Are these English sentences grammatically correct? If not, help me correct them
baby boy when i know
that our love has gone
raise my head to the sky
and can't stop my tear for you

baby boy when i got to know that our love has gone

and couln't shedding tears for you.

What's wrong with these English sentences?
Mike is a English boy.
Mr Jiang is not an Chinese teacher.
Spell"key",please.---Yes,K-E-Y
What's that for Chinese?

1. Mike is a English boy. A → an English starts with a vowel, so we have to use an2. Mr Jiang is not an Chinese teacher. An → a sentence in which the Chinese starts with a consonant, and A3. Spell "key", please. --- yes, k-e-y key is added before the word 4. Wh ·······································································

The monotone function f (x) defined on R satisfies f (- 3) = log2 (3) and f (x + y) = f (x) + F (y) for any XY belonging to R
(1) Judge the parity of function f (x) and prove it
(2) If the inequality f (2T-3T & # 178;) + F (T & # 178; - K) < 0 holds for any t ∈ (0,2), the value range of real number k can be obtained

(1) F (x) is an odd function
f(0+0)=f(0)+f(0)
F (0) = 0
Let y = - X,
F (0) = f (x) + F (- x)
f(-x)=-f(x)
F (x) is an odd function
(2)
∵ f (x) is a monotone function
-30=f(0)
∴f(-3)>f(0)
F (x) is a decreasing function
f（2t-3t²）+f（t²-k）＜0
f(2t-3t²)＜-f(t²-k)
F (x) is an odd function
∴f(2t-3t²)＜f(-t²+k)
∴2t-3t²>-t²+k
-2t²+2t>k
Let g (T) = - 2T & # 178; + 2T, t ∈ (0,2)
Symmetry axis t = 1 / 2
T = 2 is farthest from t = 1 / 2
The minimum value of G (T) = g (2) = - 8 + 4 = - 4
∵ t ∈ (0,2), less than 2
∴g(t)>-4
∴k≤-4
The value range of real number k is k ≤ - 4

Let XYZ be a three digit number with x > Z. if ABC = XYZ ZYX, then ABC + CBA=______ ．

Because ABC = XYZ ZYX, then ABC = (100x + 10Y + Z) - (100z + 10Y + x) = 99x-99z = 99 (x-z); and ABC is still a three digit number, so 99 < 99 (x-z) < 1000, x-z can take integer values 2, 3, 4, 5, 6, 7, 8. ABC can take values of 198297 The corresponding CBA is 891792 Then ABC + CBA = 198 + 891 = 297 + 792 = =1089, so the answer is: 1089

Let the random variable x obey the exponential distribution with parameter 3, and find the probability density function of the random variable y = 1-e ^ (- 3x)

Solution
 
Note: if x is a continuous random variable and f (x) is its distribution function, then x is a random variable
Y = f (x) must obey the uniform distribution on (0,1). & nbsp; it's better to remember this result. It's very convenient to do questions
For this problem, if you know that y = 1-e ^ (- 3x) obeys the uniform distribution on (0,1), then you have a goal

For example, the area of the large parallelogram in the figure is 48 square centimeters, and a and B are the middle points of the upper and lower sides. Can you find out the area of the small parallelogram (shadow part) in the figure?

Connect CD, the area of shadow is 48 △ 2 = 24 (square centimeter); answer: the area of small parallelogram (shadow) is 24 square centimeter

How to transform the general form of quadratic function into vertex form and double radical form, how to transform the vertex form and double radical form of quadratic function into general form

To convert the general formula of quadratic function into vertex formula, use formula method, such as y = x ^ 2 + 4x-3 = (x ^ 2 + 4x + 4) - 7 = (x + 2) ^ 2-7, to convert the general formula of quadratic function into double radical formula is factorization, such as y = x ^ 2-3x + 2 = (x-1) (X-2), to convert the vertex formula and double radical formula of quadratic function into general formula, and expand them directly, such as y = (x-3)
