From atop a 15 m lighthouse, a man spots a dolphin 50 m out to sea. Find the angle of depression from the man to the dolphin, to nearest degree.

Therefore , the solution of the given problem of ratio comes out to be  300,000.

A portion or fraction in mathematics displays how frequently one number is included in another. For instance, if there are eight orange and six lemons in a fruit plate, the proportion of oranges to lemonade is eight to six, or 8:6, which is comparable to the ratios 4:3 or the decimal 1.333.

Here,

We must use our grasp of proportionality to establish the maximum amount of shares that can be owned in this exercise.

The 20 huge variations will allow Blackbird Oil to store a total of 300,000 gallons.

The details in the assertion can be summed up as follows:

20 brand-new, sizable oil storage tanks.

The ratio is 4:5 for 12,000 gallons.

Because of the proportional ratio of 4.05, the enormous receptacles are 1.25 times larger than the ordinary ones, giving us:

=> 1200 * 1.25 = 15000

=> 15000 * 20 = 300000

As a result, the supplied problem's answer equals 300,000.

The vertex is (5,-9)

A vertex is a point on a polygon where two rays or line segments meet, the sides, or the edges of the object come together. Vertex is the plural form of vertices.

The function is given as f(x) = (x - 8) (x - 2)

Taking the parentheses out

f(x) = x2 - 2x - 8x + 16

f(x) = x2 - 10x + 16

The function's vertex is (h, k)

h = -b / 2a

Changing the values

h = - (-10) / 2 (1) (1)

h = 10 / 2

the x coordinate for h = 5

changing the quadratic function's x value

f(5) = (5 - 8) (5 - 2) (5 - 2)

f(5) = (-3) (3) (3)

f(5) = k = -9

Consequently, the vertex is (5, -9).

(a) At the top of the ride, her apparent weight is 518.5 N. This is because, at the top of the ride, the centripetal force acting on her is directed towards the center of the Ferris wheel, which acts in opposition to her weight. Since her weight is 520 N, and the centripetal force is 1.5 N, the net force acting on her is 518.5 N.

Apparent weight, also known as effective weight or net weight, is the weight that an object appears to have when it is in motion. It is the force that an object feels as a result of a combination of its true weight and any additional forces acting on it, such as the centripetal force.

(b) At the bottom of the ride, her apparent weight is 520.5 N. This is because, at the bottom of the ride, the centripetal force acting on her is in the same direction as her weight, so the net force acting on her is the sum of her weight and the centripetal force.

(c) The radius of the Ferris wheel can be determined using the formula v^2 = r * g, where v is the angular velocity, r is the radius and g is the acceleration due to gravity. Given that angular speed and the apparent weight is known, you can use this formula to find the radius.

Answer and Explanation: To get the two terms on the right to combine into one term, we need the denominators of both terms to be the same. To do this we can plug in x+3 for the bottom left denominator and x-4 for the bottom right denominator. This makes both denominators (x+3)(x-4).

The numerators of both terms on the right just have to add up to 3x-2. One way we could do this is to the right one as 3x and the other as -2 or vice versa.

(x+3)(x-4) simplifies to x^2-x-12 which is why the denominator of the term on the left is that.

Answer:

3.75 cm²

Step-by-step explanation:

Area of a triangle = 1/2bh = 1/2(2.5)(3) = 3.75 cm²

The Fourier series coefficients for T-2 and A-4 are Ao = 2, B(n-odd) = 0, and B(n-even) = -(4/nπ). The Fourier series for the function is then given by:Y(t) = A0 + ΣB(n)cos(nπt/T) + ΣB(n)

The Fourier series coefficients are used to determine the Fourier series of a given function. The Fourier series is an infinite series of sines and cosines which, when summed, gives an approximation of the original function.

The coefficients are determined by integrating the function over a period and solving for the coefficient of each term.

The coefficients for the function T-2 and A-4 are determined by first calculating the period of the function. The period of the function is T=4. The coefficients are then calculated by integrating the function from 0 to T and solving for each coefficient. The coefficients for T-2 and A-4 are then calculated as follows:

A0= 2

B(n-odd) = 0

B(n-even) = -(4/nπ)

Therefore,

Y(t) = A0 + ΣB(n)cos(nπt/T) + ΣB(n)

System Linear equation has no solution , because it is paralell lines but no intersection.

What is system linear equation?

An equation for a line is known as a linear equation. alternatively, y + 0.5x 3.5 = 0 and others. (Note that each linear equation is the same.) When multiple linear equations interact, we get a system of linear equations.

Here the given system linear equations,

[tex]3y=\frac{3}{2}x+6[/tex] -------> 1    and [tex]\frac{1}{2}y-\frac{1}{4}x=3[/tex] --------> 2

Divide by 3  of equation 1 on both sides then,

[tex]y=\frac{1}{2}x+2[/tex]  -----------> 3

Now put 3 into 2 then,

=> [tex]\frac{1}{4}x+1-\frac{1}{4}x=3[/tex]

=> 1=3

The greatest possible error of 4700 is equal to 2,350.

In Mathematics, precision can be defined as a quality which is independent of accuracy because it only describes how close together are numerical values that are obtained in a series of measurements.

In Mathematics, the greatest possible error (GPE) of a measurement can be defined as one-half of the value of a given smallest measuring unit, or one-half of a given precision.

This ultimately implies that, the greatest possible error (GPE) of a measurement can calculated by dividing the precision by two and this is represented by this mathematical expression;

Greatest possible error (GPE) = precision/2

Greatest possible error (GPE) = 4700/2

What is the arithmatic calcaltion?

Arithmetic is a branch of mathematics that deals with the manipulation of numbers and the properties of operations such as addition, subtraction, multiplication, and division. It is often referred to as "elementary mathematics" or "number theory" and is one of the oldest and most basic branches of mathematics.

If 5/7 of the runners at the festival are women, we can use this information to find how many runners are women.

Let's call the number of women runners W. We know that 5/7 of the runners are women, so we can set up the following proportion:

W / 1050 = 5/7

To find the value of W, we can cross-multiply and then solve for W:

W * 7 = 5 * 1050

W = 750

Hence, there are 750 women runners at the festival out of 1050 runners.

The cost of 4.25kg of potatoes will be £2.38

A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 4(for every one boy there are 3 girls) 1 / 4 are boys and 4 / 5 are girls. 0.20 are boys (by dividing 1 by 5). It can also be defined as the size, number, or amount of one thing or group as compared to the size, number, or amount of another.

The cost of 2.5kg of potatoes is £1.40

Therefore the cost of 1kg potatoe = 1.40/2.5 = £0.56

This means that the cost of 4.25 kg = 0.56× 4.25
