Explain why m angle 4 is equal to the sun of the measure of the two nonadjancent interior angels

Answers

Answer 1

Angle 4 is equal to the sum of the measures of the two nonadjacent interior angles because of the corresponding angles theorem for parallel lines and a transversal.

Angle 4 can be considered as the sum of two nonadjacent interior angles because of the properties of parallel lines and a transversal line. When a transversal line intersects two parallel lines, it creates several pairs of corresponding angles, alternate interior angles, alternate exterior angles, and consecutive interior angles.

In this case, we have two parallel lines and a transversal line that intersects them.

Angle 4 is formed by the intersection of the transversal line with one of the parallel lines.

The two nonadjacent interior angles that we are interested in can be identified as the adjacent angles on the other parallel line, corresponding to the same transversal line.

According to the corresponding angles theorem, when two parallel lines are cut by a transversal line, the corresponding angles formed are congruent.

Therefore, the two nonadjacent interior angles that correspond to angle 4 are congruent.

Since congruent angles have the same measure, we can conclude that the measure of angle 4 is equal to the sum of the measures of the two nonadjacent interior angles.

This property holds true for any pair of parallel lines intersected by a transversal line.

It is a fundamental concept in geometry that helps us understand the relationships between angles formed by parallel lines and transversals, and it is useful in solving various geometric problems and proofs.

Answers

Answer: D, C, 18

Step-by-step explanation:

The first one is trigonometry. It takes a long time to calculate, but sin20 degrees=0.342, and 15/43.8 is about 0.342

From that, we get the answer as D.

The second one is a bit of guesswork and logic

Notice that the angle on the left is 24

The angle on the right is 45

24 is about one-half of 45

51/3=17

So the triangle on the left has sides x, 24, and approx. 17.

17^2=289 and 24^2=576

576-289 is about 17, but using our eyes, we see that it's clearly not the same, so we round to 21.9 or C (risky, but don't know how to solve, sorry)

Last one:

Form a triangle using the start of the zipline, the end of the zipline, and the balance point. This forms a right triangle with angles 72, 90, and (2)

Three trains are made of identical train cars, so each car has the same number of seats. The first train has 418 seats, the second train has 456 seats, and the third train has 494 seats. How many cars are in each train if no train has more than 25 cars.

Answers

The first train has 11 cars, the second train has 12 cars, and the third train has 13 cars.

How to find the number of cars ?

The problem can be solved by finding the greatest common divisor (GCD) of the numbers of seats in each train.

Find the GCD of 418, 456, and 494. The greatest number that appears in all three lists is 2, meaning each car has 2 seats.

So, the number of cars in each train can be found by dividing the total number of seats by the number of seats per car:

First train:

= 418 seats / 38 seats per car

= 11 cars

Second train:

= 456 seats / 38 seats per car

= 12 cars

Third train:

The value of m ∠ABC=86° ,because of the cyclic quadrilaterals.

Hence, Option (B) is correct.

Since, We know that,

A cyclic quadrilateral is a four-sided polygon whose vertices all lie on a common circle.

The opposite angles of a cyclic quadrilateral have a total of 180°.

Hence, We can formulate;

m ∠ABC +  m ∠ADC  = 180°

m ∠ABC + 94° = 180°

m ∠ABC = 180° - 94°

m ∠ABC = 86°

Similarly, one can find m∠DCB

m∠DAB +  m∠DCB  = 180°

99° + m∠DCB = 180°

m∠DCB = 180° - 99°

m∠DCB = 81°

Your company is considering a new project that will require $100,000 of new equipment at the start of the project. The equipment will have a depreciable life of 10 years and will be depreciated to a book value of $5,000 using straight-line depreciation. The cost of capital is 14 percent, and the firm's tax rate is 21 percent. Estimate the present value of the tax benefits from depreciation. Multiple Choice

Answers

The present value of the tax benefits from depreciation is approximately $14,550.43.

How to solve for the present value

Under straight-line depreciation, the asset will depreciate evenly over its useful life. In this case, the depreciation expense for each year can be calculated as:

(Initial cost - Salvage value) / Useful life

= ($100,000 - $5,000) / 10

= $9,500 per year

This annual depreciation will provide a tax shield, as it reduces the firm's taxable income. The value of this tax shield each year is:

Depreciation expense * Tax rate

= $9,500 * 21%

= $1,995

This tax shield is received each year for the next 10 years. To calculate the present value of this stream of tax shields, we use the formula for the present value of an annuity:

PV = C * (1 - (1 + r)^-n) / r

where:

C = annual cash flow (our tax shield),

r = discount rate (the firm's cost of capital), and

n = number of periods (the depreciable life of the asset).

Substituting the values into the formula:

PV = $1,995 * (1 - (1 + 14%)^-10) / 14%

= $1,995 * (1 - 0.2706) / 14%

= $1,995 * 0.7294 / 14%

= $14,550.43

So the present value of the tax benefits from depreciation is approximately $14,550.43.

Answers

Part A: Measures of center
To find the measures of center, we need to determine the median for each school.

For Sky View School:
Arrange the data in order: 0, 0, 1, 2, 3, 4, 5, 5, 5, 6, 7, 7, 8, 9
The median is the middle value, which is 5.

For South Lake School:
Arrange the data in order: 0, 0, 1, 2, 2, 5, 6, 6, 8
The median is the middle value, which is also 5.

Therefore, the median class size for both schools is 5.

Part B: Measures of variability
To find the measures of variability, we need to determine the range and interquartile range (IQR) for each school.

For Sky View School:
The smallest value is 0 and the largest value is 9, so the range is 9 - 0 = 9.
To find the IQR, we need to find the first and third quartiles. The median is 5, so the first quartile is the median of the lower half, which is (0 + 1 + 2 + 3 + 4)/5 = 2. The third quartile is the median of the upper half, which is (6 + 7 + 8 +9)/4 = 7.25 (rounded to two decimal places).
Therefore, the IQR is 7.25 - 2 = 5.25.

For South Lake School:
The smallest value is 0 and the largest value is 8, so the range is 8 - 0 = 8.
To find the IQR, we need to find the first and third quartiles. The median is 5, so the first quartile is the median of the lower half, which is (0 + 0 + 1 + 2)/4 = 0.75 (rounded to two decimal places). The third quartile is the median of the upper half, which is (6 + 6 + 8)/3 = 6.67 (rounded to two decimal places).
Therefore, the IQR is 6.67 - 0.75 = 5.92 (rounded to two decimal places).

Part C: Choosing a school based on class size
If you are interested in a smaller class size, South Lake School is the better choice. This is because the range and IQR for South Lake School are smaller than those for Sky View School, indicating that the class sizes at South Lake School are more consistent and less variable. Additionally, the largest class size at South Lake School is 8, while the largest class size at Sky View School is 9, further indicating that South Lake School may have smaller class sizes overall.
Part A:
Measures of center for Sky View School:
Mean = (0+1+2+3+4+5+5+5+6+7+7+8+9)/13
Mean = 4.8
Median = 5

Measures of center for South Lake School:
Mean = (0+1+2+2+3+5+6+6+8+8)/10
Mean = 4.1
Median = 5

Part B:
Measures of variability for Sky View School:
Range = 9 - 0 = 9
Interquartile Range (IQR) = Q3 - Q1 = 7 - 2 = 5
Variance = [(0-4.8)^2 + (1-4.8)^2 + (2-4.8)^2 + (3-4.8)^2 + (4-4.8)^2 + (5-4.8)^2 + (5-4.8)^2 + (5-4.8)^2 + (6-4.8)^2 + (7-4.8)^2 + (7-4.8)^2 + (8-4.8)^2 + (9-4.8)^2]/12
Variance = 7.6
Standard Deviation = √7.6
Standard Deviation = 2.76

Measures of variability for South Lake School:
Range = 8 - 0 = 8
Interquartile Range (IQR) = Q3 - Q1 = 6 - 1 = 5
Variance = [(0-4.1)^2 + (1-4.1)^2 + (2-4.1)^2 + (2-4.1)^2 + (3-4.1)^2 + (5-4.1)^2 + (6-4.1)^2 + (6-4.1)^2 + (8-4.1)^2 + (8-4.1)^2]/9
Variance = 6.45
Standard Deviation = √6.45
Standard Deviation = 2.54

Part C:
If you are interested in a smaller class size, South Lake School is a better choice for you. This is because the measures of center and variability for South Lake School are both smaller than those for Sky View School.

Find the measure of the line segment indicated. Assume that lines are tangent.

Answers

The measure of the two line segments are 36 and 27.

We have,

The secant and tangent rule on a circle.

DC is the tangent and ABC is the secant.

Then,

DC² = (AB + BC) x BC

Now,

Substituting.

(4x + 11)² = (27 + 5x - 11) x (5x - 11)

To solve the given equation (4x + 11)² = (27 + 5x - 11) x (5x - 11) for x, we will expand both sides of the equation and then simplify:

Expanding the left side:

(4x + 11)² = (4x + 11)(4x + 11) = 16x² + 44x + 44x + 121 = 16x² + 88x + 121

Expanding the right side:

(27 + 5x - 11) x (5x - 11) = (16 + 5x)(5x - 11) = 80x² - 176x + 75x - 165 = 80x² - 101x - 165

Setting the left and right sides equal to each other:

16x² + 88x + 121 = 80x² - 101x - 165

Rearranging the equation:

0 = 80x² - 16x² - 101x - 88x - 165 - 121

0 = 64x² - 189x - 286

Now, we have a quadratic equation.

We can solve it by factoring, completing the square, or using the quadratic formula.

Let's use the quadratic formula to find the solutions for x:

x = (-b ± √(b² - 4ac)) / (2a)

In our case, a = 64, b = -189, and c = -286.

Substituting these values into the quadratic formula:

x = (-(-189) ± √((-189)² - 4(64)(-286))) / (2(64))

x = (189 ± √(35721 + 73216)) / 128

x = (189 ± √108937) / 128

Since the discriminant (b² - 4ac) is positive, we have two distinct real solutions. Evaluating the square root:

x = (189 ± 329) / 128

We have two possible solutions for x:

x₁ = (189 + 329) / 128 = 518 / 128 = 4.047 = 4

x₂ = (189 - 329) / 128 = -140 / 128 = -1.094 (rejected)

Now,

The line segments are:

AC = 27 + 5x - 11 = 27 + 5 x 4 - 11 = 27 + 20 - 11 = 36

CD = 4x + 11 = 4 x 4 + 11 = 16 + 11 = 27

Thus,

The measure of the two line segments are 36 and 27.

tanner has four times as many shirts as pants, and he can use them to make 100 different shirt and pants outfits. How many pants does Tanner have?

Show your work

Answers

Answer:

Let's assume Tanner has "x" pants.

Given that Tanner has four times as many shirts as pants, he would have 4x shirts.

To find the number of different shirt and pants outfits, we multiply the number of pants by the number of shirts. In this case, it would be x * 4x = 4x^2.

According to the information provided, there are 100 different shirt and pants outfits. So we can set up the equation:

4x^2 = 100

To solve for x, we divide both sides of the equation by 4:

x^2 = 25

Taking the square root of both sides, we get:

x = ±5

Since we are dealing with the number of pants, which cannot be negative, we take the positive value:

x = 5

Therefore, Tanner has 5 pants.

To determine how many weeks it took for Tom to have 15 cards collected, we need more information about the growth rate of his collection. The given information states that by week 5, Tom had collected 12 cards, but it doesn't provide details about the rate of card collection.

If we assume that Tom's card collection grows at a constant rate, we can calculate the rate of card collection per week using the given information. By week 5, Tom had collected 12 cards. This means that on average, he collected 12/5 = 2.4 cards per week up to that point.

Using this average rate, we can estimate how many weeks it would take for Tom to have 15 cards collected. We'll divide the total number of cards (15) by the average rate of card collection (2.4 cards per week):

15 cards / 2.4 cards per week ≈ 6.25 weeks.

Therefore, it would take approximately 6.25 weeks (or 6 weeks and 3 days) for Tom to have 15 cards collected, assuming a constant growth rate.

9. The Super Vision cable TV/Internet/phone provider advertises a flat $100 monthly fee for all
three services for a new customer. The rate is guaranteed for 5 years. Cable Zone normally
charges $46 for monthly home phone service, $36 for monthly Internet service, and $56 for
monthly cable television.
a. How much could a customer save during the first year by switching from Cable Zone to
Super Vision?
b. Super Vision raises the rates 23% after a new customer's first year, how much will a customer
who switched from Super Vision save in the second year?
c. If Super Vision raises the rates 18% for the third year compared to the second year, which
company is cheaper for the third year?

Answers

a. $456 would be the amount a customer could save during the first year by switching from Cable Zone to Super Vision.

b. Super Vision raises the rates 23% after a new customer's first year,  a customer who switched from Super Vision save $180 in the second year.

c. Super Vision raises the rates 18% for the third year compared to the second year, for the third year, Cable Zone would be cheaper.

a. To calculate how much a customer could save during the first year by switching from Cable Zone to Super Vision, we need to compare the costs of the two providers.

Cable Zone charges $46 for monthly home phone service, $36 for monthly Internet service, and $56 for monthly cable television. Therefore, the total cost per month with Cable Zone is:

$46 (home phone) + $36 (Internet) + $56 (cable television) = $138

Super Vision, on the other hand, offers all three services for a flat $100 monthly fee. So, the customer would save:

$138 (Cable Zone cost) - $100 (Super Vision cost) = $38 per month

Therefore, during the first year, the customer could save:

$38 (monthly savings) * 12 (number of months) = $456

b. After the first year, Super Vision raises the rates by 23%. The new monthly fee would be:

$100 (original fee) + 23% (rate increase) * $100 (original fee) = $123

To calculate the savings in the second year, we need to compare the new Super Vision fee to the cost with Cable Zone:

$138 (Cable Zone cost) - $123 (Super Vision cost) = $15 per month

Therefore, in the second year, the customer would save:

$15 (monthly savings) * 12 (number of months) = $180

c. If Super Vision raises the rates by 18% for the third year compared to the second year, we need to calculate the new monthly fee. The new Super Vision fee would be:

$123 (second-year fee) + 18% (rate increase) * $123 (second-year fee) = $145.14

To determine which company is cheaper for the third year, we compare the new Super Vision fee to the cost with Cable Zone:

$138 (Cable Zone cost) - $145.14 (Super Vision cost) = -$7.14

In this case, the Super Vision cost is higher than the Cable Zone cost by $7.14 per month. Therefore, for the third year, Cable Zone would be cheaper.

Overall, during the three-year period, the customer would save a total of $456 (first year) + $180 (second year) = $636 by switching to Super Vision.

Let f be a one-to-one function and let g be the inverse of f. Then (f°g)(x)=___ and (g°f)(x)=___

Answers

If f is a one-to-one function and g is the inverse of f, then (f°g)(x) = x and (g°f)(x) = x.

We have,

(f°g)(x) means applying the function f to the result of applying the function g to x.

Since g is the inverse of f, applying f to the result of applying g to x will give us back x.

(g°f)(x) means applying the function g to the result of applying the function f to x.

Since g is the inverse of f, applying g to the result of applying f to x will also give us back x.

In both cases, the compositions result in the original input value x.

Thus,

If f is a one-to-one function and g is the inverse of f, then (f°g)(x) = x and (g°f)(x) = x.

A ball is thrown from an initial height of 3 feet with an initial upward velocity of 34 ft/s. The ball's height h (in feet) after t seconds is given by the following.

h=3+34t-16t^2

Answers

What is the maximum height of the ball and when does it occur?

To find the maximum height of the ball, we need to find the vertex of the parabolic function h(t) = 3 + 34t - 16t^2, which represents the height of the ball as a function of time. The vertex has a t-coordinate of -b/2a, where a = -16 and b = 34.

t = -b/2a = -34/(2*(-16)) = 1.0625

To find the corresponding height, we substitute t = 1.0625 into the equation for h(t):

h(1.0625) = 3 + 34(1.0625) - 16(1.0625)^2 ≈ 43.015625

Therefore, the maximum height of the ball is approximately 43.015625 feet, and it occurs after 1.0625 seconds.

Sebastian purchases two pieces of equipment for $109,000. Appraisals of the equipment indicate that the fair market value of the first piece of equipment is $76,300 and that the second piece of equipment is $119,900. What is Sebastians basis in these two assets?

Answers

Sebastian's basis in the two assets are: $42,389 and $66,611

How to calculate the total assets?

The computation of the Sebastian's basis in these two assets is shown below:

= Market value of the first piece of equipment ÷ Total market value of two pieces of equipment × purchase value of two pieces of equipment

= ($76300 ÷ $(76300 + 119900)) × $109,000

= $42,389

= Market value of the second piece of equipment ÷ Total market value of two pieces of equipment × purchase value of two pieces of equipment

= ($119,900 ÷ $(76300 + 119900)) × $109,000

= $66,611

The Total market value of two pieces of equipment

= $(76300 + 119900)

= $196,200

Answer:

  3. see attached. Domain x > 1; Range all reals

  4. √15 ≈ 3.87298

Step-by-step explanation:

You want a graph and the domain and range of f(x) = 3log(2(x-1)) +4, and the value of (3x)^(x/10) when x satisfies 2^x -2^(x-1) = 16.

3. Log function

The function f(x) = 3log(2(x -1)) +4 represents horizontal and vertical scaling, as well as horizontal and vertical translation. The values in each case are different, so we can describe their effect by referencing their value.

1 — a horizontal right shift of the log function by 1 unit

2 — a horizontal compression of the log function by a factor of 2

3 — a vertical expansion of the log function by a factor of 3

4 — a vertical shift upward of the log function by 4 units.

Some points that you might graph for the parent log function would be (0.1, -1), (1, 0), (10, 1). The effect of these shifts is to transform them to ...

  (x, y) ⇒ (x/2 +1, 3y +4)

  (0.1, -1) ⇒ (1.05, 1)

  (1, 0) ⇒ (1.5, 4)

  (10, 1) ⇒ (6, 7)

The right shift 1 unit moves the domain to x > 1.

The range continues to be all real numbers.

4. (3x)^(x/10)

We can solve the given equation as follows:

   2^x -2^(x -1) = 16

   2^(x-1) · (2 -1) = 16

  2^(x -1) = 2^4

  x -1 = 4

  x = 5

Then the expression you want the value of is ...

  (3·5)^(5/10) = 15^(1/2) = √15 ≈ 3.87298
