite $sin^2(x)$ using the Pythagorean identity: 2. Distribute the negative sign: 3. Group like terms: Now you have: Proven! $cos(2x) = cos^2(x) - sin^2(x)$ $= cos^2(x) - ($ $cos(2x) = $ $cos(2x) = $ $cos(2x) = $ $cos(2x) = $ $cos(2x) = $ FORMATTING INSTRUCTIONS BELOW Type in lowercase and use parentheses. For example type sin(x) not sinx. For fractions use the divide symbol \"\/\" . For example sin(x)/cos(x) for $\frac{sin(x)}{cos(x)}$ For multiplication of fractions use parentheses
