By ASA property

Therefore, if all three sides of two triangles are the same, then the triangles are said to be congruent. If we have a side, an angle between the sides, and then another side that is congruent, we know they are congruent. In other words, side, angle, side.

We are asked that will property will show that Δ NKL ≅Δ LMN

It is given that NL  bisect KNM and KLM

∠ KNL≅ ∠ MNL (by bisect property)  (angle)

∠ KLN ≅∠MNL (by bisect property)    (angle)

line NL   (common)

Thus by ASA property we can say that Δ NKL ≅ΔLMN

What are double angles in trigonometry?

The double angle formulas are used to find the values of double angles of trigonometric functions using their single angle values. For example, the value of cos 30° can be used to find the value of cos 60°. Also, the double-angle formulas can be used to derive the triple-angle formulas.

Given: tanx = -3

Now as we know,

                  [tex]sin2x=\frac{2tanx}{1+tan^2x}\\\\sin2x=\frac{2(-3)}{1+(-3)^2}\\\\sin2x=\frac{-6}{10}\\\\sin2x=\frac{-3}{5}[/tex]

Now

               [tex]cos2x=\frac{1-tan^2x}{1+tan^2x}\\\\cos2x=\frac{1-(-3)^2}{1+(-3)^2}\\\\cos2x=\frac{1-9}{1+9}\\\\cos2x=\frac{-8}{10}\\\\cos2x=\frac{-4}{5}[/tex]

And similarly, we can find the value of tan2x, as

                  tan2x = sin2x/cos2x

                             = (-3/5)/(-4/5)

                             = 3/4

Hence,

The values would be

sin2x = -3/5

cos2x = -4/5

tan2x = 3/4

Answer: five beers' worth of alcohol in a bottle of wine.

Step-by-step explanation:

In order to have an equivalent amount of alcohol as red wine, we would need to consume approximately 6 bottles of beer.

To determine how many bottles of beer need to be consumed in order to have an equivalent amount of alcohol as red wine, we can compare the alcohol content in both beverages.

The red wine has a volume of 750 ml and an alcohol content of 12%. This means that the red wine contains 750 ml x (12/100) = 90 ml of alcohol.

The beer has a volume of 330 ml and an alcohol content of 5%. This means that each bottle of beer contains 330 ml x (5/100) = 16.5 ml of alcohol.

To find the number of beer bottles needed to match the alcohol content of the red wine, we divide the total amount of alcohol in the red wine by the amount of alcohol in one beer bottle:

The number of beer bottles:

90 ml / 16.5 ml = 5.45

Since we can't have a fraction of a beer bottle, we round up to the nearest whole number.

3-year treasury securities as calculated from the data will now have a rate of 3.70%.

Current interest rate is calculated as Current Interest Rate + Liquidity Premium.

Average interest for 3 Year = (3.45% + 3.95% +3.25%)/3   = 3.55

3 year security liquidity premium = 0.15%

3 year Treasury security's current rate is 3.55% +0.15%.

= 3.70%

Therefore, The current rate be on 3-year treasury securities is 3.70%.

Interest is the fee paid for having access to borrowed funds. While the interest rate used to compute interest is often reported as an annual percentage rate, interest expense or revenue is sometimes expressed as a dollar figure (APR).

The total number of pairs sold by SoccerWorld is 57

From the question, we have the following parameters that can be used in our computation:

The above parameters means that

s = 3j

d = 5 + j

70(s + d + j) = 7000

Where

j = JP Sports

s = SoccerWorld

d = DirectSportz

Divide both sides of 70(s + d + j) = 7000 by 70

s + d + j = 100

Substitute s = 3j and d = 5 + j

3j + 5 + j + j = 100

Evaluate the like terms

5j = 95

Divide by 5

j = 19

Substitute j = 19 in s = 3j

s = 3 * 19

So, we have

The equation Vy = a sin(k(x - d)) + c is an equation for a sine wave. A sine wave is a periodic function that describes a periodic oscillation or vibration. It is commonly used to model periodic phenomena in many fields, such as sound, light, and electricity.

In this equation, Vy is the vertical position of the sine wave at a given point in time (x), a is the amplitude of the sine wave (the maximum distance from the midline), k is the wave number (the number of complete cycles per unit distance), x is the horizontal position (time or distance), d is the phase shift (the horizontal shift of the wave), and c is the vertical offset (the distance from the midline).

The equation y = a cos(k(x - d)) + c is similar to the equation for a sine wave, but it describes a cosine wave instead. A cosine wave is also a periodic function, but it is shifted by 90 degrees in phase compared to a sine wave.

Like a sine wave, a cosine wave can be used to model periodic phenomena and is commonly used in many fields.

The values of a, h and k for the  given quadratic function are:

a = -6, h = -5 and k = -1

What is vertex form?

This is one way of writing a quadratic function:

f(x) = a(x-h)² +k

(h, k) = vertex

a = vertical stretch

According to the given question:

We're given:

f(x)= -6x² - 60x - 151

To write a quadratic function in vertex form, we must complete the square.

⇒ Put parentheses around the first two terms containing x and x²:

f(x)= (-6x² - 60x) - 151

⇒ Factor out -6 (keeping the x's in the parentheses):

f(x)= -6(x² + 10x) - 151

⇒ To complete the square, add, inside the parentheses, the square of half the coefficient of x.

⇒ In this case, the coefficient of x is 10.

⇒ Half of this value is 5.

⇒ The square of 5 is 25.

⇒ Add this inside the parentheses:

f(x) =  -6(x² + 10x + 25) - 151

⇒ Now, we cannot randomly introduce a new value into a function. To balance the +25, subtract -6(25) outside the parentheses:

f(x) =  -6(x² + 10x + 25) - 151 - (-6 x 25)

f(x) =  -6(x² + 10x + 25) - 151 - (-150)

f(x) =  -6(x² + 10x + 25) - 151 + 150

f(x) =  -6(x² + 10x + 25) - 1

⇒ Finally, complete the square.

Remember: (a + b)² = a² + 2ab + b²

In this case, a is x, and b is 5:

f(x) = -6(x + 5)² - 1

On comparing with f(x) = a(x-h)² +k we get the values of a, h and k as:

a = -6

h = -5

k = -1

The new mean for the given data would be 80.

What is the mean of the numbers?

The average (mean) is equal to the sum of all the data values divided by the number of values in the data set.

Mean = Sum / Count

Firstly 18 students took the test and the mean was 81.

By using the definition of mean we can write

        Mean = sum of scores/number of students

         81 = sum of scores / 18

    Sum of scores = 81 * 18

                             = 1458

Now later the four absent kids made it up and scored 77, 85, 68, and 80.

Now new sum of the scores would be = 1458 + 77 +  85 + 68 + 80

                                                               = 1768

And the total number of students will be = 18 + 4 = 22

New mean = new score/number of students

                  = 1768/22

What are the trigonometric angles?

Trigonometry angles are the angles given by the ratios of the trigonometric functions. Trigonometry deals with the study of the relationship between angles and the sides of a triangle. The angle value ranges from 0-360 degrees. The important angles in trigonometry are 0°, 30°, 45°, 60°, 90°, 180°, 270° and 360°.

sin B = 3/5

tan A = 5/12

We have find cos(A - B)

first, let’s hope these are both all-integer triangles:

In a 3-4-5 Right triangle,

sinB = 3/5, cos B = 4/5

For tanA = 5/12 the hypotenuse turned out to be 13.

sin A = 5/12

cos A = 12/13

So now we just use the identity for cos ( A +  B )

cos(A - B) = cosAcosB + sinAsinB

                = (12/13)(4/5) + (5/12)(3/5)

                = (60 + 52/65) + (25 + 36/60)

                = (112/65) + (61/60)

The biweekly pay is $1,385, the hourly rate of pay for 160 hours of work per month is $17.31, and the overtime rate of pay is $25.96.

It is given that, the annual pay is $36,010.

There are 52 weeks in a year. So, there are 26 biweeks in a year.

Then, the biweekly pay = (Annual pay)/the number of biweeks in a year

⇒ biweekly pay = (36,010)/26 = $1,385

There are 160 working hours in a month.

So, biweekly working hours = 160/2 = 80 (for two weeks in a month)

Then, the hourly rate of pay is calculated by

hourly rate of pay = biweekly pay/biweekly working hours

⇒ hourly rate of pay = 1,385/80 = $17.31

To calculate the overtime rate of pay, we need to know the number of overtime working hours and the multiplier.

Here we are finding the overtime rate per hour. So, we can find the overtime rate of pay by

overtime rate of pay = hourly rate of pay × multiplier
