Answer:
12
Step-by-step explanation:
To find the mean, we add up all the numbers and divide by the number of numbers
(19+ 12+9+ 6+ 12+ 8+ 18+ 12+ 14+ 10)/10
120/10

Step-by-step explanation:
3 ^6= 6x6x6
4 ^5= 4x4x4x4x4
6 ^3=3x3x3x3x3x3
5 ^4= 4x4x4x4x4
By letting

we get derivatives


a) Substitute these into the differential equation. After a lot of simplification, the equation reduces to

Examine the lowest degree term
, which gives rise to the indicial equation,

with roots at r = 0 and r = 4/5.
b) The recurrence for the coefficients
is

so that with r = 4/5, the coefficients are governed by

c) Starting with
, we find


so that the first three terms of the solution are

Answer:
r = ±√47
Step-by-step explanation:
-7r^2 = -329 . . . . given
r^2 = 47 . . . . . divide both sides by -7 (multiplication property of equality)
r = ±√47 . . . . square root both sides (square root property of equality)
