1. [12pts] Let LaTeX: \mathcal TT be the triangular region in the LaTeX: xyx y-plane with vertices LaTeX: (0,0), (m,0), (m, n) ,( 0 , 0 ) , ( m , 0 ) , ( m , n ) , where LaTeX: m, nm , n are positive constants. Use a double integral in polar coordinates to calculate the average value of the LaTeX: xx-coordinate, taken over all points in LaTeX: \mathcal T T. You may assume the formula for the area of the triangle.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the 3rd on is correct
