Assume c is a circle centered at the origin, oriented counterclockwise, that encloses disk r in the plane. complete the following steps for the vector field bold upper fequalsleft angle 7 x superscript 5 baseline y comma xy superscript 4 baseline plus 6 x superscript 6 right angle. a. calculate the two-dimensional curl of bold upper f. b. calculate the two-dimensional divergence of bold upper f. c. is bold upper f irrotational on r? d. is bold upper f source free on r?

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
