After you type in your equations and hit graph you notice that, if you are in the standard window, your parabola is cut off so you have to choose your "window" button to change the viewing window to see the whole graph. Then you would use your 2nd button and "trace" and "intersect" to find the points of intersection of the 2 graphs. The first point is at (-.90901, 16.81812) and the second point is at (5.9090909, 3.1818182). Graphing calculators are quite amazing!

Bippity boppity pls help me find this functions property
Semmy [17]

Answer:

Period ⇒ 40

Amplitude ⇒ 12

Mid-line ⇒ 32

Step-by-step explanation:

The table is counting by 4's and the period is the amount of space between 2 peaks. In this scenario, we can find the peaks by looking for two of the same highest value (44). We can see that x=40 has a value of 44 while the other is actually not shown because it would be located at x=0. Therefore the period is 40

<u />

The amplitude can be found by using the following:

\frac{1}{2}|max - min|

Our maximum is 44 and our minimum is 20.

\frac{1}{2}|44 - 20|

\frac{1}{2}|24|

\frac{1}{2}(24)

The amplitude is 12

The amplitude is the distance from the peak to the mid-line. To find the mid-line, we can either subtract our amplitude from our maximum value (44) or add our amplitude to our minimum value (20)

44 - 12 = 32

20 + 12 = 32

Therefore our mid-line is y = 32

~Hope this helps!~

What are the solutions to the inequality (x-3)(x+5) greater than or equal to 0?
amid [387]

Answer:

C

Step-by-step explanation:

If this was an equation...

(x-3)(x+5) = 0

x = 3, -5

So 3 and -5 are the minimum and the maximums.

So we convert that into an inequality.

-5 <= x <= 3

Angles C and D are supplementary, if angle C equals 126, what is angle D
Elis [28]

Answer:

angle D = 54°

Step-by-step explanation:

Supplementary angles sum to 180°

To calculate D, subtract angle C from 180

angle D = 180° - 126° = 54°
