Please help The question is as follows, please help with a question, as follows

If you just write the answers, I don't think it will help you learn math. But you don't know how to do this question, if I were next to you, I would have guided you directly, instead of writing the answer. If you have a way, I'll tell you the way (for reference only, if you are satisfied):

Solution: p q is false, p q is true, p and q must have one true and one false. Let g(x)=ax -ax+1, which is divided into the following three cases:

When a=0, g(x)=1>0 is true by bringing into the g(x) and f(x) equations, respectively, and p is true. f(x)=x -3, so that f(x)>0 gives x (-3) (3,+ contradicts the proposition q, q is false, i.e., a=0 satisfies the proposition.

When a>0, p true q false] parabola g(x) opening upward, to make p a true proposition, then there must be =a(a-4)<0, get a (0,4), then q must be false, the parabola f(x) opening upward, because a>0 knows that the axis of symmetry is on the positive half axis of the x-axis, and =2a+3>0 is obviously true, the parabola f(x) and the x-axis must have two intersections, so that x=-1, f(-1)=1+a+a -2a-3 0 (at this time, if f(x)>0 then the condition of "[-1,0] makes f(x)>0 true"), a [-1,2] makes q false, and the intersection gives a (0,2] satisfies the topic.

p false q true] is the opposite of the above characteristics, in the same way, from the parabola g(x) to get a [4,+ makes p false, from the parabola f(x) to get a (2,+ makes q true, take the intersection to get a [4,+ satisfies the topic.

Then take and merge a (0,2] [4,+.]

When a<0, the parabola g(x) opening downward, p must be false, q must be true, the direction of the parabola f(x) opening is unchanged, the axis of symmetry is on the negative half axis of the x-axis, when =2a+3>0, a (-3 2,0), the parabola f(x) and the x-axis have two intersection points, so that x=0, f(0)=a -2a-3>0, get a (-1);

When =2a+3<0, a (-3 2) is also a true proposition, and a (-1) is obtained by taking and summing it

To sum up, taking and summing all cases yields a (-1) [0,2] [4,+, which is the range of values of the real number a.

Well, it won't! It takes a math expert to figure it out.

p:00;When the axis of symmetry is 0, f(0)>0You can divide it into two situations: p, false, q, true, p, false, and if you have any doubts, you can ask again.

Problem description: The loss in the first and second quarters is 30,000, and the profit in the third quarter is 10,000, do you pay corporate income tax in the third quarter? Please explain why, the more detailed the better, thank you all in advance :)

Analysis: According to the provisions of the tax law, the enterprise income tax is levied on an annual basis and paid in advance on a monthly basis (rotten season). Monthly (quarterly) tax prepaid = Cumulative taxable income from the beginning of the year * Tax rate - Income tax paid in advance for the current year.

Therefore, if the enterprise in the question has no unmade loss-making land loss at the beginning of the year (loss and rent ridge under the tax law), and the "profit" and "loss" referred to in the question are both tax law concepts (i.e., there are no other tax adjustments), then:

The cumulative taxable income in the third quarter = 1 + 3) = 20,000 yuan, which is a loss and does not need to pay enterprise income tax in advance.

Matters that should be paid attention to in the collection and production of plant leaf specimens.

When collecting, ensure that the leaves are intact and not damaged.

Use tweezers to avoid fingerprints and stains.

In addition to collecting and producing plant specimens, what other means are used to understand and study plant characteristics and provide a basis for identifying plant species?

Observing, documenting, and hand-growing plants is the best way to do research.

Burn seedlings"The main reason? How to alleviate "burning seedlings"?

Excessive fertilization can lead to a high concentration of soil solution and a high osmotic pressure.

The roots of the plant cannot absorb water, and the plant wilts without water, which is the burning of seedlings.

To slow down the burning of seedlings, water more.

Take a radish, select a part and cut it into three parts, A cup of water, B cup of salt water, C cup empty, one hour, test the hardness.

1 .How does the radish in cup A change compared to the radish strips in cup C? What does that mean?

C can be compared to A, the cells of A, swell, harden because the osmotic pressure of water is less than the cytoplasm inside the cell.

2.How does the radish in cup A change compared to the radish strips in cup B? What does that mean?

Compared with B, it can be compared that the Etocytes shrink, soften and cause plasmoplasm wall separation, because the osmotic pressure of saline water loss is greater than that of the cytoplasm in the cell.

Only C remains the same in the whole process, I hope it can help you.

1 Ink diffusion is slower in cold water.

2 Ink diffusion in hot water is faster.

When the temperature is high, the molecules move vigorously.

3 Suddenly, the red ink in the vial was like a volcanic eruption, and the mouth of the bottle spewed out a cloud of red smoke, swirling and rising, which was very beautiful

The density of the temperature changes, the higher the temperature, the smaller the density (except for 1 4 degrees), the density of hot water in the small bottle is less than the cold water in the large glass, so there is the above phenomenon. (This is the explanation of junior high school), in terms of molecular thermal motion: temperature is the average speed of molecules, and the average speed of hot water molecules is fast, so the above phenomenon occurs when more hot water molecules enter the large glass per unit time.

1. Sales revenue 40,000 * (1-10%) 36,000 (yuan) cash discount 36,000 * 10% 3,600 (yuan) sales: debit: accounts receivable 42,800

Credit: main business income 36000

Tax Payable VAT payable (output tax) 6800

Cash Receipt: Borrow: Bank Deposit 39200

Finance Fee 3600

Credit: Accounts receivable 42800

2. Revenue expenditure is d, and the first three are capital expenditures.

3. It is an accounting period.

I don't know if you're satisfied.

1 Debit: Accounts receivable 42120

Credit: main business income 40 000 * 000

Tax payable - VAT payable (output tax) 36 000 * debit: bank deposit 40320

Finance costs 36,000*

Credit: Accounts receivable 42120

I'm also a beginner, we just learned receivables and prepayments there, 2, 3 I won't, I don't know so I don't dare to tell you, but I just learned cash discounts, we can ** a little,

The length of the New York Bridge is x, the length of the Nanjing Yangtze River Bridge is (x+4570) meters, and the length of the Wuhan Yangtze River Bridge is (x-530) meters.

x+4570+x-530+x=10640

x=2200

Therefore, the New York Bridge is 2200 meters long, the Nanjing Yangtze River Bridge is 2200 + 4570 = 6770 meters long, and the Wuhan Yangtze River Bridge is 2200-530 = 1670 meters long.
