Introduce notation and write an expression to calculate the average productivity of the agri-cultural land in merced county as a double integral. specify the definition of the function tobe integrated and the domain over which it must be integrated. (you do not need to providea formula of the typef(x, y) =x2+y, rather just explain what the functions and variableswould stand for). 2. using iterated integrals, evaluate the volume above the triangle with vortices (0,0), (2, 1) and (3,0) (in the ry-plane) and below the surface z = 2xy. 3. sketch the region of integration and evaluate the iterated integral sl cos(2")dx dy jo j 1/3

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.

(x,y) it'll always be like that.

in this case x is grams and y is ounces.

if there were numbers there, like (5,3)

x would be 5 and y would be 3.
