Answers
For the given function,
Vertical Asymptote:- x =-3
Horizontal asymptote:- y =20
Oblique asymptote :- No oblique asymptote
Asymptote:
A vertical asymptote is found by letting the denominator equal zero. A horizontal asymptote is found by comparing the leading term in the numerator to the leading term in the denominator. The degree of the numerator is greater than the degree of the denominator, so there is no horizontal asymptote.
Oblique asymptotes occur when the degree of the denominator of a rational function is one less than the degree of the numerator
given,
R(x) = [tex]\frac{20x}{x+3}[/tex]
Vertical Asymptote:-
Equate denominator to zero
x +3 = 0
x = -3
Horizontal asymptote:-
Here degree on x in numerator and denominator is same,
so horizontal asymptote will be,
y= 20/1
y = 20
Oblique asymptote:-
There won't be any slant asymptote, because degree in numerator is equal to the degree in denominator.

Find the unknown angle measure. 33 mZFGH: mZGFH: mzGHF: 33° х F 28 H
Answers
m∠FGH =33º, m∠GFH =119º and m∠GHF= 28º
1) Since the sum of all interior angles of any triangle is always equal to 180º, we can write:
m∠f + m∠H + m∠G = 180º Plug it into that the following measures
x +33º +28º= 180º
x + 61º = 180º
x = 180 -66
x =119º

First, we will use the Pythagorean theorem to compute the hypotenuse:
[tex]\begin{gathered} h^2=(6.5m)^2+(2.6m)^2 \\ =42.25m^2+6.76m^2 \\ =49.01m^2. \end{gathered}[/tex]Then:

Use the correct trigonometric function to solve for both x and y .
Answers
As per given by the question.
There are given that a triangle.
Now,
Suppose given triangle is ABC.
Then, redraw the given triangle.
Now,
For finding the value of x, and y;
First find the value of x with the help of sine trigonometric function.
So,
[tex]\sin 35^{\circ}=\frac{AB}{AC}[/tex]Then,
Substitute the value x for AB and 22 for AC.
SO,
[tex]\begin{gathered} \sin 35^{\circ}=\frac{AB}{AC} \\ \sin 35^{\circ}=\frac{x}{22} \\ 0.57=\frac{x}{22} \\ x=0.57\times22 \\ x=12.54 \end{gathered}[/tex]Now,
For finding the value of y,
Here, use pythagoras theorem in triangle ABC.
So, from the pythagoras theorem;
[tex]AB^2+BC^2=AC^2[/tex]Then,
Substitute the value in above formula;
So,
[tex]\begin{gathered} AB^2+BC^2=AC^2 \\ x^2+y^2=(22)^2 \end{gathered}[/tex]Now, put the value 12.54 for x,
So,
[tex]\begin{gathered} x^2+y^2=(22)^2 \\ (12.54)^2+y^2=(22)^2 \\ 157.25+y^2=484 \\ y^2=484-157.25 \\ y^2=326.75 \end{gathered}[/tex]Then,
[tex]\begin{gathered} y^2=326.75 \\ y=\sqrt[]{326.75} \\ y=18.076 \end{gathered}[/tex]Hence, the value of x is 12.54 and the value of y is 18.076.

The mean of the probability distribution is called expected value and it is given as
E(X) = Σxᵢpᵢ
where
xᵢ = each variable = Number of times Danny eats out
pᵢ = probability of each variable
n = number of variables
p = probability of one variable

A video production company is planning to produce instructional videotape. The producer estimates that it will cost $84,000 to shoot the video and $15 per unit to copy and distribute the tape. The wholesale price of the tape is $50 per unit. How many units must be manufactured and sold each month for the company to break even?
Answers
Second question
In order to break even,
total revenue must be equal to total cost. In this case, there is no profit
Let x represent the number of units of tape that would be manufactured to break even.
From the information given,
cost of shooting the video = 84000
If the cost of producing a unit is $15, it means that the cost of x units would be 15x
The total cost of producing x units is
15x + 84000
The wholesale price of the tape is $50 per unit. It means that the revenue from selling x units would be 50x
To break even, it means that
15x + 84000 = 50x
50x - 15x = 84000
35x - 84000
x = 84000/35
x = 2400
2400 units must be manufactured and sold each month for the company to break even

Nick used a rope to make a rectangle and a circle below. If 10 cm rope was left, what was the original length of the rope? cm 10 cm 7 cm
Answers
To find the original length of the rope, we must find the length of rope used in the rectangle and in the circle, and add it to the length of rope that was leftover.
The length of rope used in the rectangle would be the perimeter of the rectangle, the perimeter of the rectangle is the sum of all his sides.
Perimeter of a rectangle = side + side + side + side
[tex]\text{Perimeter rectangle= 10+7+10+7=34 cm}[/tex]The question gives us the perimeter of the circle, 20 cm this measure was the length of rope used in the circle.
[tex]\text{Perimeter circle= 20 cm}[/tex]Now the total length of the rope was: The sum of the perimeters of both rectangle and circle and the length of rope that was left.
Total length rope = 34 + 20 + 10 = 64 cm

Jaden and Lola are hosting events that are catered by the same company. Jaden plans to have 82 adults and 96 children attend, so the total projected cost of his meals is $5,664. Lola has 65 adults and 49 children on his guest list, so she will pay the caterer $4,002. How much does the caterer charge for each meal?
Answers
Let's use the variable x to represent the cost of one adult meal, and y to represent the cost of one child meal.
If the cost of 82 adult meals and 96 children meals is $5,664, we can write the following equation:
[tex]82x+96y=5664[/tex]If the cost of 65 adult meals and 49 children meals is $4,002, we can write the equation:
[tex]65x+49y=4002[/tex]To solve this system, let's solve the second equation for y and then use its value in the first equation:
[tex]\begin{gathered} 65x+49y=4002 \\ 49y=4002-65x \\ y=\frac{4002-65x}{49} \\ \\ 82x+96y=5664 \\ 82x+96(\frac{4002-65x}{49})=5664 \\ 82x+7840.653-127.347x=5664 \\ -45.347x=-2176.653 \\ x=48 \\ \\ y=\frac{4002-65\cdot48}{49} \\ y=18 \end{gathered}[/tex]Therefore every adult meal costs $48 and every child's meal costs $18.

Assuming this pattern continues, how much, in British Pounds, will Janelle's piece of art be valued at after 10 years? Round your answer to the hundredths place.
Answers
Step-by-step explanation:
The art piece originally costs £600.
And it appreciates at a rate of 3.97% each year.
And we want to find the value of the art after 10 years.
We can write an exponential function to model the situation. The standard exponential function is given by:
[tex]f(t)=a(r)^t[/tex]Where t is the time in years.
Since it appreciates at a rate of 3.97% each year, the value after each year will be (100% + 3.97%) or 103.97%.
103.97% = 1.0397. So, r = 1.0397:
[tex]f(t)=a(1.0397)^t[/tex]Our a is the initial value. Therefore:
[tex]f(t)=600(1.0397)^t[/tex]Then the value of the piece of art after 10 years is:
[tex]f(10)=600(1.0397)^{10}=885.58793\approx885.59[/tex]Hence, It will be worth about £885.59 after 10 years.

Complex numbers can be written in two forms:

In this case we are given these last two quantities and we have to find a and b. One way to do this is recalling an important property of the exponential expression above:
[tex]e^{i\theta}=\cos \theta+i\sin \theta[/tex]Then the exponential form of a number is equal to:
[tex]z=r\cdot e^{i\theta}=r\cdot(\cos \theta+i\sin \theta)=r\cos \theta+i\cdot r\sin \theta[/tex]And since we are talking about the same number then this expression must be equal to that given by a and b:
[tex]a+i\cdot b=r\cos \theta+i\cdot r\sin \theta[/tex]Equalizing terms without i and those with i we have two equations:
[tex]\begin{gathered} a=r\cos \theta \\ b=r\sin \theta \end{gathered}[/tex]Now let's use the data from the exercise:

Answers
Answer:
• The number of first-class tickets bought = 3
,• The number of coach tickets bought =7
Explanation:
Let the number of first-class tickets bought = x
Let the number of coach tickets bought = y
A total of 10 people took the trip:
[tex]\implies x+y=10[/tex]Her total budget for the trip's airfare = $4220.
[tex]\implies200y+940x=4220[/tex]Next, solve the two equations simultaneously:
[tex]\begin{gathered} x+y=10\implies x=10-y \\ 940x+200y=4220 \end{gathered}[/tex]Substitute x into the second equation:
[tex]\begin{gathered} 940(10-y)+200y=4220 \\ 9400-940y+200y=4220 \\ 9400-740y=4220 \\ 9400-4220=740y \\ 5180=740y \\ \frac{5180}{740}=y \\ y=7 \end{gathered}[/tex]Recall: x=10-y

For her cell phone plan heather pays 30 dollars per month plus 0.05 per text. She wants to keep her cell phone bill under 60 dollars per month. Which inequality represents the number of texts t heather can send each month while staying within her budget?
Answers
The inequality represents the number of texts t heather can send each month while staying within her budget is t<600.
Given, heather pays 30 dollars per month plus 0.05 per text.
She wants to keep her cell phone bill under 60 dollars per month.
hence texts she can send = 0.5 × 600
= $30
hence for $30 heather can text upto 600 texts.
so, cell phone plans + text
= $30 + $ 30
= $60
so, the inequality represents the number of texts t heather can send each month while staying within her budget is t<600
Hence the inequality is t<600
