The height of the house with an angel of elevation 25° from the line of sight of the observer is equal to 10 ft to the nearest foot.

The angle of elevation is the angle between the horizontal line and the line of sight which is above the horizontal line.

The height of the house is the sum of length from her eyes to the ground and the perpendicular length from her eyes to the top of the house.

we shall represent the perpendicular length from her eyes to the top of the house with x so that;

tan 25° = x/11 {opposite/adjacent}

x = 11 × tan 25°

x = 5.1294

height of the house = 5 ft + 5.1294 ft

height of the house = 10.1294 ft

Therefore, the height of the house with an angel of elevation 25° from the line of sight of the observer is equal to 10 ft to the nearest foot.

The width of the flower bed is approximately 1.4m.

To solve this problem, we need to use the formula for the area of a rectangle: A = L x W, where A is the area, L is the length, and W is the width.

Let's start by finding the area of the pond:
A pond = 10m x 7m = 70m^2

Next, we need to find the total area of the pond and the flower bed combined. We are given that this area is 180m^2:
A total = A pond + A flower bed
\(180m^2 = 70m^2 + A flower bed\)
\(110m^2 = A flower bed\)

Now we can use the formula for the area of a rectangle again to find the width of the flower bed:
A flower bed = L x W
\(110m^2 = (10m + 2x) (7m + 2x)\)
\(110m^2 = 70m^2 + 20xm + 14xm + 4x^2\)

Simplifying and rearranging, we get:
\(4x^2 + 34xm + 40m^2 - 110m^2 = 0\)
\(4x^2 + 34xm - 70m^2 = 0\)

Dividing both sides by 2, we get:
\(2x^2 + 17xm - 35m^2 = 0\)

Now we can use the quadratic formula to solve for x:
\(x= \frac{-b±\sqrt{(x^{2})-4ac } }{2a}\)
Where a = 2, b = 17m, and \(c = -35m^2\).

Plugging these values in, we get:
\(x =\frac{ (-17m ± \sqrt{17(m)^{2}+280(m)^{2}  } }{4}\)
\(x= \frac{(-17m ±\sqrt{697} )}{4}\)

Since the width of the flower bed can't be negative, we take only the positive root:
\(x= \frac{(-17m +\sqrt{697} )}{4}\)
x = 1.4m

Therefore, the width of the flower bed is approximately 1.4m.

The distribution of the given function is a uniform distribution.

A strictly increasing function is the one which increases continuously in a given interval. If f-1(u) is a strictly increasing function of u, then the distribution of f-1(u) is the same as that of u. This is because a strictly increasing function preserves the rank ordering of its input, so if u-1 and u-2 are two random variables with a uniform distribution on the interval (0,1), then the rank order of f-1(u-1) and f-1(u-2) will be the same as the rank order of u-1 and u-2. Since the uniform distribution is defined by the rank order of its values, this means that the distribution of f-1(u) is also uniform on the interval (0,1).

Answer: kindly check explanation

Step-by-step explanation:

Given the following :

Charge for bike rental :

initial price = $15

Additional charge = $0.75 per hour

Expression to model the above :

15 + 0.75h

The variable H represents The cost per hour? Or the number of hours?

The variable h in the expression is the number of hours,

Since the additional charge rate is $0.75 per hour, $0.75 for each hour of bike rental

The constant 15 represents the initial rental price or the number of hours?

$15 represents the initial price being paid to rent a bike

The variable term 0.75h represents, the hourly rental amount or the number of hours?

Multiply the amount charged per hour by the number of hours gives us the total additional amount charged for the number of hours biked

The expression that can be used to solve the question will be H = 15 + 0.75h.

The expression to solve the question will be H = 15 + 0.75h.

where,

Therefore, let's say we want to find the cost for 4 hours. This will be:

H = 15 + 0.75h.

H = 15 + 0.75(4)

H = 15 + 3

Amount of money in the savings account after 5 years.

To calculate the amount of money in a savings account after a certain number of years with annual interest compounded monthly, you can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:
A = the final amount
P = the principal (initial amount)
r = annual interest rate (as a decimal)
n = number of times the interest is compounded per year
t = number of years

Let's assume the principal amount is $1,000, the annual interest rate is 5%, and the interest is compounded monthly (n = 12).

Using the formula, we have:
A = 1000(1 + 0.05/12)^(12t)

Now, let's say we want to calculate the amount after 5 years.

A = 1000(1 + 0.05/12)^(12*5)

Calculating this expression will give you the approximate amount of money in the savings account after 5 years.

Matrix-vector multiplication is a linear operation because it satisfies the properties of scalar multiplication and vector addition, which are a(u+v) = au + av and a(cu) = cau, where a is a scalar and u and v are vectors.

Matrix-vector multiplication is a fundamental operation in linear algebra, where a matrix is multiplied by a vector to produce another vector. This operation is considered linear because it adheres to certain properties.

The first property is scalar multiplication, which states that multiplying a vector u by a scalar a and adding it to another vector v (a(u+v)) is equivalent to multiplying u by a (au) and v by a (av) separately and then adding the results (au + av). In other words, the operation distributes over vector addition.

The second property is the distributive property of scalar multiplication, which states that multiplying a vector u by a scalar c and then multiplying the resulting vector (cu) by another scalar a is equivalent to multiplying u by the product of the two scalars (cau). This property allows the scalar multiplication to be distributed over scalar multiplication.

These properties ensure that matrix-vector multiplication preserves the linearity of the underlying vector space. They enable the manipulation and analysis of systems of linear equations, transformations, and other mathematical operations involving matrices and vectors.

The average distance that the airplane covered in three flights is = 2036 kilometers,

From Hong Kong to Manila travel time is = 1.468 hours,

From Singapore to Manila travel time is = 3.146 hours,

From Korea to Manila travel time is = 3.422 hours and the trip from Korea to Manila took longest time to travel.

The distance a plane traveled over three separate trips:

Hongkong-Manila : 1116 kilometers,

Singapore-Manila : 2391 kilometers,

Korea-Manila : 2601 kilometers.

We must determine the average distance covered by the aircraft over the course of the three journeys, the time required for each trip if the aircraft is traveling at 760 km/h, and the trip that took the longest.

The average distance flown by the aircraft across the three trips

= \(\frac{1116+2391+2601}{3}\)

= \(\frac{6108}{3}\)

= 2036 kilometers

We know that,

Speed = distance/time.

So,

We can write,

Time = Distance/speed

From Hong Kong to Manila travel time = 1116/760

= 1.468 hours

From Singapore to Manila travel time = 2391/760

= 3.146 hours

From Korea to Manila travel time = 2601/760

= 3.422 hours

We can observe that the trip from Korea to Manila took longest time to travel.

Therefore,

The average distance that the airplane covered in three flights is 2036 kilometers,

From Hong Kong to Manila travel time is 1.468 hours,

From Singapore to Manila travel time is 3.146 hours,

From Korea to Manila travel time is 3.422 hours and the trip from Korea to Manila took longest time to travel.

Step-by-step explanation:

The degree of operating leverage, degree of financing leverage, and the degree of total leverage for Trident Foods is 2.78, 4.52, and 12.57.

So, the correct answer is D.

Degree of operating leverage can be defined as the percentage change in net operating income divided by the percentage change in sales.

The formula for Degree of Operating Leverage is as follows;

Percentage change in net operating income / percentage change in sales.

Using the above formula;

Percentage change in net operating income = EBIT (Earnings before interest and taxes) × percentage change in sales Percentage change in net operating income = $13,500 × (Sales revenues)

Degree of operating leverage = Percentage change in net operating income / percentage change in sales

Degree of operating leverage = $13,500 / $150,000 = 0.09 or 9% (Rounded off to two decimal places)

Degree of financing leverage is the percentage change in EPS (Earnings per share) for a given percentage change in EBIT (Earnings before interest and taxes).

The formula for Degree of Financing Leverage is as follows;

Percentage change in EPS / percentage change in EBIT.

Using the above formula;

Percentage change in EPS = percentage change in EBIT × (EBIT − Interest) − Taxes (1 − Tax rate)

Percentage change in EPS = EBIT / Interest × (EBIT − Interest) − Taxes (1 − Tax rate)

Average number of shares

Percentage change in EPS = $13,500 / $10,000 × ($13,500 − $10,000) − $1,400(1 − 0.4) / 4,000

Percentage change in EPS = 0.35 or 35% (Rounded off to two decimal places)

Degree of Total Leverage is the percentage change in EPS (Earnings per share) for a given percentage change in sales.

The formula for Degree of Total Leverage is as follows;

Percentage change in EPS / percentage change in sales

Using the above formula;

Percentage change in EPS = Percentage change in EBIT × Degree of financing leverage

Percentage change in EPS = 0.09 × 3.86Percentage change in EPS = 0.3474 or 34.74% (Rounded off to two decimal places)

Degree of Total Leverage = Percentage change in EPS / percentage change in sales

Degree of Total Leverage = 0.3474 / 0.027 = 12.57 (Rounded off to two decimal places)

Therefore, the degree of operating leverage, degree of financing leverage, and the degree of total leverage for Trident Foods is 2.78, 4.52, and 12.57. The correct option is (d).

The values of Z such that e² = 2 + i√3 are Z = ln(2 + i√3) + 2πik, where k is an integer.

To find the values of Z, we can start by expressing 2 + i√3 in polar form. Let's denote it as re^(iθ), where r is the modulus and θ is the argument.

Given: 2 + i√3

To find r, we can use the modulus formula:

r = sqrt(a^2 + b^2)

= sqrt(2^2 + (√3)^2)

= sqrt(4 + 3)

= sqrt(7)

To find θ, we can use the argument formula:

θ = arctan(b/a)

= arctan(√3/2)

= π/3

So, we can express 2 + i√3 as sqrt(7)e^(iπ/3).

Now, we can find the values of Z by taking the natural logarithm (ln) of sqrt(7)e^(iπ/3) and adding 2πik, where k is an integer. This is due to the periodicity of the logarithmic function.

ln(sqrt(7)e^(iπ/3)) = ln(sqrt(7)) + i(π/3) + 2πik

Therefore, the values of Z are:

Z = ln(2 + i√3) + 2πik, where k is an integer.

The values of Z such that e² = 2 + i√3 are Z = ln(2 + i√3) + 2πik, where k is an integer.

Yes, quadrilateral ABCD is a parallelogram.

What are the properties of parallelogram?

A parallelogram is a particular sort of polygon. It is a quadrilateral in which the opposite side pairs are parallel to one another.

Properties:

1. Opposite sides are congruent.

2. Opposite angels are congruent.

3. Consecutive angles are supplementary.

4. If one angle is right, then all angles are right.

5. The diagonals of a parallelogram bisect each other.

6. Each diagonal of a parallelogram separates it into two congruent

It is given that the coordinates of the vertices of quadrilateral ABCD are A (8, -3), B(-2, 1), C (-4,-4), and D(6, -8).

According to distance formula,

If A(a,b) and B(x,y) are two coordinates then

AB = \(\sqrt{(x-a)^{2}+(y-b)^{2}}\)

Now, using this distance formula in quadrilateral ABCD

AB = \(\sqrt{(-2-8)^{2}+(1+3)^{2}}= \sqrt{(-10)^{2}+(4)^{2}}=\sqrt{100+16}=\sqrt{116}\)

CD = \(\sqrt{(6+4)^{2}+(-8+4)^{2}}=\sqrt{10^2+(-4)^2}=\sqrt{100+16}=\sqrt{116}\)

Now, If we have two coordinates A(a,b) and B(x,y) then

Slope of AB = \(\frac{y-b}{x-a}\)

Using this formula , finding slope of AB and CD of quadrilateral ABCD we get ,

Slope of AB = \(\frac{1+3}{-2-8}=\frac{4}{-10}=\frac{2}{-5}\)

Slope of CD = \(\frac{-8+4}{6+4}=\frac{-4}{10}=\frac{-2}{5}\)

As slope of both AB and CD is equal therefore, we can say that AB and CD are parallel.

As AB = CD and AB is parallel to Cd Therefore, ABCD is a parallelogram as opposite sides of parallelogram are equal and parallel.

Hence, quadrilateral ABCD is a parallelogram.
