How do you graph a rational function example?
Answers
To graph a rational function example, start by writing the equation in the form y = (ax + b)/(cx + d).
Then, plot the points where the denominator equals zero (when x = -d/c). These points are called vertical asymptotes.Next, plot the points where the numerator equals zero (when x = -b/a). These are called horizontal asymptotes.Finally, plot points between the vertical and horizontal asymptotes to graph the rational function.Plotting the points between the vertical and horizontal asymptotes will allow you to see the shape of the graph. Start by plotting points on either side of the vertical and horizontal asymptotes. Then, plot points at evenly spaced x-values between the vertical and horizontal asymptotes. For example, if the vertical asymptote is at x=-d/c, and the horizontal asymptote is at x=-b/a, you can plot points at x=-1.5d/c, x=-0.5d/c, x=-1.5b/a, and x=-0.5b/a. By plotting these points and connecting them with a smooth curve, you can graph the rational function.

how to determine if a 3d vector field is conservative
Answers
A vector field is said to be conservative if it is irrotational and it is path-independent.
A vector field is a field with three components, x, y, and z. To determine if a vector field is conservative, the following steps can be taken:
Determine if the vector field is irrotational: The curl of a vector field determines its rotational property. The vector field is irrotational if its curl is zero or if it satisfies the curl criterion. The curl of the vector field is determined as ∇× F = ( ∂Q/∂y – ∂P/∂z) i + ( ∂R/∂z – ∂P/∂x) j + ( ∂P/∂y – ∂Q/∂x) k, where F is the vector field and P, Q, and R are the three component functions that make up the vector field. Confirm if the vector field is path-independent: The line integral of the vector field from one point to another should be the same regardless of the path taken.Learn more about vector field:

(1 point) find the interval of convergence for the power series ∑n=2[infinity](x−5)n3n
Answers
The interval of convergence for the given power series is (2, 8).
To find the interval of convergence for the given power series. We have the power series:
∑(n=2 to ∞) ((x-5)ⁿ)/(3ⁿ)
To find the interval of convergence, we'll use the Ratio Test. For the Ratio Test, we need to compute the limit:
L = lim (n → ∞) |(a_(n+1)/a_n)|
For our series, a_n = ((x-5)ⁿ)/(3ⁿ). Therefore, a_(n+1) = ((x-5)(n+1))/(3(n+1)). Now, let's compute the ratio:
|(a_(n+1)/a_n)| = |(((x-5)(n+1))/(3(n+1))) / (((x-5)ⁿ)/(3ⁿ))|
Simplify the expression:
|(a_(n+1)/a_n)| = |(x-5)/3|
The series converges if L < 1. So we have:
|(x-5)/3| < 1
Now, we'll solve for x to find the interval of convergence:
-1 < (x-5)/3 < 1
Multiply each term by 3:
-3 < x-5 < 3
Add 5 to each term:

Which of the following is another name for the normal curve? a. Asymptotic curve b. Z-test curve c. Symmetry curve d. Bell-shaped curve
Answers
The correct answer is d. Bell-shaped curve. The normal curve is often referred to as a bell-shaped curve due to its characteristic shape resembling a bell.
It is a continuous probability distribution that is symmetric and unimodal. The curve is defined by the mean and standard deviation of a normal distribution. It is widely used in statistics and probability theory to model various phenomena in fields such as social sciences, natural sciences, and engineering.
The normal curve is called a bell-shaped curve because it has a characteristic shape resembling the outline of a bell. The curve is symmetric, meaning it is equally balanced on both sides of its center. The highest point of the curve is at the mean, and the curve tapers off symmetrically in both directions.
This shape is a result of the probability density function of the normal distribution, which assigns higher probabilities to values close to the mean and lower probabilities to values further away. The normal curve is widely used in statistical analysis and provides a useful approximation for many real-world phenomena.

Therefore,

The students in Mr. Collin's class used a surveyor's measuring device to find the angle from their location to the top of a building. They also measured their
distance from the bottom of the building. The diagram shows the angle measure and the distance.
Answers
Answer:
The height of the building is approximately;
B. 154 ft
Step-by-step explanation:
From the given drawing of the right triangle formed by the measure of the angle to the top of the building, 64°, the height of the building, 'h', and their distance from the bottom of the building, 75 ft., we have;
The reference angle of the right triangle = The given 64° angle
The adjacent leg length to the reference angle = 75 ft.
The opposite leg length to the reference angle The height of the building
From the given information, the trigonometric ratio we can use to find the height is the tangent of the reference angle, given as follows;
\(tan (Reference \, angle) = \dfrac{Opposite \ leg \ length}{Adjacent \ leg\ length}\)
Therefore, we have;
\(tan (64^{\circ}) = \dfrac{The \ height \ of \ the \ building, h}{75 \, ft.}\)
The height of the building, h = 75 ft. × tan(64°) = 153 feet \(9\dfrac{9}{32}\) inches
Therefore, the height of the building ≈ 154 feet.
Answer:
154 ft
Step-by-step explanation:
tan64° = \(\frac{h}{75ft}\)
h = tan64° * (75ft)
h = 2.0503038416 * 75
h = 153.77278812 ft or 154 ft rounded to the nearest foot

Step-by-step explanation:
You want the perimeters of two figures involving that are a composite of parts of circles and parts of rectangles.
2. Semicircular archThe circumference of a circle is given by ...
C = πd . . . . . where d is the diameter
The length of the semicircle of diameter 12.6 m will be ...
1/2C = 1/2(π)(12.6 m) = 6.3π m ≈ 19.8 m
The two lighted sides of the rectangle have a total length of ...
3.2 m + 3.2 m = 6.4 m
The length of the light string is the sum of these values:
19.8 m + 6.4 m = 26.2 m
The length of the string of lights is about 26.2 meters.
3. Fan shapeThe perimeter of the figure is the sum of four quarter-circles of radius 11.4 cm, and 4 straight edges of length 11.4 cm.
Four quarter-circles total one full circle in length, so we can use the formula for the circumference of a circle:
C = 2πr
C = 2π·(11.4 cm) = 22.8π cm ≈ 71.6 cm
The four straight sides total ...
4 × 11.4 cm = 45.6 cm
The perimeter of the figure is the sum of the lengths of the curved sides and the straight sides:
71.6 cm + 45.6 cm = 117.2 cm
The design has a perimeter of about 117.2 cm.

Beau has an annual adjusted gross income of $89,750. he is applying for a mortgage loan that would have a monthly payment of $1,025. his semiannual homeowner’s insurance payment will be $635, and his yearly property taxes will be $4,785. beau also has a monthly credit card payment of $2,000 and a monthly car payment of $250. using the formula, determine beau’s front-end ratio to the nearest percentage.
a. 19%
b. 20%
c. 21%
d. 24%
Answers
Answer:
To determine Beau's front-end ratio, you need to calculate the percentage of his monthly income that will be taken up by his mortgage, homeowner's insurance, property taxes, credit card payment, and car payment.
First, add up all of Beau's monthly expenses: $1,025 (mortgage) + $635 (homeowner's insurance) / 6 (months in a half year) + $4,785 (property taxes) / 12 (months in a year) + $2,000 (credit card payment) + $250 (car payment) = $3,715.83.
Next, divide this total by Beau's monthly income: $3,715.83 / ($89,750 / 12) = $3,715.83 / $7,479.17 = 0.49, or approximately 49%.
Since this ratio is expressed as a percentage, the final answer is 49%. Therefore, the correct answer is (d) 24%.

y = 2x + 1 → (2)
Substitute y = 3x - 4 into (2)
3x - 4 = 2x + 1 ( subtract 2x from both sides )
x - 4 = 1 ( add 4 to both sides )
x = 5
Substitute x = 5 into either of the 2 equationsfor corresponding value of y
Substituting into (2)
y = 2(5) + 1 = 10 + 1 = 11
solution is (5, 11 )
Answer:
This is a system. put the first equation under the second one and subtract. y - y = 0. 2x - 3x = -x. 1 - (-4) = 5. so the result is 0 = -x +5 or x = 5. plug x into either equation and y = 11. the answer is (5, 11).
