Answer:
Step-by-step explanation:
The first thing you ought to do is find out what you are trying to get. Desmos is an ideal program to do that if you don't have a graphing calculator. Just search for Desmos. It is pretty obvious once you get there. I've enclosed the graph to show you what it looks like.
Notice what happens around 5. The graph splits because effectively, you are dividing by 0 when you put 5 into the denominator. The question arises why doesn't the same thing happen at 0. It should: There is a discontinuity but it is very tiny. So the domain numbers that you should graph are
-1 0™ 1 2 3 4 4.5 4.8 5.3 5.4 6 7
™I wouldn't make 0 a part of this domain. But you can indicate with a dot where the graph goes.
I haven't filled in the range numbers. That's your job. All you have to do is fill in the table with points. Or you can put them on the graph that I have enclosed just to see where they points belong.
A graph is not to convey accuracy. It is to show the shape of function in question.

Answers
Answer:[tex]-\frac{189}{208}[/tex]
Step-by-step explanation:
Given
[tex]\sin x=\frac{8}{10}[/tex]
x lies in the second quadrant where sin and cosec is positive and rest trigonometric functions are negative
so, [tex]\cos x=-\sqrt{1-sin ^2 x}\\\cos x=-\sqrt{1-(\frac{8}{10})^2}=-\sqrt{\frac{36}{100}}\\\cos x=-\sqrt{\frac{6}{10}}[/tex]
[tex]\tan x=\frac{\sin x}{\cos x}=-\frac{4}{3}[/tex]
similarly, [tex]\tan y=-\frac{12}{5}[/tex]
Also, y lies in 4 th Quadrant where cos and sec is positive and rest trigonometric functions are negative
[tex]\sec y=\sqrt{1+\tan ^2y}=\sqrt{1+(-\frac{12}{5})^2}\\\sec y=\frac{13}{5}\\\cos y=\frac{5}{13}\\\sin y =\frac{\tan y}{\cos y}=-\frac{12}{13}[/tex]
Now putting the values
=[tex]\dfrac{\cos x \cos y+\sin x\sin y}{\tan x-\tan y}=\dfrac{(\frac{-6}{10})(\frac{5}{13})+(\frac{8}{10})(\frac{-12}{13})}{(\frac{-8}{6})-(\frac{-12}{5})}\\\dfrac{\cos x \cos y+\sin x\sin y}{\tan x-\tan y}=\dfrac{\frac{-126}{130}}{\frac{16}{15}}=-\frac{189}{208}[/tex]
The points (10,16) and (30,48) form a proportional relationship. Find the slope of the line through the points. Then use the slope to graph the line.
Answers
Answer:
1.6
Step-by-step explanation:
Step one:
given data
x1=10
y1=16
x2=30
y2=48
Required
The slope of the given points
Step two:
The expression for the slope is
S= change in y/change in x
S= y2-y1/x2-x1
S= 48-16/30-10
S=32/20
S=1.6
Hence the slope is 1.6

Is the binomial a factor of the polynomial function?
f(x) = x^3 + 3x^2 – 25x – 75
Select Yes or No for each binomial.
Answers
Answer:
Yes, the binomial is a factor of the polynomial function.
Step-by-step explanation:
Consider the given polynomial.
Factor out the common term [tex]x^2[/tex] from the first two terms and [tex]-25[/tex] from the last two terms.
[tex]x^3 + 3x^2 -25x-75=x^2(x+3)-25(x+3)[/tex]
Factor out the polynomial.
[tex]x^2(x+3)-25(x+3)=(x+3)(x^2-25)[/tex]
Further, simplify.
[tex](x+3)(x^2-25)=(x+3)(x+5)(x-5)[/tex]
Therefore, [tex]x^3 + 3x^2 -25x-75=(x+3)(x+5)(x-5)[/tex]
A binomial factor is simply a factor with two terms, like (x - a).
Hence, the given polynomial function is binomial as it contains the factor with two terms, like (x - a).
Answer:
Yes No
Yes(x+3) No (x−1)
Yes – (x−5)
Yes – (x+5) No – (x−3)

It takes Maria 10 hours to pick forty bushels of apples. Kayla can pick the same
amount in 12 hours. How long will it take if they work together? Round your answer
to the nearest tenths place.
Answers
Answer:
5.3
Step-by-step explanation:
It will take a time 0f 5.5 hours to pick 40 bushels of apple if they worked together.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Suppose we have two ratio p : q and r : s.
If both these ratios are proportional, then we can write it as p: q : : r : s.
This is same as p : q = r : s or p/q = r/s
Given that,
Amount of bushels picked by Maria in 10 hours = 40
Amount of bushels picked by Maria in 1 hour = 40/10 = 4
Amount of bushels picked by Kayla in 12 hours = 40
Amount of bushels picked by Maria in 1 hour = 40/12 = 3.333
Amount of apple picked by both Maria and Kayla in 1 hour if they worked together = 4 + 3.333 = 7.333
Let x be the time taken to pick 40 bushels of apple by both.
Using proportional concept,
x / 40 = 1 / 7.333
x = 40 / 7.333
x = 5.4548 ≈ 5.5 hours
Time taken if they both worked together is 5.5 hours.

Write the final equation using the slope-intercept form perpendicular to 3y = x − 4 and passes through the point (−2, 1)
Answers
Answer:
y=-3x-5
Step-by-step explanation:
given equation:
3y=x-4
slope intercept form is y=mx+b
(m is the slope, b is the y intercept)
divide by 3
y=1/3x-4/3
perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.
so to find the slope of the perpendicular line, use this equation:
1/3m=-1
multiply by 3
m=-3
the slope of the new line is -3.
here is our equation so far:
y=-3x+b
now, we need to find b.
Since the equation of the line passes through the point (-2,1) we can substitute that into the equation to find b
1=-3(-2)+b
multiply
1=6+b
subtract 6
-5=b
so the line is y=-3x-5
