Calculate the area of triangle WXY with altitude YZ, given W(2, −1), X(6, 3), Y(7, 0), and Z(5, 2). (6 points) 8 square units 9.4 square units 7.7 square units 12 square units
The area of triangle WXY with altitude YZ is: 8 square units.
Area of a TriangleArea = 1/2(base × height)
Altitude = height.
Given:
Base = WX = distance between W(2, −1) and X(6, 3):
Using distance formula, [tex]WX = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex]:
[tex]WX = \sqrt{(3 - (-1))^2 + (6 - 2)^2}\\\\\mathbf{WX = 5.7 $ units}[/tex]
Altitude/height = YZ = distance between Y(7, 0), and Z(5, 2):
[tex]YZ = \sqrt{(0 - 2)^2 + (7 - 5)^2}\\\\\mathbf{YZ = 2.8 $ units}[/tex]
Area of triangle WXY = 1/2(WX × YZ)
Area of triangle WXY = 1/2(5.7 × 2.8) = 7.98
Area = 8 square units.

Answer:
2
Step-by-step explanation:
Answer:
2x + 19.
Step-by-step explanation:
The reasoning behind this is that one must find the disparity between the first and second expressions - 9x+14 and 7x-5. To do this, one subtracts 7x-5 from 9x+14. Set this up as though it were a normal subtraction problem - 9x+14 over 7x-5 with the little subtraction symbol to the left. When subtracting the negative five from fourteen, one adds the five to the fourteen due to the fact that the five was already negative and as such the negatives cancel out. The 7x is simply subtracted from the 9x, resulting in 2x. This leads to 2x + 19.

Find the y-intercept of the line on the graph.
Enter the correct answer
Given:
The graph of a line.
To find:
The y-intercept of the line.
Solution:
y-intercept of a line is the point at which the line intersect the y-axis.
We have, graph of the line.
From the given graph it is clear that the line intersect the y-axis at (0,4).
So, y-intercept is at point (0,4).
y-intercept = 4
Therefore, the y-intercept is 4.
Elena paints the back of a aquarium it has a height of 1 3/4 feet the painted area is 5 5/6 what is the length
Answer:
3 1/3 feets
Step-by-step explanation:
Given that:
Height of aquarium = 1 3/4 feets
Area of aquarium = 5 5/6 ft²
The length of aquarium = x
Aquarium is shaped in the form of a rectangle :
Area of a rectangle = Length * width
5 5/6 = x * 1 3/4
35/6 = 7x/4
Cross multiply :
7x * 6 = 35 * 4
42x = 140
x = 140 / 42
x = 3 14/42
x = 3 1/3 feets
Hence, Length of the back of aquarium is 3 1/3 feets

In which branch of statistics would a researcher acquire twenty-five 2000 Toyota Celicas, drive them until they had a major mechanical failure, record the final mileage, and then write a report for Car and Driver?
Answer:
The answer is "descriptive statistics".
Step-by-step explanation:
Descriptive statistics are short descriptive factors that add up a production set, that can be either a reflection of a whole or a sample population. It is broken down into cumulative frequency measurements and variance measurements. The study uses descriptive statistics to explain the profile of the respondents. People give simple summaries about the sample as well as the actions.

Can an object accelerate if it's moving with constant speed?
Yup! Many people find this counter-intuitive at first because they forget that changes in the direction of motion of an object—even if the object is maintaining a constant speed—still count as acceleration.

A map has a scale of 1: 1250000. On a map, The cave of truth is 1.9cm away from the waterfall of dreams. How far away are they in real life?
Answer:
2,375,000
Step-by-step explanation:
From the question,
A map has a scale of 1: 1250000.
We are told that:
On a map, The cave of truth is 1.9cm away from the waterfall of dreams.
How far away are they in real life?
This is calculated as:
1 = 1250000
1.9 = x
Cross Multiply
x = 1.9 × 1250000
x = 2,375,000
Therefore, there distance in real life = 2,375,000

plug the numbers into a calculator
(9-3)=6
5^2=25
25*6=150
Step-by-step explanation: To handle these evaluation problems, you must be able to deal with positives and negatives, and you must know your order of operations. In addition, it's a good idea to get into the habit of using parenthses when substituting numbers in for variables.
Notice that we have a set of parenthses in our problem and remember that we use parenthses when substituting our numbers into the problem.
To avoid the confusion of having too many sets of parenthses,
let's change the parenthses in the original problem to brackets.
Now let's substitute using parenthses.
So we have (5)² · [(9) - (3)].
Since the parenthses were in the original problem were replaced
by brackets and parenthses come first in your order of operations,
in our problem the brackets are going to come first.
So first simplify 9 - 3 which is 6.
So we have (5)² [(6)].
Exponents come next so we square the 5 to get 25
and that gives us (25) [(6)] which is 150.
Find the value of x.
Answer:
The value of x is 120°
Step-by-step explanation:
We should draw a line parallel to the given parallel lines and passes through the vertex of the measure x and divides it into two angles of measures x1 and x2, look at the attached figure
In the given figure
∵ The dashed line is parallel to the given line up
∴ The angle of the measure 70° and the angle x1 are alternate angles
∵ The alternate angles are equal in measures
∴ x1 = 70°
∵ The dashed line is parallel to the given line down
∴ The angle of the measure 50° and the angle x2 are alternate angles
∵ The alternate angles are equal in measures
∴ x2 = 50°
∵ x = x1 + x2
∴ x = 70 + 50
∴ x = 120°
∴ The value of x is 120°
Answer:
x= 120
Step-by-step explanation:
Alternated angles are 50 and 70
