Answer:
151
Step-by-step explanation:
You would round to 0.12, What you would do is look at the placement of each number. The 1 is in the tenths place, the 2 is in the hundreds and the 3 is in the thousands. So you look at the three and see if you would round up or down, if it is 5 or greater you round up if it is 4 or less then round down. This is less so you would round down to 0.12
Answer:
A= 42.5
Step-by-step explanation:
2*5= 10
10/2=5
2*2= 4
4/2=2
5+2+4=11
3.5*9= 31.5
31.5+11=42.5
Sorry if this is wrong if it is wrong please let me know I think I know what I did wrong if it is wrong
Let's make a table of differences
0 3 8 15 24
3 5 7 9
2 2 2
Constant second difference means a quadratic polynomial,
f(n)=an² + bn +c
f(1)=0, f(2)=3, f(3)=8
0 = a+b+c
3 = 4a + 2b + c
8 = 9a + 3b + c
Subtracting pairs
3 = 3a+b
5 = 5a + b
Subtracting,
2 = 2a
a = 1
b = 5 - 5a = 0
c = -a-b = -1
f(n)=n² -1
Duh, shoulda noticed that at the beginning.
f(17)=17²-1 = 288
a₁ =5
aₙ = aₙ₋₁ - 7
aₙ = a₁ + d(n-1)
aₙ = 5 - 7(n-1)
a₇ = 5 - 7(6) = -37
Answer: -37
