Correct Answer: B. \(\frac{140}{221}\)

Explanation

\(\cos(x+y) = \cos x\cos y - \sin x\sin y\)

Given \(\sin\) of an angle implies we have the value of the opposite and hypotenuse of the right-angled triangle. We find the adjacent side using Pythagoras' theorem.

\(Adj^{2} = Hyp^{2} - Opp^{2}\)

For triangle with angle x, \(adj = \sqrt{13^{2} - 5^{2}} = \sqrt{144} = 12\)

For triangle with angle y, \(adj = \sqrt{17^{2} - 8^{2}} = \sqrt{225} = 15\)

\(\therefore \cos x = \frac{12}{13}; \cos y = \frac{15}{17}\)

\(\cos(x+y) = (\frac{12}{13}\times\frac{15}{17}) - (\frac{5}{13}\times\frac{8}{17}) = \frac{180}{221} - \frac{40}{221}\)

= \(\frac{140}{221}\)

Correct Answer: B. \(\frac{rk^2+pm^2}{m^2}\)

Explanation

\(k = m\sqrt{\frac{t - p}{r}}\)

\(\frac{k}{m} = \sqrt{\frac{t - p}{r}}\)

\((\frac{k}{m})^2 = \frac{t - p}{r}\)

\(rk^2 = m^2 (t - p)\)

\(\therefore m^2 t = rk^2 + m^2 p\)

\(t = \frac{rk^2 + m^2 p}{m^2}\)

Correct Answer: B. falling, marginal utility is negative

Explanation

The following are the various relationships between total and marginal utility.

-When marginal utility is positive , total utility increases. - When marginal utility is zero , total utility is at maximum. - When marginal utility is negative , total utility decreases.

Correct Answer: C. Tertiary

Explanation

The correct answer is tertiary. Translation is a process performed by ribosomes to link amino acids together in a chain, and the order of the amino acids is based on a code from mRNA. The order of the amino acids in the chain is the primary structure. The secondary structure is the folding in that chain, mainly based on hydrogen bonds between parts of the chain and the surrounding water molecules. The tertiary structure is the actual three-dimensional structure of the protein. Disulfide bonds are covalent bonds between cysteine residues and are stronger than hydrogen bonds and give a stable, three-dimensional structure to what was originally just a chain of amino acids.
