ANSWER:

A is number 3

B is number 2

Step-by-step explanation:

The left side is A and B (order)

the right side is 1,2,3,4 (order)

explanation: A is number 3 because as said in A the tram already has 5 people which is what we start with a1 = 5 and we add 11 at each stop as shown in the equation.

B is number 2 for the same reason as it started with 2 but added 4 inches of rain each time.

Answer: $\Large\boxed{Fourth~Choice.~f(x)=2-i}$

Concept:

Here, we need to know the power of imaginary numbers

i = √(-1)

i² = -1

i³ = -i

i⁴ = 1

Solve:

Given function expression

$f(x)=x^3-2x^2$

Given the requirement of the question

To find the expression for f(i)

Substitute values into the expression

$f(x)=(i)^3-2(i)^2$

Simplify the exponents

$f(x)=(-i)-2(-1)$

Expand the parenthesis

$f(x)=-i-(-2)$

$\Large\boxed{f(x)=2-i}$

Hope this helps!! :)

Answer:

La respuesta correcta es la opción d) 5 a 1.

Step-by-step explanation:

Para calcular la relación entre los ingresos de Mary en 2019 ( $I_{2019}$ ) con respecto a sus ingresos en 2018 ( $I_{2018}$ ), partimos de que los ingresos de Mary en 2019 fueron un 20% mayores que sus ingresos en 2018:

$I_{2019} = 20\% \: I_{2018}$

$I_{2019} = \frac{20}{100}I_{2018}$

$\frac{100}{20}I_{2019} = I_{2018}$

$5I_{2019} = I_{2018}$

Entonces, la relación entre los ingresos de Mary en 2019 es 5 veces los ingresos de Mary en 2018. Por lo tanto, la respuesta correcta es la opción d) 5 a 1.
