Answer:
4×2=8
8×2=16
16×2=32
32×2=<em>6</em><em>4</em>
<em>6</em><em>4</em><em>×</em><em>2</em><em>=</em><em>1</em><em>2</em><em>8</em>
<em>1</em><em>2</em><em>8</em><em>×</em><em>2</em><em>=</em><em>2</em><em>5</em><em>6</em>
<em>I </em><em>HOPE</em><em> THIS</em><em> HELPS</em><em> U</em>
We have the following functions:
f (x) = x3 - 3x2 - 13x + 15
f (x) = x4 + 3x3 - 8x2 + 5x - 25
f (x) = x3 - 2x2 - x + 2
f (x) = -x3 + 13x - 12
Factoring we have:
f (x) = x3 - 3x2 - 13x + 15 -------> x + 3
f (x) = x4 + 3x3 - 8x2 + 5x - 25 -> x + 5
f (x) = x3 - 2x2 - x + 2 ------------> x - 2
f (x) = -x3 + 13x - 12 -------------> x + 4
[1] Amount of water per minute
Water Miser: m = 3.0 gal/min
Watersaver: m = 2.5 gal/min
Waterstream: m = 1.5 gal/min
[2] Equations:
I would suggest using y = mx.
Water Miser: y = 3x
Watersaver: y = 2.5x
Waterstream: y = 1.5x
[3] For 6,8,10, and 12 minutes:
Plug in x = 6, x = 8, x = 10, and x = 12 into each of the three equations and record the y-values.
[4] Which would you buy?
Depends on your personal opinion.
Want to save the earth? Pick the one that uses the least amount of water.
Want to have a waterfall for a shower? Pick the one that uses the most amount of water. :)
A circle has 360 degrees, therefore, all you need to do is subtract.
360-111-104-104=X
X=41 degrees.
Hope this helps
