Use the periodic and even–odd properties. If $f(\theta)=\sin \theta$ and $f(a)=\frac{1}{3}$ find the exact value of: (a) $f(-a)$, (b) $f(a)+f(a+2 \pi)+f(a+4 \pi)$

Why do human causes of global change occupy a larger portion of the global change model than nonhuman causes?

How is molecular biology related to genetics?

Most sample surveys call residential telephone numbers at random. They do not, however, always ask their questions of the person who picks up the phone. Instead, they ask about the adults who live in the residence and choose one at random to be in the sample. Why is this a good idea?

Compare how squids and sea slugs protect themselves in the marine biome.

For the given functions f and g, find: $g \circ f$ State the domain of each composite function. $f(x)=3 x+1 ; \quad g(x)=x^{2}$

Evaluate the expression without using a calculator. $10^{\log 45}$

The Ministry of Health in the Canadian province of Ontario wants to know whether the national health care system is achieving its goals in the province. Much information about health care comes from patient records, but that source doesn't allow us to compare people who use health services with those who don't. So the Ministry of Health conducted the Ontario Health Survey, which interviewed a random sample of 61,239 people who live in the province of Ontario. (a) What is the population for this sample survey? What is the sample? (b) The survey found that $76\%$ of males and $86\%$ of females in the sample had visited a general practitioner at least once in the past year. Do you think these estimates are close to the truth about the entire population? Why?

Which of the following is not a Python data type? a) int b) float c) rational d) string

A strain of E.coli Beu 397-recA441 is placed into a nutrient broth at $30^{\circ}$ Celsius and allowed to grow. The data shown in the table are collected. The population is measured in grams and the time in hours. Since population P depends on time t and each input corresponds to exactly one output, we can say that population is a function of time; so P(t) represents the population at time t.

$$\begin{matrix} \text{Time (hours), t} & \text{Population (grams), P}\\ \text{0} & \text{0.09}\\ \text{2.5} & \text{0.18}\\ \text{3.5} & \text{0.26}\\ \text{4.5} & \text{0.35}\\ \text{6} & \text{0.50}\\ \end{matrix}$$

Find the average rate of change of the population from 4.5 to 6 hours.
