Step-by-step explanation:

The solution to the quadratic equation is x = -6 ± 2√7

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

x² + 12x + 25 = 17

Subtracting 17 on both sides , we get

x² + 12x + 8 = 0

And , roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

On simplifying , we get

x = ( -12/2 ) ± √ ( 12 )² - 4 ( 1 ) ( 8 ) / 2

x = -6 ± √ ( 144 - 32 ) / 2

x = -6 ± √112/2

And , the value of x = -6 ± 2√28/2

x = -6 ± 2√7

Hence , the solutions are x = -6 + 2√7 and -6 - 2√7

Answer:

B. 203.403

Step-by-step explanation:

2 times 100 = 200

3 times 1 = 3

4 times 1/10 = 0.4

3 times 1/1000 = 0.003

200 + 3 = 203

203 + 0.4 = 203.4

203.4 + 0.003 = 203.403

Answer/Step-by-step explanation:

The interest rate is 15% for every 3 years. To find the interest rate subtract the money from the total. Then, divide the total from the difference. Now subtract the quotient from 100 and multiply it by 100 to fin the percentage.

3000 - 450 = 2550

2550 ÷ 3000 = 0.85

100 - 0.85 = 0.15

0.15 x 100 = 15%

Step-by-step explanation:

Let assume peter be

And, then mary is 2p ÷ 3

So

The equation would be  

2p ÷ 3  - 2 = 1 ÷ 2 (p + 5)

4p - 12 = 3p + 15

p = 27

So Peter age be 27

And, the mary age is

= 2 (27) ÷ 3

= 18

Hence, the Peter age be 27

Answer:

y=1/2x+5

Step-by-step explanation:

Plug it into the formula for a point and a slope.

(y-(y(subscript 1)))=(m)(x-(x(subscript 1)))

Y-8=1/2(x-6)

Then multiply the 1/2 to the x and -6. After you do that, move everything so that it has y by itself on the left. Your ending should be y=1/2x+5.

Answer:

90

Step-by-step explanation: by taking 10% off of 900, you get 810; meaning 90 was subtracted

The number of units the 10% sales decline represents is 90

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"

Given here projected sales = 900 but the actual sales is 10% less than this amount , thus  actual sales = 900 - 10% of 900

                                             = 900 -( 10/100 )×900

                                             = 900 - 90

                                             = 810  

 Hence,  the number of units the 10% sales decline represents is     900-810 =90

Answer:

x= -7 and y=37

Step-by-step explanation:

substitute y=-26-9x in -2x-y=12

-2x-(-26-9x)=12

-2x+26+9x=12

-2x+9x=12-26

7x= -14

x= -14/2

x= -7

substitute x=-7 in y=26-9x

y= -26-9x

y= -26-9(-7)

y= -26+63

y=37

x= -7 and y=37

The volume of the cylinder is 2411.5 cm³ in the given figure. which is the correct answer would be an option (A).

The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder.

V = πr²h

where 'r' is the radius of the base (circle) of the cylinder

'h' is the height of the cylinder

As per the given figure,

The radius of a cylinder is 16 cm and the height of the cylinder is 3 cm.

The volume of a cylinder = πr²h

The volume of a cylinder = π(16)² × 3

The volume of a cylinder = 3.14(256) × 3

The volume of a cylinder = 2411.5 cm³

Thus, the volume of the cylinder is 2411.5 cm³ in the given figure.
