Does anyone know these questions? Does anyone know how to do this?

I think if you don't know how to do these questions, you can ask your teacher for advice, or talk to your classmates.

A few questions will definitely be asked, if you want to ask professional talents, it will be explained more clearly.

These questions must be done by everyone, so everyone will know how to solve these problems after doing these questions.

I'm sorry, I can't open this question, I can't see if this question will be played, you should ask your teacher. The teacher will definitely give you the answer.

Will any of these do? I'm not very good at remembering this specifically, so I want to ask the students.

If you don't know, I can ask your teacher directly if you don't know, and your teacher will answer it for you in detail.

You can find a professional to solve it, or find a relevant teacher to talk to you.

I've always thought that these questions are more complex than the masters.

I don't know how to do it myself, so I suggest you go to some professional question banks to see if you can help you solve it.

Does anyone know these questions, then I don't know if others say they will?

Do you know how to do it, I don't know how to do it anyway You can consult others again to see if anyone can do this question.

As shown in the figure below, the Vedic theorem of binary linear equations is mainly used, and when =0, there is only one solution, that is, only one intersection.

Is the one in the middle an equal sign? Then f(x+1)=(x+1-1)(x+1), so f(x)=x(x-1), and therefore f(2)=2

This is a simple commutation, and the answer is 2

There is a question, is it an equal sign or a minus.

The title says that rachel's purpose is to maximize the utility (function) of her build, and you can give an example of how she swapped apples and bananas. If the constructed utility function is the product of the number of apples and the number of bananas, i.e. the function u(a,b)=ab where a,b are the number of apples and the number of bananas, respectively.

Since a+b=12, b=12-a, substituting the function yields:

u=a(12-a)=12a-a^2=-(a^2-12a+36)+36=-(a-6)^2+36

It can be seen that the function is a parabola with vertices of (6,36), and the maximum value of u is 36 when a takes 6

a=6, b=12-a=6, i.e., when both apples and bananas are swapped for 6, her objective function value is the largest, and the maximum value is 36.

Find the open-circuit voltage UAB=4*ix, and the short-circuit current isFinding the open-circuit voltage, the kvl of the column loop, the following equation can be obtained.

ix=4 3, so uab=4*ix=16 3, find the short-circuit current, directly short-circuit the 4 resistor, and then use the above equation, at this time, remove the last term, and replace ix with is, you can get is=12. Rab=uab is=1 9 is obtained, so the Thevenant equivalent circuit is the voltage source 16 3(V) connected in series with the resistance Rab=1 9(.

1) Set up a type x class and b type y class.

From this: x+y=17 80x+60y=1220 is obtained: x=10 y=7

2) The second question does not need to be calculated, according to common sense, the smaller the x, the better, but it should still be greater than y, so x=9 y=8

——New Dynamics International English, we are not only good at English, we also teach mathematics as long as you want to learn!!

There are A X classes and B Y classes.

From this: x+y=17 80x+60y=1220 is obtained: x=10 y=7

2)x>17-x

x > round 9

So the x maximum is 9 y=8
