Pretty hard question
marishachu [46]

Answer:

D

Step-by-step explanation:

Take x = 1.

Now substitute in the function.

f(1) = 3 + √1

f(1) = 3 + 1

f(1) = 4

Now, we know the line of the function passes through 2 points : (0, 3) and (1, 4). Graph D shows these features.

The volume of a sphere is 2254 pi m^3 what is the surface area of the sphere to the nearest 10th
Advocard [28]
By definition. The volume of the sphere is:
 V = (4/3) * (pi) * (r ^ 3)
 Where,
 r: radius of the sphere.
 Substituting values:
 2254 pi = (4/3) * (pi) * (r ^ 3)
 Clearing the radio we have:
 r ^ 3 = (3/4) * (2254)
 r = ((3/4) * (2254)) ^ (1/3)
 r = 11.91255883
 Then, the surface area is:
 A = 2 * pi * r ^ 2
 Substituting values:
 A = 2 * 3.14 * (11.91255883) ^ 2
 A = 891.6 m ^ 2
 Answer:
 
The surface area of the sphere is:
 
b. 891.6 m ^ 2

Students are going through a three-step process to obtain their ID cards. Each student will spend 2 minutes at the registration
GREYUIT [131]

Answer:

Time taken to process 20 students is 100 minutes.

Step-by-step explanation:

Given that:

Students are going through a three-step process to obtain their ID cards.

Let Have a table below illustrating what the question means:

Unit                                   Number of                    Number of

<u>                                           servers                         minutes spent</u>

Registration                            1                                    2

desk            

Cashier                                    3                                   10

ID processing                          4                                   20

<u>station                                                                                               </u>  

Demand Rate = 0.5 student per minute

To calculate how long it take to process 20 students assuming the system is full; we need to run through the following process:

The Capacity of each of the server at three-processes is calculated as;

Capacity = Number of students served per minute

At the Registration desk

Number of minutes spent to serve 1 student = 2 minutes

Number of servers to be = 1

Therefore, the Capacity=  \frac{1}{2}

= 0.5 students per minute

At the Cashier  Unit

Number of minutes spent to serve 1 student = 10 minutes

and we have number of servers to be  = 3

Thus, the Capacity = \frac{3}{10}

= 0.3 students per minute

Over to the ID processing station

Number of minutes spent to serve 1 student = 20 minutes

Number of servers = 4

The capacity=\frac{4}{20}

=  0.2 students per minute

In the three-step process, the bottleneck process is the  ID processing stations and this process also have the highest time to  serve 1 student.

As such, the process capacity is equivalent to the bottleneck process

Process Capacity = 0.2 students per minute

As we know that our demand rate = 0.5 students per minute

Since, the demand rate is higher than the Process capacity, the number of students served per minute  will still be:

Number of students served per minute = 0.2

Time taken to serve 1 student = 1 / 0.2 = 5 minutes

Time to process 20 students = 5 × 20 =100 minutes.
