Answer:

The answer is 12

Step-by-step explanation:

First, you do 2+8=10. You do that first becuase it is in the parentheses

After that, You do 15+3=18

Then, 4 and the 2 over it. Which is a exponent. And that tells you to multiple the number by itself. So 4x4=16.

But it also says subtract the 4. So now you Add the 10+18=28

Then you subtract 16 from 28. 28-16=12.

Thats how you get your answer.

The correct answer is 28.3.

You take 22/1.4 and get 15.7142857143. Then you take 15.7142857143*1.8 which equals 28.2857142857 so you round it up to 28.3 which is the answer.

I hope this helps you:)

The point (1/3,1/4) lies on the terminal said of an angle. Find the exact value of the six trig functions and explain which func

Answer:

sine and cosec are inverse of each other.

cosine and sec are inverse of each other.

tan and cot are inverse of each other.

Step-by-step explanation:

Given point on terminal side of an angle ( $\frac{1}{3},\frac{1}4$ ).

Kindly refer to the attached image for the diagram of the given point.

Let it be point A( $\frac{1}{3},\frac{1}4$ )

Let O be the origin i.e. (0,0)

Point B will be ( $\frac{1}{3},0$ )

Now, let us consider the right angled triangle $\triangle OBA$ :

Sides:

$Base, OB = \frac{1}{3}\\Perpendicular, AB = \frac{1}{4}$

Using Pythagorean theorem:

$\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow OA^{2} = OB^{2} + AB^{2}\\\Rightarrow OA^{2} = \frac{1}{3}^{2} + \frac{1}{4}^{2}\\\Rightarrow OA = \sqrt{\frac{1}{3}^{2} + \frac{1}{4}^{2}}\\\Rightarrow OA = \sqrt{\frac{4^2+3^2}{3^{2}.4^2 }}\\\Rightarrow OA = \frac{5}{12}$
