For each of the following vector fields f, decide whether it is conservative or not by computing the appropriate first order partial derivatives. type in a potential function f (that is, nabla f = f) with f(0,0) = 0. if it is not conservative, type n. a f (x, y) = (6x - 2y)i + (-2x + 8y)j f (x, y) = b. f (x, y) = 3yi + 4xj f (x, y) = n c. f (x, y) -= (3siny)i + (-4y + 3x cosy)j f(x, y) =

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

nope.   happens to me as well.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
