21.5
Answer:
The common difference is 3
Step-by-step explanation:
we know that
In an <u>Arithmetic Sequence</u> the difference between one term and the next is a constant called the common difference
we have
![5,8,11,14](https://tex.z-dn.net/?f=5%2C8%2C11%2C14)
so
![a1=5](https://tex.z-dn.net/?f=a1%3D5)
![a2=8](https://tex.z-dn.net/?f=a2%3D8)
![a3=11](https://tex.z-dn.net/?f=a3%3D11)
![a4=14](https://tex.z-dn.net/?f=a4%3D14)
![a2-a1=8-5=3](https://tex.z-dn.net/?f=a2-a1%3D8-5%3D3)
![a3-a2=11-8=3](https://tex.z-dn.net/?f=a3-a2%3D11-8%3D3)
![a4-a3=14-11=3](https://tex.z-dn.net/?f=a4-a3%3D14-11%3D3)
therefore
The common difference is 3
Answer:
7/33 = 21 repeating and I'm pretty sure the question wants you to write it as an improper fraction. so your answer would be 40/33
Step-by-step explanation:
The magnitude of WX is
⇒ c
Step-by-step explanation:
The magnitude of XY (its length) where,
is IXYI =
∵ W = (-2 , 8 , -3)
∵ X = (1 , 4 , -1)
- To find the magnitude of WX use the formula above
∴
= -2 and
= 1
∴
= 8 and
= 4
∴
= -3 and
= -1
- Substitute these values in the rule above
∵ IWXI =
∴ IWXI =
The magnitude of WX is

You can solve this by using the system of equations.
Jan - 4.95 = 2H + 3C
Wayne - 5.45 = 3H + 2C
Use elimination.
-3(2H + 3C = 4.95)
2(3H + 2C = 5.45)
Solve. And you'll get:
-6H + (-9C) = -14.85
6H + 4C = 10.9
Cross out -6H and 6H because they cancel out. And you're left with:
-9C = -14.85
4C = 10.9
Add -9C with 4C, and -14.85 with 10.9.
-5C = -3.95
Divide each side with -5.
C = $0.79
Now to figure out what H is, just substitute the C in one of the equations with 0.79.
5.45 = 3H + 2(0.79)
5.45 = 3H + 1.58
-1.58 -1.58
3.87 = 3H
3.87/3 = 3/3(H)
1.29 = H
Finished!
