Trigonometric Identities

The basic trigonometric identity is:

[tex]\sin^2\theta+\cos^2\theta=1[/tex]

We'll use it and some basic algebra to prove that, given:

[tex]a sin^3\theta+b cos^3\theta=sin\theta cos\theta[/tex]

And

[tex]a\sin\theta-b\cos\theta=0[/tex]

Then

[tex]a^2+b^2=1[/tex]

From the equation:

[tex]a\sin\theta-b\cos\theta=0[/tex]

We have:

[tex]a\sin\theta=b\cos\theta\qquad [1][/tex]

The equation

[tex]a sin^3\theta+b cos^3\theta=sin\theta cos\theta[/tex]

Can be rewritten as

[tex]a\sin\theta \sin^2\theta+b \cos^3\theta=\sin\theta \cos\theta[/tex]

Replacing [1]:

[tex]b\cos\theta \sin^2\theta+b \cos^3\theta=\sin\theta \cos\theta[/tex]

Taking the common factor:

[tex]b\cos\theta (\sin^2\theta+ \cos^2\theta)=\sin\theta \cos\theta[/tex]

The expression in parentheses is 1, thus:

[tex]b\cos\theta =\sin\theta \cos\theta[/tex]

Dividing by [tex]\cos\theta[/tex]

[tex]b=\sin\theta[/tex]

Replacing in

[tex]a\sin\theta=b\cos\theta[/tex]

We have

[tex]a\sin\theta=\sin\theta\cos\theta[/tex]

Dividing by [tex]\sin\theta[/tex]

[tex]a=\cos\theta[/tex]

Now:

[tex]a^2+b^2=(\cos\theta)^2+(\sin\theta)^2[/tex]

This expression is 1, thus it's proven:

[tex]\boxed{a^2+b^2=1}[/tex]

Answer:

132 that's the answer...!!

Answer:

135 miles

Step-by-step explanation:

So first we have to find the difference of 83 and 100. So 100-83=27. So for miles, she can spend 27 dollars. Now, since per mile it costs 20 cents or 1/5 of a dollar, every time she drives 5 miles she'll have to pay one more dollar. So One dollar = 5 miles. Then we do the total amount of money she can spend on miles (27) and multiply that by the amount of miles per dollar (5) and we get 135 miles. So she can drive 135 miles.

Cindy ate 30 Skittles less than Ann and Ben together

-----> 7x = 5x + 5x - 30

-3x = -30

x = 10

5x = 50

========================================================

Explanation:

First solve for angle c

This angle adds to the 58 degree angle to get 180

c+58 = 180

c = 180-58

c = 122

This is congruent to angle f as well because alternate interior angles are congruent when we have parallel lines like this.

You could also solve 58+b = 180 to follow the same basic path as above. Corresponding angles are congruent when we have parallel lines.

Answer:

The probability is [tex]P(X | B) = 0.91[/tex]

Step-by-step explanation:

Generally the probability of the perpetrator being X  is equal  to the probability of the perpetrator being Y (given that both fugitives appear equally likely to be the perpetrator )

This can be mathematically represented as

         [tex]P(X) = P(Y) = \frac{1}{2}[/tex]

Let G represent the event that  the blood type of the sample is  type A

Generally if X has a blood type A then it is almost certain that the perpetrator is  X compared to Y

This can be mathematically represented as

        [tex]P(G | X) = 1[/tex]  

( Here this means  the probability of the sample being of type A given that the X has a blood type A )

Given that the sample belonging to Y  accidentally destroyed

   Then the probability that Y is innocent given that the blood type of  Y is of type  A

 This can be mathematically represented as

         [tex]P(G | Y) = 10\%[/tex]

         [tex]P(G | Y) = 0.10[/tex]

Generally according to  Bayes rule  the probability that person X is the perpetrator  mathematically as

         [tex]P(X | G) = \frac{P(G|X) * P(X)}{ P(G|X) * P(X) + P(G | Y ) * P(Y)}[/tex]

       [tex]P(X | B) = \frac{1 * 0.5 }{ 1 * 0.5 + 0.10 * 0.5}[/tex]

        [tex]P(X | B) = 0.91[/tex]

Answer:

First map, 1cm:10km

Distance between cleveland and cincinnati :

[tex]40 \times 10km = 400km[/tex]

Second map, 1cm: 50km

[tex] \frac{400km}{50km} = 8[/tex]

Therefore, the distance between the two places in second map will be 8 cm.

The distance between the two places on the second map will be 8 cm.

The ratio between a distance on a map and its corresponding distance on the ground is referred to as the "map scale." One kilometer on the ground is equal to one centimeter on a map with a scale of 1:100,000.

Given that the scale on the first map is 1 cm to 10 km. The distance from Cleveland to Cincinnati is 40 cm. The scale on the second map is 1 cm to 50 km.

The distance from Cleveland to Cincinnati on the second map will be calculated as below:-

40 X 10 = 400 KM

Second map, 1cm: 50km

( 400 / 50 ) = 8 cm

Therefore, the distance between the two places on the second map will be 8 cm.

Answer:

there are 2 variables: C is the dependent variable and r is the independent variable

Step-by-step explanation:

given

C = 2πr

we know that the value of 2π doesn't change (because π = 3.14.. and doesn't change) hence 2π is a constant value.

The only two items in the formula that could possibly change are

C and r

When the value of r changes, it will affect the value of C (i.e the value of C is dependent on the value of x)

Therefore there are 2 variables: C is the dependent variable and r is the independent variable.

Answer:

The answer is C
