What is the algorithm for the inverse of f (x)?<br>​
Juli2301 [7.4K]

Answer:

What is an inverse?

Recall that a number multiplied by its inverse equals 1. From basic arithmetic we know that:

The inverse of a number A is 1/A since A * 1/A = 1 (e.g. the inverse of 5 is 1/5)

All real numbers other than 0 have an inverse

Multiplying a number by the inverse of A is equivalent to dividing by A (e.g. 10/5 is the same as 10* 1/5)

What is a modular inverse?

In modular arithmetic we do not have a division operation. However, we do have modular inverses.

The modular inverse of A (mod C) is A^-1

(A * A^-1) ≡ 1 (mod C) or equivalently (A * A^-1) mod C = 1

Only the numbers coprime to C (numbers that share no prime factors with C) have a modular inverse (mod C)

Step-by-step explanation:

Need Help Fast!!!!<br> Will Mark Brainlist!!!!<br> Will Rate!!!!<br> 9th Grade Honors Geometry
svetoff [14.1K]

Answer:

The Correct Answer is 4!

Step-by-step explanation:

We know on triangle 1 that 2 of the sides are 2 and 4 and there a right angle, an angle that has 90 degrees

with this we can calculate the top angle to be 26.565 which combined on both sides is equal to 90, lust you will then have to subtract 90 minus 26.565 and you will get 63.435. Now that we know than the top angle is equal to 63.435, the 2nd angle is equal to 90 degrees which by the way resembles a right angle, and that 1 side of the 3 sides is 2 we can conclude though the triangle formula that...

X=4.

That's it Hope I Helped.
