Acube with edges of length x centimeters has volume v(x)=x^3 at the instant when x=2, what is the rate of change of x, in centimeters per minute, with respect to time?

The rate of change of x, in centimeters per minute, with respect to time is found to be :

Step-by-step explanation:

Edge length of the cube is given to be x centimeters

Hence, the rate of change of x, in centimeters per minute, with respect to time is found to be :

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
