The coordinates of the orthocenter of the triangle are (-1. 1.2)

From the question, we have the following parameters that can be used in our computation:

L(-4,3), M(2,3), and N(-1,-2).

Calculate the slopes of LM and LN.

So, we have

m₁ = (3 - 3)/(2 + 4) = 0

m₂ = (-2 - 3)/(-1 + 4) = -5/3

The slopes of the lines perpendicular to the above slopes is

m₁ = -1/0 = undefined

m₂ = -1/(-5/3) = 0.6

Next, calculate the equation of lines passing through M in which the height perpendicular to LN lay

(y - yM) = m₁(x - xM)

y - 3 = 0.6(x - 2)

Next, calculate the equation of lines passing through undefined slope

x = -1

Substitute x = -1 in y - 3 = 0.6(x - 2)

y - 3 = 0.6(-1 - 2)

y = 3 + 0.6(-1 - 2)

y = 1.2

Hence, the coordinates is (-1. 1.2)

Answer:

N, M(2,3), L(-4,3), and (-1,-2).

Determine the LM and LN slopes.

The slopes of the lines perpendicular to the aforementioned slopes are m1 = -1/0 = undefined and m2 = -1/(-5/3) = 0.6. Hence, we obtain m1 = (3 - 3)/(2 + 4) = 0 and m2 = (-2 - 3)/(1 + 4) = -5/

Next, get the equation for lines passing through M with the height (y - yM) = m1(x - xM) y - 3 = 0.6. (x - 2)

The equation of lines running through an undefined slope, x = -1, must then be calculated.

Replace x = -1 with y - 3 = 0.6. (x - 2) y - 3 = 0.6(-1 - 2) y = 3 + 0.6(-1 - 2)\sy = 1.2

the coordinates are as a result (-1. 1.2)

Answer: The area of the triangle is given by the formula:

Area = (base * height) / 2

We are told that the area is less than 18 square inches, so we can write the inequality:

(base * height) / 2 < 18

Multiplying both sides by 2, we get:

base * height < 36

To find the possible values of "a", we need to isolate "base" on one side of the inequality. Let's assume that the base is equal to "a". Then we have:

a * height < 36

Dividing both sides by height, we get:

a < 36 / height

Since the height is 6 inches, we can substitute it in the inequality:

a < 36 / 6 = 6

So the possible values of "a" are any value less than 6 inches. That is,

0 < a < 6.

The cash price of the refrigerator would be $408.

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that a new refrigerator has a price of $480.00. The store will discount the price by 15%.

The new price of the refrigerator would be -

{x} = 480 - {15}% of 480

{x} = 480 - (15/100) x 480

{x} = 480 - 3/20 x 480

{x} = 480 - 3 x 24

{x} = 480 - 72

{x} = 408

Therefore, the cash price of the refrigerator would be $408.

As a result, the angle CBF has a 61 degree value.

When two consecutive lines or beams intersect at a single terminus, an angle is created. The apex of an arc is the location where two points come together.

Since Ray BF splits angle BCD into two equal portions because it is an angle bisector, the measures of angle CBF and angle DBF are the same. Consequently, we can write:

3z + 7 = 5z - 29

Simplifying and solving for z:

2z = 36

z = 18

Now we can substitute z = 18 into the expression for the measure of angle CBF:

3z + 7 = 3(18) + 7 = 61

The inequality equation is x ≥ 48 inches

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

The calculation is given as:

Remaining amount to fill = Total capacity - Current amount = 1 - 3/8 = 5/8

a. The values of Q1 = 355, Q2 = 510, Q3 = 910, range = 980 and IQR = 555.

b. The lower bound is not applicable and the upper bound is 1195. There are no outliers.

c.  The value at the 70th percentile is approximately 725.6 calories.

a. For the calories of each burger, we will find the Q1, Q2, and Q3, range, and IQR as follows -

Arranging the calorie values in order from smallest to largest we get,

250, 300, 410, 430, 445, 460, 510, 540, 670, 710, 840, 980, 1230.

The median of the lower half (from 250 to 540) is the average of the two middle values: (300 + 410) / 2 = 355.

Therefore, Q1 = 355.

Arranging the calorie values in order from smallest to largest we get,

250, 300, 410, 430, 445, 460, 510, 540, 670, 710, 840, 980, 1230.

The middle value is the median: Q2 = 510.

Arranging the calorie values in order from smallest to largest we get,

250, 300, 410, 430, 445, 460, 510, 540, 670, 710, 840, 980, 1230.

The median of the upper half (from 670 to 1230) is the average of the two middle values: (840 + 980) / 2 = 910.

Therefore, Q3 = 910.

Range = 1230 - 250 = 980.

IQR = Q3 - Q1 = 910 - 355 = 555.

b. To calculate the outlier boundaries, we need to first calculate the lower and upper limits as follows -

Lower bound: Q1 - 1.5 x IQR

Upper bound: Q3 + 1.5 x IQR

Lower bound: 430 - 1.5 x 310 = -25

Upper bound: 740 + 1.5 x 310 = 1195

Since there are no negative values for the calories of the burgers, the lower bound is not applicable. The upper bound is 1195, which is higher than the highest value in the dataset (1090). Therefore, there are no outliers.

c. To determine the value at the 70th percentile, we need to first order the calorie values from lowest to highest as follows -

250, 300, 410, 430, 445, 460, 510, 540, 670, 710, 740, 840, 980, 1090, 1230

Next, we will calculate the percentile rank of the 70th percentile -

Percentile rank = (70/100) x (n + 1) = 10.6

Since the percentile rank is not a whole number, we need to interpolate between the 10th and 11th values in the ordered list:

10th value: 710

11th value: 740

Using linear interpolation, we get:

Value at the 70th percentile = 710 + 0.6 x (740 - 710) = 725.6

Therefore, the value at the 70th percentile is approximately 725.6 calories.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

The relationship of the candlestick between height and time is represented by a straight line passing through the points (0, 8) and (3, 6).

Slope(m) = (6 - 8)/(3 - 0).

Slope(m) = - 2/3.
