Computers depreciate rapidly. If a new computer that costs $1200 loses 40% of its value every year, what is its worth 5 years from now?

Answer:

Third choice: (1, -3); (2, 2); (3, 7)

Step-by-step explanation:

There are two ways to solve this

The easiest way to solve this is to understand that the inverse of a function f(x), denoted by f⁻¹(x) is nothing but a reflection of the function about the line y = x

What that means is that if (x, y) is a specific point on the line, then the inverse point will be (y, x). Basically we are swapping the x, y values

The 3 points on f(x) and the corresponding points on f⁻¹(x) are given below:

f(x)                f⁻¹(x)
------             --------
(-3, 1)             (1, -3)
(2, 2)             (2, 2)
(7, 3)             (3, 7)

From the options given we see that the 3rd choice gives the correct values

So answer:
Third choice: (1, -3); (2, 2); (3, 7)

The best interpretation of 14.2 as shown in the equation above is the constant acceleration of the airplane.

A particle's acceleration is the rate at which its velocity changes over time. The term "constant acceleration" refers to the rate at which a particle's velocity changes. When acceleration is constant, the rate of change in velocity is also constant. In the absence of any acceleration, velocity remains constant.

When acceleration is positive, velocity becomes more significant. Acceleration causes a decrease in velocity. The value 14.2 in the equation above represents the constant acceleration of the airplane in meters per second squared (m/s^2). It is the rate at which the velocity of the airplane is changing with respect to time.

The required simple interest would be the amount of 1,170€ on a 4500€ principal deposited for four years at a rate of 6.5%

We have been given data as:

Principal (P) = 4500€

Rate of Interest (R) = 6.5% = 6.5/100 = 0.065

Time (T) = 4 years

⇒ Simple interest  = P × R × T

Substitute the value of P, R, and T in the above formula,

⇒ Simple interest  = 4500 × 6.5% × 4

⇒ Simple interest  = 4500 × 6.5/100 × 4

⇒ Simple interest  = 4500 × 0.065 × 4

Apply the multiplication operation, and we get

⇒ Simple interest  = 1,170€

Therefore, the required simple interest would be the amount of 1,170€.

The coordinates of B, C, and D are (3,-5), (3,5), and (-7,5) respectively.

Given point A (-2,-5) and the lengths of the sides AB = 5 and BC = 10, we can use this information to determine the coordinates of B, C, and D.

Using the information provided, we know that B is 5 units away from A in the positive x-direction. Therefore, the x-coordinate of B is (-2) + 5 = 3 and the y-coordinate of B is the same as that of A, which is -5. So point B is (3,-5).

Next, we know that C is 10 units away from B in the positive y-direction. Therefore, the x-coordinate of C is the same as that of B, which is 3, and the y-coordinate of C is (-5) + 10 = 5. So point C is (3,5).

Finally, we know that D is 10 units away from C in the negative x-direction. Therefore, the x-coordinate of D is 3 - 10 = -7 and the y-coordinate of D is the same as that of C, which is 5. So point D is (-7,5).

The measure of x is 105° and the measure of y is 45°.

A square is a quadrilateral with four equal sides. There are many objects around us that are in the shape of a square. Each square shape is identified by its equal sides and its interior angles that are equal to 90°.

The given quadrilateral is square.

The diagonals of a square are angle bisectors. Therefore, the diagonals split the right angles of the square into two 45° angles.

Here, y°=45°

Here, a+60° =180°

a=120°

In quadrilateral y°+x°+a°+90°=360°

45°+x°+120°+90°=360°

The value of x from the given proportion is given as x = 10 after scalling both side of the equation.

A ratio is a divisional comparison of two quantities, and a proportion is the equality of two ratios. A ratio is often read as "x is to y" but may also be written as "x: y" or "x/y." The proportion equation, on the other hand, states that two ratios are equal.

The equality of two ratios is referred to as proportion. There is never a difference between two comparable ratios. The ratio sign (::) is used to express proportions, which aid in solving problems with ambiguous amounts. To put it another way, a percentage is an equation or a claim that shows the equality of two ratios or fractions. If a: b = c: d, then four non-zero values, a, b, c, are said to be in proportion. Let's now compare the two ratios, 3:5 and 15:25. In this case, 3:5 and 15:25 may both be written as 3:5 = 3/5 and 0.6, respectively. We may argue that these two ratios are proportionate because they are both equal.

There are two types of proportions :

The proportion is given by ,

x/12 = 15/18

⇒ multipling both side with 12 we get ,

x = (12*15)/18

The average number of gallons of fruit juice consumed per person in the country in 2006 is 3.56  gallons per person

The average value in a set of numbers is the middle value calculated by dividing the total of all the values by the number of values.

Given:

Total consumption of fruit = 1.78 billion gallons

= 1,780,000,000

Total population = 500 million

= 500,000,000

Average number of gallons of fruit juice consumed per person = 1,780,000,000 ÷ 500,000,000

= 3.56 gallons per person

About how many gallons would your class consume?

Assume, there are 7 students in your class

Average number of gallons of fruit juice consumed per person = 3.56 gallons / 7
