Hi there!

\large\boxed{\text{Average rate} = 2}

Use the following equation to solve:

\text{Average rate} = \frac{f(x_{2}) - f(x_{1})}{x_{2} - x_{1}}

Solve for the y-values of the equation at the given x values:

f(1) = 1² - 4(1) + 10 = 7

f(5) = 5² - 4(5) + 10 = 15

Plug  the solved values into the equation:

\text{Average rate} = \frac{15 - 7}{5-1}

Simplify:

\text{Average rate} = \frac{8}{4} = 2

Is the following statement a good definition? Why? An obtuse angle is an angle whose measure is greater than 90°.
Virty [35]

180° measures more than 90°, so according to the given statement, a plane angle is also an obtuse angle, and that is incorrect. From that, we conclude that the statement is not a good definition.

<h3>Is the following statement a good definition? </h3>

The given statement is:

"An obtuse angle is an angle whose measure is greater than 90°."

This is the common, but incorrect, definition for obtuse angles.

We know that an angle that measures 180° is called a plane angle and by definition, a plane angle is not an obtuse angle.

And the angles larger than 180° (and smaller than 360°) are the reflex angles.

Now, 180° measures more than 90°, so according to the given statement, a plane angle is also an obtuse angle, and that is incorrect. From that, we conclude that the statement is not a good definition.
