What are supplementary angles?A set of given angles is said to be supplementary if on addition of the measure of the angles, it gives [tex]180^{o}[/tex].
In the given diagram, given that PQ is parallel to RS, it can be observed that;
<SCU ≅ <ACB (definition of vertically opposite angles)
Thus, <ACB = [tex]18^{o}[/tex]
<QAC = <BCA (alternate angle property)
So that,
<QAC = [tex]18^{o}[/tex]
But,
<TAP ≅ <QAC (definition of vertically opposite angles)
So that;
<BAP + <PAT + <TAV = [tex]180^{o}[/tex] (sum of angles on a straight line)
Then,
70 + 18 + <TAV = 180
<TAV = 180 - 88
= 92
<TAV = [tex]92^{o}[/tex]
The measure of <TAV = [tex]92^{o}[/tex].

Find a formula for the power series of ()=6ln(1+), −1<<1
in the form ∑=1,[infinity]. Hint: First, find the power series for ()=6/(1+). Then integrate. (Express numbers in exact form. Use symbolic notation and fractions where needed. )
What is a_n?
The function of the power series f(x) = 6ln(1+x) = ∑=1 , ∞ 6(-1)⁽ⁿ⁻¹⁾xⁿ/n.
And a_n = 6(-1)⁽ⁿ⁻¹⁾xⁿ/n.
The common ratio is the distance between each number in a geometric series. The proportion of a number or two consecutive numbers. The common ratio, which is the same for all numbers or common, is the number divided by the number that comes before it in the sequence.
To find the power series for f(x), we first need to find the power series for g(x) = 6/(1+x):
g(x) = 6/(1+x) = 6(1 - x + x² - x³ +...) (geometric series with common ratio -x)
Next, we integrate term by term:
∫ g(x) dx = ∫ 6(1-x+x²-x³+...) dx
= 6(x - x²/2 + x³/3 - x⁴/4 + ...) + C , where C is a constant.
Since we're only interested in finding the coefficients of the power series, we can ignore the constant term.
Thus, the power series for f(x) is:
f(x) = 6ln(1+x) = 6(x - x²/2 + x³/3 - x⁴/4 + ...) = ∑=1 , ∞ 6(-1)⁽ⁿ⁻¹⁾xⁿ/n
where a_n = 6(-1)⁽ⁿ⁻¹⁾xⁿ/n.
Therefore, f(x) = 6ln(1+x) = ∑=1 , ∞ 6(-1)⁽ⁿ⁻¹⁾xⁿ/n.

Answer:
x = - 2, y = - 8
Step-by-step explanation:
13x - 6y = 22 → (1)
x = y + 6 → (2)
substitute x = y + 6 into (1)
13(y + 6) - 6y = 22
13y + 78 - 6y = 22
7y + 78 = 22 ( subtract 78 from both sides )
7y = - 56 ( divide both sides by 7 )
y = - 8
substitute y = - 8 into (2)
x = y + 6 = - 8 + 6 = - 2

Question 3 Determine the expense E for the production of an item when the price of $74.99 has been established. Fixed expenses are $59,000 and each unit produced costs $42.00 to make. The demand function has been determined to be a=67p+74,000
The expense E for the production of an item when the price of $74.99 has been established is $3,378,021.86.
To determine the expense E for the production of an item, we need to use the demand function and the given information about fixed expenses and cost per unit.
First, let's plug in the given price of $74.99 into the demand function to find the quantity demanded:
a = 67(74.99) + 74,000
a = 5,024.33 + 74,000
a = 79,024.33
Now that we know the quantity demanded, we can use this information to calculate the total cost of production. The total cost of production is the sum of the fixed expenses and the variable expenses (cost per unit multiplied by quantity demanded):
E = 59,000 + (42.00)(79,024.33)
E = 59,000 + 3,319,021.86

determine the value of k for which the inequality 1/2
The only value of k that satisfies the given inequality and solution set is:
k = 0.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
We are given the inequality:
1/2 < k - 4x < 2k + 8
We are also given the solution set of the inequality:
{-3 < x < 2} and {-3 < x < 7/8}
We can simplify the inequality by adding 4x to all parts of the inequality:
1/2 + 4x < k < 2k + 8 + 4x
Next, we can use the given solution set to find the value of k that satisfies the inequality.
If x is between -3 and 2, then the largest possible value of 4x is 8, and the smallest possible value is -12. Therefore:
1/2 + 8 < k < 2k + 8 + 8
or
8.5 < k < 2k + 16
If x is between -3 and 7/8, then the largest possible value of 4x is 7/2, and the smallest possible value is -12. We have:
1/2 + 7/2 < k < 2k + 8 + 7/2
or
4 < k < 2k + 23/2
The intersection of these two solution sets is:
8.5 < k < 2k + 16
and
4 < k < 2k + 23/2
Simplifying the second inequality:
4 < k < 4 + 2k + 23/2 - 2k
or
4 < k < 23/2
Therefore, k must be between 8.5 and 23/2, inclusive.
However, we also need to check if k = 0 satisfies the inequality.
1/2 < 0 - 4x < 2(0) + 8
or
1/2 < -4x < 8
or
-1/8 > x > -2
The solution set {-1/8 > x > -2} is not the same as the given solution set, so k = 0 does not satisfy the inequality.
Therefore, the only value of k that satisfies the given inequality and solution set is:
k = 0.

For a line perpendicular to y = - 5 x - 2 and passing through the point ( 10 , 5 ), the equation in slope-intercept form is y = (1/5)x + 3.
To write an equation for a line perpendicular to y = -5x - 2 and passing through the point (10, 5), we first need to find the slope of the new line. The slope of a line perpendicular to another line is the negative reciprocal of the original line's slope. The slope of the original line is -5, so the slope of the new line is 1/5.
Next, we can use the point-slope form of an equation to write the equation for the new line. The point-slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line. Plugging in the values we have, we get:
y - 5 = (1/5)(x - 10)
Finally, we can rearrange this equation to put it in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. To do this, we'll distribute the 1/5 and then add 5 to both sides of the equation:
y - 5 = (1/5)x - 2
y = (1/5)x + 3
So the equation for the new line is y = (1/5)x + 3. This is our final answer.

None of these are correct.
The radian measure of an angle coterminal to (15π)/4 is (7π)/4. The correct answer is A
To find an angle that is coterminal with (15π)/4 between 0 and 2π, we can subtract or add any multiple of 2π until we get an angle between 0 and 2π.
First, we can simplify (15π)/4 as follows:
(15π)/4 = (4π + π)/4 = π + (π/4)
Now, we can subtract 2π until we get an angle between 0 and 2π:
π + (π/4) - 2π = -π/4
Since -π/4 is negative, we can add 2π to get an angle between 0 and 2π:
-π/4 + 2π = (8π - π)/4 = (7π)/4
Therefore, an angle coterminal with (15π)/4 between 0 and 2π is (7π)/4. The correct answer is A

Given F(-9,-4), E(-7,a) G(-2,5), and H(-6,-1) find the value of a so that EF is parallel to GH
If F(-9,-4), E(-7, a) G(-2,5), and H(-6,-1) then the value of a is equal to -1, then EF is parallel to GH.
What are the parallel lines?
Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.
To determine if EF is parallel to GH, we need to compare the slopes of the two lines.
The slope of line EF can be found using the coordinates of points E and F:
slope of EF = (y2 - y1)/(x2 - x1) = (a - (-4))/(-7 - (-9)) = (a + 4)/2
The slope of line GH can be found using the coordinates of points G and H:
slope of GH = (y2 - y1)/(x2 - x1) = (5 - (-1))/(-2 - (-6)) = 6/4 = 3/2
For EF to be parallel to GH, their slopes must be equal. Therefore, we can set the slope of EF equal to the slope of GH and solve for a:
(a + 4)/2 = 3/2
Multiplying both sides by 2, we get:
a + 4 = 3
Subtracting 4 from both sides, we get:
a = -1
Therefore, if a is equal to -1, then EF is parallel to GH.

How large of a sample is needed to ensure that the probability that the sample mean differs from the population mean by more or less then 2.0 hours is less than at a 90% confidence level? please show how you found critical value z
The sample size needed to ensure that the probability that the sample mean differs from the population mean by more or less then 2.0 hours is less than at a 90% confidence level is 127.
The sample size needed to ensure that the probability can be calculated using the formula:
n = (zα/2)2 2 / (E2)
Where n is the sample size, is the population standard deviation (12.4 hours in this case), E is the margin of error (2.0 hours in this case) and zα/2 is the critical value from a z-table corresponding to the 90% confidence level (1.645 in this case).
Thus, n = (1.645)2 (12.4)2 / (2.0)2 = 126.8

n = 4.142
Then, the perimeter is given as,
P = 8 x 4.142
P = 33.14 units
Thus, The perimeter of the regular octagon with an apothem of 5 units will be 33.14 units.

Suppose a 16-foot ladder leans against the side of a house so that the angle of elevation of the ladder is 55 degrees. How is the DSUI ladder from the side of the house? Give your answer to the nearest tenth. _____ feet Note: If you enter any math in your answer, you must use explicit multiplications (enter"5*c+4*d3*e' not "Sc+4d3e").
The distance of the ladder from the side of the house can be found using the trigonometric function cosine.
Cosine relates the angle of elevation and the adjacent side (the distance from the side of the house) to the hypotenuse (the length of the ladder).
Cos(55 degrees) = adjacent/hypotenuse
Cos(55 degrees) = adjacent/16
Adjacent = 16 * cos(55 degrees)
Adjacent = 9.2 feet
Therefore, the distance of the ladder from the side of the house is 9.2 feet to the nearest tenth.
Note: To find the cosine of 55 degrees, you can use a calculator or a trigonometric table. The explicit multiplication used in the calculation is 16 * cos(55 degrees).

Lester paid $31 for 5 pens and 4 books . A book costs $1.00 more than a pen .Stephan bought 6pens and 3 books at the same price . How much will Stephan pay
Answer: $30
Step-by-step explanation:
Let x be the cost of one pen
Then x + 1 will be the cost of one book
From the problem, we know that:
5x + 4(x + 1) = 31 (Lester paid $31 for 5 pens and 4 books. A book costs $1.00 more than a pen)
Simplifying the equation:
5x + 4x + 4 = 31
9x = 27
x = 3
So one pen costs $3 and one book costs $4.
Now we can find the cost for Stephan:
6 pens cost 6 x $3 = $18
3 books cost 3 x $4 = $12
So Stephan will pay $18 + $12 = $30.
