Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $24 monthly fee

JulsSmile [24]

Answer:

600 minutes

Step-by-step explanation:

If we write both situations as an equation, we get:

y1 = 24 + 0.15x

y1 : total cost paid in first plan

x : total minutes of calls

y2 = 0.19x

y2 : total cost in second plan

x: total minutes of call

We are now looking for the situation where the total cost in the two plans is equal, so

y1 = y2

this gives

24 + 0.15x = 0.19x

<=> 0.04x = 24

<=> x = 600

Find derivative of y=(-3x^5+1)^3

sattari [20]

Use the chain rule:

$\frac{\mathrm dy}{\mathrm dx}=3(-3x^5+1)^2\frac{\mathrm d[-3x^5+1]}{\mathrm dx}=3(-3x^5+1)^2(-15x^4)=\boxed{-45x^4(1-3x^5)^2}$

Dati gli insiemi A(1,2,3,4,5) B(3,4,5,6,7) C(2,4,6,8) calcola il risultato della seguente espressione: (A∩B)∩C

Oduvanchick [21]

Answer:

(4)

Step-by-step explanation:

L'intersezione si occupa di elementi comuni

segno per intersezione = ∩

A = (1,2,3,4,5)

B = (3,4,5,6,7)

C = (2,4,6,8)

(A∩B)∩C

(A∩B) = (3, 4, 5)

(A∩B)∩C = (4)
