What is the domain of f(x) = 2^x?
hammer [34]

The given function has no undefined points nor domain constraint. Thus, the domain is: -\infty \: < x < \infty.

<h3>Domain and Range</h3>

The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. An example, there is a restriction for the domain of fractions. The variable x in the denominator should be different of zero.

While the domain is related to the values ​​of x, the range is related to the possible values ​​of y that the function can have.

In this question, the function 2^x has no undefined points nor domain constraint. Therefore, the domain is: -\infty \: < x < \infty

Fernando wants to purchase a new laptop for 2323000 columbian pesos. the electronic store has a financing offer. Fernando pays t
Nesterboy [21]

Answer:

i) 3.38%

ii) 23846 pesos

Step-by-step explanation:

The formula for Simple Interest =

Principal × Rate × Time

Simple Interest is calculated as:

Amount(after t years) - Principal(initial amount

From the question,

Amount = 2480000 pesos

Principal = 2323000 pesos

Simple Interest = (2480000 - 2323000)pesos

= 157000 pesos

i. What is the simple interest rate the electronics store is charging if he ends up paying it 2480000 pesos in total?

This means we are to find r, hence:

Simple Interest = Principal × Rate × Time

Time = 2 years

157,000= 2323000 × R × 2

R = 157,000/2323000 × 2

R = 157,000/4646000

R = 0.03379250968

Simple Interest rate = 0.03379250968

Converting to percentage

= 3.379250968%

≈ Approximately 3.38%

ii. How much is weekly payment to the electronics store? Round your answer to the nearest Peso.

We are told in the question that:

Fernando pays the electronic store in weekly installments over two years.

52 weeks = 1 year

Hences

2 years = 52 × 2 = 104 weeks

Weekly payments = 2480000 pesos/104 weeks

= 23846.1538462 pesos

Approximately to the nearest peso = 23846 pesos
