Answer: Choice D. 2, 6, 12, 20</h3>
=============================================
Work Shown:
Plug in n = 1
c(n) = n(n+1)
c(1) = 1(1+1)
c(1) = 1(2)
c(1) = 2
The first term is 2
-------------
Plug in n = 2
c(n) = n(n+1)
c(2) = 2(2+1)
c(2) = 2(3)
c(2) = 6
The second term is 6
-------------
Plug in n = 3
c(n) = n(n+1)
c(3) = 3(3+1)
c(3) = 3(4)
c(3) = 12
The third term is 12
-------------
Plug in n = 4
c(n) = n(n+1)
c(4) = 4(4+1)
c(4) = 4(5)
c(4) = 20
The fourth term is 20
-------------
The first four terms are: 2, 6, 12, 20
1,609 meters = 1 mile
10,095 meters = 10,095/1,609 = 6.3 miles
Therefore, <span>10095 meters/seconds = 6.3 miles/seconds</span>
Answer:
1/10
Step-by-step explanation:
1 + 1/2 = 1 1/2
1 - 1/8 = 7/8
1 + 1/5 = 1 1/5
1 - 1/3 = 2/3
1 + 1/10 = 1 1/10
One and one tenth is closest to one because one tenth is the smallest amount that would need to be added or taken away to get exactly one. Hope I helped!
F(x)=-3.25x +22.41
f(-4.2)= 3.25(-4.2)+22.41 = 8.76
