How does exercise help you lose weight?

You have heard that it is dangerous to stand under trees in electrical storms. Why?

In this exercise, simplify the given expression.

$$\log _6 1$$

In this exercise, sketch the graph of the equation.

$$-x^2-8 y=0$$

Interpret the Y-value shown at the bottom of the screen in the earlier exercise.

Determine a basis for the kernel of

(b) the linear transformation in Exercise $18.$

Predict the effect (if any) of an increase in temperature on the electrical conductivity of
(a) antimony, $\mathrm{Sb}$;

In this exercise, verify each identity.

$$\cos x \csc x=\cot x$$

Distinguish between electric power and electrical energy. Include units in your answer.

Does the graph in the earlier exercise represent $x$ as a function of $y$? Explain.

What does the program segment in Exercise 27 do?

Determine an equation for the graph you drew in the Exercise earlier.

In this exercise, graph the given function $y=f(x)$ by hand.

$$f(x)=(x-3)^3$$

In Exercise find $f ^ { \prime } ( x )$.

$$f ( x ) = x - 4 \csc x + 2 \cot x$$
