Answer: Option b

[tex]f (1) = 0[/tex]

Step-by-step explanation:

For a function of the form

[tex]f (x) = ax ^ n + bx ^ {n-1} + ... + c[/tex]

Where n is the main exponent of the polynomial and a, b c are the coefficients of the variables then this polynomial can be written based on its factors as

[tex]f (x) = a (x-h) (x-k) (x-s)...[/tex]

Where [tex]x = h[/tex], [tex]x = k[/tex], [tex]x = s[/tex], ... are the points where [tex]f(x) = 0[/tex]

Therefore if for this case we know that

[tex](x-1)[/tex] is a factor of a polynomial function [tex]f (x)[/tex] then it is fulfilled that

[tex]f (1) = 0[/tex]

units like radius, height, width, length or segments are single units, like meter or feet.

areas are double units, so they'd be in say meter² or feet².

volumes are triple units, namely like meter³ or feet³.

Answer:

16%

Step-by-step explanation:

100% - 68% = 32%

32%/2 = 16%

Let n be a number

2n - 3 = 55

Add 3 to both sides

2n + (-3 + 3) = 55 + 3

2n = 58

Divide 2 to both sides

2n/2 = 58/2

n = 29

The probability that two 1-6 number cubes both land on an even number is calculated by multiplying the individual probabilities for each cube (1/2 x 1/2), resulting in a final probability of 0.25, or answer 'C. 0.25.'

To determine the probability that two 1-6 number cubes land on an even number, we first recognize that there are three even numbers on each cube (2, 4, and 6), and thus three favorable outcomes out of six possible outcomes for each individual number cube roll. To calculate the probability of two independent events both occurring (in this case, both number cubes landing on an even number), we multiply the probabilities of each event.

The probability for one cube is 3/6, or 1/2. Therefore, for two cubes, the probability is (1/2) x (1/2) = 1/4. Expressed as a decimal, 1/4 is equivalent to 0.25.

The correct answer to the question is 'C. 0.25.'

Have a great day!!

First, distribute the negative to the second set of parentheses:

(9x2+10x+4)+(-9x2-5x+1)

Now, add like term:

9x2-9x2=0

10x-5x=5x

4+1=5

Recombine each sum for the final answer:

5x+5

Hope this helps!!

The difference is 5x + 5

First, remove the parentheses by distributing the negative sign:

9x² + 10x + 4 - 9x² - 5x + 1

Combine like terms:

10x + 4 - 5x + 1 = 10x - 5x + 4 + 1 = 5x + 5

Therefore, the difference is 5x + 5

Answer:  5

Step-by-step explanation:

f(5) = 2 means that when x = 5, y = 2 --> (5, 2)

f⁻¹(2) is the inverse (when the x and y are swapped) --> when x = 2, y = 5

Answer:

c.1/3

Step-by-step explanation:

To check, multiply 1/3 each time to each number. Note that the first number is 27:

27 x 1/3 = 27/3 = 9

9 x 1/3 = 9/3 = 3

3 x 1/3 = 3/3 = 1

1 x 1/3 = 1/3

etc.

This means that the common ratio decreases by the common multiple of 1/3.

Answer:

Step-by-step explanation:

By observation, you can see that the irregular polygon can be split into 4 triangles (see attached image). We know that the sum of the internal angles of 1 triangle is always 180 degrees. Hence the sum of all the internal angles of the polygon is,

180 degrees x 4 triangles = 720 degrees.

Therefore Angle B,  

= sum of internal angles - sum of all other known angles

= 720 - (133 +102+117+90+170)

= 108 degrees.

The measure of angle B is 108 degrees.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

We can divide the given polygon in split into 4 triangles.

Using, angle sum property,

The sum of the internal angles of triangle is always 180 degrees.

Hence the sum of all the internal angles of the polygon is,

=180 x 4 triangles

= 720 degrees.

Now, angle B

= 720 - (133 +102+117+90+170)

=720 -612

= 108 degrees.

Hence, angle B is 108 degrees.

Step-by-step explanation:

Answer:

The correct answer is: 21x + 14 = 98; x = 4.

Step-by-step explanation:

She needs to type the notes she recorded in her 98-page workbook. If whe types x hours at a rate of 21 pages per hour, and 14 pages are already done. Then the equation is:

21x + 14 = 98;

Now, the number of hours she will take to complete the task can be found by solving for 'x':

21x = 98 - 14

21x = 84

x = 4.

Therefore, the correct option is: 21x + 14 = 98; x = 4.

Answer:

21x + 14 = 98; x = 4

Step-by-step explanation:

Camille has already typed notes from the first 14 pages of her workbook, and she types for x hours at a rate of 21 pages per hour. An expression for the one side of the equation needs to represent the total number of pages she has typed in terms of x. The number of pages Camille has typed after x hours is represented by the expression 21x + 14.

The workbook has a total of 98 pages. Thus, the other side of the equation which represents the number of pages Camille has typed after x hours is 98.

Hence, the equation that represents the number of pages she has typed after x hours is 21x + 14 = 98.

Solve the equation to determine how many hours it will take Camille to complete the task.

So, x = 4. Therefore, it takes Camille 4 hours to complete the task.

Comparing 6/5 and 4/5:

6/5 > 4/5

therefore

6/5 > 4/5

Answer:

15/17

Step-by-step explanation:

sin A = side opposite A/ hypotenuse

         = a/ c

         =15/17

We use the definition of sine, which leads to sin A = a/c = 15/17, giving sin A = 0.8824.

To find sin A, we can use the definition of sine in a right-angled triangle, which is the ratio of the length of the opposite side to the length of the hypotenuse.

In this case, sin A = opposite/hypotenuse = a/c = 15/17. Therefore, sin A = 0.8824, rounded to four decimal places.

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 5, 2) and (x₂, y₂ ) = (- 9, 9)

d = [tex]\sqrt{(-9+5)^2+(9-2)^2}[/tex]

  = [tex]\sqrt{(-4)^2+7^2}[/tex]

  = [tex]\sqrt{16+49}[/tex] = [tex]\sqrt{65}[/tex] ≈ 8 ( nearest unit )

Answer:  The required distance between my house and the subway stop is 8 units.

Step-by-step explanation:  Given that a grid shows the positions of a subway stop and my house. The subway stop is located at (-5,2) and my house is located at (-9,9).

We are to find the distance, to the nearest unit, between my house and the subway stop.

We will be using the following formula :

Distance formula :  The distance between the points (a, b) and (c, d) is given by

[tex]D=\sqrt{(c-a)^2+(d-b)^2}.[/tex]

Therefore, the distance between the points (-5, 2) and (-9, 9) is given by

[tex]D\\\\=\sqrt{(-9-(-5))^2+(9-2)^2}\\\\=\sqrt{(-9+5)^2+7^2}\\\\=\sqrt{4^2+49}\\\\=\sqrt{16+49}\\\\=\sqrt{65}\\\\=8.06.[/tex]

Rounding to the nearest units, we get

D = 8 units.

Thus, the required distance between my house and the subway stop is 8 units.

first off let's recall that a square has all equal sides, so its area is just one side squared, namely A = s², or A = (s)(s).

we know the area is 16j² + 24j + 9, that simply means that two twin factors are in it, and it also means that the area polynomial is a perfect square trinomial.

Answer:

512.4 miles

Step-by-step explanation:

The distance from city to beach town = 500 miles

Distance from airport to hotel = 20 kilometers

In order to find the total distance we have to convert the kilometers in miles to bring both quantities in same unit

So,

1 kilometer = 0.62 miles

20 kilometers = 20*0.62 =12.4 miles

As both the quantities are in same unit,

The total distance = Distance from city to beach town + distance from airport to hotel

= 500 + 12.4

= 512.4 miles

Hence, total distance covered by them is 512.4 miles ..
