Does the graph f(x)=-2x^2 -1 have a maximum or a minimum? Explain.
Serga [27]

Answer:

It has a maximum

Step-by-step explanation:

The way I think about it is looking at "a" (the leading variable's coefficient, so __x²), if it's negative, the graph is a frown, but if it's positive, it's a smile. In this case, a is -2, so the graph would have the shape of a frown, which has a maximum.

I hope this helped!

First you would add the two angles together to get 105. The. you do 180-105 to get 75. That is the missing angle. From there you would correspond the angles with the sides. Therefore the answer is Angle AB, angle BC, angle CA. these are in order from shortest to longest

Question 1
Vitek1552 [10]

Answer:

M.A.D= 4.9

Step-by-step explanation:

Given

12.7, 22, 23.5, 24, 11, 22

Required

Determine the M.A.D

Start by calculating the Mean

Mean = \frac{\sum x}{n}

In this case, n = 6

So:

Mean = \frac{12.7 + 22 + 23.5 + 24 + 11 + 22}{6}

Mean = \frac{115.2}{6}

Mean = 19.2

Subtract the mean from each element

12.7 - 19.2 = -6.5

22 - 19.2 = 2.8

23.5 - 19.2 = 4.3

24 - 19.2 = 4.8

11 - 19.2 = -8.2

22 - 19.2 = 2.8

Take absolute value of the results above

|-6.5| = 6.5

|2.8| = 2.8

|4.3| = 4.3

|4.8| = 4.8

|-8.2| = 8.2

|2.8| = 2.8

The mean of the above gives the MAD

M.A.D= \frac{\sum |x - u|}{n}

M.A.D= \frac{6.5 + 2.8 + 4.3 + 4.8 + 8.2 + 2.8}{6}

M.A.D= \frac{29.4}{6}

M.A.D= 4.9
