Determine if the statements below are true or false. (a) if f · da s = 12 and s is a flat disk of area 4π, then divf = 3 π . true false (b) if f is a vector field in 3-space, then grad(divf) = 0 i + 0 j + 0 k true false (c) if s is the unit sphere oriented outward and f is a vector field satisfying f · da s = 0 , then divf = 0 at all points inside s.

the f

last graph i believe

step-by-step explanation:

worked it out i believe

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
