Answer:

quadratic

Step-by-step explanation:

The x-values are sequential, so we can look at the y-values.

Differences from one to the next are ...

-7, -1, 5, 11, 17

And the differences of these numbers are ...

6, 6, 6, 6

When <em>second</em> differences are constant, the sequence can be produced by a <em>second</em>-degree (quadratic) polynomial.

Here, that polynomial is ...

y = 3x² +2x -1

The regression functions of a graphing calculator can help you find the appropriate formula.

So can anyone help me with #1 and 2 and show work I have no idea what I’m doing

Answer:

x = 44*2

x = 62*2

x = 108/2

x = 160/2

12x = 60*2

12x = 120

x = 120/12

5x = 50/2

5x = 25

x = 25/5

If a pine tree grows 4 inches per year, how long will it take for the tree to reach a height of 13 feet?

attashe74 [19]

Answer:

Should be 39 years.

there is 12 inches in a foot. and if the tree grows 4 inches every year, then in 3 years the tree would be 1 foot. 13 x 3 = 39, thus proving that in 39 years, it will be 13 feet tall. I may be wrong but this sounds correct.

The minute hand of a clock is 8 inches long and moves from 12 to 8 o’clock. How far does the tip of the minute hand move?

ryzh [129]

The minute hand is like an eight inch radius of a circle, whose circumference would equal 2 * PI * 8 = 50.265 inches. By moving to 8 o'clock, it travels 2/3 of the circumference or 50.265 * 2/3 = 33.510 inches
