Answers

Answer 1

Answer:

21.5 cu. cm.

Step-by-step explanation:

Volume of a pyramid is

V = 1/3Bh       B = area of the base          h = height of pyramid

V = 1/3(7.5)(8.6)

   = 21.5 cu. cm.

Renae has been playing Tower of Hanoi and has noticed that the minimum number of moves it takes to defeat the game is related to the number of disks she must move. She has recorded her observations below. Write an equation that describes this pattern. Show your work.


Number of Disks in the Tower ║Minimum Number of Moves

1 ║1

2║ 3

3 ║7

4 ║15

5 ║31

Answers

Answer:

[tex]y = 2^x - 1[/tex]

Step-by-step explanation:

Let the number of disks be x and the minimum number of moves be y.

[tex]y = 2^x - 1[/tex]

When x = 1: y = 1

[tex]y = 1 = 2 - 1 = 2^1 - 1[/tex]

When x = 2: y = 3

[tex]y = 3 = 4 - 1 = 2^2 - 1[/tex]

When x = 3: y = 7

[tex]y = 7 = 8 - 1 = 2^3 - 1[/tex]

When x=4: y = 15

[tex]y = 15 = 16 - 1 = 2^4 - 1[/tex]

When x = 5: y = 31

[tex]y = 31 = 32 - 1 = 2^5 - 1[/tex]

Notice that for each derived expression of y, the exponent of 2 is being replaced by the value of x.

The general equation is: [tex]y = 2^x - 1[/tex]

slope is 1/2 (change in y/change in x) y intercept is 2 (where the line crosses the y axis) so the equation is y=1/2x+2

Answer:

The y-intercept is 2 and the slope is 1/2. So the equation is y = 1/2x + 2

Step-by-step explanation:

The y-intercept is where the line starts on the y-axis. For the slope to the next point on the line you have to move 2 units to the right and 1 unit up. When writing the slope as a fraction, you always put how far you move up or down above how far you move to the right or left.

Answer:

y = -3/4x -5

Step-by-step explanation:

(4, -8) and (-8, 1)

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

m= (1+8)/(-8-4)

m = (9)/(-12)

m = -3/4

y - y1 = m(x-x1)

y + 8 = -3/4(x -4)

y + 8 = -3/4x + 3

y = -3/4x -5

Answer:

y = -3/4x - 5
