His average speed is 2.27 meters per second
Answer:
Close to 160 but not quite 160
Step-by-step explanation:
360 /3 is 120
Sorry if wrong
1) To calculate maximum of f(t) function we first need to find derivative of it:
f(t)' = 10(e^(-t/8) + t*e^(-t/8)*(-1/8)) = 10(e^(-t/8) -t/8*e^(-t/8)) = 10e^(-t/8)(1-t/8)
the condition is:
f(t)' = 0 that means:
0 = 10e^(-t/8)(1-t/8)
10t/8*e*(-t/8) = 10*e^(-t/8)
t/8 = 1
t = 8
The answer is 8 days.
2) that percent we will get simply by expressing t=8 in our equation.
f(8) = 10*8*e^(-1) = 80/e = 29.43%
It is the LCM of 176 & 342
176 = 2^4 * 11
342 = 2 * 3² * 19
2^4*11*2*3²*19 =
30096 is your answer
