The diagonals of parallelogram ABCD intersect at E. If AE=2x+ 4., EB=6+3y,EC=15-y and ED =x+4 then, find the lengths of diagonals AC and BD.

The value of x in this isosceles triangle is equal to: D. 50.

In Mathematics and Geometry, an isosceles triangle simply refers to a type of triangle with two (2) sides that are equal in length and two (2) equal angles.

This ultimately implies that, an isosceles triangle comprises two (2) side lengths that are equal and two (2) angles with the same magnitude.

In isosceles triangle ABC, side DE intersects its congruent sides and is parallel to side AB. Therefore, there are two sides that are congruent (equal) and as such we have;

(54 - 2x)° = (3x + 4)°

3x - 2x = 54 - 4

x = 50

Answer: To calculate the sales growth, we need to find the difference between the current year's revenue and the last year's revenue, divide it by the last year's revenue, and then multiply by 100 to convert it to a percentage.

Sales Growth = ((Sales Revenue Current Year - Sales Revenue Last Year) / Sales Revenue Last Year) x 100%

Sales Growth = (($150,000 - $125,000) / $125,000) x 100%

Sales Growth = ($25,000 / $125,000) x 100%

Sales Growth = 0.20 x 100%

Sales Growth = 20%

Therefore, the sales growth is 20%.

Therefore , the solution of the given problem of equation comes out to be it took the aircraft roughly 0.156 hours, or 9.36 minutes, to fly 3,008 miles at a constant speed of 470 miles per hour.

Variable words are commonly used in complex algorithms to show consistency between two contradictory claims. Academic expressions called equations are used to show the equality of various academic numbers. In this case, normalization produces b + 7, in contrast to another algorithm, which can evaluate data from y + 7, divides 12 through two components, and produces y + 7.

Here,

The formula Hayden created is:

=> 470/h = 3008

We must separate h on one side of the equation in order to solve for it. By increasing both parts of the equation by h, we can achieve this:

=> 470 = 3008h

Then, to get h on its own, split the two sides of the equation by 3008:

=> h = 470/3008

By dividing the numerator and denominator by their 2 largest common factor, we can simplify this fraction:

=> h = 235/1504

Therefore, it took the aircraft roughly 0.156 hours, or 9.36 minutes, to fly 3,008 miles at a constant speed of 470 miles per hour.

The expression for time will be, Time = 5/r + 10/w.

What exactly are expressions?

In mathematics, an expression is a combination of numbers, symbols, and operators that represent a value or a computation.

Expressions can be simple or complex, and they can contain variables, constants, and functions. They can be evaluated to produce a single value, or they can be simplified or transformed using mathematical rules and operations.

Now,

Let's assume that Juan ran at a speed of "r" miles per minute, and let's also convert the 10 minutes of walking to miles per minute by dividing by the walking speed "w".

Then, the total time Juan spent exercising can be expressed as:

Time = Time Running + Time Walking

Time Running = Distance / Speed = 5 / r

Time Walking = 10 / w

Therefore,

Step-by-step explanation:

Here is how to do the first one....the others are similar

f(x) = x/2       when x = -4,     f(-4) = -4/2 = -2    (just put the number in for 'x')

                 when x = - 2 ,   f(-2) =  -2/2 = -1

The function f(x) = 3x + 3 - x is neither even nor odd.

The y-axis of the function k's graph is symmetric. This is apparent because, if we reflect any point on the graph across the y-axis, we will obtain a second point on the graph. For purposes of formal definition, the function k is even since k(-x) = k(x) for every x within the range of k.

If the function f(x) = 3x + 3 - x fits the requirements for even or odd functions, we may determine whether it is even, odd, or neither.

Being symmetric around the y-axis means that an even function has f(-x) = f(x) for every x falling inside its domain.

An odd function is symmetric around the origin, which means that for any x falling within the domain of f, f(-x) = -f(x).

We evaluate f(-x) and f(x) to see if they are equivalent in order to determine whether f(x) is even:

f(x) = 3x + 3 - x = 2x + 3 while f(-x) = 3x + 3 - x = -2x + 3

The function f(x) is not even since f(-x) is not equal to f(x).

We assess f(-x) and -f(x) and see if they are equivalent to determine whether f(x) is odd:

F(x) = -3(x) + 3(x) - (x) = -2x + 3 F(x) = -(3x + 3(x) - x) = -2x - 3

The function f(x) is not weird since f(-x) does not equate to -f(x).

The function f(x) = 3x + 3 - x is therefore neither even nor odd.

If the DVD is marked 10% off, it means the price of the DVD has been reduced by 10% of its original price.

To calculate the amount of the discount, we need to find 10% of the original price. We can do this by multiplying the original price by 10% written as a decimal:

10% as a decimal = 0.10

Amount of discount = 0.10 x $15 = $1.50

Working with M and N;

Sin 15 / x = Sin 90 / 12

From the given question, the value of the height of the cone is given by 57.3 centimeters to the nearest 1 decimal place: Option B

We should note that a cone is a three-dimensional geometric figure with a flat and curved surface pointed towards the top.  It is formed by using a set of line segments or the lines which connects a common point, called the apex or vertex, to all the points of a circular base(which does not contain the apex)

The volume of the cone is given by the formula

Volume = 1/3πr²h

Where Volume = 1500 centimeters cube, radius = 5 cm, π = 22/7

1500 = 1/3*22/7*5*5*h

1500 = (22*5*5*h)/3*7

Simplifying the expression further we have

1500 = 550h/21

1500(21) = 550h

31500 = 550h

Making h the subject of the relation we have

h = 31500/550

The expression is undefined when x = 9. the expression will be undefined when x-9 = 0.

To find the values of x for which the expression is undefined, we need to look for values of x that would make the denominator of the expression equal to zero. In this case, the denominator is x-9. Therefore, the expression will be undefined when x-9 = 0. Solving for x, we get x = 9.

When x is equal to 9, the denominator becomes zero, which would make the expression undefined as dividing by zero is undefined in mathematics. For all other values of x, the expression is defined and can be evaluated.

We can verify this by substituting x = 9 in the expression and observing that it becomes (9² - 36)/(9-9), which is (81-36)/0, and division by zero is undefined.

y = mx + b

5 = 2(3/4) + b

5 = 3/2 + b  Subtract 3/2 from both sides

5 - 3/2 = 3/2 -3/2 +b

Parallel slopes are equal so the slope will be 3/4.  Now we will use the x and y values from the point (5,1) to find the y-intercept.  We will use 1for y and 5 for x

y = mx + b

1 = 5(3/4) +b

1 = 15/4 + b  Subtract 15/4 from both sides.

[tex]\frac{4}{4}[/tex] - [tex]\frac{15}{4}[/tex] = [tex]\frac{15}{4}[/tex] - [tex]\frac{15}{4}[/tex] + b

We need to calculate the height h of point B above point A. To begin, we may use the tangent function to get the heights of points C and E:

[tex]hC = 16 * tan(θ1)\\hE = 16 * tan(θ2)\\DE = hE - hC\\hB = hC + DE * tan(θ2)\\h = hB + 1.5\\θ1 = 41\\θ2 = 49\\DE = 16 * (tan(θ2) - tan(θ1)) ≈ 9.7587 m\\hC = 16 * tan(θ1) ≈ 12.2272 m\\hB = hC + DE * tan(θ2) ≈ 23.7333 m\\h ≈ hB + 1.5 ≈ 25.2333 m\\[/tex]

As a result, the antenna's height is roughly 25 metres.
