Step-by-step explanation:

Answer:(0.5,-3.5)

Step-by-step explanation:

(-2+3/2)/2, (-5-2)/2

0.5,-3.5

Solution :

Given a quadratic equation :

[tex]ax^2+bx+c = 0[/tex]

Step 1 : [tex]ax^2+bx+c = 0[/tex]

Step 2 : [tex]ax^2+bx=-c[/tex]

Step 3 :  [tex]$x^2+\frac{b}{a}x = -\frac{c}{a}$[/tex]

Step 4 : [tex]$x^2+\left(\frac{b}{2a}\right)^2=\left(\frac{b}{2a}\right)^2\left(\frac{-c}{a}\right)$[/tex]

Step 5 : [tex]$\left(x+\frac{b}{2a}\right)^2=\left(\frac{b}{2a}\right)^2\left(\frac{-c}{a}\right)$[/tex]

Step 6 : [tex]$\left(x+\frac{b}{2a}\right)=\sqrt{\left(\frac{b}{2a}\right)^2\left(\frac{-c}{a}\right)$[/tex]

Step 7 : [tex]$x=\sqrt{\left(\frac{b}{2a}\right)^2\left(\frac{-c}{a}\right)} - \frac{b}{2a}$[/tex]

Answer:

Rs. 300

Step-by-step explanation:

The bicycle marked price = Rs. 2000

The amount the customer bought the bike given that there was some discount allowed by the shopkeeper including VAT = Rs. 1921

The VAT applied = 13%

The amount given as the discount = Required

The VAT is applied to the selling price

Let d represent the discount amount, we have;

The selling price = 2000 - d

The amount paid as VAT = (2,000 - d) × 13% = (2,000 - d) × 0.13

The amount the customer bought it including VAT = The selling price + The amount paid as VAT

The amount the customer bought it including VAT = Rs. 1921

∴ 1921 = 2000 - d + (2,000 - d) × 0.13 = 2,260 - 1.13·d

1.13·d = 2,260 - 1,921 = 339

d = 339/1.13 = 300

The amount given as discount, d = Rs. 300

Answer:

21

Step-by-step explanation:

If lines m and n are equal, line t intersects both of them at the exact same angle. This means that 6x+3=7x-19. Start moving the variables to one side. 3=x-19. Then move the numbers to the other side of the equation. x=21.

Answer:

Decreased

Strong negative

Step-by-step explanation:

The correlation Coefficient is used to show the strength and type of relationship which exists between the dependent and independent variable. The correlation Coefficient value ranges from - 1, to 1. With values closer to either - 1 or 1 depicting a strong relationship while those closer to 0 represents weak relationship. And correlation Coefficient of 0 indicates that no relationship exiata at all. Depending in the sign, that is positive or negative, positive sign means positive relationship while a negative sign represents a negative association. Positive association is interpreted as, for every increase in A, Variable B also increase and vice versa. For negative association, When A increases, B decreases and vice versa

Answer:

Step-by-step explanation:

Since all 3 of these angle come off a straight line, they all add up to equal 180. Thus,

2j + 32 + 6j - 2 + 30 = 180 and

8j + 60 = 180 and

8j = 120 so

j = 15

Answer:

The solution of the equation is:

Step-by-step explanation:

To solve the equation:

First, you must add the terms 3x/5 and 5:

Now, you pass the number that is dividing (5), to multiply to the other side of the equality and operate:

Next, you pass the number that is adding (25), to subtract to the other side of the equality and operate:

At last, you pass the number that is multiplying the unknown variable, to divide to the other side of the equality and operate:

If we use this value in the original equation, we can prove if it's the correct:

As you can see, the result x = 25 is the correct.

Answer:

The formula  is [tex]R =\frac {V}{I}[/tex]

Step-by-step explanation:

The formula V = I R shows the relationship between voltage, current, and resistance.

It is given by the Ohm's law.

According to this law, at constant temperature, the current flows in any conductor is directly proportional to the potential difference applied.

V = I R

where, V is the potential difference, I is the current and R is the resistance.

The resistance is given by

[tex]R = \frac{V}{I}[/tex]

Answer:

R = V over I

Step-by-step explanation:

You can substract 10 from 100 ten times :)

Answer:

10

Step-by-step explanation:

100 - 10 = 90 ( 1 )

90 - 10 = 80 ( 2 )

80 - 10 = 70 ( 3 )

70 - 10 = 60 ( 4 )

60 - 10 = 50 ( 5 )

50 - 10 = 40 ( 6 )

40 - 10 = 30 ( 7 )

30 - 10 = 20 ( 8 )

20 - 10 = 10 ( 9 )

10 - 10 = 0 ( 10 )

we subtract 10 from 100 10 times

Answer:

14.3%

Step-by-step explanation:

subtract 320 with 280 which is 40. divide 40 with 280 and multiply that will 100. You get 14.3%

Answer:

14.28 %

Step-by-step explanation:

cost price of an umbrella = 280

selling price of an umbrella = 320

profit% = SP - CP / CP *100%

=320 - 280/280 * 100

=40/280 * 100

=4000/280

=14.28

The image to the question is attached below.

Answer: The value of EN is 11.2 cm

Step-by-step explanation:

We are given:

The parallelograms ABCD and EFGH are congruent, which simply means

AB = EF

BC = FG

CD = GH   and

AD = EH

Area of ABCD = area of EFGH

Also, opposite sides of a parallelogram are equal. Thus,

AB = EF = CD = GH

BC = FG = AD = EH

It is given:

[tex]AD=10cm=FG\\\\\text{Area of ABCD}=112cm^2=\text{Area of EFGH}[/tex]

To calculate the area of a parallelogram, we use the equation:

[tex]Area=b\times h[/tex]

where, for parallelogram EFGH

b = base = FG = 10 cm

h = height = EN = ?

Area = [tex]112cm^2[/tex]

Plugging values in above equation, we get:

[tex]112cm^2=10cm\times EN\\\\EN=\frac{112cm^2}{10cm}=11.2cm[/tex]

Hence, the value of EN is 11.2 cm

Answer:9z

Step-by-step explanation:10z-1z=9z

Answer:

the answer would be 3

Step-by-step explanation:

9z = 3

Answer:

Options A

Step-by-step explanation:

Properties of the graph given for the function 'g',

y-intercept of the function 'g' → y = -4

Minimum value of g(x) → y = -4 (Value of the function at the lowest point)

Roots of g(x) → x = -2, 2

At x = 4,

g(4) = 11

Another function is,

f(x) = -x² - 4x - 4

     = -(x² + 4x + 4)

     = -(x + 2)²

Properties of the function f(x) = -(x + 2)²,

y-intercept (at x = 0) of the function 'f',

y = -(x + 2)²

y = -4

Since, leading coefficient of the function is (-1) therefore, graph will open downwards and the maximum point will be its vertex.

Maximum value of the function 'f' = Value of the function at the vertex

Coordinates of vertex → (-2, 0)

Therefore, maximum value of 'f' = 0

Roots (at y = 0) of the function 'f' → x = -2

At x = 4,

f(4) = -(4 + 2)²

     = -36

Therefore, Options A will be the correct option.

Answer:

Volume of the solid is 377 cm³.

Step-by-step explanation:

Volume of the cylinder = [tex]\pi r^{2}h[/tex]

Here, r = radius of the cylinder

h = Height of the cylinder

By substituting the values in the formula, (r = 4 cm and h = 10 cm)

Volume of the cylinder = [tex]\pi (4)^2(10)[/tex]

                                      = 160π

Since one fourth of the cylinder is removed,

Volume of the remaining cylinder = 160π - [tex]\frac{160\pi }{4}[/tex]

                                                        = 160π - 40π

                                                        = 120π

                                                        = 120(3.14)

                                                        = 376.8 cm³

                                                        ≈ 377 cm³

Volume of the solid is 377 cm³.
