What are the coordinates of the turning point for the function f(x) = (x - 1)3 - 3? A. (-1, -3) B. (-1, 3)

C. (1, -3)

D. (1, 3)

Answers

ANSWER

The turning point is




EXPLANATION


The function given to us is



At turning point,


So we need to differentiate the given function and equate it to zero.



We using the chain rule of differentiation, we obtain,


We equate this to zero to obtain,








We divide through by 3.




We solve for x to get,







We substitute this x-value in to the function to obtain the corresponding y-value of the turning point.















Therefore the turning point is




C is the correct answer.

Answer:  C. (1, -3)

Step-by-step explanation:

Given function,

  -------(1)

By differentiating the above equation with respect to x,

At the turning point of the function f(x),

f'(x) = 0

⇒  

By substituting this value in equation (1),

We get,

f(x) = - 3

Hence, the turning point of the function f(x) is (1,-3).

⇒ Option C is correct.

A small grocery store had 10 cartons of milk, 2 of which were sour. If you are going to buy the 6th carton of milk sold that day at random, find the probability of selecting a carton of sour milk.

Answers

Answer:

The probability that the sixth customer buys sour milk is .

Step-by-step explanation:

The grocery store has a total of 10 cartons of milk.

The number of cartons of milk that are sour is, 2.

  • If none of the sour cartons of milk were bought by the first 5 buyers, then the probability of this event is:

       P (Both the sour cartons are available to be sold to the sixth customer)

        =

  • If only one sour carton of milk is sold to the first 5 buyers then the probability is:

        P (Only one sour cartons is available to be sold to the sixth customer)

            =

  • If both the sour carton of milk is sold to the first 5 buyers then the probability is:

        P (None of the sour cartons is available to be sold to the sixth customer)

         =

Compute the probability that the sixth customer buys sour milk:

= P (Both sour milk is available for the 6th customer) +  

      P (Only one sour milk is available for the 6th customer) +  

          P (None of the sour milk is available for the 6th customer)

Thus, the probability that the sixth customer buys sour milk is .

If 3 3/4 pounds of candy cost $20.25, how much is 1 pound of candy

Answers

3 and 3/4lb=20.25
what you should do is divide both sides by 3 and 3/4 but that isnt nice

convert 3 and 3/4 to improper
3 and 3/4=3+3/4=12/4+3/4=15/4
15/4lb=20.25
times 4/15 to both sides (15/4 times 4/15=60/60=1)
1lb=81/15
1lb=5.4

answer is
1lb=$5.40

in a rowing race, the distance between the teams in first place and second place is 5.7 meters. The distance between the teams in second and third place is one third that distance. How much farther ahead is the team in first place than in third?

Answers

Answer:7.6

Step-by-step explanation:

Given

Distance between first team place and second place is  5.7 meters

And distance between the teams in second and third place is one third that distance i.e.

so the distance between the first team and the third team is

5.7+1.9=7.6 m

Distance between 1st and 2nd is 5.7 meters
Distance between 2nd and 3rd is (1/3) of 5.7 meters.
So the distance between 1st and 3rd is:

5.7 + (1/3)(5.7) = 5.7 + 1.9 = 7.6 meters
