Which graph shows the function f(x)=−ln(x−1)
The graph that shows the function f(x) = -ln (x - 1) is graph C.
Option C is the correct answer.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
f(x) = -ln (x - 1)
When x = 1, f(1) = - ln 0 = ∞
When x = 2, f(2) = - ln (2 -1) = -ln 1 = 0
When x = 3, f(3) = - ln (3 - 1) = - ln 2 = - 0.30
These coordinates are seen in graph C.
The graph in option C represents f(x).
Thus,
The graph in option C represents f(x).

Number of miles driven in a week.
Person. Miles
Vani 30
Ryan 18
Fatoumata 42
For every ___ miles Vani drove, Ryan drove __ miles.
The number of miles driven by Taub in a week is 3 times the number of miles driven by Valeria in a week.
How to express ratio in simplest form?The United States Department of Transportation Federal Highway Administration said that the average driver traveled 12,724 miles in 2020. That's down from 14,263 average annual miles in 2019. The 2020 average equates to 1,060 miles per month per driver, or about 35 miles per day.Although it's possible, you cannot drive 1000 miles in a day safely with a single driver. This would involve approximately 16 hours of driving before accounting for traffic and rest stops. Assuming a total travel time of 20 hours, you would need to depart in the early hours and share the driving.Often, 100,000 miles is considered a cut-off point for used cars because older vehicles often start requiring more expensive and frequent maintenance when mileage exceeds 100,000.The average American spends 18 days driving per year, with an average of eight hours and 22 minutes per week, a OnePoll study conducted on behalf of Cooper Tire found.Number of miles driven by each person in a week:
Valeria = 7
Taub = 21
Ruby = 35
Number of miles driven by Taub : Number of miles driven by Valeria
= 21 : 7
= 21/7
= 3/1
= 3 : 1
Therefore, the number of miles driven by Taub : number of miles driven by Valeria in a week is 3 : 1 in it's simplest form.

In LMN MN=15cm, LP is perpendicular to MN, LP=100 angle PLN=PNL. Calculate the length of LN
The length of LN is approximately 101.12 cm.
What is the length of the hypotenuse?
In a right triangle, the hypotenuse is the side opposite to the right angle and it is the longest side of the triangle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.
In a right triangle, the length of the hypotenuse is given by the Pythagorean theorem: c^2 = a^2 + b^2.
In this case, we are given that LN is the hypotenuse, and LP and MN are the other two sides.
We are also given that LP = 100 and MN = 15, and that angle PLN = PNL which means that the triangle is a right triangle.
We can use the Pythagorean theorem to find the length of LN:
LN^2 = LP^2 + MN^2
LN^2 = 100^2 + 15^2
LN^2 = 10000 + 225
LN^2 = 10225
LN = √10225
LN ≈ 101.12 cm
So the length of LN is approximately 101.12 cm.

A jeweler had a fixed amount of gold to make bracelets and necklaces. The amount of gold in each bracelet is 7 grams and the amount of gold in each necklace is 18 grams. The jeweler made a total of 7 bracelets and necklaces using 82 grams of gold. Determine the number of bracelets made and the number of necklaces made.
The number of bracelets made is 4 and number of necklaces made is 3.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Let x be the number of bracelets made and y be the number of bracelets made.
There are total of 7 bracelets and necklaces.
x + y = 7
Amount of gold in each bracelet = 7 grams
Amount of gold in x bracelets = 7x grams
Amount of gold in each necklace = 18 grams
Amount of gold in y necklaces = 18y grams
Total gold used is 82 grams.
7x + 18y = 82
We have two linear equations :
x + y = 7 ⇒ x = 7 - y
7x + 18y = 82
Substituting x = 7 - y in second equation,
7 (7 - y) + 18y = 82
49 - 7y + 18y = 82
11y = 82 - 49
11y = 33
y = 33/11
y = 3
x = 7 - y = 7 - 3 = 4
Hence the number of bracelets and necklaces are 4 and 3 respectively.

Need help with 9 an 10
The area of sector in question 9 is 141.87 ft² and the area of sector in question 10 is 107.70 m².
What is the area of sector in circle?A circle is a collection of points that are all equally distance from the circle's centre. The radius is the usual distance a circle travels from its centre to its point. The circle's centre (o) and radius (r) serve as its definition (r).
A sector is referred to as a component of a circle made up of the circle's arc and its two radii. It is a section of the circle made up of the arc's circumference and the radii of the circle at its ends.
Given in question 9, r = HK = 25 ft
angle of sector = 26°
so the area of sector A₉ = (26°/360°)π*r²
⇒ A₉ = (26°/360°)* 22/7 * (25)²
⇒ A₉ = (26°/360°)* (22 * 625)/7
⇒ A₉ = 357,500/2520
⇒ A₉ = 141.87 ft²
Given in question 10, SR = 26 m
⇒ r = ST = SR/2
⇒ r = 26/2 = 13 m
angle of sector = 73°
so the area of sector A₁₀ = (73°/360°)π*r²
⇒ A₁₀ = (73°/360°)* 22/7 * (13)²
⇒ A₁₀ = (73°/360°)* (22 * 169)/7
⇒ A₁₀ = 271,414/2520
⇒ A₁₀ = 107.70 m²

Explain how you can compare the cost of two items that are different sizes.
Answer:
You could compare the ounces or weight, the price per unit, or overall quality.
Step-by-step explanation:
You could use the ounce/weight to check which weighs more, or has more in it. Then figure out which is more reasonable. You could use the price per unit, and the ounce/weight because the price per unit/ price per ounce could be more expensive, or less expensive and make more sense to buy. Or you could just use overall quality. You can have an item with more in it, but have lower quality contents, when you could have a smaller amount with better quality contents, which might cost a little more.\

How do you find the midpoint between any two points using only their coordinates?
To find the midpoint between any two points in a plane using only their coordinates, you can use the midpoint formula. The midpoint formula is:
(x,y) = ((x1 + x2) / 2, (y1 + y2) / 2)
Where (x1, y1) and (x2, y2) are the coordinates of the two points, and (x,y) are the coordinates of the midpoint.
For example, if we have two points (-2,8) and (4,10)
(x,y) = ((-2 + 4) / 2, (8 + 10) / 2)
(x,y) = (1,9)
The midpoint of the given points (-2,8) and (4,10) is (1,9).
It's worth noting that this formula can be adapted for three-dimensional points, where the midpoint formula would be
((x1 + x2)/2, (y1 + y2)/2, (z1 + z2)/2)

Step-by-step explanation:
Part A
We have the relationship
[tex]b = 6a - 10[/tex]
When [tex]a[/tex] is [tex]-2[/tex], the value of [tex]b[/tex] is
[tex]b = 6(-2) -10 = -12 -10 = -22[/tex]
The corresponding value of [tex]c[/tex] for [tex]a = - 2[/tex] is -[tex]21[/tex]
[tex]-21[/tex] is greater than [tex]-22[/tex] so answer is : [tex]b[/tex] is greater
Part B
When [tex]c[/tex] is [tex]6[/tex], we see that the value of [tex]a[/tex] from the table is [tex]1[/tex]
The corresponding value of b is:
[tex]b = 6(1) - 10 = 6 - 10 = -4[/tex]
Part C
When [tex]b = 26[/tex], plugging this into the equation[tex]b = 6a - 10[/tex] we get
[tex]26 = 6a - 10\\\\26 + 10 = 6a\\\\36 = 6a\\\\[/tex]

What is the difference between factor theorem and remainder theorem Class 9?
The remainder theorem states that the value of f(a) is equal to the remainder for any polynomial f(x) when divided by the binomial xa. The factor theorem states that (xa) is a factor of f(x) and vice versa if an is a zero of a polynomial f(x).
A special example of the polynomial remainder theorem is the Factor theorem. So, according to the factor theorem, a polynomial has a factor if and only if: If and only if f (M) = 0, the polynomial x-M is a factor of the polynomial f(x). According to the Remainder Theorem, the remainder will be if a polynomial (x) is divided by a linear binomial of the kind (x - a) (a).
