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.

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

Lindsay's z - score, given the mean score, the standard deviation, and her score, is 2. 35.

To calculate a z-score, you subtract the mean from the individual score and then divide by the standard deviation.

The formula is:

z = (x - μ) / σ

Where

x is the individual score

μ is the mean

σ is the standard deviation.

So, to find Lindsay's z-score:

z = (98 - 78.2) / 8.4

z = 19.8 / 8.4

z = 2.35

The graph that shows the function f(x) = -ln (x - 1) is graph C.

Option C is the correct answer.

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

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).

With the help of the given equation, we know that the required slope is (A) 3/8.

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.

Therefore, with the help of the given equation, we know that the required slope is (A) 3/8.

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.

The area of sector in question 9 is 141.87 ft² and the area of sector in question 10 is 107.70 m².

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

What is a sector of a circle?

The term "Minor Sector" refers to the tiny area of a circle that is removed by two circle radii. The minor sector is a tiny area occupied by two radii.

Here,

We have to find the formula of the minor sector and minor segment.

We concluded that

The formula of the minor sector =  (θ/360°) × π r²

The formula of the minor segment = (θ / 360°) × πr² - (1/2) r² sin θ (OR) r² [πθ/360° - sinθ / 2] if 'θ' is in degrees.
