Answer:
451
Step-by-step explanation:
7, 17, 30, 51, 85, 137, 212
Differences between Difference between Difference between
numbers in sequence first differences second differences
17 - 7 = 10
30 - 17 = 13 3
51 - 30 = 21 8 5
85 - 51 = 34 13 5
137 - 85 = 52 18 5
212 - 137 = 75 23 5
75 + 28 = 103
212 + 103 = 315 28 5
103 + 33 = 136
315 + 136 = 451 33 5
Answer:
The dimensions of constant C are of ![[L^{3}T]^{-4}](https://tex.z-dn.net/?f=%5BL%5E%7B3%7DT%5D%5E%7B-4%7D)
Step-by-step explanation:
It is given that
Since the dimensions of volume are ![[L^{3}]](https://tex.z-dn.net/?f=%5BL%5E%7B3%7D%5D)
Each of the term shall have a dimension of since they are in addition.
Thus for third term we can write
Thus we have
![[L^{3}]=[C][T^{4}]\\\\\therefore [C]=[L^{3}][T^{-4}]](https://tex.z-dn.net/?f=%5BL%5E%7B3%7D%5D%3D%5BC%5D%5BT%5E%7B4%7D%5D%5C%5C%5C%5C%5Ctherefore%20%5BC%5D%3D%5BL%5E%7B3%7D%5D%5BT%5E%7B-4%7D%5D)
Answer:
To solve this equation your goal is to get x by itself
First we need to distribute the 3 through the (2x-7)
x-6x+21=76 (-3*2x=-6x, -7*-3=21)
Your next step is to combine like terms
-5x+21=76 (x-6x=-5x)
Next subtract 21 from both sides
-5x=55 (21-21=0, 76-21=55)
Last you need to divide both sides by -5
x=-11 (-5/-5=1, 55/-5=-11)
x=-11
