The graph equation
From the graph, we have:


The slope of the graph is:




So, the graph equation is:




In standard form, we have:

The x coordinate of S will be 1/2 * 2a = a.
and since the half triangle is 30-60-90 the y coordinate will be sqrt3 a
so S is (a , sqrt3a)
To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.
Divide: 4(/7) / 2 = 4/7 · 1/2 = 4*1/ 7*2 = 4/14 = 2/7
Answer: $30.44
Step-by-step explanation:
$30 20% of tht is 6
30-6=24
tax is 6.4% which is 1.94
24+1.94 which equals $25.94
tips is 15% 4.5 so we add that to $25.94
so total is $30.44
Special Triangles Theorem
leg1=leg2=a
hypotenuse=a√2=10
Both Legs are 5√2 inches
