Answer:

The answer to your question is below

Step-by-step explanation:

Use trigonometric functions to find x

13. cos 40 = 5/x

x = 5 / cos 40

x = 5 / 0.766

x = 6.5

14. tan 25 = x/9

x = 9tan 25

x = 9(0.466)

x = 4.2

15.- cos 65 = x/12

x = 12 cos 65

x = 12 (0.423)

x = 5.1

16.- sin 32 = 15/x

x = 15 / sin 32

x = 15 / 0.53

x = 28.3

17.- tan 55 = 20 / x

x = 20 / tan 55

x = 20 / 1.42

x = 14

18.- sin31 = x / 18

x = 18 sin 31

x = 18 (0.52)

x = 9.3

Find the value of the variable y, where the sum of the fractions 6/(y+1) and y/(y-2) is equal to their product.

Blizzard [7]

Answer:

The answer is

$y = 3$

$y = - 4$

Step-by-step explanation:

We must find a solution where

$\frac{6}{y + 1} + \frac{y}{y - 2} = \frac{6}{y + 1} \times \frac{y}{y - 2}$

Consider the Left Side:

First, to add fraction multiply each fraction on the left by it corresponding denomiator and we should get

$\frac{6}{y + 1} \times \frac{y - 2}{y - 2} + \frac{y}{y - 2} \times \frac{y + 1}{y + 1}$

Which equals

$\frac{6y - 12}{(y -2) (y + 1)} + \frac{ {y}^{2} + y }{(y - 2)(y + 1)}$

Add the fractions

$\frac{y {}^{2} + 7y - 12 }{(y - 2)(y + 1)} = \frac{6}{y + 1} \times \frac{y}{y - 2}$

Simplify the right side by multiplying the fraction

$\frac{6y}{(y + 1)(y + 2)}$

Set both fractions equal to each other

$\frac{6y}{(y + 1)(y - 2)} = \frac{ {y}^{2} + 7y - 12}{(y + 1)(y - 2)}$

Since the denomiator are equal, we must set the numerator equal to each other

$6y = {y}^{2} + 7y - 12$

$= {y}^{2} + y - 12$

$(y + 4)(y - 3)$

$y = - 4$

$y = 3$

elena55 [62]

Answer: Since you didn't include the picture, I can give you the description so you know how to pick the correct answer.

The third quartile of a data is always shown in a box plot. In the middle of your graph should be a box. The third quartile is the value that goes with the far right edge of the box.
