Answer:
pay attention in class next time, love
I would use the distance formula: d=√(x2-x1)^2+(y2-y1)^2
(2.7, 5.1) is the first point and (3, 4.7) is the second point
d=√(3-2.7)^2+(4.7-5.1)^2
d=√(.3)(.3)+(-.4)(-.4)
d=√0.09+0.16
d=√0.25
d=0.5 so B
Hope this helps

Answer:
19404
Step-by-step explanation:
sum of arithmetic series is
Sn = n/2 (2a + (n-1)d)
or
Sn = n/2 (a + an)
a = 1st unit
an = last unit
d = difference
8-3 or 13-8 so d = 5
then first step is to find the value of n
an = a + (n-1)d
438 = 3 + (n-1)5
438 - 3 = 5n - 5
435 = 5n - 5
435 + 5 = 5n
440 = 5n
n = 440/5
n = 88
then we can find the sum
Sn = 88/2 (3 + 438)
S88 = 19404
