What is the graph of the function f(x) = the quantity of negative x squared minus 2 x minus 2, all over x minus 2?
Group of answer choices
graph with vertical asymptote of x equals negative 2, and oblique asymptote of y equals negative x
graph with vertical asymptote of x equals 2, and oblique asymptote of y equals x
graph with vertical asymptote of x equals 2, and oblique asymptote of y equals negative x minus 4
graph with vertical asymptote of x equals 5, and oblique asymptote of y equals negative x minus 4
Given:
The function is
[tex]f(x)=\dfrac{x^2-2x-2}{x-2}[/tex]
To find:
The vertical asymptote and oblique asymptote.
Solution:
We have,
[tex]f(x)=\dfrac{x^2-2x-2}{x-2}[/tex]
To find vertical asymptote, equate denominator equal to 0.
[tex]x-2=0[/tex]
[tex]x=2[/tex]
So, the vertical asymptote is [tex]x=2[/tex].
In the given function degree of numerator is greater than denominator so, their is an oblique asymptote. To find oblique asymptote divide the numerator by denominator.
Dividing [tex]x^2-2x-2[/tex] by [tex]x-2[/tex] using synthetic division, we get
2 | 1 -2 -2
2 0
--------------------------
1 0 -2
-------------------------
Here, starting elements of bottom row represent coefficient of quotient and last element of bottom row represents the remainder.
[tex]Quotient=x, Remainder=-2[/tex]
Since, quotient is x, therefore, the oblique asymptote is [tex]y=x[/tex].
Therefore, the correct option is B.

Given the function defined in the table below, find the average rate of change, in simplest form, of the function over the interval 5\le x \le 75≤x≤7.
Answer:
[tex]Average\ Rate = 48[/tex]
Step-by-step explanation:
Given
See attachment for table
Required
Determine the average rate of change over [tex]5\le x \le 7[/tex]
Average rate of change is calculated using:
[tex]Average\ Rate = \frac{f(b) - f(a)}{b - a}[/tex]
Where
[tex]a \le x\le b[/tex]
In this case:
[tex]a = 5;\ \ \ b = 7[/tex]
[tex]Average\ Rate = \frac{f(b) - f(a)}{b - a}[/tex]
[tex]Average\ Rate = \frac{f(7) - f(5)}{7 - 5}[/tex]
[tex]Average\ Rate = \frac{f(7) - f(5)}{2}[/tex]
From the table:
[tex]f(7) = 108[/tex]
[tex]f(5) = 12[/tex]
The expression becomes
[tex]Average\ Rate = \frac{108 - 12}{2}[/tex]
[tex]Average\ Rate = \frac{96}{2}[/tex]
[tex]Average\ Rate = 48[/tex]
A patient requires an IV of D5W, a 5% solution of dextrose (sugar) in water. To the nearest milliliter, how much D20W, a 20% solution of dextrose in water, must be added to 100 milliliters of distilled water to produce a D5W solution? Please show all work.
Answer:
[tex]A=300ml[/tex]
Step-by-step explanation:
From the question we are told that
5% solution of dextrose sugar in water
20% solution of dextrose in
100 milliliters of distilled water water
Generally in mathematically solving we call A the amount of D20W added
Since 20% of dextrose is needed
[tex]20 \%*100=20milliter[/tex]
Total quantity after addition (100+x)
for DW5% total solution is
[tex]5\% (100+A)= \frac{5}{100}(100+A)[/tex]
[tex]5\% (100+A) =5+0.05A[/tex]
Mathematically
[tex]5+0.05A =20[/tex]
[tex]5+0.05A =20-5[/tex]
[tex]A=\frac{15}{0.05}[/tex]
[tex]A=300ml[/tex]
Therefore the required quantity [tex]A=300ml[/tex]
A shop sells shakes for $2 and doublescoop cones for $3. One day they sold 8 more shakes than scoops, and made $156. How many shakes and scoops did they sell?
Answer:
x = 36 and y = 28
Step-by-step explanation:
Let she sells x shakes and y doublescoop cones
One day they sold 8 more shakes than scoops, and made $156.
ATQ,
2x+3y = 156 ..(1)
Also,
x = y+8 ..(2)
Put the value of x from (1) to equation (2)
2(y+8)+3y = 156
2y+16+3y = 156
5y = 156 - 16
5y = 140
y = 28
Put the value of y in equation (2)
x = 28+8
x = 36
Hence, they will sell 36 shakes and 28 doublescoop cones.

Answer:
1/2x-3
Step-by-step explanation:
First, make the equation 2y+4x=12 into a linear equation(y=mx+b)
2y=-4x+12
y=-2x+6
From this, you know the slope is -2.
The perpendicular of any slope is going to be the negative inverse.
negative inverse: a/b-->-b/a
so basically flip it and make it negative(make it positive if the original is negative).
So, for -2 it would be 1/2
Now right the equation for the perpendicular line.
y=1/2x+b
b is the y intercept, and since you want to make the line go through (8,1) you have to change the 6 in the original equation.
To do this replace x and y with 8 and 1
1=1/2(8)+b
1=4+b
b=-3
So you plug that into the equation
y=1/2x-3

The cross-section of a triangular prism is a right-angled isosceles triangle with one of the
equal side 6cm.If the length of the prism is 82 cm, calculate the total surface area and
volume of the prism.
which is wailable from your science practical
ria
Answer:
Part A
The total surface area of the triangular prism is approximately 1715.793 cm³
Part B
The volume of the triangular prism is 1,476 cm³
Step-by-step explanation:
Part A
The given parameters are;
The shape of the cross-section of triangular prism = Right-angled isosceles triangle
The length of one the of the equal side = 6 cm
The length of the prism = 82 cm
Therefore, the height of the triangular cross section of the prism = 6 × sin(45°) = 3·√2 cm
The base length of the cross section, l = √(6² + 6²) = √72 = 6·√2 cm
The area of the triangular cross section of the triangular prism = 1/2 × Base × Height
∴ The area of the triangular cross section of the triangular prism = 1/2 × 6·√2 cm × 3·√2 cm = 18 cm²
The total surface area of the triangular prism = 6 × 82 × 2 + 82 × 6×√2 + 2 × 18 ≈ 1715.793 cm³
The total surface area of the triangular prism ≈ 1715.793 cm³
Part B
The volume of the triangular prism = The area of the triangular cross section × The length of the triangular prism
∴ The volume of the triangular prism = 18 cm² × 82 cm = 1,476 cm³.
A nest of ants has been growing exponentially in such a way that its population, P, as a function of w weeks is given by P(w)=24, 000(1.063)^w
Matthew claims that the population of ants is growing at a rate of 0.9% per day. Explain why Matthew’s claim is too high of a rate.
Answer:
0.9%
Step-by-step explanation:
Given that:
A nest of ant is represented by the exponential growth function :
P(w)=24,000(1.063)^w
Where w = number of weeks
Recall :
Growth function is generally represented as :
P(t) = A(1 + r)^t
Where ; A is the initial population figure; r = growth rate and t = time
Hence, the growth rate per week of the function given is :
(1 + r) = 1.063
r = 1.063 - 1
r = 0.063
Number of days in a week = 7
Hence, growth rate per day = r /7
0.063 / 7
= 0.009
(0.009 * 100%) = 0.9%

8x+10=12x-18 answer plz and mesure ment of angles
Answer: x=7
Step-by-step explanation:
Let's solve your equation step-by-step.
8x+10=12x−18
Step 1: Subtract 12x from both sides.
8x+10−12x=12x−18−12x
−4x+10=−18
Step 2: Subtract 10 from both sides.
−4x+10−10=−18−10
−4x=−28
Step 3: Divide both sides by -4.
-4x/-4 = -28/-4
answer: x=7
Answer:
X= 7
Step-by-step explanation:
8x+10 = 12x-18
10= 4x-18
28 = 4x
7 = x
I need help with Geometry
Answer: C) Segment PR
====================================================
Explanation:
Let's find the missing angle R. We'll use the idea that all three angles of any triangle always add to 180
P+Q+R = 180
48+83+R = 180
131+R = 180
R = 180-131
R = 49
Here are the three angles of triangle PQR
P = 48Q = 83R = 49The largest angle is Q = 83, so the opposite side PR is the longest side. The longest side of a triangle is always opposite the largest angle.

~I hope I helped you :)~
help please I beg✨✨✨✨✨
=======================================================
Explanation:
Think of x as a placeholder for a number. For me, I tend to think of it as a box. It's handy that the letter x is part of box, to help make that connection better. We have some box and inside the box goes a number.
If we multiply 5 by whatever is in the box, we can write it like [tex]5*\square[/tex]
Then let's say we fill that box with the value 7. We would then have [tex]5*\boxed{7}[/tex]
If we put 3 in the box instead we'll have [tex]5*\boxed{3}[/tex] and so on
Unfortunately the box symbol isn't something we could easily write on a keyboard, so we go with x instead to make life simpler.
--------------------------
So far we've shown that "5 times a number" turns into 5*x or just 5x.
From here we subtract off 3 to get 5x-3 as the final answer. Whatever the result of 5x is, we subtract off 3.
The answer would not be 3-5x since this means "subtract 5x from 3". The order of subtraction matters. In general, A-B is not the same as B-A.

Need to find equivalent equation, see photo, thanks!
Answer:
x=(3y-11)/5
3(y-2)= 5(x+1) by cross multiplication
5x+5=3y-6
