Answer:

C(x) = $850 - $350x

Monthly Profit = -500x² + 1550x - 850

x = $1.55

the largest possible monthly profit = $351.25

Step-by-step explanation:

Given:

Demand equation:

q = -500x + 1200

where, q is the number of users who log on per month

x is the log-on fee you charge

Site maintenance fee = $10 per month

High-volume access fee = $0.70 per log-on

Now,

C(x) = $10 + ( $0.70 × q )

C(x) = $10 + ( $0.70 × (-500x + 1200) )

C(x) = $10 + ( - $350x + 840 )

C(x) = $850 - $350x

Total monthly income = qx

Total monthly income = ( -500x + 1200 ) × x

Total monthly income = -500x² + 1200x

now,

Profit = Income - cost

Monthly Profit = -500x² + 1200x - ( 850 - 350x )

Monthly Profit, P(x) = -500x² + 1550x - 850

For the largest possible monthly profit

$\frac{d\textup{P(x)}}{\textup{dx}}$ = 0

$\frac{d(-500x^2+1550x-850)}{\textup{dx}}$ =0

-2 × 500x + 1550 = 0

-1000x + 850 = 0

x = $1.55

Now,

the largest possible monthly profit will be at x = $1.55

substitute in the function of profit

P(1.55) = ( -500× 1.55² ) + ( 1550 × 1.55 ) - 850

the largest possible monthly profit = - 1201.25 + 2402.5 - 850

the largest possible monthly profit = $351.25

Which frame processing method causes a switch to wait until the first 64 bytes of the frame have been received before forwarding

malfutka [58]

Fragment free frame processing method causes a switch to wait until the first 64 bytes of the frame have been received before forwarding the frame to the destination device

Fragment free processing

An advanced type of cut-through switching is fragment-free (runtless switching). Before making a switching choice, switches engaged in cut-through switching merely read the Ethernet frame's destination MAC address field.

What distinguishes fragment-free switching from fast forward switching?

The latency in fast-forward mode is calculated between the first bit received and the first bit delivered. The most common cut-through switching technique is fast-forward switching. Switching without fragments: The switch stores the first 64 bytes of the frame in fragment-free switching before forwarding.

2) Gas mileage is the number of miles you can drive on a a gallon of gasoline.

Harman [31]

Answer:

You could drive 2805 miles on 55 gallons of gas

The car's gas mileage is 51 miles per gallon

Step-by-step explanation:

First, find the gas mileage by dividing the given number of miles by the number of gallons:

510/10

= 51

The car's gas mileage is 51 miles.

Find how far you can drive on 55 gallons of gas by multiplying 51 by 55

51(55)

= 2805

So, you can drive 2805 miles.

A refrigerator contains 50 pieces of fruit: 6 apples, 5 oranges, 10 bananas, 3 pears, 7 peaches, 11 plums, and 8 mangos.Imagine

Marta_Voda [28]

Answer:

The probability that you will pull a banana on the first try and an apple on the second try = .024

Step-by-step explanation:

Given -

A refrigerator contains 50 pieces of fruit: 6 apples, 5 oranges, 10 bananas, 3 pears, 7 peaches, 11 plums, and 8 mangos .

Total no of fruit = 50

The probability that you will pull a banana on the first try and an apple on the second try = $\frac{10}{50} \times \frac{6}{50}$

= $\frac{6}{250}$

= .024
