3) g(x)= x3 + x h(x) = x + 4 Find g(0)h(0)

Arte-miy333 [17]

Answer:

$goh(x)=x^3+12x^2+49x+68$

Step-by-step explanation:

$g(x) = x^3+x$

$h(x)=x+4$

We have to find

$goh(x)$

$goh(x) = g(h(x))=g(x+4)$

If $g(x) = x^3+x$

$g(x+4) = (x+4)^3+(x+4)$

= $x^3+12x^2+49x+68$

Hence our answer is

$goh(x)=x^3+12x^2+49x+68$

What is the volume of this sphere?

Natasha_Volkova [10]

Answer:

Option c. 11,488.21 cm3

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The volume of the sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

we have

$r=28/2=14\ cm$ ---> the radius is half the diameter

$\pi =3.14$

substitute

$V=\frac{4}{3}(3.14)(14)^{3}$

$V=11,488.21\ cm^3$
