A curve has equation y^3+2xy+x^2-5=0. Find dy/dx.

To find the derivative of this, we must differentiate each term with respect to x. This implies d/dx(y^3+2xy+x^2-5=0). We can differentiate each term seperately so d/dx(y^3+2xy+x^2-5=0) is equal to d/dx(y^3)...

Explain why the product of a nucleophilic addition to butanone does not effect plane polarized light.

The nucleophile will attack the d + carbon atom of the carbonyl group. Since the carbonyl group is planar, attack can occur from either side with equal probability. The product of this reaction will contain ...

Frank owns an ice cream van. When he bought the van five years ago and an ice cream cost £1.50. If the price of an ice cream increases by 3% a year how much does an ice cream cost now?

new amount = old amount * (1 + interest)^(number of times interest has occured) new amount = 1.50 * (1 + 0.03)^5 = £1.74 (rounded to 2 decimal places)
