(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)

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

answer: h

step-by-step explanation:

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
