Question

Please need help I will be MARKING as BRIANILIST. thank you so much. ​​

Answer 1

Answer:C.8.027

Step-by-step

V = s$^{3}$

The rate of change is found using the first derivative of this function. This is often called the gradient function, because it gives the gradient of a tangent line drawn at the specified point.

$\frac{dV}{ds}$(s$^{3}$) =3s$^{2}$

We now plug in  s =6

3s$^{2}$ = 3(6)$^{2}$ = 8.027$\frac{cm3}{s}$

Answer 2

Answer:

12.167(option D)

Solution,

$side \: length(s) = 2.3 \\ volume = {s}^{3} \\ \: \: \: \: \: \: \: \: \: \: = {(2.3)}^{3} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 2.3 \times 2.3 \times 2.3 \\ \: \: \: \: \: \: \: \: = 12.167 \: {cm}^{3}$

hope it helps...

Good luck on your assignment....
