Find the derivative of f(x) = negative 5 divided by x at x = 11.
Yuki888 [10]
I want to believe the equation is,
 f(x) = -5/x
This can be written as;

f(x)  = y

y = -5 x⁻¹
derivative = dy/dx = (-1)(-5)x(⁻1-1)
                              = 5x⁻²
 
Derivative at x=11, 

dy/dx = 5(11)⁻²
         = 5/(11²)
         = 5/121

So, the derivative of  f(x) = -5/x at x=11 is 5/121.

The world’s fastest train travels about 162 mi/h. Estimate how far the train travels in 4.75 h.
kirill [66]
When using estimation, we usually will round up or down depending. 

162= rounds down to 160

4.75= rounds to 5

160*5= 800

It travels around 800 miles in 5 hours.

I hope this helps!

A certain journal likes to give new writers an opportunity. Therefore, there is a 40% chance that an author’s first article subm
kicyunya [14]

Answer:

a

P(A_4) =  0.077  

b

P(A_5) =0.7542

Step-by-step explanation:

From the question we are told that

    The chance that a new authors first article will be submitted is  P(A) =  0.40

    The chance that a new authors next article will be submitted is  P(N) =  0.20

Generally the probability that a new author first article is not published is

      P(A)' = 1 - 0.4 =  0.6

Generally the probability that a new author next articles are not published is  

      P(N)' = 1 - 0.2 =  0.8

Now from the question we are told to obtain the probability that a new author will be published for the first time when he or she  submits a 4th article, which implies that the new authors first three articles where not published

So the probability is mathematically represented as

   P(A_4) =  P(A)' *  P(N)' * P(N)' * P(N)    

=> P(A_4) =  0.6 * 0.8 * 0.8* 0.2  

=> P(A_4) =  0.077  

Generally the probability that a new author will be published for the first time within his or her first 5  articles submitted is equivalent to

1 - [The probability that a new author will not be published for the first time

    within his or her first 5  articles submitted]

Now the  probability that a new author will not be published for the first time within his or her first 5  articles submitted. is mathematically represented as

    P(A_5)' = P(A)' * P(N)' * P(N)'*P(N)'* P(N)'

=> P(A_5)' = 0.6 *0.8 * 0.8'*0.8* 0.8

=>   P(A_5)' = 0.24576

Generally the probability that a new author will be published for the first time within his or her first 5  articles submitted is mathematically represented as

    P(A_5) = 1 - P(A_5)'

=>  P(A_5) = 1 -0.24576

=>  P(A_5) =0.7542
