Find the sum of the measures of the interior angles of a convex 30-gon.

2 answers:

7 0

The sum of the interior angles of a polygon with N sides is (N-2) x 180 degrees.

For a 30-gon, the sum of interior angles is (28) x (180) = <u>5,040 degrees</u>.

It makes no difference whether or not the polygon is convex at every vertex.

There's an equation for that:

Sum of interior angles = 180(n - 2)
where n = number of sides

So if you have a polygon with 30 sides, the sum of the interior angles is:

180(30 - 2) = 180(28) = 5040 deg

F(x) = x^2-3<br> What is the average rate of change on the interval [-5, 2] ?

Mumz [18]

Answer:

$(-3)$ .

Step-by-step explanation:

Over this interval, the change in the value of this function is:

$f(-5) - f(2) = 22 - 1 = 21$ .

The corresponding change in the value of $x$ :

$(-5) - 2 = -7$ .

The average rate of change of function $f$ over this interval is equal to the change in the function value divided by the corresponding change in $x$ :

$\begin{aligned}& (\text{average rate of change}) \\ =\; & \frac{(\text{change in function value})}{(\text{change in $x$})} \\ =\; & \frac{f(-5) - f(2)}{(-5) - 2} \\ =\; & \frac{22 - 1}{-7} \\ =\; & \frac{21}{-7} \\ =\; & -3\end{aligned}$ .

Thus, the average rate of change of $f(x) = x^{2} - 3$ over the interval $[-5,\, 2]$ would be $(-3)$ .

explanation: the largest amount of people are the people who have 1 pet.

#4: The percent of students who have at least 3 pets is 25%.

explanation: 6 divided by 24 is 0.25 and and that converted to a percentage is 25%

#5: The median number of pets that students have is 1 pet.

explanation: the middle number of all the people in Yolanda's class is 1.

#6: The range of the number of pets is 9.

explanation: range is the largest number minus the smallest number

9 - 0 = 9

#7: #7 will be attached with this answer.

#8: There are 22 students in the class.

explanation: the added up number of students is 22.

#9: The mode value is 3 students.

explanation: the mode is the number that appears the most. 3 is the number that appears the most.

#10: The median number of concerts that students have attended is 2 concerts.

explanation: the middle number of all the numbers is 2.

#11: The concerts that the students in Mr. Ritter's class have attended in all is 72.

explanation: all the number of concerts attended added up is 72.

#12: The average (mean) number of concerts the students in Mr. Ritter's class has attended is 3 concerts.

explanation: all the concerts divided by the number of students were are is the mean.

72 / 22 is 3.27.
