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).

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.

How do you determine the coordinates of a point after a reflection in the y-axis?
The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same.
A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.
When a point is reflected across the Y-axis, the Y-coordinates remain the same, and the X-coordinates are transformed into their opposite signs.
Therefore, the reflection of the point (x, y) across the Y-axis is (-x, y).
A reflection of a point, a line, in the Y axis reflects the image over the Y axis to create a mirror image. In this way, the Y axis would be called the axis of reflection.

Answer:
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.\

What are the solutions of 6t − 1 ≥ 4t + 13?
Answer:
t ≥ 7
Step-by-step explanation:
6t - 1 ≥ 4t + 13 ( subtract 4t from both sides )
2t - 1 ≥ 13 ( add 1 to both sides )
2t ≥ 14 ( divide both sides by 2 )
t ≥ 7
Answer:
Inequality Form: t ≥ 7
Interval Notation: [ 7, ∞ }
Step-by-step explanation:
1) Move all terms that contain "t" to the left side of the inequality by subtracting 4t from both sides.
a) 6t – 1 – 4t ≥ 13, THEN subtract 4t from 6t
b) 2t – 1 ≥ 13
2) Move terms that do not contain "t" to the right side of the inequality:
a) ADD 1 to both sides ––> 2t ≥ 13 + 1
b) ADD 13 and 1 ––> 2t ≥ 14
3) Divide each term by 2, then simplify:
= 2t/2 ≥ 14/2
4) Simplify the left side:
t = 14/2
5) Simplify the right side:
t ≥ 7

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.

With the help of the given equation, we know that the required slope is (A) 3/8.
What is a slope?In math, the gradient of a line is a number that tells you how steep it is and in which direction it goes in.
The point-slope form is a way of writing equations (y-y₁=m(x-x₁)) to emphasize the slope and a point on the line that isn't the y-intercept.
To highlight the same line's slope and y-intercept, you can rewrite the equation in slope-intercept form (y=mx+b).
So, we have the equation:
-3x + 8y = 12
Calculate the slope as follows:
We need to change it into a more general format.
-3x+8y=12
⇒ 8y = 3x+12
⇒ y = 3x/8+12/8
⇒ y = 3x/8+3/2
If you look at it in terms of y = mx+c, the m would be 3/8.

Your answer Daryl finds a pair of pants for $17.00. If the pants are on sale for 35% off, what is the sale price of the pants?
Answer:

Step-by-step explanation:
First, you make the percent into a decimal
35% - 0.35
Next, you multiply 17 and 0.35
17* 0.35= 5.95
Then, you subtract the discount which is $5.95 from $17
17-5.95= 11.05
So, the answer is $11.05
Hope this helps :)
Answer: $11.05
Step-by-step explanation:
First how much 35% of 17:
35% = 0.35
0.35 x 17 = 5.95
Next, subtract this discount off of the total:
17 - 5.95 = 11.05

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
