In this case we know that the parabola does not cross the x-axis, thus, the quadratic equation has no solutions.

For a quadratic function (also called a parabola)

y = a*x^2 + b*x + c

the solutions of the quadratic equation are the values of x such that:

a*x^2 + b*x + c = 0

Now, remember that the values with y = 0 are called the x-intercepts, then the solutions of the above equation are x-intercepts.

And here we know that the parabola does not cross the x-axis, thus, the quadratic equation has no solutions.

Answer:

I believe the answer is y=3,−3

Step-by-step explanation:

Answer: 74.539

Step-by-step explanation:

Answer:

-4×(2×1)=8x-2-4

solve in ( )

-4×3=8x-2-4

multiply -4 to 3

-12=8x-2-4

add 2 and 4 to both sides

-6=8x

divide -6 to 8 and you will get the answer

x=-0.75

Answer:

x = -0.25 (or) -1/4

Step-by-step explanation:

Let's solve the problem,

→ -4 × (2 × 1) = 8x - 2 - 4

→ -4 × 2 = 8x - 6

→ -8 = 8x - 6

→ 8x = -8 + 6

→ x = -2/8

→ [ x = -0.25 ]

Thus, solution is -0.25.

Step-by-step explanation:

[tex]f^{-1}(-33)=k \implies f(k)=-33 \\ \\ 9-6k=-33 \\ \\ -6k=-42 \\ \\ k=7[/tex]

Answer:

f^-1(33) = 7

Step-by-step explanation:

As the question is asking for the inverse function we do the following steps:

Change f(x) into y :

y = 9 -6x

Swap x and y :

x = 9-6y

Solve for y :

Subtract 9 from both sides :

x-9 = -6y

Divide both sides by -6 :

(x-9)÷ -6 = y

Change y back into f(x) :

f(x)  = (x-9)÷ -6

Now substitute -33 into x :

((-33)-9) ÷ - 6 =

-42 ÷ -6 =

The results for the connected graph H, obtained by using graph theory are;

First part;

There are 22 vertices in the spanning tree

Second part;

There are 22 vertices in H

Third part;

D. H has at least 21 edges

The given parameters are;

H = A connected graph

Number of edges in the spanning tree of H = 21

First part

Required:

The number of vertices in the spanning tree of H

Solution;

In graph theory, a spanning tree is one that contains all the vertices of the graph.

The number of edges in a tree that has n vertices is 'n - 1'

Therefore;

Number of edges = n - 1 = 21

n = 21 + 1 = 22

Second part;

From the definition of a spanning tree, the number of vertices in H is equal to the number of vertices in the spanning tree which is 22

Third part;

Let m represent the number of edges in H.

Therefore, the number of edges that should be deleted from H to get the spanning tree is 'm - (n - 1)', which gives;

The number of edges in the given spanning tree is n - 1 = 21

Which gives;

Therefore;

D. H has at least 21 edges

The number between 10 and 100 which has 5 base ten blocks and one of the digits is 4 will be 41.

Let the two digits be x and y

There are 5 base ten blocks therefore the sum of the numbers will be 5

One of the digit is 4

So, let the value of x = 4

Putting the value of x in eq-1

4 + y = 5

y = 5 - 4

y = 1

Since tens placed number block is a greater than the ones block,

y > x

Step-by-step explanation:

The roots of the quadratic equation 4x² - 2x - 20 = x² + 9x are x = 5 and

x = - 7/6 respectively.

We have the following equation -

4x² - 2x - 20 = x² + 9x

We have to find its roots.

A quadratic equation is an algebraic equation of the second degree in x. In the standard form it can be written as ax² + bx + c = 0. In this - a and b are the coefficients of 'x' and 'x²' respectively and c is a constant term.

According to the equation -

4x² - 2x - 20 = x² + 9x

4x² - x² - 2x - 9x - 20 = 0

3x² - 11x - 20 = 0

Using quadratic formula, the roots of the equation will be -

x = (- b ± [tex]\sqrt{b^{2} - 4ac}[/tex]) / 2a

x = (11 ± 19)/6

x = 30/6   and  x = -7/6

x = 5  and  -7/6

Hence, the roots of the quadratic equation are 5 and -7/6.

Answer: Average velocity = 11.1 m/s

Step-by-step explanation:

Given data,

A baseball is tossed up into the air at an initial velocity = 16 m/s​.

The height of the baseball at time t​ in seconds is given by,

                            h(t) =  16t - 4.9t²  ​​(in meters).

So,  

The average velocity is,            

To calculate the velocity travelled by the ball, differentiate the function.

                           dh/dt = 16 - 2(4.9t)

                           dh/dt = 16 - 9.8t               (eq-1)

Let us assume,    t = [1,1.5]​

Substitute t for 1 in the above Differential function

                            dh/dt = 16 - 9.8 (1)

But ,

                           dh/dt = velocity

So,                     dh/dt = V                        

                          V = 16 - 9.8

                          V =  6.2 m/s

Therefore,

               Average velocity = ( U + V ) / 2

               Average velocity = (16 + 6.2)/2

               Average velocity = 22.2/2

               Average velocity = 11.1 m/s

Hence, Average velocity = 11.1 m/s.

Answer:

0.250

Step-by-step explanation:

Given from the question, we know that the summation (adding all values together) of all P(x) values is equal to 1.

And, we do know that P(2) = P(4).

This means , we will subtract all the known P(x) values from 1 to get the value of P(2) + P(4).

P(2) + P(4) = 1 - 0.0425 - 0.3750 - 0.0625 - 0.0200 = 0.500

Since P(2) = P(4), we divide 0.500 by 2 to get the value of P(2) and P(4).

P(2) = P(4) = 0.500 ÷ 2 = 0.250

m<6 = 117° based on the same-side-interior angles theorem

m<7 = 63° based on the corresponding angles theorem

Angles 3 and 6 are same-side interior angles, therefore, based on the same-side-interior angles theorem, their sum equals 180 degrees because they are supplementary to each other.

Thus:

m<3 + m<6 = 180

Substitute

63 + m<6 = 180

m<6 = 180 - 63

m<6 = 117°

En este caso sabemos que le diámetro es de 30 cm, entonces el radio será de:

R = 30cm/2 = 15cm

Y la generatriz es de 17cm, entonces G = 17cm

The equation of the line in slope-intercept form is: y = -3/10x + 13/10.

Given the points, (1,1) and (11,−2). Follow the steps explained below.

Step 1: Find the slope of the line:

Slope (m) = change in y / change in x = (-2 - 1)/(11 - 1)

Slope (m) = -3/10

Step 2: Substitute m = -3/10 and (a, b) = (1, 1) into y = mx + b to find the value of b

1 = -3/10(1) + b

1 = -3/10 + b

1 + 3/10 = b

b = 13/10

Step 3: Substitute m = -3/10 and b = 13/10 into y = mx + b

y = -3/10x + 13/10

Thus, the equation of the line in slope-intercept form is: y = -3/10x + 13/10.
