What does the saying "the dose makes the poison" mean? What matters is the amount of a toxic substance present; whether or not we are exposed to the toxin is not relevant. Any amount of a dangerous substance is unacceptable and counting the numbers of compounds detected is a reliable way to establish danger. Most substances are toxic at some level of exposure depending on the substance and the nature of the exposure. All substances have equivalent potential for harm, so exposure to any of them is risky.

For a process such as this to be "in statistical control," only random patterns of points should appear on the control chart. The process is "not in statistical control" when any non-random patterns appear on the chart. Three commonly used tests or rules for signaling that a process may not be in statistical control are: - Rule 1: One or more points fall outside one of the chart's control limits - Rule 2: Nine points in a row are on the same side of the chart's centerline - Rule 3: Six points in a row are increasing (or decreasing). Using these three rules, identify which (if any) of the rules gives an "out of control" signal, and indicate the subgroup number at which the signal is first given.

Which statement best describes how argument outlines are unique (different from outlines written for other types of essays)? Argument outlines require more careful thought because the writer must apply persuasive strategies when choosing the arrangement of ideas and the contents of all paragraphs, including the introduction, all body paragraphs, and the conclusion. Argument outlines require teamwork: you must find a friend who disagrees with you and ask that person to write all of the opposing parts of your outline. Because argument essays never include conclusion paragraphs, you should not outline ideas for a conclusion paragraph. Argument outlines will outline just the research and how it will be used, which means they are much shorter than outlines for other types of essays.

Analyze the polynomial function f(x)=(x+5)^2(x-6)^2 using parts (a) through (h) below. (b) Find the x-and y-intercepts of the graph of the function. The x-intercept(s) is/are -5,6. The y-intercept(s) is/are 900. (c) Determine the real zeros of the function and their multiplicity. Use this information to determine whether the graph crosses or touches the x-axis at each x-intercept. The real zero(s) of f is/are -5,6. The lesser zero is a zero of multiplicity 2, so the graph of f touches the x-axis at x=-5. The greater zero is a zero of multiplicity 2, so the graph of f touches the x-axis at x=6.

You can use these measurement to express the velocity of the puck using component form. For example, if you measured the horizontal velocity as 25 cm/s and the vertical velocity as 50 cm/s, you could write the velocity of the puck like this: v x=25 cm/s v y=50 cm/s You can also express the velocity of the puck in angle-magnitude form. This means you state the magnitude, or amount of the quantity, as well as the direction expressed as an angle. In this case, the magnitude is the velocity in meters per second, and the direction is the angle θ in the image above. Here's how. - to find the magnitude, or amount, of the velocity, you can see from the drawing that the length of the velocity arrow is the hypotenuse of the triangle - Use the Pythagorean theorem to calculate the length of the hypotenuse: v=√(v x+v y^2) Make these calculations using the horizontal and vertical velocities you measured, and enter the value of the velocity here. cm/s
