Answer:

d = 3h - 6

Step-by-step explanation:

h = d/3 + 2

Subtract 2 from both sides to isolate the term involving d:

h - 2 = d/3

Multiply both sides by 3 to eliminate the fraction:

3(h - 2) = d

Simplifying the right-hand side, we get:

d = 3h - 6

Therefore, the formula in terms of d is:

d = 3h - 6.

We can use the tangent function to solve this problem. Let h be the height of the skyscraper.

First, we need to find the length of the adjacent side of the right triangle formed by Sadie, the base of the skyscraper, and the point where she is standing. This length is the horizontal distance between Sadie and the base of the skyscraper, which is 275 meters.

Next, we can use the tangent of the angle of elevation to find the ratio of the opposite side (the height of the skyscraper) to the adjacent side:

tan(36°) = h/275

Solving for h, we get:

h = 275 tan(36°)

Using a calculator, we find:

h ≈ 198.64 meters

Therefore, the height of the skyscraper is approximately 198.64 meters.

Calculating the distance between locations C and D will provide us with the vector CD's magnitude, which we will then use to determine the vector CD's direction and magnitude. Thus, 5 miles in size, with a direction of roughly 53.13 degrees, is the CD.

The size and direction of a vector are two different sorts of information. A vector's length is measured by its magnitude, and its direction indicates its direction of travel. The most popular way to express vector direction is in degrees, though it can be expressed in other ways as well. Vector examples include acceleration and velocity. A vector's length is considered to be its magnitude.

The distance formula between the given two points (x1, y1) and (x2, y2) is:

d = √((x2 - x1)² + (y2 - y1)²)

Plugging in the values for points C and D, we get:

d = √((0 - (-4))² + (1 - 4)²)

= √(16 + 9)

Answer: y < 5x+6

Step-by-step explanation:

Answer:

y = 3x - 10

Step-by-step explanation:

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept (the value of y when x is zero).

See the attached worksheet.  Let's calculate slope, m.  Slope is defined as the Rise/Run, or change in y over the change in x.  Assuming that the data are points on a straight line, we can pick any two points to determine slope.  Let's use (25,65) and (28,74).  See the worksheet.  The slope,m, is shown to be 3.  Now we can write:

  y = 3x + b

To find b, the y-intercept, we can use the above expression and substitue any of the given points for x and y, leaving b as the only unknown.  Let's use point (25.65):

 y = 3x + b

65 = 3*(25) + b      [for point (25,65)]

 65 = 75 + b

  b = - 10

The equation is therefore y = 3x - 10

After addressing the issue at hand, we can state that As a result, the linear equation  statue towers over Regan by 12 metres.

In algebra, a linear equation refers to one with its form y=mx+b. B is the gradient, and m is the esta. The preceding clause is commonly referred to as a "linear function with two variables" so even though y and x are variables. Bivariate linear equations are linear equations with two variables. There are several linear equations: 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. When an equation seems to have the structure y=mx+b, where m is the slope and b is the y-intercept, it is said to be linear. When a measurement seems to have the formula y=mx+b, both with m identifying its slope and b denoting the y-intercept, it is said to be linear.

Let's call the statue's height "h". The distance between Regan and the statue is 12 metres, and the distance between the top of the statue and Regan's head is 20 metres. To visualise the situation, we can draw the following diagram:

  Regan

       |

       | 20 m

       |

       |

       o-----|-----o

      Statue  12 m

The height of the statue minus the distance from Regan to the statue equals the vertical distance from the top of the statue to Regan's head. So far, we have:

h - 12 = 20

When we solve for h, we get:

h = 32

As a result, the statue stands 32 metres tall. To determine how much taller the statue is than Regan, subtract Regan's height from the statue's height:

32 - 20 = 12

As a result, the statue towers over Regan by 12 metres.

Graham's law οf diffusiοn states that the rate οf diffusiοn οf a gas is inversely prοpοrtiοnal tο the square rοοt οf its mοlar mass. This means that lighter gases diffuse faster than heavier gases.

We can use Graham's law οf diffusiοn tο sοlve this prοblem, which states that the rate οf diffusiοn οf a gas is inversely prοpοrtiοnal tο the square rοοt οf its mοlar mass.

Let's assume that the mοlar mass οf hydrοgen and chlοrine are M1 and M2 respectively. Then, we can write:

Rate οf diffusiοn οf hydrοgen / Rate οf diffusiοn οf chlοrine = √(M2/M1)

We knοw that 200cm³ οf hydrοgen diffuse thrοugh the pοrοus pοt in 40s. Let's assume that the rate οf diffusiοn οf hydrοgen is R. Then, we can write:

R / Rate οf diffusiοn οf chlοrine = √(M2/M1)

R / Rate οf diffusiοn οf chlοrine = √(2/71) (mοlar masses οf hydrοgen and chlοrine are 2g/mοl and 71g/mοl respectively)

R / Rate οf diffusiοn οf chlοrine = 0.146

Rate οf diffusiοn οf chlοrine = R / 0.146

We want tο find the time it takes fοr 300cm³ οf chlοrine tο diffuse thrοugh the same pοt, sο we can write:

300 / Rate οf diffusiοn οf chlοrine = time

Substituting the value οf Rate οf diffusiοn οf chlοrine, we get:

300 / (R / 0.146) = time

Simplifying, we get:

time = 300 x 0.146 / R

We dοn't knοw the exact value οf R, but we knοw that it takes 40s fοr 200cm³ οf hydrοgen tο diffuse thrοugh the same pοt. Sο we can write:

R = 200 / 40 = 5 cm³/s

Substituting this value in the equatiοn fοr time, we get:

time = 300 x 0.146 / 5 = 8.76 s

Assuming Janie's parents have AGI of $177,600, the American Opportunity Tax Credit that Janie's parents can claim for her is $2,500.

The American Opportunity Tax Credit (AOTC) is a tax credit that allows taxpayers to reduce their federal income tax liability for qualified education expenses paid for an eligible student.

To calculate the AOTC, the following formula can be used:

AOTC = 100% of the first $2,000 of qualified education expenses + 25% of the next $2,000 of qualified education expenses

The maximum amount of AOTC that can be claimed per eligible student is $2,500.

To determine the AOTC that Janie's parents can claim, we first need to calculate their Modified Adjusted Gross Income (MAGI). MAGI is calculated by adding certain deductions back to their AGI. Assuming they have no deductions, their MAGI would be the same as their AGI, which is $177,600.

Since the tuition and fees paid by Janie's parents ($11,100) are less than $4,000, they can claim the full AOTC of $2,500.

We can break down the problem into two parts: first, calculating the amount of bonds payable that are due on September 30, 2026 (the first installment), and second, calculating the amount of bonds payable and interest payable that are due on any other date.

Bond payable due on September 30, 2026:

The total amount of bonds payable outstanding is $119,588,000. The installment due on September 30, 2026 is $29,897,000. Therefore, the amount of bonds payable that is due on September 30, 2026 is:

$29,897,000

Bond payable and interest payable due on any other date:

The total amount of bonds payable outstanding is $119,588,000. The first installment of $29,897,000 is due on September 30, 2026, which leaves $89,691,000 of bonds payable outstanding.

The bonds pay 12% interest every September 30th, so we need to calculate the interest payable for the period from September 30, 2026 to any other date. Let's assume we want to calculate the bond payable and interest payable due on December 31, 2026 (the end of the year).

The period from September 30, 2026 to December 31, 2026 is 92 days (or 3 months). The annual interest rate is 12%, so the daily interest rate is:

12% / 365 = 0.0328767%

The interest payable for 92 days is therefore:

$89,691,000 x 0.0328767% x 92/365 = $622,578.19

Adding this to the outstanding bonds payable gives:

Bond payable (other than 09/30/2026 installment) = $89,691,000 + $622,578.19 = $90,313,578.19

The dividends per share on preferred stock for four years is $0.12, $0.12, $0.12, $0.12 and for common stock is $0.057, $0.152, $0.220, $0.220.

To calculate the dividends per share for each class of stock, we need to first determine the total dividends paid in each year.

For the preferred stock, the dividends are cumulative, which means any unpaid dividends from previous years must be paid before any dividends can be paid to common stockholders. Therefore, we need to calculate the total amount of unpaid dividends for each year before we can determine the amount available for common stockholders.

To calculate the unpaid dividends for the preferred stock in each year, we need to multiply the number of shares of preferred stock by the dividend rate (3%) and subtract the dividends paid in that year.

Unpaid dividends for preferred stock:

1st year: (80,000 x $20 x 0.03) - $33,000 = $9,600

2nd year: (80,000 x $20 x 0.03) - $72,000 - $9,600 = $9,600

3rd year: (80,000 x $20 x 0.03) - $100,000 - $9,600 = $9,600

4th year: (80,000 x $20 x 0.03) - $100,000 - $9,600 = $9,600

Now we can calculate the total dividends available for common stockholders in each year by subtracting the unpaid dividends for preferred stock from the total dividends paid in that year.

Total dividends available for common stockholders:

1st year: $33,000 - $9,600 = $23,400

2nd year: $72,000 - $9,600 = $62,400

3rd year: $100,000 - $9,600 = $90,400

4th year: $100,000 - $9,600 = $90,400

Finally, we can calculate the dividends per share for each class of stock by dividing the total dividends by the number of shares outstanding.

Dividends per share:

Preferred stock:

1st year: $9,600 / 80,000 = $0.12 per share

2nd year: $9,600 / 80,000 = $0.12 per share

3rd year: $9,600 / 80,000 = $0.12 per share

4th year: $9,600 / 80,000 = $0.12 per share

Common stock:

1st year: $23,400 / 410,000 = $0.057 per share

2nd year: $62,400 / 410,000 = $0.152 per share

3rd year: $90,400 / 410,000 = $0.220 per share

4th year: $90,400 / 410,000 = $0.220 per share

Therefore, the dividends per share on each class of stock for each of the four years are as follows:

Preferred stock (dividends per share)

1st Year: $0.12 per share

2nd Year: $0.12 per share

3rd Year: $0.12 per share

4th Year: $0.12 per share

Common stock (dividends per share)

1st Year: $0.057 per share

2nd Year: $0.152 per share

3rd Year: $0.220 per share

Per week, because Justine travels 20 miles a day, Monday to Thursday is 4 days. To figure this out, we would simply need to divide.

[tex]4\times20[/tex]

[tex]80[/tex]

On Friday, adding on the 50 miles:

[tex]80+50[/tex]

[tex]130[/tex]

Knowing that Justine travels 110 miles per week, we have to calculate the amount in 3 weeks:

[tex]130\times3[/tex]

[tex]390[/tex]

Therefore, Justine traveled 390 miles.

Thanks.

The quantity of water in milliliters left in the water bottle after pouring 400 milliliters of water in glass is 4100 milliliters.

Milliliter is the smaller unit of quantity in the SI unit. One liter is equal to thousand times of one milliliter. It is given that the bottle contains 4.5 liters of water which means there is 4500 milliliters of water in it. Since Kevin pours 400 milliliters of water in the glass, this means 400 milliliters was emptied from the water bottle and hence the remaining amount can be calculated by subtracting the amount of water taken out from the bottle from the total amount.

Therefore the arithmetic equation will be as follows:

Amount of water left in bottle = Total quantity of water in the bottle - Water emptied out

Amount of water left in bottle = 4500 - 400 = 4100 milliliters

After dilatiοn , the cοοrdinates are  J'(-2,2), K'(2,2) , L'(4,4) and  M'(0,4).

Resizing an item uses a transitiοn called dilatiοn. Dilatiοn is used tο enlarge οr cοntract the items. The result οf this transfοrmatiοn is an image with the same shape as the οriginal. Yet, there is a variatiοn in the shape's size. The initial shape shοuld be stretched οr cοntracted during a dilatatiοn. The phrase "scale factοr" describes this transitiοn.

Here the given vertices cοοrdinate οf the image is

J(-4,4) , K(4,4) , L(8,8) and M(0,8).

Scale factor = [tex]\frac{1}{2}[/tex]

If the coordinate (x,y) and scale factor k then dilation of coordinate is (kx,ky). Then,

=> J(-4,4) --> J'[tex](\frac{1}{2}\times -4,\frac{1}{2}\times 4)[/tex] = J'(-2,2).

=> K(4,4) --> K'[tex](\frac{1}{2}\times 4,\frac{1}{2}\times 4)[/tex] = K'(2,2)

=> L(8,8) --> L'[tex](\frac{1}{2}\times 8,\frac{1}{2}\times 8)[/tex] = L'(4,4)

=> M(0,8) --> M'[tex](\frac{1}{2}\times 0,\frac{1}{2}\times 8)[/tex] = M'(0,4).

Hence after dilation the coordinates are  J'(-2,2), K'(2,2) , L'(4,4) and  M'(0,4).

If m LM = 105°, then m KL = 75° because opposite angles in a parallelogram are congruent.

If m LA = 70°, then m KLA = 110° because consecutive angles in a parallelogram are supplementary. Therefore, m ALK = 70°.

If m LK = 120°, then m KAL = 60° because consecutive angles in a parallelogram are supplementary. Therefore, m ALM = 120°.

If XE = 12 cm and diagonals XL and EA bisect each other at O, then AO = OL = 6 cm because the diagonals of a parallelogram bisect each other.

Using the parallelogram law, AL² = AX² + XL² + 2(AX)(XL)cos(LAX), and since LAX is congruent to LEX, we have cos(LAX) = cos(LEX) = -1/2. Substituting the given values and solving for AL, we get AL = sqrt(421) cm.

If AX = 15 cm, then LX = EA = 15/2 = 7.5 cm because the diagonals of a parallelogram bisect each other. Using the Pythagorean theorem, we have LE² = LX² + XE² and substituting the given values, we get LE = sqrt(193.5) cm.

If XO = 5 cm, EO = 6 cm, and diagonals XL and EA bisect each other at O, then AO = OL = 5 cm and XL = EA = 2AO = 10 cm because the diagonals of a parallelogram bisect each other.
