13. name the lines that are only in plane q. 14. how many planes are labeled in the figure? 15. name the plane containing the lines m and f 16. name the intersection of lines m and t 17 name a point that is not coplanar with points a, b, and c 18. are points f, m, g, and p coplanar? explain. 19. name the points not contained in a line shown. 20. what is another name for line t? 21. does line n intersect line q? explain.

y=foot

x=foram

a. easy, plug 17 for x and evaluage for y

y=0.860(17)+3.302

y=14.62+3.302

y=17.922 inches

b. rate of change is slope

y=mx+b

m=slope

so

rate or change is 0.860 inches per legnth of forarm

c. what data

d. it is a function

since it is 1st degree (no exponents greater than 1 on the placeholder), and it is not a vertical line

it is a function

answer: $53750

steps:

list the principal and interest after the n-th year:

n       principal   simple interest

1     12500     375

2     25000     750

3     37500     1125

4     50000     1500

sum: $50000     $3750

total at end of year 4: $53750
