Which set of ordered pairs does not represent a function? Delta math

Answers

Answer 1

Answer:

The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates. The second example is not a function, because it contains the ordered pairs (1,2) and (1,5). These have the same first coordinate and different second coordinates

3. A second investment account starts with $2,000 and grows by $150 each year.
4. How does the growth of balances in the two account balances compare?

Answers

Answer:

The opening balance is the amount of funds in a company's account at the beginning of a new financial period. It is the first entry in the accounts, either when a company is first starting up its accounts or after a year-end.

The initial balance in the account was approximately $4215.

How to find the initial balance in the account?

The formula represents the relationship between the initial balance, the interest rate, the compounding period, and the time period.

To determine the initial balance in the account, we can use the formula for compound interest:

A = P(1 + r)ⁿ

where:

A = the ending balance

P = the initial balance

r = the annual interest rate as a decimal (5% = 0.05)

t = the number of years

Substituting the given values, we get:

[tex]5000 = P(1 + 0.05)^{(3.5)}[/tex]

[tex]5000 = P(1.05)^{(3.5)}[/tex]

Dividing both sides by [tex](1.05)^{(3.5)}[/tex], we get:

[tex]P = 5000/(1.05)^{(3.5)}[/tex]

Using a calculator, we get:

P ≈ $4215

Therefore, the initial balance in the account was approximately $4215.

An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 790 meters , and plane B was at an altitude of 1142 meters. Plane A losing altitude at 14 meters per second, and Plane B is losing altitude at 22 meters per second

Answers

Answer:

[tex]x=4.375[/tex]

Step-by-step explanation

From the question we are told

Plane A starts at altitude 790

Plane B starts at altitude 1142

Plane A losing altitude at 14 meters per second

Plane B is losing altitude at 22 meters per second

Generally the altitude of both plane is given by

Plane A= [tex]790-14x[/tex]

Plane B=[tex]1142-22x[/tex]

Therefore when they exist in the same altitude

[tex]790-14x[/tex] =[tex]1142-22x[/tex]

[tex]-350=-8x[/tex]

[tex]\frac{-350}{-8} =x[/tex]

Therefore

[tex]x=4.375[/tex]

is this mapping a function or not a function ¿ i’ll mark brainlist

Answers

Answer:

Not a function

Step-by-step explanation:

If it is a function, every input has only one output. Meaning if we graph it, it will pass the vertical line test.

If you want to think about it in x and y, all values of x can only correspond to one value of y.

In this case, we can see that the x-value 6 has 2 corresponding y-values (5 and 10), therefore, this mapping is not a function.

The length of a rectangle is 1 7/9 in and its width is 3/4 of its length. Find the area of this rectangle

Answers

Given:

Length of the rectangle = 1 7/9 = 17/9.Width = 3/4 × length = 3/4 × 17/9 = 17/12.

To find: The area of the rectangle.

Answer:

Formula to find the area of a rectangle = Length × Breadth.

Since we've calculated the length and breadth, let's substitute them directly.

17/9 × 17/12 = 289/108 = 2.67 [approx.]

Therefore, the area of the rectangle is 2.67 units.

The value of x is 5.8

Step-by-step explanation:

Here. we want to find the value of x

To do this, we need the appropriate trigonometric identity

As we can see 10 is the opposite as it faces the side given

x is the adjacent

The trigonometric identity relating opposite and adjacent is tan . Tan is the ratio of the opposite to the adjacent

Thus, mathematically;

Tan 60 = 10/x

x = 10/tan 60

x = 5.8

A rectangle has an area of 6x^(2) + 7x - 3 square units. Which of the following could represent the perimeter of the rectangle in terms of x?

A. 2x + 3
B. 5x - 2
C. 10x + 4
D. 20x + 8

Answers

Answer:

C

Step-by-step explanation:

Area is W×L. The area of the rectangle is 6x^(2) + 7x - 3.

So we write that as 6x^(2) + 7x - 3 = W×L

We can factor 6x^(2) + 7x - 3 to see the width and length.

Then, you get (2x + 3) (3x - 1) = W × L

Now you have to values for width and length

The formula for perimeter is 2W + 2L, you can choose which is width and which is length

Next, substitute the values in the formula: 2(2x + 3) + 2(3x - 1) and solve it. Done! :)
