Zhu plans to process an average of 93 machine parts per day in six days. If he processes another day, his average number of machine parts per day will become 91
How many are processed on the seventh day?
Suppose processing x on the seventh day
93*6+x=91*7
558+x=637
x=79
It is known that the perimeter of RT △ ABC is 12, and a right angle side is 4, then s △ ABC=______ ．
Let the length of the other right angle side be X. then the hypotenuse is 12-4-x = 8-x42 + x2 = (8-x) 2, and the solution is x = 3 s △ ABC = 12 × 4 × 3 = 6
Given that P is a prime number, it is proved that there must be p numbers in any 2p-1 integers, and the sum of which is divisible by P
Look at the graph. Change p to n
(tan10°−3)sin40°=______ ．
(tan10 °− 3) sin40 ° = (sin10 ° cos10 °− 3) sin40 ° = sin10 °− 3cos10 ° cos10 °× sin40 ° = 212sin10 °− & nbsp; 32cos10 ° cos10 °× sin40 ° = 2Sin (10 °− & nbsp; 60 °) cos10 °× sin40 ° = - 2sin50 ° cos10 °× sin40 ° = - sin80 ° cos10 ° = - 1
Given that f (x) = LG (- x2 + 8x-7) is an increasing function on (m, M + 1), then the range of M is______ ．
The domain of definition (1,7) ∵ f (x) = LG (- x2 + 8x-7) is an increasing function on (m, M + 1). From the monotonicity of the composite function, it can be seen that t = - x2 + 8x-7 is monotonically increasing on (m, M + 1) and t > 0. The increasing interval (1,4) and decreasing interval [4,7) m ≥ 1m + 1 ≤ 4 & nbsp; 1 ≤ m ≤ 3 of the function, so the answer is: 1 ≤ m ≤ 3
Fill in the brackets with the appropriate prime number 36 = () times () times () times ()
There's another one
49=（ ）+（ ）+（ ）+（ ）
36 = (2) multiply (2) multiply (3) multiply (3), 49 = (2) + (3) + (3) + (41) or 49 = (2) + (3) + (7) + (37), 49 = (2) + (5) + (11) + (31), 49 = (2) + (7) + (11) + (29), 49 = (2) + (5) + (19) + (23), 49 = (2) + (7) +
Given that the probability density of continuous random variable x is FX (x) and y = 2x, then the probability density of Y is FY (y)=
To detailed steps, thank you!
Given the quadratic function f (x) = ax ^ 2 + BX + C, the equation f (x + 1) = f (x) + X + 1 holds. If f (- 1) = - 1, find the expression of F (x)
As a result, we will be able to (x + 1) as (x + 1) \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\/ 2 + X / 2 -
What is the greatest common factor of 13 and 7?
13 and 7 are prime numbers, except 1 and it can't be divisible by other numbers
