Please help confused?Antonio is a freelance computer programer. In his work, he often uses the power of 2n to find the number of ways bits (or units of information) can be arranged. The n often stands for the number of bits.
Antonio is working on programming a new video game called Millie's Quest. In the game, the main character, Millie, collects golden keys to help her in her quest. Antonio wants to write a formula to show that Millie can collect one less key than the highest number of bits that can be arranged in the system. What formula can he use?

Answers

Answer:

Formula = 2n-1

Step-by-step explanation:

Given : Antonio uses the power of 2n to find the number of ways bits can be arranged. The n often stands for the number of bits. Millie, collects golden keys to help her in her quest.

To write : A formula to show that Millie can collect one less key than the highest number of bits that can be arranged in the system.

Number of bits =n

Highest number of bits =2n

One less key than the highest number of bits = 2n-1

Therefore, the formula he use = 2n-1

What is the slope of the line shown below? (enter your answer as a decimal if necessary.)

Answers

Answer: The slope is 2 -Please mark brainliest

1. Find the X and Y values of each point

X1: 1

X2: -1

Y1: 3

Y2: -1

2. Subtract X1 from X2 and Y1 from Y2

Y: -1-3=-4

X: -1-1=-2

3. Divide the X value by the Y value

-4/-2=2

The slope of the line shown on the coordinate plane is 2.

Answer:

Step-by-step explanation:

(X1,Y1)=(1,3)

(X2,y2)=(-1,-1)

slope(m)=y2-y1/x2-x1

= -1-3/-1-1

= -4/-2

= 2

If your annual salary is $68,900, how much would be your salary in 3 years?. Write anEquation and solve the problem
