An algorithm takes 0.5 seconds to run on an input of size 100. How long will it take to run on an input of size 1000 if the algo

dexar [7]

Answer:

linear: 5s

quadratic: 50s

log-linear: 0.75 s

cubic: 500s

Step-by-step explanation:

Let $t_1,t_2$ be the running time associated with the input of sizes $s_1,s_2$

If the running time is linear

$t_2 = t_1\frac{s_2}{s_1} = 0.5*\frac{1000}{100} = 0.5*10 = 5s$

If the running time is quadratic

$t_2 = t_1\left(\frac{s_2}{s_1}\right)^2 = 0.5*\left(\frac{1000}{100}\right)^2 = 0.5*10^2 = 50s$

If the running time is log-linear

$t_2 = t_1\frac{log(s_2)}{log(s_1)} = 0.5*\frac{log(1000)}{log(100)} = 0.5*1.5 = 0.75s$

If the running time is cubic:

$t_2 = t_1\left(\frac{s_2}{s_1}\right)^3 = 0.5*\left(\frac{1000}{100}\right)^3 = 0.5*10^3 = 500s$

11111nata11111 [884]

Answer:

$P=4.41205084*10^2^1$

Step-by-step explanation:

From the ques ton we are told that

Total amount N=15

Choices within 10 pop, 25 reggae, 10 blues

Generally for equal amount in her play list she's mathematically Going to have 5 of each kind Pop,Reggae,Blues

Therefore

Let the amount of differnt playlist be given as P

$P=^1^0C_5*^2^5C_5*^1^0C_5*15!$

$P=252*53130*252*1307674368000$

$P=4.41205084*10^2^1$

Therefore $P=4.41205084*10^2^1$ different playlists are possible
