Answer:

A line is an infinite two dimensional figure

Answer:

( x-6)^2 -17

Step-by-step explanation:

X^2 - 12x + 19

we need it in given below form

(x + a)^2 + b

we know that

[tex](x + a)^2 = x^2 + 2ax + a^2\\[/tex]

lets convert that in same form

X^2 - 12x + 19 = x^2 + 2(-6)x + 19

comparing x^2 + 2(-6)x to x^2 + 2ax

we have a -6

now

(x-6)^2 = x^2 + 2(-6)x + 36

36 is missing in the x^2 + 2(-6)x + 19 hence to get that

we add and subtract 36 in the above equation

so we have

x^2 + 2(-6)x + 19 + 36 -36

rearranging  it \

(x^2 + 2(-6)x  + 36) -36 + 19    (x^2 + 2(-6)x  + 36 =( x-6)^2)

=>( x-6)^2 -17

comparing the above equation to

(x + a)^2 + b

we have a = -6

b = -17

( x-6)^2 -17

Answer:

m(∠OAC) = 52°

Step-by-step explanation:

A, B and C are the pints on a circle with center O.

m(∠ABC) = 38°

By the central angle theorem,

"Central angle subtended by two points on a circle measure the twice of the inscribed angle subtended by these points."

m(∠AOC) = 2m(∠ABC)

m(∠AOC) = 2 × 38° = 76°

Now in ΔAOC,

AO and OC are the radii, so the angles opposite to radii will measure the same.

∠OAC ≅ ∠OCA

Since, sum of all the interior angles of a triangle is 180°.

m(∠OAC) + m(∠OCA) + m(∠AOC) = 180°

m(∠OAC) + m(∠OAC) + 76° = 180°

2m(∠OAC) = 180° - 76°

2m(∠OAC) = 104°

m(∠OAC) = 52°

Answer:

Step-by-step explanation:

Linear function is represented by the data given on the table.

" Linear equation is an algebraic expression in which highest exponent of the given variables is one. It represent a straight line."

General form of linear equation

y = ax + b

According to the data given in the table,

When x = 0 , y = -3 ,

Substitute the given values of x and y in general form of linear equation

- 3 = a × 0 + b                          

⇒ - 3 = b                                 ____(1)

When x = 1 , y = 5

  5 = a × 1 + b                        

  5 = a + b                                         ____(2)

Substitute the value of b in (2) we get,

 5 = a + ( -3)

⇒ a = 8

Substitute the value of 'a' and 'b' in general form of linear equation and check whether it is true for other values of x and y.

y = 8x  - 3

check for the x = 2

   y = 8(2) -3

⇒ y = 13

Yes , it is correct.

When x =3

   y = 8 (3) - 3

⇒ y = 21

It is correct.

Hence, we conclude that Linear function is represented by the data given on the table.

Answer:

$54 for 4 months   $89 in total

Step-by-step explanation:

Lisa paid $35 at first

then she paid 0.75  per song which is 0.75 *18 = $13.5

Then just multiply 13.5 by 4 b/c of 4 months

The total amount Liza has spent after 4 months is $89.

Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”. For example, 2x – 5 = 13.

Given that, Lisa paid $35.00 to join an online music service, she purchases 18 songs each month at a cost of $0.75 per song,

we need to find the total amount she paid after 4 months,

So, the cost of 18 songs = 0.75 x 18 = $13.5

The cost of 18 songs in 4 months = $54

Now, the total amount she paid = $54 + $35 = $89

Hence, the total amount Liza has spent after 4 months is $89.

Answer:

There are 243 ways but the balls in the boxes.

Step-by-step explanation:

There are 109375 ways to put 5 balls in 2 boxes when the balls and boxes are distinguishable by using counting principles and combinatorics

To solve this problem,  use the concept of the multiplication principle, also known as the multiplication rule of counting.

Here's a step-by-step explanation:

Determine the number of choices for each ball: Since the balls are distinguishable, we have 5 choices for the first ball, 5 choices for the second ball, and so on, until we have 5 choices for the fifth ball. This can be represented as:

[tex]5 \times 5 \times 5 \times 5 \times 5.[/tex]

Determine the number of choices for each box: Since the boxes are distinguishable, each ball can be placed in either box 1 or box 2. Thus, there are 2 choices for each ball. This can be represented as:

[tex]2 \times 2 \times 2 \times 2 \times 2.[/tex]

To find the total number of ways, we multiply the number of choices for each ball with the number of choices for each box:

Total number of ways [tex]= (5 \times 5 \times5 \times5 \times5) \times(2 \times2 \times2 \times2 \times2)[/tex]

On multiply gives:

=  3125\times 32 = 109,375.

Therefore, there are 109375 ways to put 5 balls in 2 boxes when the balls and boxes are distinguishable.

Answer:

x = 25

Step-by-step explanation:

Since it is an equilateral triangle it means that all the sides are 50. Each side is equal so, if you divide 150 by 3 you get 50. (and since perimeter is the adding of each side)

Now you want to try to figure out what the altitude is of the triangle so you divide it in half. Making the bottom side length now 25 because half of 50 is 25. You now have to use Pythagoreans theorem to figure out the altitude:

c^2 - a^2 = b^2

50^2 - 25^2 = b^2

2500 - 625 = b^2

1875 = b^2

√1875 = b

43.30127019

now you put that into the expression: x√3:

x√3 = 43.30127019

x = (43.30127019) ÷ (√3)

x = 25

Answer: 121871

Step-by-step explanation:

Current population = 98000

Rate of increase = 3.7% / year

Total time = 2020 - 2014 = 6 years

Population in 2020 = 98000 * (1+ (3.7/100))^6

= 98000 * (1.037)^6  =  98000 * 1.243576 = 121870.505

The domain of the line segment will be [-5, 1) and the range of the line segment will be [-4, 7).

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

A line segment in mathematics has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a path that joins two places.

The domain means all the possible values of x and the range means all the possible values of y.

From the graph, the domain of the line segment will be [-5, 1) and the range of the line segment will be [-4, 7).
