The table below shows the value of Henry's car at the end for each of the first 3 years after it is purchased. The values form a

SVETLANKA909090 [29]

Using a geometric sequence, it is found that the approximate value of the car at the end of the 10th year will be given by:

A. $6,974.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

$a_n = a_1q^{n-1}$

In which $a_1$ is the first term.

In this problem, the first term and the common ratio are given, respectively, by:

$a_1 = 18000, q = \frac{16200}{18000} = 0.9$

Hence the equation is:

$a_n = 18000(0.9)^{n-1}$

At the end of the 10th year, the value will be of:

$a_{10} = 18000(0.9)^{10-1} = 6974$

Hence option A is correct.

What are the zeroes of f(x) = x2 − x − 2? (4 points) a x = −2, 1 b x = 2, −1 c x = −2, −1 d x = 2, 1

Korvikt [17]

Answer:

x=2, x=-1

Step-by-step explanation:

f(x) = x^2 − x − 2

Set equal to zero

0 = x^2 − x − 2

Factor

What 2 numbers multiply to -2 and add to -1

-2*1 = -2

-2+1 =1

0=(x-2) (x+1)

Using the zero product property

x-2 =0 x+1 =0

x=2 x=-1

The numbering system we commonly use is called the decimal numbering system because it uses ____ symbols to represent all possib

mafiozo [28]

The numbering system we commonly use is called the decimal numbering system because it uses 10 symbols to represent all possible numbers.

A way of writing numbers is known as a number system.

There are the following number systems:

Decimal number system: "Deci" meaning 10, implies that the number system consists of 10 digits or symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
Binary number system: "Bi" meaning 2, implies that the number system consists of 2digits or symbols, namely 0, and 1.
Octal number system: "Oct" meaning 8, implies that the number system consists of 8 digits or symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, and 8.
Hexa-Decimal number system: "Hexa-Deci" meaning 16, implies that the number system consists of 16 symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.

Hence, we can say that the numbering system we commonly use is called the decimal numbering system because it uses 10 symbols to represent all possible numbers.
