Final answer:

To find the range of a rational function with a slant asymptote, you first find the asymptote by long division. Then by examining the behavior of the function near the vertical asymptotes by plugging in values, you determine the limits of the range. Generally, the range is all real numbers except where interrupted by the asymptotes.

Explanation:

To find the range of a rational function with a slant asymptote, you need to first find the slant asymptote by dividing the numerator by the denominator using long division. When you perform the division, if the degree of the numerator is one more than the degree of the denominator, then the quotient (excluding the remainder) will be the equation for the slant asymptote.

Next, you need to explore the behavior of the function on the left and right of the vertical asymptotes, this is done by substituting values just to the left and right of each vertical asymptote into the function and observing the outputs.

If the function approaches negative infinity, the lower limit of the range will be negative infinity. If the function approaches positive infinity, the upper limit of the range will be positive infinity.

So, the range of the function is typically all real numbers except for the values that are 'cut out' by the asymptotes.

Final answer:

To determine the range of a rational function with a slant asymptote, graph the function, analyze for vertical and horizontal asymptotes, discontinuities, and observe its long-term behavior relative to the slant asymptote. The range typically includes all real numbers except for values excluded due to vertical asymptotes or holes.

Explanation:

To find the range of a rational function with a slant asymptote, follow these steps:

Graph the rational function to observe its behavior and identify the slant asymptote.Analyze the graph to see where the function's output values (y-values) lie as the input (x-values) become very large or very small.Identify any horizontal or vertical asymptotes, as these will also affect the range.Look for any discontinuities such as holes or vertical asymptotes that might create gaps in the range.Combine all this information to determine the set of all possible y-values the function can attain, remembering that the function will approach but not touch the slant asymptote.

Considering the slant asymptote, the function will continue to increase or decrease without bound in at least one direction, unless there is another horizontal asymptote. Therefore, the range can often be all real numbers, except possibly excluding specific values or intervals due to vertical asymptotes or holes.

Correct Answer:
First Option

Let the first integer be n.
Since the integers are consecutive, the integer next to n will be n+1
and so the third integer will be n+2

Therefore, the three integers are:
n , n +1, n+2

Their sum is 75. So we can write the equation as:

n + (n+1) + (n+2) = 75

This equation can be used to find n. After finding n, we can find the next two integers by finding (n+1) and (n+2)

Step-by-step explanation:

Begin by adding 4.9x to both sides.
1.3> 11.1 + 4.9x This way you never have to remember to turn the > into < when dividing by a minus.

Subtract 11.1 from both sides
-9.8 < 4.9x Divide by 4.9
-9.8 / 4.9 < x
-2 < x

To solve the inequality -4.9x + 1.3 > 11.1, subtract 1.3 from both sides and then divide by -4.9, flipping the inequality sign to get x < -2. The solution set is x < -2.

To solve the inequality -4.9x + 1.3 > 11.1, follow these steps:

Subtract 1.3 from both sides to isolate the term with x:
-4.9x > 11.1 - 1.3
-4.9x > 9.8Divide both sides by -4.9 and remember to flip the inequality sign because you are dividing by a negative number:
x < -9.8 / -4.9
x < -2

The solution set for the inequality is x < -2.

 Remember that the first derivative of a function is the slope of the function at any specified point. We've been told that f(0) = -5 and that f'(x) is always less than or equal to 3. So let's look at the available options and see what the average slope would have to be in order to get the specified value of f(2).
 A) -10: (-10 - -5)/(2 - 0) = -5/2 = -2.5
 B) -5: (-5 - -5)/(2 - 0) = 0/2 = 0
 C) 0: (0 - -5)/(2 - 0) = 5/2 = 2.5
 D) 1: (1 - -5)/(2 - 0) = 6/2 = 3
 E) 2: (2 - -5)/(2 - 0) = 7/2 = 3.5 
 Now taking into consideration the mean value theorem, the value of the function f'(x) has to have the value equal to the average slope between the two points at at least one point between the two given values. For options A, B, C, and D it's possible for f'(x) to return values that make that slope possible. However, for option E, the mean value theorem indicates that f'(x) has to have the value of 3.5 for at least 1 point between x=0 and x=2. And since we've been told that f'(x) is less than or equal to 3 for all possible values of x, that is in conflict and f(2) can not have the value of 2.

Final answer:

Using the Mean Value Theorem, we can determine the possible values for f(2) which is D) 1

Explanation:

To find the possible values for f(2), we can use the Mean Value Theorem. Taking into consideration the mean value theorem, the value of the function f'(x) has to have the value equal to the average slope between the two points at at least one point between the two given values.

Since f(0) = -5 and f'(x) is less than or equal to 3 for all x, we know that f(2) must lie between -5 and -5 + 3(2) = 1.

Therefore, 1 is not a possible value for f(2), making the correct answer choice D) 1.

[tex]P[/tex] is the initial investment  
[tex]r[/tex] is the interest rate in decimal form 
[tex]t[/tex] is the number of years 
With this formula we will find the final amount Azhar's investment after 7 years. We know from our problem that [tex]P=10000[/tex], [tex]r= \frac{2}{100}=0.02 [/tex], and [tex]t=7[/tex]. Lets replace those values in our formula to find [tex]A[/tex]:
[tex]A=10000(1+(0.02)(7))[/tex]
[tex]A=10000(1.14)[/tex]
[tex]A=11400[/tex]

Now, since Sarah is investing in a compound interest account, we are going to use the compound interest formula: [tex]A=P(1+ \frac{r}{n})^{nt} [/tex]
where
[tex]A[/tex] is the final amount after [tex]t[/tex] years
[tex]P[/tex] is the initial investment 
[tex]r[/tex] is the interest rate in decimal form
[tex]n[/tex] is the number of times the interest is compounded per year
[tex]t[/tex] is the number of years
Notice that we know from our problem that after 7 years their investments are worth the same amount, so [tex]A=11400[/tex]. We also know that [tex]P=10000[/tex], [tex]r= \frac{x}{100} =0.01x[/tex], and [tex]t=7[/tex]. Since the interest are compounded per year, [tex]n=1[/tex]. Lets replace all the vales in our compound interest formula and solve for [tex]x[/tex] to find our rate:
[tex]11400=10000(1+ \frac{0.01x}{1} )^{(1)(7)} [/tex]
[tex] \frac{11400}{10000} =(1+0.01x) ^{7} [/tex]

[tex]x= \frac{ \sqrt[7]{1.14}-1 }{0.01} [/tex]

We can conclude that the interest rate of Sarah's investment is approximately 1.89%, so x=1.89%.

The product of 9 multiplied by 1/5 is 1.8, which is less than 9 because multiplying by a fraction between 0 and 1 reduces the original number.

To find the answer, you simply multiply 9 by 1/5. When you multiply a whole number by a fraction less than 1, the product is always less than the original whole number because you are taking a part of it. So, 9 × 1/5 equals 9/5 or 1.8, which is definitely less than 9.

In mathematics, when you multiply a number by a fraction between 0 and 1, the result will be smaller than the original number. This is similar to taking a part of something. On the other hand, when you multiply a number by a fraction greater than 1 or by a whole number greater than 1, the result is greater than the original number because you are effectively adding the number to itself multiple times.

Answer: $99

Step-by-step explanation:

Yvette's estimated cost for buying 9.3 yards of velvet fabric at $11.49 per yard is approximately $106.86. This is calculated by multiplying the price per yard with the number of yards. An initial rough estimate of $103.50 was also considered before doing a precise calculation.

To calculate the estimated cost of the velvet fabric Yvette buys, you need to multiply the price per yard by the number of yards:

Price per yard = $11.49

Number of yards = 9.3

Estimated cost = $11.49 × 9.3

Let's break it down step-by-step:

First, estimate the two numbers. $11.49 is close to $11.50, and 9.3 is close to 9. Then, multiply: 11.50 × 9 = $103.50.Now calculate more precisely: 11.49 × 9.3 = 106.857 but rounded to two decimal points, it's $106.86.

So, Yvette's estimated cost of the fabric is approximately $106.86.

It would just be 4a² as the LCD, because the first fraction can have the denominator easily multiplied by 4a to make 4a²

The equation you have provided is correct:

A(t)=P(1+r/n)^nt

Where P = principal amount

              r = interest rate

              n = number of times the amount is compounded in a year

              t = time in years

The value of n is 12 since it is compounded monthly.

Substituting the amount to the formula:

A(t) = $300 ( 1 + 4%/12)^(12)(8)

A(t) = $300 (1 + 0.003333)^96

A(t) = $300 (1.376351)

A(t) = $412.91

x = 21 inches 
length of tablet - 21 inches 
width of tablet - 14 inches 

Answer:

Length = 16 inches and width = 9 inches

Step-by-step explanation:

The perimeter of a rectangle table = 50 inches

Rectangle table has equal sides of length and equal sides of width.

Let the length of the table be x.

It is given in the question that the table is 7 inches less wide than it is long.

So width of the table = x - 7

Perimeter = 2(length) + 2(width)

Perimeter = 2(x) + 2(x-7) = 50

                = 2x + (2)(x) + (2)(-7) = 50

                = 2x + 2x + (-14) = 50

                = 4x -14 = 50

                =  4x = 64

                 x = 16

Length = 16 inch Width = 16 - 7 = 9 inches

perimeter = 2(16) + 2(9) = 50 inches

The Bible, a book that is considered the perfect word of a perfect god tells us what the value of Pi is. Let's see verse 1 Kings 7:23
 He also melted a sea of ​​ten cubits from one side to the other, perfectly round; Its height was five cubits, and a cord of thirty cubits encircled it.

 These are a list of specifications for the great temple of King Solomon, built about 950 BCE, and his interest here is that it gives a value of π = 3. If we divide 30 cubits between 10 cubits (which are the measures mentioned in written radical) gives us exactly 3.

 We know that the length of the circumference is calculated l = 2 · π · r; Since 2 · r is the diameter, it can also be said that

 circumference = diameter × π

 If we go back to what the Bible says, the diameter is 5 meters and the circumference of 15:

 circumference = diameter × π -> 15 = 5 × π

 with which the value of π is 3.

 This calculation of Pi is a bad approximation to the real value. The figure of 3 in the Bible compared with the real one which is 3.1416 ... indicates an error of about 6%.

The period of sine is 2π.

Answer:

Option B. 4

Step-by-step explanation:

By the table mentioned by you in the comments that the correct table is

x(miles)   2        5        8     12

y(cost)   8.5   15.25    22    31

As we know that the standard equation of a linear function is represented as

y = mx + c

For the points (2, 8.5) and (5, 15.25)

[tex]Slope(m)=\frac{15.25-8.5}{5-2}=\frac{6.75}{3}=2.25[/tex]

y = 2.25x + c

This function passes through (2, 8.5)

8.5 = 2.25×2 + c

c = 8.5 - 4.5 = 4

Therefore, y- intercept of the function will be option B. 4.

The y-intercept of this line is (4). Therefore, the estimated y-intercept of the function represented by the given data is 4.

To find the y-intercept of the function from the provided table, we look for the point where (x = 0), which represents the cost when no miles are traveled.

However, in the given table, there is no entry for \(x = 0\), which means we don't have a direct value for the y-intercept from the given data.

To estimate the y-intercept, we can use the concept of linear interpolation.

We can assume that the relationship between miles traveled and cost is linear, so we can find the slope of the line passing through two consecutive points and use it to estimate the cost when (x = 0).

Using the points (2, 8.5) and (5, 15.25) from the table:

[tex]\[ \text{Slope} = \frac{{15.25 - 8.5}}{{5 - 2}} = \frac{6.75}{3} = 2.25 \][/tex]

Now, we can use the slope and one of the points to find the y-intercept using the point-slope form of the equation of a line: [tex]\(y - y_1 = m(x - x_1)\).[/tex] Let's use the point (2, 8.5):

y - 8.5 = 2.25(x - 2)

y - 8.5 = 2.25x - 4.5

y = 2.25x + 4

The y-intercept of this line is (4). Therefore, the estimated y-intercept of the function represented by the given data is [tex]\(\boxed{4.00}\)[/tex].

To find all possible values for θ if 0° < θ < 360° and tanθ = -1, we need to determine in which quadrants the tangent function is negative and then find the specific angles in those quadrants where the tangent equals -1.

The tangent function is negative in the second and fourth quadrants. Since tan(45°) = 1, we are looking for angles where the reference angle is 45° and the tangent is negative.

In the second quadrant, the angle that meets these criteria is 180° - 45° = 135°.

In the fourth quadrant, the angle that meets these criteria is 360° - 45° = 315°.

Therefore, the correct values for θ are:

c. 135°

e. 315°

The correct answer is [tex]135^{0}[/tex], [tex]225^{0}[/tex]

To find all possible values of θ if 0° < θ < 360° and tan θ = -1, we need to consider the values of θ in the different quadrants where the tangent function is negative.

In the first quadrant (0° < θ < 90°), the tangent function is positive, so there are no solutions in this range.

In the second quadrant (90° < θ < 180°), the tangent function is negative, and tan(135°) = -1.

In the third quadrant (180° < θ < 270°), the tangent function is also negative, and tan(225°) = -1.

In the fourth quadrant (270° < θ < 360°), the tangent function is positive, so there are no solutions in this range.

Therefore, the possible values of θ satisfying the given conditions are:

[tex]\theta = 135^\circ and \theta = 225^\circ[/tex]

Analyzing the given options:

a. [tex]-225^\circ[/tex] is not a solution, as it lies outside the given range of 0° < θ < 360°.

b. [tex]-45^\circ[/tex] is not a solution, as the tangent function is positive in the fourth quadrant.

c. [tex]135^\circ[/tex] is a solution, as tan(135°) = -1.

d. [tex]225^\circ[/tex] is a solution, as tan(225°) = -1.

e. [tex]315^\circ[/tex] is not a solution, as the tangent function is positive in the fourth quadrant.

Therefore, the correct options are c. 135° and d. 225°.

The answer for the blank is 0.003

This is the slope value, which is the number in front of the x in the least squares regression line. Each time x increases by 1, y increases by 0.003

This is the predicted y value of course. 

48 - 3 = 45.
45 divided by 6 = 7.5
That means that the width is 7.5 and the length is 18. Hope it helps! :)

The greatest common factor is what both terms have in common. 
7 and 8 have nothing in common.
ab and b^3 have b in common.
The greatest common factor is b.

I believe the answer would be Whole Numbers

10(cos(4pi/3) + i sin(4pi/3)) To multiply complex numbers in trigonometric form, you simply multiply the radii and add the thetas. We have: z1=5(cos(pi/2)+i sin(pi/2)) z2=2(cos(5pi/6)+i sin(5pi/6)) The radii for the above 2 numbers are 5 and 2. So the result will have a radius of 5*2 = 10. The thetas are pi/2 and 5pi/6, so the new theta will be pi/2 + 5pi/6 = 3pi/6 + 5pi/6 = 8pi/6 = 4pi/3. So the answer is: 10(cos(4pi/3) + i sin(4pi/3))
