there are four even integers in the top five rows of pascal's triangle. how many even integers are in the top 10 rows of the triangle?

Answers

Answer 1

There are 22 even numbers in the top 10 rows.

Pascal's triangle is the triangular array of numbers that begins with 1 on the top and with 1's running down the two sides of a triangle.

The tip of the triangle starts with 1 and the 1 starts continuing to both the ends of the triangle in each row and in between there is the sum.

For example:

                  1

                1   1

             1    2   1

         1   3    3     1

In the above manner, it continues.

now, for 10 rows the pascal triangle will be:

                       1

                     1   1

                  1    2   1

              1   3    3     1

          1   4    6      4      1

      1     5   10    10    5     1  

    1    6    15   20   15    6    1

  1    7    21    35   35  21    7    1

1   8     28   56   70   56   28   8  1

1   9   36    84   126  126   84  36 9  1

for five rows in the top, the even numbers are 2, 4, 6, 4 which are 4 in total.

for 10 rows in the top, the numbers are 2, 4, 6, 4, 10, 10, 6, 20, 6, 8, 28, 56, 70, 56, 28, 8, 36, 84, 126, 126, 84, 36

Hence there are 22 even numbers in the top 10 rows.

The domain of the function is -2 ≤ x < -5 and the range is -2 < y < 1

What is the domain of a function?

The domain of the function is the set of input values of the graph

What is the range of a function?

The range of a function is the set of output values of the graph.

How to determine the domain and the range?

The graph represents the given parameters

On the graph, we have the following endpoints

Closed circle at (-2, -1)

Open circle at (-5, -2)

Maximum = (0, 1)

The domain

The definition of the domain implies that the domain of a function is the set of x values of the graph.

Recall that

Closed circle at (-2, -1)

Open circle at (-5, -2)

Maximum = (0, 1)

Remove the maximum

Closed circle at (-2, -1)

Open circle at (-5, -2)

Remove the y coordinates

So, we have

Closed circle at (-2)

Open circle at (-5)

Combine the x values

-2 ≤ x < -5

The range

The definition of the range implies that the range of a function is the set of y values of the graph.

Recall that

Closed circle at (-2, -1)

Open circle at (-5, -2)

Maximum = (0, 1)

Remove the smaller larger y value of the endpoints)

Open circle at (-5, -2)

Maximum = (0, 1)

Remove the x coordinates

So, we have

Open circle at (-2)

Maximum = (1)

Combine the y values

-2 < y < 1

Hence, the domain of the function is -2 ≤ x < -5 and the range is -2 < y < 1

g= 4a+4/ 5ca solve for A

Answers

The solution of the equation given as g = 4a +4/5 for a is a = 1/20(5g - 4)

How to solve for in the equation?

The equation is given as

g = 4a +4/5

Multiply through the equation by 5

So, we have

5 * (g = 4a +4/5)

Evaluate the products

So, we have

5g = 20a + 4

Subtract 4 from both sides of the equation

So, we have

20a = 5g - 4

Divide through the equation by 20

So, we have

a = 1/20(5g - 4)

Hence, the solution of the equation given as g = 4a +4/5 for a is a = 1/20(5g - 4)

x = 22

180-51 = 129

y+16 = 129

-16       -16

y = 113

Answer:

x = 22

y = 113

Step-by-step explanation:

The angles marked as (2x+7) and (3x-15) are vertical angles, and therefore are equal to each other.

2x + 7 = 3x - 15 simplifying:

7 = x - 15

22 = x

Angles marked as (3x-15) and (y+16) form a linear pair and are therefore supplimetery. Now that we know the value of x, we can set up the following equation.

3(22) - 15 + y + 16 = 180 simplifying:

66 - 15 + y + 16 = 180

66 + y + 16 = 195

The function f(x)=x^2 times the graph of g(x) is f(x) translated to the left 6 units and down 5 units. What is the function rule for g(x)?

Answers

The function rule for g(x) is (x₊6)² ₋ 5. According to the given data we apply the translations onto the graph and from the graph we determine the function of g(x).

Given, the function of f(x)  = x²

The base graph is moved up or down in the y-axis direction when a graph is vertically translated. Each point on a graph is moved k units up the graph to translate it vertically. Shifting the f (x) k units vertically will allow you to sketch the equation g (x) = f (x) + k.

The graph of g(x) is f(x) translated to 6 units left and down 5 unit.

Draw the translations onto the graph. In the given graph provided, the yellow curve indicates the function g(x).

therefore g(x) = (x₊6)² ₋ 5 is the function from the graph.

b. x:y = (5k-3):2-k d. all are correct

Answers

All the given options are correct

How to determine which of the equation is true?

The variation expression is given as

(2x + 3y) ∝ (x + 5y)

Rewrite as an equation

So, we have

(2x + 3y) = k(x + 5y)

Remove the brackets

So, we have

2x + 3y = kx + 5ky

Collect the like terms

So, we have

kx - 2x = 3y - 5ky

This gives

x(k - 2) = y(3 - 5k)

Divide by both sides by y(k - 2)

x/y = (5k - 3)/(2 - k) --- option (a)

Multiply both sides by y

x = y(5k - 3)/(2 - k) --- option (b)

Express x/y = (5k - 3)/(2 - k) as ratio

x : y = (5k - 3) : (2 - k) --- option (c)

Hence, all the given options are correct

Answer:

Explicação passo-a-passo:

Podemos atribuir a incógnita x ao número de objetos que há na caixa. Assim, teremos as seguintes relações:

Metade dos objetos da caixa = 1/2x

Terça parte dos objetos da caixa = 1/3x

Portanto, o número de objetos que há na caixa será dado resolvendo a equação:

1/2x + 1/3x = 25

3/6x + 2/6x = 25

5/6x = 25

x = 25/(5/6)

x = 25 . (6/5)

The scale of the drawing by using proportion is 3 : 5.

According to the given question.

Melissa drew a scale drawing of a city.

The width of the park in the drawing is 36 inches.

And the actual width of the park is 60 yards.

As we know that, a proportion is a fraction of a total amount, and the measures are related using a rule of three.

Therefore, the scale of the drawing by using proportion

= 36iches/ 60 yards

= 3/5

= 3 : 5

the length of a new rectangular playing field is yards longer than the width. if the perimeter of the rectangular playing field is ​yards, what are its​ dimensions?

Answers

The width is 53 yards and the length is 108 yards.

What is the perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines a two-dimensional shape or length. The circumference of a circle or an ellipse is its perimeter. There are several practical applications for calculating the perimeter.

To find the dimensions:

First, we'll turn the information we have into an equation, where x is our unknown dimension.For this problem, it would be preferable if x equaled width.Let's write the equation down:X is the width, 2x + 2 is the length, and we multiply both by two because the field has two sides. Because the perimeter is 322, it will all add up to 322.2 × x + 2(2x +2) = 322

Now, solve as follows:

2 × x + 2(2x + 2) = 3222x + 4x + 4 = 3226x + 4 = 3226x = 318x = 318 ÷ 6x = 53

The width measures 53 yards.

To calculate the length, multiply 53 by two and add two.

53 × 2 + 2 = 106 + 2 = 108 yards

Therefore, the width is 53 yards and the length is 108 yards.

Answers

Answer is B. Infinitely many solutions

Step by step

Solve the equation

Change the first equation to y intercept form

y = -3x -6

Substitute it into the 2nd equation for y and solve

9x + 3(-3x-6) = -18

Distribution multiply

9x -9x -18 = -18

Add 18 to both sides to isolate x

9x -9x -18 + 18 = -18 + 18

Combine like terms

0 = 0

Since 0 = 0 for any value of x, the system of equations has infinite solutions.

Another way to write this rule is (x, y) = (x - 8, y + 4)

Which is another way to write this rule?

The translation rule is given as:

T–8, 4(x, y).

The above means that

x = x - 8

y = y + 4

Express as a transformation rule

So, we have

(x - 8, y + 4)

What is f(f(x))?

f(f(x)) is a composite function, hence:

For x = a, first we calculate the numeric value at x = a.Then we calculate the numeric value at x = f(a).

What is a limit?

A limit is the value that a function f(x) tends as x tends to a value. It there are no undetermined values, we can just verify the numeric value from the graph, but with undetermined values, there are multiple things to look at.

For this function, looking at the graph, we have that:

f(0) = 2, as when x = 0, f(x) = 2.Thus, lim x -> 0 f(f(x)) = lim x - > 2 f(x), because f(0) = 2.Both to the left of x = 2 and to the right of x = 3, from the graph, f(x) approaches 3, hence lim x - > 2 f(x) = 3.
