Answer:
21 matches
Step-by-step explanation:
This is a combination problem where we have to select two member out of 7 members
So we want calculation of 7C2
7C2 = 7!/[(2!)(7-2)!]
(7*6*5*4*3*2*1)/[(2*1) *(5*4*3*2*1]
(7*6)/2 ~ Note everything that easily cancels here!
42/2
21 matches

Step-by-step explanation:
Answer:
y =
+ 
Step-by-step explanation:
y''- 9 y' + 18 y = t²
solution of ordinary differential equation
using characteristics equation
m² - 9 m + 18 = 0
m² - 3 m - 6 m+ 18 = 0
(m-3)(m-6) = 0
m = 3,6
C.F. = 
now calculating P.I.


hence the complete solution
y = C.F. + P.I.
y =
+ 
We are required to find the total hours David and Xavier works in a week
The total hours David and Xavier works in a week is 70 hours
let
number of hours Xavier works = 32 hours
number of hours David works = (6 + 32) hours
= 38 hours
<em>Total number of hours David and Xavier works in a week = number of hours Xavier works + number of hours David works</em>
= 32 hours + 38 hours
= 70 hours
Therefore, the total hours David and Xavier works in a week is 70 hours
