Data organization and analysis are done through a method of classifying and organizing data according to its category and how it's analyzed. One of the examples of data organization and analysis is a. Drawing a pie chart to show the percentage of sunny days, rainy days and cloudy days without percipitation - in this example, the data organization is done through charts and graphs, wherein the classification of data is visually available. Another example is e. Summing the number of days with precipitation, summing the number of sunny days, and summing the number of cloudy days without percipitation - in this example, the data organization is done through summation of numbers only and no graphs or charts to visually present the data.

Algebraically find the inverse of a function

Savatey [412]

Answer:

1) f⁻¹(x) = 6 ± 2√(x -1)

3) y = (x +4)² -2

5) y = (x -4)³ -4

Step-by-step explanation:

In general, swap x and y, then solve for y. Quadratics, as in the first problem, do not have an inverse function: the inverse relation is double-valued, unless the domain is restricted. Here, we're just going to consider these to be "solve for ..." problems, without too much concern for domain or range.

1) x = f(y)

x = (1/4)(y -6)² +1

4(x -1) = (y-6)² . . . . . . subtract 1, multiply by 4

±2√(x -1) = y -6 . . . . square root

y = 6 ± 2√(x -1) . . . . inverse relation

f⁻¹(x) = 6 ± 2√(x -1) . . . . in functional form

3) x = √(y +2) -4

x +4 = √(y +2) . . . . add 4

(x +4)² = y +2 . . . . square both sides

y = (x +4)² -2 . . . . . subtract 2

5) x = ∛(y +4) +4

x -4 = ∛(y +4) . . . . . subtract 4

(x -4)³ = y +4 . . . . . cube both sides

y = (x -4)³ -4 . . . . . . subtract 4

Okay I don't understand how do I do this. It say :

Lilit [14]

2x+3=17

subtract 3 from each side

2x+3 -3 = 17 -3

2x = 14

divide by 2 on each side

2x/2 = 14/2

x = 7

A newspaper advertisement offers a $6500 used car for nothing down and 36 easy monthly payments of

NNADVOKAT [17]

Using simple interest, it is found that:

The total amount paid was of $7,084.8.

The finance charge was of $584.8.

The simple interest rate was of 3%.

<h3>Simple Interest</h3>

Simple interest is used when there is a single compounding per time period.

The amount of interest after t years in is modeled by:

$I = Prt$

In which:

P is the initial amount.

r is the interest rate, as a decimal.

In this problem, the amount paid was of 36 monthly payments of

$196.80, hence:

36 x 196.80 = $7084.8.

The total amount paid was of $7,084.8.

The original price is of $6,500, hence the finance charge was of:

7084.8 - 6500 = $584.8.

For interest, we have that:

$I = 584.8, P = 6500, t = 3$ , hence:

$I = Prt$

$584.8 = 6500(3)r$

$r = \frac{584.8}{6500 \times 3}$

$r = 0.03$

The simple interest rate was of 3%.
