Answer:

a = 10, b = 5, c = 14, d = 25

Step-by-step explanation:

Plug in -2 for x ....

y = 2(-2)^2 + -2 + 4

y = 2(4) + 2

y = 10

Plug in -1 for x ....

y = 2(-1)^2 + -1 + 4

y = 2(1) + 3

y = 5

Plug in 2 for x ....

y = 2(2)^2 + 2 + 4

y = 2(4) + 6

y = 8 + 6

y = 14

Plug in 3 for x ....

y = 2(3)^2 + 3 + 4

y = 2(9) + 7

y = 18 + 7

y = 25

Answer:

this question is a very simple. you should start with the biggest triangle then follow the steps to find each side of other triangles. THE ANSWER İS ROOT FORTY ONE

Step-by-step explanation:

these are all right-angled triangles. even the smallest one with the x side.

so, we need to apply Pythagoras to get the missing sides and finally x.

c² = a² + b²

c is the Hypotenuse, the baseline of the triangle opposite of the 90 degree angle. a and b are the legs of the triangle enclosing the 90 degree angle.

so,

52² = 48² + side1²

2704 = 2304 + side1²

400 = side1²

side1 = 20

20² = 12² + side2²

400 = 144 + side2²

256 = side2²

side2 = 16

13² = 5² + (larger part of side2)²

169 = 25 + (larger part of side2)²

144 = (larger part of side2)²

larger part of side2 = 12

that means the smaller part of side 2 = 16-12 = 4.

x² = 5² + 4² = 25 + 16 = 41

x = sqrt(41)

So, D is the right answer option.

point A will represent the input-output values of the function.

What is number line ?

Number line is virtual representation of numbers along with coordinates axis with number equally spaced with equal number of interval.

In the graph of y = f(x),

For every x-value (input value), value of the function is the y-value (output value).

For the input value x = 2,

Output value of the function will be,

y = f(2)

Therefore, point A will represent the input-output values of the function.

Slope = (y₂ - y₁)  ÷  (x₂ - x₁)

          =  (-85 - (-83)) ÷  (-11 - 75)

          =  -2 ÷ -86

          = ¹/₄₃

Checking my answer:

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line. If the line passes through both of the points then we calculated the slope correctly.

                               ⇒  y - (-83) =  ¹/₄₃ (x - 75)

                               ⇒     y + 83 =  ¹/₄₃ (x - 75)

Answer:

Step-by-step explanation:

The smallest angle in the quadrilateral with a ratio of 7:4:5:2 is 40 degrees.

To find the smallest angle in the quadrilateral, we need to determine the ratio of the angles and find the corresponding value for the smallest angle.

Given the ratio of the angles as 7:4:5:2, we can assume that the smallest angle corresponds to the ratio of 2.

To calculate the smallest angle, we can consider the sum of the ratio values as a whole, which is 7 + 4 + 5 + 2 = 18.

Now, we can find the value of the smallest angle:

Smallest angle = (2/18) * 360 degrees

             = (1/9) * 360 degrees

             = 40 degrees.

Therefore, the smallest angle in the quadrilateral is 40 degrees.

Answer:

5/2, 9/4 and 19/7.

Step-by-step explanation:

Rational numbers can be written as a/b where a and b are integers ( b not = 0).

Explanation:

The variable x increases by 1 each time we move down the rows. This increase is constant or the same jump each time.

However, the variable y increases by different amounts. From y = 2 to y = 6, we have +4. Then from y = 6 to y = 12 is +6. This mismatch of increases is sufficient to prove we don't have a linear function. The function is nonlinear.

Visually, we can plot all of the points on the same xy grid. Notice that a straight line does not go through all four points. Rather, a parabola does, and the equation of the parabola is y = x^2+x which is the same as y = x(x+1).

Answer:

[tex]10 + (n - 1) 8[/tex]

Step-by-step explanation:

All arithmetic sequence can be written as:

[tex]a_{n} = a_{1} + (n - 1)d[/tex]

Where [tex]a[/tex] is the [tex]n^{th}[/tex] term of the sequence, [tex]a_{1}[/tex] the first term of the sequence and [tex]d[/tex] the common difference between terms.  

So in our sequence we have [tex]a_{1} = 10[/tex] and for find the difference substract two sequence terms.

[tex]d = a_{n+1} - a_{n} = 18 - 10 = 8[/tex]

Now replace the knowns terms in the general form:

[tex]a_{n} = 10 + (n - 1)8[/tex]

The simplified formula for the given arithmetic sequence is:

a(n) = a + 8 (n - 1)

It is a sequence where the difference between each consecutive term is the same.

We have,

The common difference between any two consecutive terms in an arithmetic sequence is constant.

In this case, the common difference is 8, as each term is obtained by adding 8 to the previous term.

Let the first term of the sequence be 'a', then the second term is 'a + 8', the third term is 'a + 16', and so on.

Therefore, the nth term of the sequence can be expressed as:

a + (n-1)d

where d is a common difference, which is 8 in this case.

So, the simplified formula for the given arithmetic sequence is:

a(n) = a + 8 (n - 1)

where a is the first term of the sequence and n is the position of the term in the sequence.

Thus,

The simplified formula for the given arithmetic sequence is:

a(n) = a + 8 (n - 1)
