Each of them would have to see 5 movies to pay the same amount.

Explanation;

Members have to pay $30 a month just to have a lower admission fee. So members already start with a high price. If you add 7.95 together 5 times you get 39.75. This is the same as the members when you add the $30 admission fee to the 5 movies. (30+1.95....). That is how you find that both members and nonmembers will be paying the same amount after both watching 5 movies.

use analytic methods to find the extreme values of f(x)= (1/x) + lnx on the interval 0.5 ≤ x ≤ 4 and where they occur

natali 33 [55]

F(x) = (1/x) + ln x
At the extreme values, f'(x) = 0
f'(x) = -1/x^2 + 1/x = 0
(x - 1)/x^2 = 0
x - 1 = 0
x = 1

f(1) = 1/1 + ln 1 = 1

Therefore, the extereme value is 1 and occurs at x = 1.

Complete the function remove_all(L, x) so that, given a list L and a target value x, it returns a copy of the list that excludes

tia_tia [17]

Answer:

Code is given below along with explanation and output.

Step-by-step explanation:

we can use the method of list comprehension to achieve the given task.

In a list comprehension, we create a sub-list of elements which satisfy specific conditions. the condition i !=x makes sure that x would be excluded in the modified list.

def remove_all(L, x):

return [i for i in L if i != x]

L = [1, 2, 3, 4, 5, 6, 4, 3, 2, 4 ]

print('Before =',L)

L = remove_all(L, 4)

print('After =',L)

Output:

Before = [1, 2, 3, 4, 5, 6, 4, 3, 2, 4]

After = [1, 2, 3, 5, 6, 3, 2]

As you can see we have successfully removed the multiple occurrence of x=4 while preserving the order of the list.

Hello,

oksano4ka [1.4K]

It took him 9.92 hours to complete the journey.

Step-by-step explanation:

Given,

Distance traveled = 50 miles

Distance traveled on horse = $\frac{50}{2}=25\ miles$

Distance traveled on foot = 25 miles

Speed while riding = 9 miles per hour

Distance = Speed * Time

Time while riding = $\frac{Distance}{Speed}$

Time while riding = $\frac{25}{9}=2.78\ hours$

Speed while waling = 3.5 miles

Time = $\frac{25}{3.5}=7.14\ hours$

Total time = 2.78+7.14 = 9.92 hours

It took him 9.92 hours to complete the journey.

Keywords: speed, distance
