Disposable medical device sterilization packaging, medical device packaging manufacturers under the

Reused medical devices should be sent to the center for sterilization immediately after using up the large roll. （）

a.That's right. b.Mistake.

Correct answer: B

，；y=, first of all, but due to the limitation of production capacity, it is impossible to produce all type A masks within 8 days, assuming that the spine is produced in the most t days, then (Ling Shidan 8-t) days to produce type B, according to the meaning of the topic: , the solution is t=7, so the maximum value of x can only be, so the range of the value of x is;

To make y obtain the maximum value, because y = is a one-time function, and y increases with the increase of x, so when x takes the maximum value, y takes the maximum value of 10,000 yuan), that is, arrange the production of type A 10,000, type B 10,000, so that the total profit obtained is the largest, the maximum profit is 10,000 yuan, if you want to complete the task in the shortest time, all the production of type B takes the shortest time, but to produce type A 10,000, therefore, in addition to the production of type A 10,000, the rest of the 10,000 should be changed to the production of type B, and the shortest time required is the ruler disturbing the day).

1) The factory produces A-type masks, which can be used to destroy socks for profit.

10,000 yuan Type B masks can be profitable.

10,000 yuan 2)y=

y=Because 50,000 oranges are produced within 8 days of the rounded shed, A can produce up to 7 days.

x range: y range:

3) Maximize benefits: produce as much as possible.

Type A: 10,000.

Type B: 10,000 pieces.

The maximum profit is: 10,000 yuan

①，；y=, first of all, but due to the limitation of production capacity, it is impossible to produce all type A masks within 8 days, assuming that the maximum production of type A is carried out in t days, then (8-t) days to produce type B, according to the meaning of the topic:, the solution is t=7, so the maximum value of x can only be, so the value range of x is;

To make y obtain the maximum value, because y = is a one-time function, and y increases with the increase of x, so when x takes the maximum value, y takes the maximum value of 10,000 yuan), that is, arrange the production of type A 10,000, type B 10,000, so that the total profit obtained is the largest, the maximum profit is 10,000 yuan, if you want to complete the task in the shortest time, all the production of type B takes the shortest time, but to produce type A 10,000, therefore, in addition to the production of type A 10,000, the rest of the 10,000 should be changed to the production of type B, and the shortest time required is days).

，；y=, first of all, but due to the limitation of production capacity, it is impossible to produce all type A masks within 8 days, assuming that the maximum production of type A is carried out in t days, then (8-t) days to produce type B, according to the meaning of the topic:, the solution is t=7, so the maximum value of x can only be, so the value range of x is;

To make y obtain the maximum value, because y = is a one-time function, the shirt collapses and y increases with the increase of x, so when x takes the maximum value, y takes the maximum value of 10,000 yuan), that is, arrange the production of type A 10,000, type B 10,000, so that the total profit obtained is the largest, the maximum profit is 10,000 yuan, if you want to complete the task in the shortest time, all the production of sail Li type B takes the shortest time, or car round.

However, in order to produce 10,000 type A, therefore, in addition to the production of 10,000 type A, the rest of the 10,000 should be changed to the production of type B, and the shortest time required is days).
