In the figure given l || m , then find the value of X.
Answer:
42
Step-by-step explanation:
Line m and l are parallel so C and where that intersection is on the inside have the parallel lines, the angle there is an same side interior angle with C. Those add up to 180 degrees. So 180-82 is 98. Use vertical angle to find the angle in the triangle (not x yet; the other one). Vertical angles are congruent so that one is 98.
Now angles in a triangle add up to 180 degrees.
So we have 40+98=138.
The difference between 180 and 138 is 180-138=42 (that is x)
Answer:
42
Step-by-step explanation:
The solution is in the image below.
98+82 = 180
write an equation in slope intercept form for the line that passes through the points (3,2) and(-9,6)
Answer:
y = - [tex]\frac{1}{3}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (- 9, 6)
m = [tex]\frac{6-2}{-9-3}[/tex] = [tex]\frac{4}{-12}[/tex] = - [tex]\frac{1}{3}[/tex], hence
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 9, 6), then
6 = 3 + c ⇒ c = 6 - 3 = 3
y = - [tex]\frac{1}{3}[/tex] x + 3 ← in slope- intercept form

In which direction does the left side of the graph of this function point?
f(x) = 3x^3– x^2 + 4x - 2
Answer:
Down.
Step-by-step explanation:
ƒ(x) = 3x³ - x² + 4x - 2
"They" are asking you to determine the end behaviour of the function, that is, what happens to the function as x ⟶ -∞.
The important point to remember is that, when x is large enough, the term of highest degree (the x³ term) will be so large that you can ignore all the other terms.
If x is large and negative,
f(x) ≈ 3(-x)³ = 3(-1)³(x)³= -3x³
Thus, the graph is in the third quadrant and the graph points down.
The figure below shows the graph of your function. It points sharply down on the left-hand side.
What is the value of x
We know that the whole angle of the triangle is 73. Since the known angle is 45 degrees, we need to find out what the other is.
Subtract 45 from 73 to find the angle of the unknown triangle.
73-45=28.
Now that we know the value of the unknown triangle, solve for x
Make an equation.
2x+5=28
Subtract 5 on both sides.
2x=23
Divide 23 by 2 to isolate x.
X=11.5
The answer is C. 11.5

if y=5 when x=-3 find x when y=-1
Answer:
3/5
Step-by-step explanation:
5 / -1 = -5
so
-3 / -5 = 3/5
To find x when y=-1, substitute y=-1 into the equation y = -173.5 + 4.83x and solve for x.
Explanation:To find x when y=-1, you can use the equation of the line where y = 5 when x = -3. Based on the given information, the line of best fit is y = -173.5 + 4.83x. By substituting y = -1 into the equation, we can solve for x:
-1 = -173.5 + 4.83x
Adding 173.5 to both sides of the equation:
172.5 = 4.83x
Dividing both sides by 4.83:
x = 35.69
Therefore, when y = -1, x is approximately 35.69.

A regular octagon has an apothem measuring 10 in, and a
perimeter of 66.3 in
What is the area of the octagon, rounded to the nearest
square inch?
10 in
88 in 2
175 in 2
332 in2
700 in 2
Answer:
332 square inch
Step-by-step explanation:
Solving for an area of a regular octagon, we can make use of the formula shown below:
Area = 1/2 * apothem*perimeter
In this problem, the following values were given such as:
Apothem = 10 inches
Perimeter = 66.3 inches
Solving for the area:
Area = 1/2*10*66.3
Area = 331.5 inches²
The answer is 332.
Answer:
Option C. 332 in²
Step-by-step explanation:
In the figure attached, a regular octagon has been drawn with all equal sides and apothem OP = 10 in.
Perimeter of the given octagon is given as 66.3 in
We have to calculate the area of the octagon.
As we can see in the figure an octagon is a combination of 8 triangles.
So we will find the area of one triangle first.
Area of ΔBOC = [tex]\frac{1}{2}(BC)(OP)[/tex]
Since perimeter of octagon = 8 × one side = 8×BC
66.3 = 8× BC
BC = [tex]\frac{66.3}{8}[/tex]
BC = 8.288 in
Therefore, area of ΔBOC = [tex]\frac{1}{2}(10)(8.288)[/tex]
= 5×8.288
= 41.44 in²
Now area of octagon ABCDEFGH = 8×41.44 = 331.5 ≈ 332 in²
Therefore, area of the regular octagon will be 332 in²

They have different slopes and different y-intercepts, so they have no solution. They have different slopes and different y-intercepts, so they have one solution. They have the same slope and the same y-intercept, so they have no solution. They have the same slope and the same y-intercept, so they have infinitely many solutions.
Answer:
They have different slopes and different y-intercepts, so they have no solution
Step-by-step explanation:
Answer:
Infinite solutions Answer explained below
Step-by-step explanation:
Let us see the various conditions for intersections of two lines in simplest way.
1. Same slope and same y intercept : Infinite solutions
2. Same slope and different y intercepts : No solution
3. Different slope and same y intercept : unique solution
4. Different slope and different y intercept : Unique solution
Here slope means the tangent of the angle line makes with the positive x axis and y intercept is the y coordinate at which the line intersect the y axis.
In our equations , we our slopes and y intercepts as
y=-3x+6
slope = -3 and y intercept = 6
y=6-3x
slope = -3 and y intercept = 6
Hence same slope and same y intercept , thus have infinite solutions

If A=1/2h(x+y), what is y in terms of A, h, and x?
Answer:
see explanation
Step-by-step explanation:
Given
A = [tex]\frac{1}{2}[/tex] h(x + y)
Multiply both sides by 2 to eliminate the fraction
2A = h(x + y) ( divide both sides by h )
[tex]\frac{2A}{h}[/tex] = x + y ( subtract x from both sides )
y = [tex]\frac{2A}{h}[/tex] - x
The solution to the equation A=1/2h(x+y) for y in terms of A, h, and x, is y = 2A/h - x, obtained by algebraic rearrangement.
Explanation:To solve the given equation A=1/2h(x+y) for y in terms of A, h, and x, we first perform algebraic rearrangement. We want to get y in terms of A, h, and x. So, the first step is to eliminate the 1/2h from the right side of the equation. We can do this by multiplying both sides of the equation by 2/h, we get: 2A/h = x + y.
Now, to solve for y, we can simply subtract x from both sides: y = 2A/h - x. So now we have y expressed in terms of A, h, and x.

How many 3 digit multiples of both 4 and 6 are there?
To find the number of 3-digit multiples of both 4 and 6, we find the least common multiple (LCM) of 4 and 6, which is 12. Then, we count the number of 3-digit multiples of 12.
Explanation:To find the number of 3-digit multiples of both 4 and 6, we need to find the least common multiple (LCM) of 4 and 6. The LCM of 4 and 6 is 12. Since 12 is a multiple of both 4 and 6, any multiple of 12 will be a multiple of both 4 and 6.
Now, we need to find the number of 3-digit multiples of 12. The smallest 3-digit multiple of 12 is 108, and the largest is 996. So, we need to find how many numbers from 108 to 996 are divisible by 12.
We can divide 996 by 12 to find that the quotient is 83 and the remainder is 0. So, there are 83 3-digit multiples of 12. Therefore, there are 83 3-digit multiples of both 4 and 6.
Your school is organizing a carnival. You are building a ramp for a game the surface of the ramp will be 5 feet long with a total rise of 3 feet. Find the angle of elevation of the ramp
Answer:
Step-by-step explanation:
this angle is related to the ramp surface length (hypotenuse) and the rise in the ramp by the tangent function:
sin Ф = opp / hyp = 3 ft / 5 ft = 0.60
Use the inverse sine function to determine the angle Ф.
arcsin 0.60 = 36.9 degrees
Final answer:
The angle of elevation of the ramp is approximately 36.87 degrees, calculated using the tangent function in trigonometry and the given dimensions of the ramp's rise and length.
Explanation:
To find the angle of elevation of the ramp, we can use trigonometry, specifically the tangent function, which relates the angle of a right triangle to the ratio of the opposite side (rise) to the adjacent side (run). In this case, the ramp surface is the hypotenuse of the right triangle, the rise is the vertical change, and the run is the horizontal distance, which would be the horizontal projection of the ramp if it were flat. Since we know the rise is 3 feet and the ramp length (hypotenuse) is 5 feet, we can calculate the run using the Pythagorean theorem.
Calculate the run (horizontal distance): run = √(hypotenuse^2 - rise^2) = √(5^2 - 3^2) = √(25 - 9) = √16 = 4 feet.Now, calculate the angle of elevation using the definition of tangent: tangent(angle) = opposite/adjacent, which leads to angle = arctan(opposite/adjacent).Plug in the values for the rise and run: angle = arctan(3/4). Use a calculator to find the angle: angle ≈ 36.87°.The angle of elevation of the ramp is approximately 36.87 degrees.
On a coordinate plane, point A is located at (7,4), and point B is located at (-8,4). What is the distance between the two points?
Answer:
15
Step-by-step explanation:
This problem is quite simple; that is, if you know the proper formula that must be applied in finding the distance. The formula for finding the distance between two coordinate points is: √(x2-x1)^2+(y2-y1)^2. Now, obviously, (x2-x1)^2 and (y2-y1)^2 are both under the radical, where x2 and y2 represent the xy coordinates of point A (7,4) and x1 and y1 represent the xy coordinates of point B (-8,4). Now, all you must do is plug the points into the distance formula to get the answer, 15.
The distance between the two points is 15 units.
The coordinate points are A (7, 4) and B (-8,4).
What is the formula to find the distance between coordinate points?The formula to find the distance between two coordinate points is Distance=[tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2}-y_{1} )^{2}}[/tex].
Now, the distance between two coordinate points=[tex]\sqrt{(-8-7)^{2} +(4-4)^{2}}[/tex]
=√225
=15 units
