Answer:
For First Solution: 
is the solution of equation y''-y=0.
For 2nd Solution:
is the solution of equation y''-y=0.
Step-by-step explanation:
For First Solution:
In order to prove whether it is a solution or not we have to put it into the equation and check. For this we have to take derivatives.
First order derivative:
2nd order Derivative:
Put Them in equation y''-y=0
e^t-e^t=0
0=0
Hence is the solution of equation y''-y=0.
For 2nd Solution:
In order to prove whether it is a solution or not we have to put it into the equation and check. For this we have to take derivatives.
First order derivative:
2nd order Derivative:
Put Them in equation y''-y=0
cosht-cosht=0
0=0
Hence is the solution of equation y''-y=0.
Y=mx+b
Y= -14(x-5)+4
Y= -14x+70+4
Y= -14x+74
Plot (0,74)
Then move down 14 then over left 1
Answer: I encourage you to ask real questions for the sake of others.
Step-by-step explanation: (thx for points tho :))
Joey has 21 socks all in all. Out of them, there are 10 dress socks and 13 brown socks. There are 7 brown dress socks. The probability,
P (brown or dress) = P (brown) + P (dress) - P (brown and dress)
Substituting,
P(brown or dress) = 13/21 + 10/21 - 7/21 = 16/21
Thus, the answer is 16/21.
