Use differentials to estimate the amount of paint needed to apply a coat of paint 0.07 cm thick to a hemispherical dome with dia

Sav [38]

Answer:

10.12 $m^{3}$

Step-by-step explanation:

Given:

0.07 cm thick = 0.007m and it is dr (the change in radius)

As we know that, the volume of a hemispherical dome with diameter 48 m is:

V = $\frac{2}{3}$ π $r^{3}$

Take the derivative of V we have:

$\frac{dV}{dr}$ = 2π $r^{2}$

<=> dV = 2π $r^{2}$ *dr

<=> dV = 2π* $48^{2}$ *0.0007 = 10.12 $m^{3}$

Hope it will find you well.

Determine whether the given function is a polynomial function. If it's a polynomial function, state the degree. If not, state th

Rudik [331]

ANSWER

The correct answer is option D.

EXPLANATION

The given function is

$k(x)=-3x^6-0.7x+x^3$

This a polynomial function. All degrees are greater than or equal to zero.

The coefficient being decimals does not disqualify it from being a polynomial.

The highest degree of this polynomial is 6.

Therefore the correct answer is D
