The polynomial p(x) is, p(x)= x3-5x2-8x+48.Use the Factor Theorem to show that (x + 3)is a factor of p(X)

First of all it is using the factor theorem. 

so need to use that to show it is a factor 

We do this by P of (-3) should = 0 

So substitute x with -3 

 p(-3)= (-3)3 - 5 (-3)2- ...

Find the area R under the curve when f(x)=xcos(x) between the limits x=0 and x=2

After careful consideration, we can see the function f(x) is the product of two individual functions. Usually, to find the area under a curve we integrate its function between a set limit. Given our situa...

A chemist mixes together 0.450 mol N2 with 0.450 mol H2 in a sealed container. The mixture is heated and allowed to reach equilibrium. At equilibrium, the mixture contains 0.400 mol N2 and the total pressure is 500 kPa. Calculate Kp.

balanced equation:  N2 (g) + 3H2 (g) <---> 2NH3 (g)  Both reactants and products are gases, therefore it affect Kp value. This equation reaches equi...

Using mendelian genetics, explain how two brown eyed parents can have a blue eyed child. Which of the alleles is dominant? You may use a graph to support your explanation (Tip: Assume a simple dominance and inheritance )

Given that the brown eyed parents are able to produce blue eyed offspring, it is safe to assume that they are both heterozygots for eye colour and that the brown allele is dominant (A) over the blue allel...
