In quadratic polynomial if leading Coefficient is - V then its graph is opened​

Answer»

Recall that a quadratic function has the form

f

(

x

)

=

a

x

2

+

b

x

+

c

.

where  

a

,  

b

, and  

c

are constants, and  

a

0

.

The graph of a quadratic function is a U-shaped curve called a parabola.  This shape is shown below.

A parabola has a maximum or a minimum, called the vertex, an axis of symmetry through the middle of the parabola, a y-intercept where it crosses the y-axis, and can have as many as two x-intercepts where it crosses the x-axis.

Parabola : The graph of a quadratic function is a parabola.

In graphs of quadratic functions, the sign on the coefficient  

a

affects WHETHER the graph opens up or down. If  

a

<

0

, the graph makes a frown (opens down) and if  

a

>

0

then the graph makes a smile (opens up). This is shown below.

Direction of Parabolas: The sign on the coefficient  

a

determines the direction of the parabola.

Features of Parabolas

Parabolas have several recognizable features that characterize their shape and placement on the Cartesian plane.

Vertex

One important FEATURE of the parabola is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph.

Axis of Symmetry

Parabolas also have an axis of symmetry, which is parallel to the y-axis. The axis of symmetry is a vertical line drawn through the vertex.

y

-intercept

The y-intercept is the point at which the parabola crosses the y-axis. There cannot be more than one such point, for the graph of a quadratic function. If there were, the curve would not be a function, as there would be two  

y

values for one  

x

value, at zero.

x

-intercepts

The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts REPRESENT the zeros, or roots, of the quadratic function, the values of  

x

at which  

y

=

0

. There may be zero, one, or two  

x

-intercepts. The number of  

x

-intercepts varies depending UPON the location of the graph (see the DIAGRAM below).

If 2 ^ (2x - 1) = 32 , Value of x is: (a) 1 (b) 2 (c) 3 (d) 4​

Answer»

Answer:

(c)  x = 3

Step-by-step explanation:

2^(2X-1) = 32

We know that 32 = 2^5

2^(2x-1) = 2^5

2x - 1 = 5

2x = 6

x = 3

Hence, the value of x is 3, Option (c)

Cramer 's ruel 6x-4y=12 4x+2y = 8write coorect answer for brainlist ​

Answer»

Answer:

x = 0 , y = -3      

Step-by-step explanation:

6x-4y=12 4x+2y = - 8

6x-4y  = 4x+2y

Coeffcient Matrix

Determinant , D = 6/4 , -4/2 = 6 *  2  +( - 4) * 8 = 12 - 24 = -12

X-Matrix  

= 12/8 , -4/2= 12 * 2 - (-4) * -8 = 24 - 24 = 0

Y-Matrix

= 6/4 , 12/2 = 6 * 2 -  12 * 4 =  12 -  48 = -36

3) Now,

   By  Cramer's Rule,

  x= 0/12 = 0  

  y = -36/12 = -3  

x = 0 , y = -3

x=\frac{-5+-\sqrt 65}{4}

Step-by-step explanation:

2x²+5x-5​

Here, a= 2, b=5, c=(-5)

x=\frac{-b+-\sqrt b^{2} - 4ac}{2a}

x=\frac{-5+-\sqrt 5^{2} - 4(2)(-5)}{2(2)}

x=\frac{-5+-\sqrt 25 +40}{4}

The distance light travels in one year is approximately 5,870,000,000,000 miles. The distance light travels in 100 years is:??.or koi mujhe points de do ~♥~​

Answer»

Step-by-step explanation:

The distance of light travel in ONE year= 587×10

The distance of light travel in one year= 587×10 10

The distance of light travel in one year= 587×10 10 .

The distance of light travel in one year= 587×10 10 .So, the distance travelled by light in 100 YEARS =587×10

The distance of light travel in one year= 587×10 10 .So, the distance travelled by light in 100 years =587×10 10

The distance of light travel in one year= 587×10 10 .So, the distance travelled by light in 100 years =587×10 10 ×100=587×10

The distance of light travel in one year= 587×10 10 .So, the distance travelled by light in 100 years =587×10 10 ×100=587×10 12

The distance of light travel in one year= 587×10 10 .So, the distance travelled by light in 100 years =587×10 10 ×100=587×10 12 .

An AP consists of 50terms of an AP are 4 and-8 respectively, which term of this AP is zero? step by step explanation​

Answer»

According to the question:

n = 50

a3 = 12

a + 2 * d = 12 -(1)

a50 = 106

a + 49 * d = 106 -(2)

After solving (1) and (2) you will get

47 * d = 106 – 12

d = 94/47 = 2

and a = 12 -4 = 8

So, a29 = a + 28 * d

a29 = 8 + 28 * 2

a29 = 64

So the 29th TERM of the GIVEN A.P. will be 64.

The diagonal of a rectangular field is 16 metres more than the shorter side. If the longer side is 14 metres more than the shorter side, then find the lengths of the sides of the field

Answer»

Step-by-step explanation:

Given:

The diagonal of a rectangular field is 16m more than the shorter SIDE.

LONGER side is 14m more than the shorter side.

To find :

Lengths of the SIDES of the field.

Solution :

Let the length of the shorter side be x m.

Length of longer side = x + 14 m.

Length of diagonal = x + 16 m.

Using Pythagoras theorem :

  • x² + (x + 14)² = (x + 16)²
  • x² + 196 + x² + 28x = 256 + x² + 32
  • x² - 4x - 60 = 0
  • x² + 6x - 10x - 60 = 0
  • x(x + 6) - 10(x + 6) = 0
  • (x - 10) (x + 6) = 0
  • x = -6, 10 [x ≠ -'ve]
  • x = 10

Lengths of the sides of the field :

  • x = 10 m
  • x + 14 = 24 m

∴ The length of the sides is 10 m and 24 m.

Verification :

  • x² + (x + 14)² = (x + 16)²

⇒ (10)² + (24)² = (10 + 16)²

⇒ 100 + 576 = 26²

676 = 676

∴ L.H.S = R.H.S

Let the shopkeeper buy x number of books.

According to the given condition cost of x books = Rs. 80

Therefore cost of each book = \large \frac{80}{x}

Again when he had brought 4 more books

Then total books in this case =x+4

So cost of each book in this case =

\large \frac{80}{x + 4}

According to Question,

\large \frac{80}{x}  -  \frac{80}{x + 4}  = 1 \\  \\ \large \frac{80(x + 4) - 80x}{x(x + 4)}  = 1\\  \\ \large  {x}^{2}  - 20x - 16x - 320 = 0 \\  \\ \large (x - 16)(x + 20) = 0\\  \\ \large x = 16 \:  \: or \:  \: x = -  20

{Since no. of books cannot be negative, we ignore -20}

HENCE the shopkeeper brought 16 books

9150.
