It would be: -2/3 * -9/10 = 18/30 = 3/5
So, option B is your answer.
Hope this helps!
The volume of the sphere is expressed in the formula V = 4/3 pi r^3. The rate of change of volume is determined by differentiating the formula: dV/dt = 4pi r^2 dr/dt. When we substitute 500 cm3/min as dV/dt and 30 cm as r. Then dr/dt is equal to 0.0442 cm/min
Divide both by 18.
<span>140/18=7.78 </span>
<span>So... $7.78 per foot</span>
Find common factor, in this case the common factor is 10x
So the answer would be 10x(x^6 - y^10)
47.60514678
What I did was 28 squared plus b squared equals 38.25 squared and ya......
