Which statements about the function y = x ^ 2 - 6x + 8 are true?

The height of the building is approximately 62.4369 feet. The solution involves using trigonometry and solving for the opposite side of the triangle using the tangent function.

Let h be the height of the building, and x be the distance between the first point and the base of the building. Then we have:

tan(26.8°) = h/x ----(1)

tan(19.5°) = h/(x + 43.9) ----(2)

From equation (1), we have x = h/tan(26.8°)

Substituting this value of x in equation (2) and solving for h, we get:

h = (43.9 tan(19.5°) tan(26.8°))/(tan(26.8°) - tan(19.5°))

Plugging in the values, we get:

h ≈ 62.4369 feet

Therefore, the height of the building is approximately 62.4369 feet.

Answer:

it is given that diagram shows part of the Wheel of Theodorus. graphics for exercise 20 page 428 geometry part (a). It is required to identify which ...

Step-by-step explanation:

For part A the length of the perpendicular is approximately 156.18. Length of GH, the area of the rectangle is approximately 12336.22 square units.

FOR Part B the length of the perpendicular is approximately 182.48.

the area of the triangle is approximately 8954.96 square units.

How to solve the question?

To find the perpendicular of a right triangle, we need to use the Pythagorean theorem, which states that the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

Let the length of the perpendicular be h, and the length of the other leg of the triangle be b. Then, we can set up the equation:

175²= h²+ 79²

Simplifying, we get:

30,625 = h²+ 6,241

Subtracting 6,241 from both sides, we get:

24,384 = h²

Taking the square root of both sides, we get:

h ≈ 156.18

Therefore, the length of the perpendicular is approximately 156.18.

The area of a rectangle is given by the formula:

Area = length × width

Substituting the given values, we get:

Area = 156.18 × 79

Area = 12336.22 square units

Therefore, the area of the rectangle is approximately 12336.22 square units.

To find the perpendicular, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. In this case, we know the length of the hypotenuse and one of the other sides, so we can solve for the length of the perpendicular.

Using the Pythagorean theorem:

h²= b²+ p²

where h is the length of the hypotenuse, b is the length of the base, and p is the length of the perpendicular.

Substituting the given values:

207²= 98²+ p²

Simplifying:

42849 = 9604 + p²

Subtracting 9604 from both sides:

33245 = p²

Taking the square root of both sides (since p is a length, we only take the positive square root):

p = sqrt(33245)

p ≈ 182.48

Therefore, the length of the perpendicular is approximately 182.48.

To find the area of the triangle, we can use the formula:

Area = (1/2) x base x height

Substituting the given values:

Area = (1/2) x 98 x 182.48

Simplifying:

Area = 0.5 x 98 x 182.48

Area ≈ 8954.96

Therefore, the area of the triangle is approximately 8954.96 square units.

The combined total of his annual contribution and his employer's contribution is $13,000.

The term "combined total" refers to the sum or aggregate of two or more individual quantities, values, or amounts. It represents the cumulative or total amount resulting from the combination or addition of multiple components.

According to the given information:

First, let's calculate Caleb's annual contribution to his 401k account.

Caleb contributes $250 from each biweekly paycheck, so his biweekly contribution is $250.

Since there are 26 biweekly pay periods in a year (52 weeks), his total biweekly contributions in a year would be 26 * $250 = $6,500.

Caleb's annual salary is $45,000 per year, and his employer matches 75% of his 401k contributions up to 10% of his annual salary. So, the maximum employer match would be 75% of 10% of $45,000, which is 0.75 * 0.10 * $45,000 = $3,375.

Since Caleb's annual contribution ($6,500) is less than the maximum employer match ($3,375), his employer will match his entire contribution.

Therefore, the combined total of Caleb's annual contribution and his employer's contribution would be $6,500 + $6,500 = $13,000.

The coordinate location of point C' after the dilation is (-10, 2).

What is coordinate location?

To find the coordinate location of point C' after the dilation by a scale factor of 4 about the center (-2,-2), we can use the following formula:

(x', y') = (k * (x - h) + h, k * (y - k) + k)

where (x, y) are the coordinates of the original point, (h, k) are the coordinates of the center of dilation, k is the scale factor, and (x', y') are the coordinates of the corresponding point after dilation.

For point C, the coordinates are (x, y) = (-2, -1) and the center of dilation is (h, k) = (-2, -2) with a scale factor of k = 4.

Plugging in these values, we get:

(x', y') = (4 * (-2 - (-2)) - 2, 4 * (-1 - (-2)) - 2)

= (-10, 2)

Therefore, the coordinate location of point C' after the dilation is (-10, 2).

What is coordinate?

A coordinate is a set of numbers or values that indicate the position or location of a point or object in a given space or system. Coordinates are often used in mathematics, geometry, physics, and other fields to describe the location of objects or points in a two- or three-dimensional space. The most common type of coordinates are Cartesian coordinates, which are represented by an ordered pair of numbers (x,y) that describe the location of a point on a two-dimensional plane, or an ordered triplet of numbers (x,y,z) that describe the location of a point in a three-dimensional space.

A sector is a section of a circle in geometry that is bounded by two radii and an arc. It is a pie-shaped portion of a circle that touches the circle's center, has two straight edges (the two radius lines), and a curved edge created by the arc.

Arc Length = r is the formula for the arc length of a circle,

where is the radius of the circle and r is the radian measurement of the arc (or central angle).

The formula for arc length, L = r *, can be used to determine the value of zero. L is the length of the arc, r is the radius of the circle, and is the centre angle in radians. We can deduce from the facts provided that PQ equals 2 * OP.

Also obvious is that OR = 4 cm. We can claim that PQ = 2 * OR = 8cm because PQ is twice as long as OP. Now, we can calculate's value using the formula:

L = r * θ 8 = 4θ θ = 2

Consequently, = 2 radians.

We must know the length of arc RS in order to calculate the size of the shaded zone. PQ is twice RS, as we are aware. RS = PQ/2, which equals 4 cm. Now, we may apply the area of a formula.We may now apply the formula A = (1/2) * r² *, where A is the sector's area, r is the circle's radius, and is the centre angle in radians.

Sector PQR area equals (1/2) * OR2 * sector PQR area equals (1/2) * 16 * 2 sector PQR area equals (16)

Sector PSR area equals (1/2) * OR²2 * Sector PSR area equals (1/2) * 16 * π/3 Sector PSR area equals (8)/3

The net loss is $1873.97.

What is the selling price?

The selling price formula is Selling Price = Cost Price + Profit Margin. Cost price is the price a retailer paid for the product. The profit margin is a percentage of the cost price.

Here, we have

Given: Suki purchased $9,600 worth of stock and paid her broker a 2.5% broker fee. She had an immediate need for cash and was forced to sell the stock when it was worth $8,000. She used a discount broker who charged $33.97 per trade transaction.

Purchase price: $9,600

Fee purchase:  2.5%

Selling price: $8,000

Fee scale: $33.97

The broker fee is the product of the broker fee rate of  2.5% and the purchase price:

Broker fee purchase = 2.5%× 9,600

= 240

The total purchase cost is the sum of the purchase price and the broker fee of the purchase:

Total purchase cost Purchase price =  Broker fee purchase

= 9600 + 240

= 9840

The total selling cost is the selling price decreased by the broker fee of the sale (flat rate):

Total selling cost = Selling price - Broker fee sale

= 8,000 - 33.97

= 7966.03

The net loss is then the difference between the total purchase cost and the total selling cost:

Net loss = Total purchase cost - Total selling cost

The event where two or more things happen at the same time is called a "compound event."  the correct answer is B.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.

A compound event refers to a situation where two or more events occur at the same time. In other words, it is an event that consists of multiple outcomes happening simultaneously.

For example, if you flip a coin and roll a dice at the same time, the resulting event would be a compound event because it involves the outcomes of both actions occurring simultaneously. It is important to distinguish between compound events and independent or dependent events, as they have different probabilities and methods of calculation. Compound events are often used in probability theory and statistics to analyze and predict the likelihood of multiple outcomes occurring at the same time.

Therefore, the width of the rectangle is 10.

So, the answer is (O) 10.

To find the width of a rectangle, you will need to have at least one of the following pieces of information:

Length and area: If you know the length and area of the rectangle, you can use the formula for area (A = length x width) and solve for the width (W = A/length).

Perimeter and length: If you know the perimeter and length of the rectangle, you can use the formula for perimeter (P = 2 x length + 2 x width) and solve for the width (W = (P - 2 x length)/2).

Diagonal and length: If you know the diagonal and length of the rectangle, you can use the Pythagorean theorem ([tex]a^2 + b^2 = c^2[/tex]) to solve for the width. [tex](W = \sqrt(c^2 - length^2)),[/tex] where c is the diagonal and a and b are the length and width (in some order).

Ratio of length to width: If you know the ratio of length to width, you can use this ratio to solve for the width. For example, if the ratio of length to width is 3:2, and the length is 15, then the width would be 10 (because 15/3 = 5 and 5 x 2 = 10).

Measurements: If you have physical access to the rectangle, you can measure the width directly using a ruler or tape measure.

Let's assume the length of the rectangle as "L" and the width as "W".

From the given information, we know that:

The area of the rectangle is 40, so we have the equation:

[tex]L x W = 40[/tex]

The width is 2 less than 3 times the length, so we have the equation:

[tex]W = 3L - 2[/tex]

Now we can substitute the second equation into the first equation and get:

[tex]L x (3L - 2) = 40[/tex]

Expanding the left-hand side, we have:

3L^2 - 2L - 40 = 0

Dividing both sides by 1, we get:

[tex]3L^2 - 2L - 40 = 0[/tex]

Using the quadratic formula, we get:

[tex]L = 4 or L = -10/3[/tex]

Since the length of a rectangle cannot be negative, we take L = 4.

Then, we can use the equation W = 3L - 2 to find the width:

Assume that m arc VUX = 228° and m ∠UVW = 121° in the circle below.

m∠VUX = 66° and m m∠UXW = 59° respectively.

1) The given information is;

The angle of arc m∠VUX = 228°, the measured angle of ∠UVW = 121°

Given that m∠VUX = 228°, therefore, arc ∠XWV = 360 - 228 = 132°

Therefore, the angle subtended by arc ∠XWV at the centre = 88°

The angle subtended by arc ∠XWV at the circumference = m∠VUX

∴ m∠VUX = 132°/2 = 66° (Angle subtended at the center = 2×angle subtended at the circumference)

m∠VUX = 66°

2) Similarly, m∠XWV is subtended by arc m∠VUX, therefore, m∠XWV = (arc m VUX)/2 = 228°/2 = 114°

A quadrilateral's angles add up to 360°.

Therefore;

m∠VUX + m∠XWV + m∠UVW + m∠UXW = 360° (The sum of angles in a quadrilateral XWVU)

m∠UXW = 360° - (m∠VUX + m∠XWV + m∠UVW)

m∠UXW = 360° - (66 + 114 + 121)

Step-by-step explanation:

Let's assume that the width of the rectangle is x. Then, according to the problem statement, the length of the rectangle would be 3x.

The area of a rectangle is given by the formula:

Area = Length x Width

Substituting the values of length and width in the formula, we get:

75 = (3x) x (x)

Simplifying the right-hand side, we get:

75 = 3x^2

Dividing both sides by 3, we get:

25 = x^2

Taking the square root of both sides, we get:

x = ±5

Since the width cannot be negative, we take the positive value of x, which is 5.

Therefore, the width of the rectangle is 5
