Answer:

$(m^{4} + 5) - n^{3}$ = 85

Step-by-step explanation:

$(m^{4} + 5) - n^{3}$ given m = - 2, and n = -4

Substitute the given values into the polynomial expression:

$(m^{4} + 5) - n^{3}$

$[(-2)^{4} + 5] - (-4)^{3}$

= (16 + 5) - (-64)

= 21 + 64

= 85

Therefore, the correct answer is 85.

An engine cylinder 13.7 cm deep is being bored such that the radius increases by 0.13 mm divided by min. How fast is the volume

zzz [600]

Answer:

Step-by-step explanation:

Given that an engine cylinder 13.7 cm deep is being bored such that the radius increases by 0.13 mm divided by min.

We convert everything in mm for uniformity

We have formula for volume as

$V=\pi r^2 h$

Given that $\frac{dr}{dt} =0.13$

h is constant

$V= 3.14 (r^2) (13.7)\\\frac{dV}{dt} =6.28 (137) r dr/dt\\= 6.28(137)\frac{ (97)}{2} 0.13$

= 6954.67 mm/sec^3
