(1 point) Let f(x, y)=xex2−yf(x, y)=xex2−y and P=(6,36)P=(6,36). (a) Calculate ∥∇fP∥‖∇fP‖. (b) Find the rate of change of ff in the direction ∇fP∇fP. (c) Find the rate of change of ff in the direction of a vector making an angle of 45∘45∘ with ∇fP∇fP. Answers : (a) (b) (c)

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
