Answer:
A
Step-by-step explanation:
Start with the 3.
You know that there is a difference of 4 between (say) 2 and 5. The 3 is a sign that the sequence is increasing. The members of the sequence are going up.
n - 1 means that the nth terms is calculated as an and uses the number of terms to be n-1. That means that the first term is a1 which is the starting point of the sequence.
The answer is an = a1 + (n-1)*d
d = 3
a1 = - 7
So let's try the formula out.
a4 = -7 + (4 - 1)*3
a4 = -7 + 3 * 3
a4 = -7 + 9
a4 = 2
Is 2 the 4th term in the series? Yes it is!
Answer:
0,05
Step-by-step explanation:
1)First, Let’s find the mean of the data table
12 + 10 + 12 + 6 + 8 + 4 + 2 + 12 = 66
66 ÷ 8 = 8,25
2)12 - 8,25 = 3,75
10 - 8,25 = 1,25
12 - 8,25 = 3,75
6 - 8,25 = -1,75
8 - 8,25 = -0,75
4 - 8,25 = -3,75
2 - 8,25 = -5,75
12 - 8,25 = 3,75
3) 3,75 + 1,25 + 3,75 - 1,75 - 0,85 - 3,75 - 5,75 + 3,75 = 0,4
0,4 ÷ 8 = 0,05
Answer:
y^2
Step-by-step explanation:
2y^3 + y^2 and 4y^4 + 2y^3
2y^3 + y^2......factor out y^2
y^2(2y + 1)
4y^4 + 2y^3...factor out y^2
y^2(4y^2 + 2y)
I would normally factor out 2y^3 out of this one...but u cant do it in the other one...the only common factor is gonna be y^2
the common factor is y^2 <===
Suppose 
is a solution to the ODE. Then 
and 
, and substituting these into the ODE gives
Then the particular solution to the ODE is
divide by a number that goes into both numbers equally with out making a decimal... answer: 13/3
i think i did it right but u might wanna use a calculator, i dont like using them lol
