serious [3.7K]

Answer:

$1200.

Step-by-step explanation:

We have been given that Kiersten runs a website that helps people learn programming. Every month, Kiersten receives a subscription fee of $10 from each of the subscribers to her website.

First of all we will find the number of subscribers for this month.

$\text{Total number of subscribers this month}=100+30-10$

$\text{Total number of subscribers this month}=130-10=120$

Now let us multiply number of total subscribers of this month by 10 to find the amount Kiersten will earn by her online business.

$\text{Kiersten's earnings this month from online business}=120*10$

$\text{Kiersten's earnings this month from online business}=1200$

Therefore, Kiersten will earn $1200 this month by her online business.

Use spherical coordinates to find the limit. [Hint: Let x = rho sin(ϕ) cos(θ), y = rho sin(ϕ) sin(θ), and z = rho cos(ϕ), and no

shutvik [7]

Answer:

lim (x, y, z) → (0, 0, 0) [x*y*z]/(x^2+y^2+z^2)=0

Step-by-step explanation:

First, we need to put the spherical coordinates equations that we will use in our problem

x = p*sin∅cos Ф

y = p*sin∅sinФ

z=p*cos∅

Then we will state the problem

lim (x, y, z) → (0, 0, 0) [x*y*z]/(x^2+y^2+z^2)

Using the spherical coordinates we get

(x^2+y^2+z^2) = p^2

Which will make our limit be

lim p→0+ [p*sin∅cos Ф*p*sin∅sinФ *p*cos∅]/(x^2+y^2+z^2)

after solving limit:

lim (x, y, z) → (0, 0, 0) [x*y*z]/(x^2+y^2+z^2)=0
