<span>A Smart Card refers to the integrated circuit chip on the card - that's the small square or round chip usually seen on the face of the card. This is used on both debit and credit cards to deliver encrypted authentication for the card when it is used in an shop at an electronic data capture machine (POS terminal), or at an ATM. The chip helps to prevent fraud and reduces the risk of a card’s data being duplicated.</span>

Which expression is equivalent to [(3xy^-5)^3/(x^-2y^2)^-4]^-2?

Mademuasel [1]

Answer:- a.The given expression is equivalent to $\frac{x^{10}y^{14}}{729}$

Given expression:- $[\frac{(3xy^{-5})^3}{(x^{-2}y^2)^{-4}}]^{-2}$

$=[\frac{(3)^3x^3y^{-5\times3}}{x^{-2\times-4}y^{2\times-4}}]^{-2}.........(a^m)^n=a^{mn}$

$=[\frac{27x^3y^{-15}}{x^8y^{-8}}]^{-2}$

$=[27x^{3-8}y^{-15-(-8)}]^{-2}............\frac{a^m}{a^n}=a^{m-n}$

$=[27x^{-5}y^{-7}]^{-2}=(27)^{-2}(x^{-5})^{-2}(y^{-7})^{-2}.........(a^m)^n=a^{mn}$

$=\frac{1}{(27)^2}(x^{10}y^{14})=\frac{x^{10}y^{14}}{729}$

Thus a. is the right answer.

HELP ME PLEASE <br><br> 58.25 is an irrational number. True or false?

Aneli [31]

Irrational numbers don't end
they can't be written in form a/b

obvoisly, 58.25 ends and it can be written as 58.25/1

(repeating decimals can be written in a/b form, it just takes work to find)

false, 58.25 is NOT irrational

5. The rate of change in revenue for the Priceline Group from 2004 to 2013 can be modeled

Mumz [18]

Answer:

a ) R(x) = 0,2933*e∧0,2387*t

b) 5,9042 billions of dollars

Step-by-step explanation:

The rate of change in revenue dR/dt for Priceline Group is

dR/dt = 0,07*e∧0,2387*t

dR = (0,07*e∧0,2387*t ) * dt

∫dR = ∫ (0,07*e∧0,2387*t ) * dt between 2004 to 2013 ( t = 4 stands for 2004 and t = 13 stands for 2013 )

R(x) = (0,07/ 0,2387)*e∧0,2387*t )

R(x) = 0,2933*e∧0,2387*t

Then

R(4) = 0,2933*e∧0,2387*4

R(4) = 0,2933*2,5981

R(4) = 0,7602 billions of dollars

R(12) = R(4) + 0,2933*e∧0,2387*12

R(12) = 0,7602 + 5,1440

R(12) = 5,9042 billions of dollars
