What is inverse notation?
Hitman42 [59]

In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, f(x) = y if and only if g(y) = x.

PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!!

The length of PR is 4.4 units.

Explanation:

It is given that the length of the hypotenuse is 10 units.

Also, the angle of R is 64°

To find the length of PR, we shall use the cosine formula,

\cos \theta=\frac{a d j}{h y p}

Here,  \theta=64, adj = PR and hyp = 10

Substituting these values in the formula, we get,

\cos 64=\frac{P R}{10}

Multiplying both sides by 10, we get,

10*\cos 64={P R}

Substituting the value for cos 64, we get,

10*0.438={P R}

Multiplying, we have,

4.38=PR

Rounding off, we get,

PR=4.4

Thus, the length of PR is 4.4 units.

- x - x + 11 - 2x = 83<br>please show step by step!!​
m_a_m_a [10]

Answer:

x=-18

Step-by-step explanation:

<u>Given</u>

<u />-x-x+11-2x=83

<u>Step 1: Combine Like Terms on LHS</u>

<u />-x-x+11-2x=83\\-2x+11-2x=83\\-4x+11=83

<u>Step 2: Subtract 11 on both sides</u>

<u />-4x+11=83\\-4x+11-11=83-11\\-4x=72

<u>Step 3: Divide both sides by -4 to isolate the x-variable</u>

<u />-4x=72\\\\\frac{-4x}{-4}=\frac{72}{-4}\\ \\ x=-18

<u>Final Answer</u>

<u />x=-18
