Answer:

<h2>The result is \frac{27}{2}</h2>

Step-by-step explanation:

We have to resolve:

<h2>[\frac{13}{50} +\frac{(-11)}{70}]:[\frac{(-16)}{35} .\frac{1}{(-60)} ]</h2>

First we are going to analyze by separate:

<h2>[\frac{13}{50} +\frac{(-11)}{70}]</h2>

We have to look for the least common denominator between 50 and 70, which is 350, then we have to rewrite:

<h2>[\frac{13}{50} +\frac{(-11)}{70}]=[\frac{91}{350}+ \frac{(-55)}{350} ]\\\\=[\frac{91-55}{350} ]\\\\=[\frac{36}{350}]</h2>

We can simplify dividing in 2:

<h2> \frac{36}{350} =\frac{18}{175}</h2>

Now we have to look the other part:

<h2>[\frac{(-16)}{35} .\frac{1}{(-60)} ]</h2>

This is a multiplication so we have to cross-simplify:

We can't simplify 35 and 1 but we can simplify (-16) and (-60) in 4:

<h2>[\frac{(-16)}{35} .\frac{1}{(-60)} ]=[\frac{4}{35} .\frac{1}{15} ]\\\\=[\frac{4}{525}]</h2>

Now uniting what we analyzed separately:

<h2>\frac{18}{175}:\frac{4}{525}</h2>

We can simplify, we have a division then we have to simplify numerator with numerator and  denominator with denominator.

We are going to simplify the numerators in 2 and the denominators in 175:

<h2>\frac{18}{175}:\frac{4}{525}=\frac{9}{1} :\frac{2}{3}=\frac{27}{2}</h2><h2>Then the result is \frac{27}{2}</h2>

If 2tanA=3tanB then prove that,<br>tan(A+B)= 5sin2B/5cos2B-1​
Fed [463]

By definition of tangent,

tan(A + B) = sin(A + B) / cos(A + B)

Using the angle sum identities for sine and cosine,

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

cos(x + y) = cos(x) cos(y) - sin(x) sin(y)

yields

tan(A + B) = (sin(A) cos(B) + cos(A) sin(B)) / (cos(A) cos(B) - sin(A) sin(B))

Multiplying the right side by 1/(cos(A) cos(B)) uniformly gives

tan(A + B) = (tan(A) + tan(B)) / (1 - tan(A) tan(B))

Since 2 tan(A) = 3 tan(B), it follows that

tan(A + B) = (3/2 tan(B) + tan(B)) / (1 - 3/2 tan²(B))

… = 5 tan(B) / (2 - 3 tan²(B))

Putting everything back in terms of sin and cos gives

tan(A + B) = (5 sin(B)/cos(B)) / (2 - 3 sin²(B)/cos²(B))

Multiplying uniformly by cos²(B) gives

tan(A + B) = 5 sin(B) cos(B) / (2 cos²(B) - 3 sin²(B))

Recall the double angle identities for sin and cos:

sin(2x) = 2 sin(x) cos(x)

cos(2x) = cos²(x) - sin²(x)

and multiplying uniformly by 2, we find that

tan(A + B) = 10 sin(B) cos(B) / (4 cos²(B) - 6 sin²(B))

… = 10 sin(B) cos(B) / (4 (cos²(B) - sin²(B)) - 2 sin²(B))

… = 5 sin(2B) / (4 cos(2B) - 2 sin²(B))

The Pythagorean identity,

cos²(x) + sin²(x) = 1

lets us rewrite the double angle identity for cos as

cos(2x) = 1 - 2 sin²(x)

so it follows that

tan(A + B) = 5 sin(2B) / (4 cos(2B) + 1 - 2 sin²(B) - 1)

… = 5 sin(2B) / (4 cos(2B) + cos(2B) - 1)

… = 5 sin(2B) / (4 cos(2B) - 1)

as required.

What is the area of a rectangle if 1 base is 14 in, the 2nd base is 3.5 in and the height is 8 in?​
algol13

Check the picture below.

notice, we have three pair of sides, let's add them all up to get the area

\stackrel{\textit{left and right}}{2(8\cdot 14)}+\stackrel{\textit{front and back}}{2(3.5\cdot 8)}+\stackrel{\textit{top and bottom}}{2(3.5\cdot 14)}\implies 378~in^2
