How does the graph of g(x) = - 1/x compare to the graph of f(x) = 1/x?
Answer:
The answer is B) g(x) is shift 5 units to the right and 2 units up from f(x).
Step-by-step explanation:
The equation that is given in this item can be written for clarity as follows:
g(x) = 1/(x - 5) + 2
It can be seen that the x-component is subtracted with 5 and the g(x) which would lie in the y-axis is added with two. This suggests that the graph of this equation is shifted to the right by 5 units and upwards by 2 units compared to the graph of the parent function.
The Graph for both function is attached below.

Answer:
A
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = \(\frac{19}{x^3}\) ( multiply both sides by x³ )
x³y = 19 ( divide both sides by y )
x³ = \(\frac{19}{y}\) ( take the cube root of both sides )
x = \(\sqrt[3]{\frac{19}{y} }\)
Change y back into terms of x, then
\(f^{-1}\) (x) = \(\sqrt[3]{\frac{19}{x} }\) = \(\frac{\sqrt[3]{19} }{\sqrt[3]{x} }\) → A

plsss help!
The measure of the frame in feet of the length and width are 3.667 feet and 2.125 feet respectively.
What is the unitary method?The unitary method is a method in which you find the value of a unit and then the value of a required number of units.
Given here: The measure of the frame is 8.5 inches and 11 inches
a) if the frame is 4 papers long then we have the length of the frame as
11×4=44 inches (since he lays the paper along the edge of frame)
We know 1 inch= 0.0833 foot
Thus 44 inches= 3.66667 foot
b) Again if he lays the paper along the short edge than the width of the frame is 3×8.5=25.5 inches
∴25.5 inches= 2.125 feet
Hence, The measure of the frame in feet of the length and width are 3.667 feet and 2.125 feet respectively.

Points A and B are on opposite sides of a lake. Another point, C. is 94.4 meters from Angle A. The measure of Angle A is 72° and the measure of Angle C is 30°. Find the distance between A and B.
To find the distance between points A and B, we can use trigonometry and the given information.
Let's label the distance between A and B as "d". We know that point C is 94.4 meters away from point A. From angle A, we have the measure of 72°, and from angle C, we have the measure of 30°.
Using trigonometry, we can use the tangent function to find the value of "d".
tan(72°) = d / 94.4
To solve for "d", we can rearrange the equation:
d = tan(72°) * 94.4
Using a calculator, we can evaluate the expression:
d ≈ 4.345 * 94.4
d ≈ 408.932
Therefore, the distance between points A and B is approximately 408.932 meters.
An organization advocating for healthcare reform has estimated the average cost of providing healthcare for a senior citizen receiving Medicare to be about $13,000 per year. The article also stated that, with 90% confidence, the margin or error for the estimate is $1,000. Determine the resulting 90% confidence interval for the average cost for healthcare of a senior citizen receiving Medicare.
Using the definition of a confidence interval, it is found that the 90% confidence interval for the average cost for healthcare of a senior citizen receiving Medicare is ($12,000, $14,000).
A confidence interval is the sample mean plus/minus the margin of error.
In this problem, the sample mean is of $13,000.The margin of error is of $1,000.Hence:
$13,000 - $1,000 = $13,000
$13,000 + $1,000 = $14,000
The interval is ($12,000, $14,000).

The average rate of change of the function is found as 1.
What is termed as the rate of change of function?The rate of change function has been described as the rate during which one quantity changes in relation to another. The rate of change from y coordinates to x coordinates can be calculated as Δy/ Δx = (y2 - y1)/ (x2 - x1 ).For the given question;
The function is given by the equation;
g(x) = -x² - 9x + 27
The interval of the function lies as;
-9 ≤ x ≤ -1.
Let,
a = -1 ans b = -9
Then,
g(a) = g(-1), Put x = -1 in the function.
g(-1) = -(-1)² - 9(-1) + 27
g(-1) = 35
Now, g(b) = g(-9), Put x = -9 in the function.
g(-9) = -(-9)² - 9(-9) + 27
g(-9) = 27
Thus, the average rate of change of the function is-
Average rate of change = [g(a) - g(b)]/[a - b]
= [35 - 27]/[-1 + 9]
= 8/8
= 1
Thus, the average rate of change of the function is found as 1.

Find the value of each variable in the parallelogram. Round your answers to the nearest tenth, if necessary. G a = (46) K (3a +19) b H 56°
The value of every variable in the parallelogram is: a = 9 HK = 27.0 GK = 46 G = 63.5°
What do you mean by Parallelogram ?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.These shapes include squares, rectangles, rhombuses, and rhomboids. All of these shapes have four sides, four corners, and four angles
We know that sides of a parallelogram are parallel and congruent, as opposite angle
According to question that GA equals HK, as:
46 is equal to 3a plus 19 When we subtract 19 from both sides, we get:
27 x 3a is the result of dividing both sides by 3:
we know that opposite angles in a parallelogram are congruent, we can use a = 9. Since angle H is 56 degrees, angle K must also be 56 degrees. The length of side HK can be determined using the Law of Cosines:
HK2 = GA2 + GK2 - 2(GA)(GK)cos(H) When we substitute the values we are familiar with, we obtain:
After solving the equation we obtain: HK2 = 462 + (3a + 19)2 - 2(46)(3a + 19)cos(56°).
HK2 = 2112 + 9a2 + 342a - 2764cos(56°) HK2 = 2112 + 9(9)2 + 342(9) - 2764cos(56°) HK2 732.4 By taking the square root of both sides, we obtain the following results:
∵ GA = 46, we can use the parallelogram's opposite sides being congruent to determine the length of side GK: HK 27.0
Then, we can use the Law of Cosines to determine the angle G's measurement:
cos(G) = (HK2 + GA2 - GK2) / (2(HK)(GA)) Using the values we are familiar with, we get,
cos(G) = (27.02 + 462 - 462) / (2(27.0)(46)) cos(G) 0.465 Using the inverse cosine, we get the following:
G ≈ 63.5°
Hence, the worth of every variable in the parallelogram is:
a = 9 HK = 27.0 GK = 46 G = 63.5°

Juan sold a bicycle at a discount of 15%. If the selling price was $340, find the usual price of the bicycle.
Answer: $400
Step-by-step explanation:
Discount = 15%
The original price/value of an item is always 100%
So selling price (%) = original price - discount = 100%-15% = 85%
We got selling price as 85%
This implies that 85% = 340
Let's find 1% first, then 100%
1% = 340÷85 = 4
100% = 4 × 100 = $400
The usual (normal/original) price is $400
Juan sold a bicycle at a discount of 15% if the selling price was $340 then the usual price of the bicycle was $400.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Let's represent the usual price of the bicycle by P.
Since Juan sold the bicycle at a discount of 15%, the selling price (S) would be 85% of the usual price (P).
We can express this relationship as an equation:
S = 0.85P
We also know that the selling price of the bicycle was $340.
Substituting S = $340 into the equation above, we get:
$340 = 0.85P
To find P, we can solve for it:
P = $340 / 0.85
P = $400
Therefore, the usual price of the bicycle was $400.

How do you find the area of the shaded region? Many geometry students struggle to solve shaded areas. The best way to find a shaded region's area is to familiarize yourself with the area decomposition method. The area decomposition method separates the basic shapes found in a given complex figure for fast and organized analysis. Two cases are present in obtaining the areas of the shaded regions – figures with holes and composite figures.
The area of the shaded region can be found by Area Decomposition Method.
Outer Area Minus Inner Area: Area of the shaded region = Area of the outer shape - Area of the unshaded inner shape
Area of Composite Figures: Area of the shaded region = Area of Region 1 + Area of Region 2 + ...... + Area of nth Region
The Area Decomposition Method:
Understanding the area decomposition method is the key to determining the area of a darkened zone.
For quick and efficient analysis, the area decomposition approach divides the fundamental forms present in a given complex figure.
To obtain the areas of the shaded zones, there are two scenarios.
They are of:
(1) Figures with holes and
(2) Composite figures.
Outer Area Minus Inner Area:
In figures with holes, take into account the area of the figure as a whole without the hole or hollow. By deducting the punch hole area from the whole figure, the remaining area can be found.
The area of the shaded region is equal to the Area of the outer shape minus the Area of the unshaded inner shape
Area of Composite Figures:
A composite plane figure's overall area is the same as the sum of its component areas.
The area of the shaded region is equal to the sum of the Area of Region 1, Area of Region 2, ......, Area of nth Region.

Find the coordinates of the midpoint of a segment with the endpoints (−8,−11) and (2,5)
The midpoint M of the given line segment with end points (−8,−11) and (2,5) is (-3,-3).
What is meant by the midpoint of a line segment?
A line segment in geometry is a section of a straight line that is enclosed by two clearly defined endpoints and contains all of the points on the line that lies inside those endpoints. The difference between a line and a line segment is that a line has no endpoints and can go on forever in either direction. The centre of a line segment is known as the midpoint. It is the centroid of the segment and of the endpoints, and it is equally distant from both of them. It cuts the section in half.
Given a line segment with endpoints A and B.
A = (−8,−11) = (x₁ , y₁)
B = (2,5) = (x₂, y₂)
W asked to find the midpoint. Let the midpoint be M.
M = ( (x₁ + x₂) /2 , (y₁ + y₂) / 2)
(x₁ + x₂) /2 = (-8 + 2) /2 = - 6/2 = -3
(y₁ + y₂) / 2 = (-11 + 5) /2 = -6/2 = -3
Therefore the midpoint M of the given line segment with end points (−8,−11) and (2,5) is (-3,-3).
