The coordinates of the orthocenter of the triangle J(3,-2) K(5,6) L(9,-2) are (5, -2).

Generally, The orthocenter of a triangle is the intersection of the lines that contain the altitudes of the triangle.

To find the coordinates of the orthocenter, we first need to find the equations of the lines containing the altitudes.

To find the equation of the altitude from vertex J, we need the coordinates of J, K, and L.

Using the given coordinates, we have J(3,-2), K(5,6), and L(9,-2).

The equation of the line containing the altitude from J is:

-2 = (-2-6)/(3-5) (x-5) + 6

The equation of the line containing the altitude from K is:

6 = (-2-6)/(5-9) (x-9) - 2

The equation of the line containing the altitude from L is:

-2 = (6-(-2))/(5-3) (x-3) + 2

Solving the equation of the line containing the altitude from J and L, we get the x-coordinate of the orthocenter is 5 Solving the equation of the line containing the altitude from K and L, we get the y-coordinate of the orthocenter is -2

Step-by-step explanation:

First, calm down.

The area of the trapezoid cannot be found in a straightforward way.

Instead, what we need to do here is divide the trapezoid into two parts, a right triangle and a trapezoid.

Finding the area of the right triangle is easy. You just need to multiply the sides and divide it by 2.

Area of right triangle = 5*4/2 = 10

Next, you need to find the area of the trapezoid.

Area of trapezoid(small) = (2+1)*4/2 = 6

All you need to do now is add the area of these two together, and you get 16.

Answer:

A = 16 units²

Step-by-step explanation:

the area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height between the parallel sides b₁ and b₋₂

here h = 4 , b₁ = 6 and b₂ = 2

A = [tex]\frac{1}{2}[/tex] × 4 × (6 + 2) = 2 × 8 = 16 units²

The profit in 1973 is 5.56 which is estimated by the given linear model.

The regression equation is used to predict or estimate the value of the response (or dependant) variables based on an understanding of the explanatory (or predictor) variables.

Let Y represent the profit (or loss) for a certain company X years after 1970. Based on the data shown, a statistician calculates a linear model

Y = -0.80X + 7.96 ....(i)

Using the above model to estimate the profit in 1973

Substitute the value of X = 3 in the equation (i),

Y = -0.80(3) + 7.96

Y = -2.4 + 7.96

Y = 5.56

C: person C receives exactly two aces in their five cards.

We need to calculate P(A∪B∪C). According to the principle of inclusion and exclusion:

P(A∪B∪C)= P(A)+P(B)+P(C)-P(A∩B)-P(A∩C)-P(B∩C)+P(A∩B∩C)

Total outcomes is equal to  because there 52 cards and we select 5 of them.

The probability of each event is given by:

P(A)=P(B)=P(C)===0.0399

where the possible outcomes are 2 aces and 3 of the other cards.

Then, the intersections of the events mean that one player gets 2 aces and the other gets 2 aces too.

P(A∩B)=P(B∩C)=P(A∩C)==0.0001

Finally,

P(A∩B∩C)=0 because it is not possible that the three events occur at the same time due to there are only 4 aces.

m = (nΣxy - ΣxΣy) / (nΣx^2 - (Σx)^2)

b = median y - m(median x)

Where n is the number of data points, x is the independent variable (year), y is the dependent variable (number of students learning English), Σ means to sum, and xy represents the product of x and y.

For this dataset, we have 5 data points, so n = 5.

x = 2003, 2004, 2005, 2006, 2007

y = 1.600, 1.599, 1.592, 1.570, 1.560

Σx = 10,015

Σy = 7,966

Σxy = 31,948

Σx^2 = 40,307

m = (531948 - 100157966)/(5*40307 - 10015^2) = -0.007

median x = 2005

median y = 1592

b = 1592 - -0.007 * 2005 = 1597.014

Divide the distance traveled by the amount of gas used. For example, driving 100 miles with a full tank and 5 gallons of gas is 10mpg. When it comes to fuel economy, it's important to know how much your car is costing you each time we drive it.

According to the Question:

The gas mileage is the number of miles that can be covered by a car for a particular amount of fuel.

We are given that the gas mileage of the car is 30 miles per gallon, that means that the car consumes 1 gallon of fuel for each 30 miles covered.

The amount of fuel needed to cover the following distance is:

a) For 90 miles, let x represent the number of gallon of fuel. Hence:

Distance covered / amount of fuel = 30 miles per gallon

  90/x = 30

⇒ x = 90/30

⇒ x = 3 gallons

b) For 246 miles, let x represent the number of gallon of fuel. Hence:

Distance covered / amount of fuel = 30 miles per gallon

⇒ 246/x = 30

⇒ x = 246/30

The absolute value inequality for the hearing range of each animal is mod(e - 6008) ≤ 5992 and mod(m - 46000) ≤ 45000, respectively.

An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative. You can write an absolute value inequality as a compound inequality. This holds true for all absolute value inequalities. You can replace > above with ≥ and < with ≤.

To solve absolute-value inequalities, first, we must drop the absolute-value bars and restate the inequality in one of two ways, depending on the case.

According to the question,

The elephant can hear: 16 ≤ e ≤ 12000

The avg hearing = (12000 + 16)/2 = 6008

Tolerance = 12000 - 6008 = 5992

Therefore, the value absolute value inequality for the hearing of the elephant is mod(e - 6008) ≤ 5992.

Similarly,

The mouse can hear: 1000 ≤ e ≤ 91000

The avg hearing = (12000 + 91000)/2 = 46000

Tolerance = 46000 - 1000 = 45000

Hence, the value absolute value inequality for the hearing of the mouse is mod(m - 46000) ≤ 45000.
