The function f(x, y)=xy(1−10x−4y) has 4 critical points. List them and select the type of critical point. Points should be given as ordered pairs and listed in increasing lexicographic order. By that we mean that (x, y)(x, y) comes before (z, w)(z, w) if x < zx < z or if y< wy< w. 

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.

you already gave the answer

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

27 +27 or 27times 2=54

the diffrence is 0
