Answer:
4/52 or 1/13
Step-by-step explanation:
there are only 4 kings; diamond, Heart, Spades and Clubs.
You could use 4(division) sign 25 + 3 (division sign) 15 * 10, ok?
I believe this is pythag
15^2 x 11^2 = 27225
(square root) of 27225 = 165
165ft
Answer:
I do 1 option for you as an example, you need to check the leftover by yourself.
Step-by-step explanation:
for d) y(0) = 0 and y'(pi) =0
![y(0) = C_1e^0cos(0)+ C_2 e^0 sin(0) = 0 \longrightarrow C_1 = 0](https://tex.z-dn.net/?f=y%280%29%20%3D%20C_1e%5E0cos%280%29%2B%20C_2%20e%5E0%20sin%280%29%20%3D%200%20%5Clongrightarrow%20C_1%20%3D%200)
![y(x) ' = C_1e^x cos(x) - C_1e^x sin (x) + C_2e^x sin(x) + C_2e^x cos(x)](https://tex.z-dn.net/?f=y%28x%29%20%27%20%3D%20C_1e%5Ex%20cos%28x%29%20-%20C_1e%5Ex%20sin%20%28x%29%20%2B%20C_2e%5Ex%20sin%28x%29%20%2B%20C_2e%5Ex%20cos%28x%29)
![y(\pi)'=C_1e^\pi cos(\pi)- C_1e^\pi sin(\pi)+ C_2e^\pi sin(\pi) + C_2e^\pi cos (\pi)](https://tex.z-dn.net/?f=y%28%5Cpi%29%27%3DC_1e%5E%5Cpi%20cos%28%5Cpi%29-%20C_1e%5E%5Cpi%20sin%28%5Cpi%29%2B%20C_2e%5E%5Cpi%20sin%28%5Cpi%29%20%2B%20C_2e%5E%5Cpi%20cos%20%28%5Cpi%29)
Replace
we have
if and only if ![C_2 =0](https://tex.z-dn.net/?f=C_2%20%3D0)
Hence the given solution does not work.
then, d is NOT the correct answer.
