Examine the following steps. Which do you think you might use to prove the identity Tangent (x) = StartFraction tangent (x) + ta
Over [174]

Answer:

The correct options are;

1) Write tan(x + y) as sin(x + y) over cos(x + y)

2) Use the sum identity for sine to rewrite the numerator

3) Use the sum identity for cosine to rewrite the denominator

4) Divide both the numerator and denominator by cos(x)·cos(y)

5) Simplify fractions by dividing out common factors or using the tangent quotient identity

Step-by-step explanation:

Given that the required identity is Tangent (x + y) = (tangent (x) + tangent (y))/(1 - tangent(x) × tangent (y)), we have;

tan(x + y) = sin(x + y)/(cos(x + y))

sin(x + y)/(cos(x + y)) = (Sin(x)·cos(y) + cos(x)·sin(y))/(cos(x)·cos(y) - sin(x)·sin(y))

(Sin(x)·cos(y) + cos(x)·sin(y))/(cos(x)·cos(y) - sin(x)·sin(y)) = (Sin(x)·cos(y) + cos(x)·sin(y))/(cos(x)·cos(y))/(cos(x)·cos(y) - sin(x)·sin(y))/(cos(x)·cos(y))

(Sin(x)·cos(y) + cos(x)·sin(y))/(cos(x)·cos(y))/(cos(x)·cos(y) - sin(x)·sin(y))/(cos(x)·cos(y)) = (tan(x) + tan(y))(1 - tan(x)·tan(y)

∴ tan(x + y) = (tan(x) + tan(y))(1 - tan(x)·tan(y)

I need help please i​
balandron [24]

Answer:

<em>2 7/24</em>

Step-by-step explanation:

<em>First we have to add the gallons of two cow of each owner:</em>

<em>Hank's cows: </em><em>4 3/4 + 4 1/8</em>

<em>Add the whole numbers:</em>

<em>4 + 4 = 8</em>

<em>Now for 3/4 and 1/8 </em>

<em>Find common</em>

<em>6/8 + 1/8</em>

<em>= 7/8</em>

<em>Put together :</em>

<em>8 7/8</em>

<em>Debra's cows: </em><em>5 1/2 + 5 2/3</em>

<em>Add the whole number</em>

<em>5 + 5 = 10</em>

<em>Now for 1/2 and 2/3</em>

<em>3/6 + 4/6</em>

<em>1 1/6</em>

<em>10 + 1 1/6 </em>

<em>= 11 1/6</em>

<u><em>Since now we know that:</em></u>

<u><em>Hank - </em></u><em>8 7/8</em>

<u><em>Debra - </em></u><em>11 1/6</em>

<em>we can solve the question:</em>

<em>How many more gallons of milk did Debra's two cows produce on that compared to Hank's two cows?</em>

<em>Solution:</em>

<em>11 1/6 - 8 7/8</em>

<em>Subtract whole number</em>

<em>11 - 8 = 3</em>

<em>Now for 1/6 and 7/8</em>

<em>4/24 - 21/24</em>

<em>4-21/24</em>

<em>-17/24</em>

<em>2 7/24</em>
