Question:
Given: Angle 2 is 65 degrees. Please note that L || M.
(a) What is the angle measurement of Angle 4? Explain the angle relationship used and show your work.
(b) What is the angle measurement of Angle 7? Explain the angle relationship used and show your work.
(c) What is the angle measurement of Angle 3? Explain the angle relationship used and show your work.
THERE ARE 3 PARTS TO THIS QUESTIONS; A, B, and C PLEASE ANSWER ALL!
Answer:
(a) ∠4 = 115°
(b) ∠7 = 65°
(c) ∠3 = 65°
Step-by-step explanation:
There are several applicable relationships in this figure. Perhaps the simplest is to take advantage of the relationships wherever any lines cross:
vertical angles are congruentangles forming a linear pair are supplementaryWhen two parallel lines are crossed by a transversal, the Corresponding Angle Theorem comes into play. It tells you ...
corresponding angles are congruent.The rule for vertical angles gives you ...
∠1 ≅ ∠4∠2 ≅ ∠3∠5 ≅ ∠8∠6 ≅ ∠7The rule for corresponding angles tells you ...
∠2 ≅ ∠6Angles 2 and 4 are a linear pair, so are supplementary.
There are many other relationships that can be derived from these, but these are sufficient to provide a basis for answering the questions.
__
(a)Angle 4 is supplementary to angle 2 so measures ...
∠4 = 180° -65° = 115°
__
(b)Angle 7 is a vertical angle to angle 6, which is a corresponding angle with angle 2. Vertical and corresponding angles are congruent, so ...
∠7 ≅ ∠6 ≅ ∠2 = 65°
(See also the comment below.)
__
(c)Angle 3 is a vertical angle to angle 2, so is congruent to it.
∠3 ≅ ∠2 = 65°
(Angle 3 is also "corresponding" to angle 7, which we just showed was 65°.)
_____
Additional comment
When the transversal crosses parallel lines at other than 90°, all obtuse angles are congruent, and all acute angles are congruent. The obtuse and acute angles are supplementary. Once you know one acute angle is 65°, you know all acute angles are 65°, and all obtuse angles are 115°.
Various theorems relate different angles pairs. For example, angles 2 and 7 are called "alternate exterior angles" (as are angles 1 and 8). There is a theorem that says alternate exterior angles are congruent. We arrived at the same fact using the congruence of corresponding and vertical angles.
use a known maclaurin series to obtain a maclaurin series for the given function. f(x) = xe8x f(x) = [infinity] n = 0 Find the associated radius of convergence, R.
The associated radius of convergence, R is infinity, or R = ∞.
To obtain the Maclaurin series for f(x) = xe^8x, we can use the known Maclaurin series for e^x, which is:
e^x = 1 + x + x^2/2! + x^3/3! + ...
Substituting 8x for x, we get:
e^(8x) = 1 + 8x + (8x)^2/2! + (8x)^3/3! + ...
Multiplying both sides by x, we get:
xe^(8x) = x + 8x^2 + (8x)^3/2! + (8x)^4/3! + ...
Therefore, the Maclaurin series for f(x) = xe^8x is:
f(x) = x + 8x^2 + (8x)^3/2! + (8x)^4/3! + ...
To find the radius of convergence, we can use the ratio test:
lim_n→∞ |(8x)^(n+1)/(n+1)!| / |(8x)^n/n!| = 8|x|/(n+1)
This limit approaches zero for all values of x, so the series converges for all x. Therefore, the radius of convergence is infinity, or R = ∞.

Solve for the value of k. (k+8) 400
Answer: The answer to this math question about solving for the value of k with the given full of the angles is k = 6.
Step-by-step explanation: As always to remember, all of the forming angles to a straight line with a sum of 180 degrees, so anyways, here are 6 steps in order to solve for the value of k:
Step 1. First, let's find the measures of the value of all 3 angles, the measures of all 3 angles are, 8°, 90°, and 40° that looks in the equation form like this: \(7k + 8 + 90 + 40 = 180.\)
Step 2. Next, after finding the measures of the value of all 3 angles, it's time to add all 3 angles up together that looks in the equation form like this: \(7k + 138 = 180.\)
Step 3. Then, let's move positive 138 to the right side so you got negative 138, and keep the positive 180 the same when moving to the left side that looks in the equation form like this: \(7k = 180 - 138.\)
Step 4. In addition to that, after moving positive 138 to the right side so you got negative 138, and keep the positive 180 the same when moving to the left side, it's time to subtract 138 degrees and 180 degrees that looks in the equation form like this: \(7k = 42.\)
Step 5. Now last but not least is finally, after subtracting 138 degrees and 180 degrees, it's time to divide the both sides by 7 that looks in the equation form like this: \(\frac{7k}{7}=\frac{42}{7}.\)
Step 6. Hence the value of k is 6.
I hope that my full given answer with my full given step-by-step explanation is very helpful to your own math question about solving for the value of k with the given full of the angles, please mark me as Brainliest, take care, always be safe, and have a great rest of the day and a great weekend! :D

Show one way that five children share
two pizzas equally
if there is 2 pizza and 5 children then 1/5 (fraction) of a pizza, or two slices, must be given to each child.
Start with two pizzas of equal size. Cut each pizza into 5 equal slices, so you have a total of 10 slices. Give each child 2 slices of pizza. Each child receives 2 slices of pizza, which is:
2/10 = 1/5 of a pizza
Each child now has 1/5 of a pizza.
Since there are 5 children, the total amount of pizza shared is:
5 × (1/5) = 1 pizza
Therefore, each child has 1/5 of a pizza, or 0.2 of a pizza.
To get the total amount of pizza that was shared, we can add up the amount of pizza each child received:
5 × (2/10) = 1 pizza
So, each child receives 2 slices of pizza, which is 1/5 of a pizza, and the total amount of pizza shared is 2 pizzas, or 1 whole pizza per 2 children.

Answer:
Reflect over the y-axis, vertically stretch by a factor of 3, and then shift down 1 unit
Step-by-step explanation:
The general form of the straight line equation is, y = m·x + c
Where;
m = The slope
c = The y-intercept
The parent function is, f(x) = x
The slope of the parent function, m₁ = 1
The y-intercept of the parent function, c₁ = 0
The x-intercept of the parent function = 0
The equation of the given function g(x) is derived as follows;
Two points on the line g(x) are (-2, 5) and (1, -4)
The slope of g(x), m₂ = (-4 - 5)/(1 - (-2)) = -3
The equation of g(x) is therefore;
y - 5 = -3 × (x - (-2)) = -3·x - 6
∴ y = -3·x - 6 + 5 = -3·x - 1
y = -3·x - 1
The slope of the given function, m₂ = -3
The y-intercept of the given function, c₂ = -1
The x-intercept of the function = -1
We have that a reflection of (x, y) across the y-axis gives (-x, y)
Therefore, the function g(x) is a reflection of f(x) across the y-axis
The slope of g(x) = -3 × The slope of f(x), therefore, g(x) is obtained by a vertical stretch of of f(x) by a factor of 3
The y-intercept of g(x) is lower than the y-intercept of g(x) by -1, therefore, f(x) is shifted down vertically by 1 unit to obtain g(x)
Therefore, the sequence of transformation that can be used to obtain g(x) from the parent function f(x) are;
Reflect over the y-axis, vertically stretch by a factor of 3, and then shift down 1 unit

ronald lau, chief engineer at south dakota electronics, has to decide whether to build a new state-of-the-art processing facility. if the new facility works, the company could realize a profit of $200,000. if it fails, south dakota electronics could lose $190,000. at this time, lau estimates a 50% chance that the new process will fail. the other option is to build a pilot plant and then decide whether to build a complete facility. the pilot plant would cost $5,000 to build. lau estimates a 60% chance that the pilot plant will work. if the pilot plant works, there is a 75% probability that the complete plant, if it is built, will also work. if the pilot plant does not work, there is only a 30% chance that the complete project (if it is constructed) will work. lau faces a dilemma. by analyzing this problem, help lau to maximize his expected payoff. what is the best decision you recommend for lau and what is the expected payoff? write your answer in the space below
I recommend that Ronald Lau build the pilot plant first to maximize his expected payoff. The expected payoff for this decision is $55,000.
To help Ronald Lau maximize his expected payoff, we can use decision analysis to evaluate the potential outcomes and probabilities of each decision.
The first decision is whether to build the new facility directly or to build the pilot plant first and then decide whether to build the complete facility.
If the new facility is built directly, the expected payoff is $200,000 × 0.5 + (-$190,000) × 0.5 = $5,000.
If the pilot plant is built first, the expected payoff is:
$5,000 + $200,000 × 0.75 × 0.6 + (-$190,000) × 0.25 × 0.6 = $55,000
or
$5,000 + (-$190,000) × 0.75 × 0.4 + $200,000 × 0.25 × 0.4 = -$45,000
The best decision is to build the pilot plant first since this decision has a higher expected payoff of $55,000 compared to the expected payoff of $5,000 for building the new facility directly.

Let us make the line from the picture, pointing the given equations:
From the draw and the given equations, we note that:
\(54=RT=RS+ST=4y+3+3y+9\)Therefore, we can solve the equation for y as follows
\(\begin{gathered} 54=4y+3+3y+9 \\ \\ 54=7y+12 \end{gathered}\)Where in the last line, we add the similar terms, for example 3y+4y=7y. Let us continue the calculations
\(\begin{gathered} 54=7y+12 \\ \\ 54-12=7y \\ \\ 42=7y \end{gathered}\)where in the second line of the equation above, we pass the 12 from the right to the left with opposite sign. We discover y as follows
\(\begin{gathered} 42=7y \\ \\ \frac{42}{7}=y \\ \\ 6=y \end{gathered}\)That is, we have y=6.
Let us now calculate the value of RD an RT. We know from the question that
\(\begin{gathered} RS=4y+3 \\ \\ ST=3y+9 \end{gathered}\)as we discover that y=6, substituting this value in the equations above we find:

sketch the area represented by g(x). g(x) = x t2 dt 1
The area represented by g(x) is a triangular region with base 1 and height (7/3) x, where x is the variable along the horizontal axis. The resulting shape will be a right triangle with vertices at (0,0), (1,0), and (0, (7/3) x).
It seems like you are asking to sketch the area represented by the function g(x) given as the integral of x with respect to t from 1 to 2. However, there seems to be a typo in your question. I will assume that you meant g(x) = ∫[1 to x] t^2 dt. Please follow these steps to sketch the area represented by g(x):
1. Draw the function y = t^2 on the coordinate plane (x-axis: t, y-axis: t^2).
To sketch the area represented by g(x) = x t2 dt 1, we first need to evaluate the definite integral. Integrating x t2 with respect to t gives us (1/3) x t3 + C, where C is the constant of integration. Evaluating this expression from t=1 to t=2 gives us (1/3) x (2^3 - 1^3) = (7/3) x.
2. Choose an arbitrary x-value between 1 and 2 (e.g., x = 1.5).
3. Draw a vertical line from the x-axis to the curve of y = t^2 at x = 1.5. This line represents the upper limit of the integral.
4. Draw another horizontal axis from the x-axis to the curve of y = t^2 at x = 1. This line represents the lower limit of the integral.
5. The area enclosed by the curve y = t^2, the x-axis, and the vertical lines at x = 1 and x = 1.5 represents the area for the given value of x.
In conclusion, the area represented by g(x) = ∫[1 to x] t^2 dt can be sketched by plotting the curve y = t^2, choosing a specific x-value between 1 and 2, and then finding the enclosed area between the curve, x-axis, and the vertical lines at x = 1 and x = chosen x-value.

The intermediate tangent of a
reverse curve is 600 m. long. The tangent of the reverse curve has
a distance of 300 m, which is parallel to each other. Determine the
central angle of the reverse curve if it has a common radius of 1000 m.
The central angle of the reverse curve is 0.6 radians.
The central angle of a reverse curve can be determined by using the length of the intermediate tangent and the radius of the curve. In this case, the intermediate tangent is given as 600 m and the common radius is 1000 m.
To find the central angle, we can use the formula:
Central angle = (Intermediate tangent length) / (Radius)
Plugging in the given values, we get:
Central angle = 600 m / 1000 m
Simplifying the expression, we find that the central angle is 0.6 radians.
Therefore, the central angle of the reverse curve is 0.6 radians.

You have round tables each seating 6 people. As your guests sit at the table, how many degrees must you rotate to look from the guest to their left to the guest to their right? (Hint: The interior angles of regular polygon measure ((n - 2) x 180) / n where n is the number of sides.)
To look from the guest to their left to the guest to their right at a round table seating 6 people, you need to rotate by 60 degrees.
For a regular polygon with n sides, the sum of its interior angles is given by ((n - 2) × 180) degrees. In the case of a round table seating 6 people, the table can be considered as a hexagon, which has 6 sides. Using the formula, we can calculate the sum of the interior angles:
((6 - 2) × 180) / 6 = (4 × 180) / 6 = 720 / 6 = 120 degrees
Since the table forms a complete circle, the sum of the interior angles is divided equally among the guests. Therefore, each guest sits at an angle of 120 degrees. To look from the guest to their left to the guest to their right, you need to rotate by the angle between adjacent guests, which is half of the angle they sit at:
120 / 2 = 60 degrees
Thus, to look from the guest to their left to the guest to their right at a round table seating 6 people, you need to rotate by 60 degrees.
