We have that
cos(alfa)=0.2546
arc cos (0.2546)=75.2501---------- > 75.25°
the answer is 75.25°
Answer: slope intercept is y=mx+b form s b= the y intercept and x will just be x and the m is usually a fraction which tells you the slope so what you need to do is mark these points on a line graph draw a line from one to the other and every where it crosses over a point is where you can find the slope and the y intercept giving you the answer
Find attached a graph that I constructed.
To do that graph I used Excel.
First I did a table with this set of points:
<span><span><span>height presuure
</span>
<span>
miles psi
</span>
<span>
0
14,7
</span>
<span>
<---- initial data
3.6 7.35
</span>
<span>
<--- increase hegiht 3.6 miles => half pressure
7.2
3.675
</span>
<span>
<---- second increase of 3.6 miles in height
10. 8
1.8375
</span>
<span>
<---- third increase of 3.6 miles in height
14.4
0.91875
</span>
<span>
18 0.459375
</span>
</span></span>
Answer:
0.80
Step-by-step explanation:
2.10-1.45=0.65
0.65=1 baugette
1.45-0.65=0.8
0.8=1 cup
