What is Trigonometric Functions?

Trigonometry uses six fundamental trigonometric operations. Trigonometric ratios describe these operations. The sine function, cosine function, secant function, co-secant function, tangent function, and co-tangent function are the six fundamental trigonometric functions. The ratio of sides of a right-angled triangle is the basis for trigonometric functions and identities. Using trigonometric formulas, the sine, cosine, tangent, secant, and cotangent values are calculated for the perpendicular side, hypotenuse, and base of a right triangle.

The Law of Sines (or Sine Rule) is very useful for solving triangles:

[tex]\frac{a}{sinA} = \frac{b}{sinB} + \frac{c}{sinC}[/tex]

840 / sin(38) = g /sin(49)

g = (840 / sin(38) ) *sin(49)

g= (840/0.615) *0.754 = 1029.8

Cynthia is participating in the Spartan Super, a 10-mile obstacle course.  She completes 4 miles of the obstacle course every hour.

Cynthia’s distance from this finish line, y, after x hours is represented by the function 4x + y = 10.

Therefore, the y-intercept is the point where a graph crosses the y-axis. In other words, it is the value of y when x = 0.

The x-intercept is where a line crosses the x-axis. The x-intercept is the value of x when y = 0.

Linear function in slope intercept form is as follows:

y = mx + b

where

Hence,

4x + y = 10

y = -4x + 10

Hence, y-intercept is 10.

y = -4x + 10

Let's find x-intercept

0 = -4x + 10

-10 = -4x

x = 10 / 4

To test the claim that meal preference and gender are not related, you can use a chi-squared test for independence.

The null hypothesis for this test is that there is no relationship between the variables, while the alternative hypothesis is that there is a relationship. To conduct the test, you will need to calculate the chi-squared statistic and compare it to the critical value from a chi-squared distribution with one degree of freedom. The degrees of freedom for this test are calculated as (number of rows - 1) * (number of columns - 1), which in this case is (2-1)*(2-1) = 1.

To calculate the chi-squared statistic, you will need to compare the observed frequencies in the table to the expected frequencies if the null hypothesis were true. The expected frequency for each cell is calculated as the row total * column total / sample size.

For example, the expected frequency for females who prefer hamburgers is (39 * 15)/59 = 12.71. The chi-squared statistic is then calculated as the sum of the squared differences between the observed and expected frequencies, divided by the expected frequencies. In this case, the chi-squared statistic would be:

((15-12.71)^2/12.71) + ((23-26.29)^2/26.29) + ((24-26.29)^2/26.29) + ((16-12.71)^2/12.71) = 7.39

To determine whether this result is statistically significant, you would compare the chi-squared statistic to the critical value from a chi-squared distribution with one degree of freedom. At a significance level of 0.05, the critical value is 3.84. Since the chi-squared statistic (7.39) is greater than the critical value (3.84), you can reject the null hypothesis and conclude that there is a relationship between meal preference and gender in this sample.

6 7/12

Step-by-step explanation:

"12 1/4 - 5 2/3" is an expression.  It is not said to equal anything.  The "=" sign makes it an equation.  But we can evalute an expression by simplyfying it.  Let's do the subtraction.  We first need to convert one of the fractions so that it has the same denominator as the other.

12 1/4 - 5 2/3 can be written as (12 - 5)+(1/4 - 2/3)

(12 - 5)+(1/4 - 2/3)

(7)+(1/4 - 2/3)        Let's convert both fractions to have denominators of 12 [since 4*3 = 12]

7 + 1/4 - 2/3

7 + (1/4)*(3/3) - (2/3)*(4/4)   [Multiply the tqo fractions by (3/3) and (4/4), repectively.  This is OK since both are the equivalent of multiply by 1.  But it converts the denominators so that we can now add or subtract.

B. ​No, the congruent angles are not the included angles.

Step-by-step explanation:

The SAS (Side-Angle-Side) Postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.

In the given figure, we can see that two sides of the two triangles are congruent: side AB is congruent to side DE, and side AC is congruent to side DF. However, the included angles, which are the angles formed by these sides, are not congruent. Angle BAC is not congruent to angle EDF.

Since the included angles are not congruent, we cannot use the SAS Postulate to conclude that the two triangles are congruent. Therefore, the correct answer is B: No, the congruent angles are not the included angles.

Answer:

  B.  ​No, the congruent angles are not the included angles.

The company's cost of preferred stock is 9.08%, which means the correct answer is B) 9.08%. The cost of a service may be determined by the amount of time and expertise required to provide it. In general, cost is an important factor in determining the feasibility and profitability of a project or business venture.

Cost refers to the amount of money that is required to purchase or produce something. For example, the cost of a product may be determined by the amount of materials and labor that went into producing it, as well as any other expenses associated with bringing it to market.

To calculate the company's cost of preferred stock, we need to use the following formula:

Cost of preferred stock = annual dividend / price per share - flotation cost

In this case, the annual dividend is $8.50, the price per share is $97.50, and the flotation cost is 4.00% of the price paid by investors. Plugging these values into the formula, we get:

Cost of preferred stock = $8.50 / $97.50 - 4.00% = $8.50 / $97.50 * (1 - 0.04) = $8.50 / $93.80 = 0.0908

You want to know the congruence theorem that lets you say ∆ACD≅∆CAB, given that AB=CD and AB║CD.

The triangles are congruent if an angle or side can be shown congruent, in addition to at least one angle and at least one side.

Here, the sides AB and CD are shown congruent. The side AC is congruent to itself, so we only need the angle(s) between them to show the triangles are congruent.

The Alternate Interior Angles theorem tells you that transversal AC creates congruent angles CAB and ACD with respect to the parallel lines AB and CD.

Hence we can show triangle ACD and CAB are congruent by the SAS congruence theorem.

Yes, The triangle is congruent by Angle - Side - Angle  congruence theorem.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

⇒ AB || CD

Now,

In figure,

⇒ AB || CD

So, In triangle ACD and triangle CAB;

⇒ AB || CD

So, By definition of alternate angles,

⇒ ∠ BAC = ∠ DCA

And, ∠ DAC = ∠ ACB

What is  standard deviation?

Your dataset's average level of variability is represented by the standard deviation. In general, it reveals how far away from the mean each value is.

Let X~ Normal (26, 4/√16) distribution ie Normal (26, 1) distribution

We want,

P(X<a) = 0.82

Using standard normal approximation,

P(z< (a-26)/1) = 0.82

Using standard normal distribution tables, we get

(a-26)/1 = 0.915

2. If x∉S, then x∈g(x)=S, i.e., x∈S, a contradiction.

Given that,

In the same time it took to row 25 miles against the current, a rowing team was able to row 50 miles while travelling with it. 2 miles per hour was the current's speed.

We have to calculate the rowing team's speed in still water.

We know that,

Let rowing rate in still water = r

And current rate = c = 2 mph

Rowing with the current means the overall speed is r + c = r + 2

Rowing against the current means the overall speed is r - c = r - 2

Distance = Rate × Time

50 = (r+2) × t  ----->equation(1)  

25 = (r-2) × t  ----->equation(2)

By solving

Divide equation(1) by equation(2)

50/25 = (r+2) × t / (r-2) × t

2=r+2/r-2

2(r-2)=r+2

2r-4=r+2

2r-r=2+4

r=6mph

Substitute in equation(1)

50 = (r+2) × t

50=(6+2)×t

50=8t

t=50/8

t=6.25 hrs

y = [tex]\frac{5}{4}[/tex] x - 1 ← is in slope- intercept form

with slope m = [tex]\frac{5}{4}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{5}{4} }[/tex] = - [tex]\frac{4}{5}[/tex] , then

y = - [tex]\frac{4}{5}[/tex] x + c ← is the partial equation of the perpendicular line
