[(8*9)] - (6*7)] -15
maks197457 [2]

Answer:

15

Step-by-step explanation:

Simplify the following:

8×9 - 6×7 - 15

8×9 = 72:

72 - 6×7 - 15

-6×7 = -42:

72 + -42 - 15

72 - 42 - 15 = 72 - (42 + 15):

72 - (42 + 15)

| 4 | 2

+ | 1 | 5

| 5 | 7:

72 - 57

| 6 | 12

| 7 | 2

- | 5 | 7

| 1 | 5:

What is the trigonometric ratio for cosn? enter your answer, as a simplified fraction, in the boxes. $$ triangle l m n with righ
hjlf

The trigonometric ratio will be Cos(n)=12/13

<h3>What will be the trigonometry ratio?</h3>

Given is a Right triangle LMN with right angle at M i.e. angle M = 90 degrees.

Given are the sides LM = 15, MN = 36, and LN = 39.

It says to find cos(n) = ?

So opposite side would be LM, adjacent side would be MN, and LN is the hypotenuse.

We know that the cosine ratio is given by :-

Cos(n)=\dfrac{adjacent}{Hypotenuse}

Cos(n)=\dfrac{MN}{LN}

Cos(n)=\dfrac{36}{39}

Cos(n)=\dfrac{12}{13}

Hence the required ratio will be   Cos(n)=\dfrac{12}{13}

Steps to finding the line in the diagram with the format 'ax + by = c

1. Find the slope

  • To find the slope, we need any two points on the line --> (0,4) and (3,0)

                  Slope = \frac{y2-y1}{x2-x1} =\frac{4-0}{0-3} =-\frac{4}{3}

2. Set up, with any one point on the line and the slope, in point-slope form

   

        (y-y0)=m(x-x0)\\(y-4)=-\frac{4}{3} (x-0)\\y-4 = -\frac{4}{3} x\\\frac{4}{3}x+y = 4

<u>Answer</u>: \frac{4}{3}x+y = 4

Hope that helps!
