Given VXY and VWZ what is VW?

Answer:

18.7 units

Step-by-step explanation:

In this right-angled triangle, you are provided with:

Two angles (i.e. 36° and 90°)

One side (i.e. Line AC, which is 11 units)

Line AB is known as the 'hypotenuse' of the right-angled triangle, which is what needs to be determined.

On the basis of 36° angle:

The side opposite (i.e. Line AC)  is known as the 'opposite' or 'perpendicular side'

The side adjacent (i.e. Line BC) is known as the 'adjacent' or 'base'

Trigonometric function:

The trigonometric function, which connects an angle, it's opposite side and the hypotenuse is the 'sine function':

sinФ = [tex]\frac{opposite}{hypotenuse}[/tex]

sin36° = [tex]\frac{11}{x}[/tex]

Cross-multiplication is applied:

x needs to be isolated and made the subject of the equation:

xsin36° = 11

≡ x = [tex]\frac{11}{sin36^{o}}[/tex]

∴ x = 18.7 units (Rounded off to 3 significant figures)

A. The linear relationship can be expressed by the equation, 3y = 5x + 10

B. For  25 kg, the height is 45 cm

   For  52 kg, the height is 90 cm

C. For 60 cm, the mass is 34

    For 80 cm, the mass is 46

The equation of a straight line is a relationship between x and y coordinates, The two point form of the equation of a straight line is,

y-y₁ =  (y₂-y₁)/(x₂-x₁)*(x-x₁)

Given that,

The scatter plot,

which shows the linear relationship,

And passes through the points,

(10, 20), (40, 70)

the equation of line can be written as,

y - 20 =  (70-20)/(40-10)*(x-10)

y - 20 = 50/30*(x-10)

y - 20 = 5/3*(x-10)

3y - 60 = 5x - 50

3y = 5x + 10

A. The linear relationship,
3y = 5x + 10

B.    If x = 25, we can substitute this value into the equation to find the corresponding value of y:

3y = 5 x 25 + 10

3y = 125 + 10

3y = 135

Dividing both sides of the equation by 3:

y = 45

So, if x = 25, then y = 45.

similarly,  the value of y for x = 25 is, 90

In the same manner,

when,

For y = 60 x will be 34

And for y = 80 x will be 46

Her average speed for the entire trip, in kilometers per hour, is equal to 2d / (7.1 * 3600) * 3600 km/h

Let's assume that the total distance of the round trip is d kilometers and that she drove at a constant speed of v km/h for the entire trip. The time it takes for her to travel the entire distance at speed v is given by t = d/v.

Since she drove back home using the same path she took out to the university, her average speed for the entire trip must be equal to her speed on the way out and back. Therefore, the total time it took for her to complete the round trip is 2t = 2d/v.

Since the total time it took for her to complete the round trip is 7.1 hours, we can set up an equation:

2d/v = 7.1 hours

Converting hours to seconds and solving for v, we have:

v = 2d / (7.1 * 3600) km/s

Finally, converting to km/h, we get:

v = 2d / (7.1 * 3600) * 3600 km/h

Therefore, her average speed for the entire trip, in kilometers per hour, is equal to 2d / (7.1 * 3600) * 3600 km/h

b) The five-number summary of the sample is minimum = 4, Q1 = 4.5, median = 9 , Q3 = 15.5 and maximum= 16.

The population mean is denoted by greek letter, μ and sample mean is a random variable; which is written as x-bar and x-bar stands for individual values it takes. The sample mean is a statistic measure obtained by calculating the arithmetic mean of sample values ( values of variable in sample). The sample mean formula is: x-bar = ( Σxᵢ) / n

Now, we have to calculate sample mean of following data values, 12,8,15,16,5,4.

Sum of values, Σ xi = 12 + 8 + 15 + 5 + 4 + 16 = 60

Number of values = 6

So, Sample mean, = ( Σ xi ) / n = 60/6 = 10

The five-number summary includes following :

So, Steps to determine the five-number summary:

Now, the sample set is 12,8,15,16,5,4. Arrange the data values in ascending order, 4,5,6,12,15,16. So, Minimum value

So the total cost of tying the lace around the tablecloth is $18.36.

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. An example of an equation is 4 + 6 = 10.

Here,

The length of the boundary of the square table cloth is 4 times its side length, so the length of the boundary is 4 * 54 cm = 216 cm.

To convert the length from centimeters to meters, we divide by 100:

216 cm / 100 = 2.16 meters

Finally, to find the cost of sticking the lace around the table cloth, we multiply the length of the lace by the cost per meter:

The best way is to use the Ratio Test to see that the series = ∑∞ₙ₋₁ n/5ⁿ converges.

In mathematics, convergence definition is the property (some described by myriad series and functions) that it approaches its limit more and more distinctly as the arguments (variables) of the function increase or decrease, or as the number of terms in the series increases.

For example, the function y = 1/x converges to zero as x increases. Even in this case, the final value of x doesn't affect the value of y to actually be zero, and the marginal value of y is zero, since y can be made arbitrarily small by choosing a large enough "x". The line y = 0 (x-axis) is known as the asymptote of the function.

According to the Question:

Let aₙ= n/5ⁿ. If  lim(n→∞)

|an+1|/ |an| <1, the Ratio Test will imply that  

∑∞ₙ₋₁ aₙ = ∑∞ₙ₋₁ n/5ⁿ converges.

Now,

aₙ₊₁ = n + 1/ 5ⁿ⁺¹

    = n + 1 /5.5ⁿ.

Therefore,

since these terms are positive,

    |aₙ₊₁|/|aₙ| = n + 1 /5⋅5ⁿ

⇒ n +1/ 5ⁿ → 1/5 as n→∞

Hence,

∑∞ₙ aₙ = ∑∞ₙ₋₁ n/5ⁿ converges.

 One of the properties of a mirror reflection is that the angle of incidence i.e. the angle at which light strikes the mirror = angle of reflection i.e. the angle at which the light reflects off the mirror

These angles are shown as α and β in the diagram

The two triangles we choose to solve this problem are
ΔABC and ΔCED

Given that ∠BCA is a complementary angle to angle of reflection and ∠ECD is complementary to the angle of incidence, it follows that

m∠BCA = m∠CED

m∠BAC of ΔABC = m∠ECD of ΔECD = 90°

Therefore the third angles of both triangles are also equal

b) By the AA (or AAA) or Angle-Angle Similarity theorem, the two triangles are similar

Therefore the ratio of the sides must be the same for corresponding sides

The cylinder serves to randomly distribute the bullet among the chambers, so if the cylinder is not spun, the bullet will remain in the same chamber, and the outcome of the second try will be determined by the initial placement of the bullet in the cylinder.

In a typical scenario where a revolver with a single bullet is used, the probability of survival on the first try is 1/6, and the probability of survival on the second try (assuming the cylinder is spun) is also 1/6.

The minimum number of rotations required for a 3500 km race is 52,800 rotations.

This is calculated by dividing the total distance of the race, 3500 km, by the circumference of the wheel, which is 2πr, where r is the radius of the wheel. The radius of the wheel must be between 27.5 cm (half of 55 cm) and 37.5 cm (half of 75 cm). So, the minimum number of rotations is given by 3500/(23.14r), where r is the minimum radius of the wheel. Substituting in r = 27.5 cm, we get the minimum number of rotations required for a 3500 km race as 52,800.

To arrive at this result, we must first calculate the circumference of the wheel, which is given by 2πr, where r is the radius of the wheel. Since the diameter of the wheel must be between 55 cm and 75 cm, the radius of the wheel must be between 27.5 cm (half of 55 cm) and 37.5 cm (half of 75 cm).

We then divide the total distance of the race, 3500 km, by the circumference of the wheel, which is given by 2πr. Substituting in the minimum radius of the wheel, 27.5 cm, we get the minimum number of rotations required for a 3500 km race as 52,800.
