Graphing Rational Functions<br> HELP ME URGENT

Can someone pls help me

Ivan

Answer:

arc EFC = 237°

Step-by-step explanation:

arc DEF = 140°

arc EF = 140° - 83° = 57°

arc DC = arc FG

arc DC = (360° - 140° - 140°)/2 = 40°

arc EFC = arc CG + arc FG = arc EF = 140° + 40° + 57° = 237°

Need help lol

We need to read the graph to see which are the two quantities related and how these are related.

The two quantities on the graph are:

Distance from Elena's house
Time.

Such that the <u>distance from Elena's house is a function of the time.</u>

<h3>How to read the graph?</h3>

We need to only read graph A, notice that she is coming back from school and going home, the graph starts at a high value and ends at zero. So we can assume that the vertical <u>zero represents her home.</u>

We know two events, first, she goes home and needs to come back to search for something, this is represented with the first "inverted peak" of graph A, then we have a constant line, that represents the time she is in the school looking something in her locker.

Then she goes home again, this time she finds a friend and goes to the library (this is why the line goes up again) and then she stops at the library for some time (this is why the line is horizontal for some time). Finally, she goes home, represented by the last segment of the line that intercepts the horizontal axis.

Then the two things represented in the graph are:

Distance from Elena's house (in the vertical axis) and time (in the horizontal axis).

This means that the <u>distance from Elena's house is a function of time.</u>

(The quantity in the vertical axis is a function of the quantity in the horizontal axis).

How does your cosine graph change when including the d-value?

fredd [130]

Answer:

Changing value of "d" changes the vertical shift of the cosine graph.

Step-by-step explanation:

Question says to find about how does your cosine graph change when including the d-value.

General equation of cosine function can be given as:

$y=a\cdot\cos\left(bx-c)\right)+d$

In that formula, value of "d" gives vertical shift.

So changing value of "d" changes the vertical shift of the cosine graph.

PLEASE HELP ITS MATH

xxMikexx [17]

Answer:

y=[-4]x+[10]

Step-by-step explanation:

For a line to be perpendicular to another it must have the reverse reciprocal of the opposite line, to find the reverse reciprocal you take your slope, flip the numerator and denominator, and multiply it by -1.

The slope $\frac{1}{4}$ turns into $\frac{4}{1}$ and is then multiplied by -1 to become $\frac{-4}{1}$ which can be simplified down to: $-4$
