Nail a parallelogram with a length of 15 cm at the bottom and a height of 6 cm. After piling it up into a rectangle, the area increases by 45 square cm. Find the perimeter of the rectangle

15*6=90
90+45=135
135/15=9
15 * 2 + 9 * 2 = 48 cm

The intersection of function y = - 4-2x and function y = 3x + B is in the third quadrant, and the value range of B is obtained

y=-4-2x=3x+b
5x=-4-b
x=(-4-b)/5
y=-4-2x=-4-2(-4-b)/5
Quadrant 3 x

The partial derivative of binary function z = f (x, y) with respect to X is generally a: function with respect to x B: function with respect to Y C: function with respect to x, y d: a real number

Choosing C and finding partial derivative of X is equivalent to taking y as a constant and finding derivative of X, but the expression still contains y

As shown in the figure, the blank part is a square. Please use letters to indicate the area of the blank part and the shaded part respectively. (length unit: cm)

A × B-B × B = ab-b2 (square centimeter). A: the area of shadow is ab-b2 square centimeter

Given that f (x) is a quadratic function, if f (0) = 0 and f (x + 1) = f (x) + X + 1, find the expression of F (x)

Let f (x) = ax & sup2; + BX + C
∵f(0)=0
∴c=0
∴f(x)=ax²+bx
f（x+1)=a(x+1)²+b(x+1)
=ax²+2ax+a+bx+b
=ax²+(2a+b)x+a+b
=f（x）+x+1
∴ax²+(2a+b)x+a+b=ax²+bx+x+1
ax²+(2a+b)x+a+b=ax²+(b+1)x+1
∴2a+b=b+1
a+b=1
∴a=1/2
b=1/2
∴f(x)=1/2x²+1/2x

Given the set M = {YLY = x & # 178; - 4x + 3, X ∈ r}, n = {YLY = - X & # 178; + 2x + 8, X ∈ r}, find m ∩ n

M = {y l y = x² - 4x + 3,x∈R} = {y l y = (x - 2)² - 1,x∈R} = [-1 ,+∞)
N = {y l y = -x² + 2x + 8,x∈R} = {y l y = - (x - 1)² + 9 ,x∈R} = (-∞ ,9]
M ∩ N = [-1 ,9]

(a4-b4) / (A2 + B2) / (a + b) is calculated by multiplication formula

The original formula = (A & # 178; + B & # 178;) (a + b) (a-b) / (A & # 178; B & # 178;) / (a + b)
=a-b
