What is the nature of the roots of the quadratic equation 2x² 5 √ 3x 6 0?

Answer:

Step-by-step explanation:

Area of rectangle = 5*4

=> 20

Area of hemisphere = [tex]\pi[/tex]r^2 / 2

=> 3.14 * 4 /2

=> 6.28

Total area => 26.28

Answer:

(s - 1)(s² + s + 1)

Step-by-step explanation:

s³ - 1 ← is a difference of cubes and factors in general as

a³ - b³ = (a - b)(a² + ab + b²) , then

s³ - 1

= s³ - 1³

= (s - 1)(s² + s + 1)

The required factorized form of the given expression is (s - 1)(s² + s + 1).

Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).

We have been given that the expression below as

s³ - 1

We have to determine the factor of the given expression

As per the question, we have

s³ - 1

This is a difference between cubes and factors in general as

a³ - b³ = (a - b)(a² + ab + b²) , then

⇒ s³ - 1 = s³ - 1³

⇒ (s - 1)(s² + s + 1)

Thus, the required factorized form is (s - 1)(s² + s + 1).

The value of x from the given figure is 40 degrees

Geometry is a way of relating lines and angles using theorems;

To get the value of x, we will use the expression based on the circle theorem:

80 = 1/2(200 - x)

Cross multiply

80 * 2  = (200 - x)

160 = 200 - x

x = 200 - 160

x = 40

Hence the value of x from the given figure is 40 degrees

Step-by-step explanation:

[tex]\boxed{area \: of \: rectangle = length \times breadth}[/tex]

Area of shaded region

= Area of larger rectangle -area of smaller rectangle

Area of larger rectangle

= (3x -4)(2x +2)

= 3x(2x) +3x(2) -4(2x) -4(2) (Expand)

= 6x² +6x -8x -8

= 6x² -2x -8

Area of smaller rectangle

= (x -6)(x -3)

= x² -3x -6x +18 (Expand)

= x² -9x +18

Area of shaded region

= 6x² -2x -8 -(x² -9x +18)

= 6x² -2x -8 -x² +9x -18

= 5x² +7x -26

Answer:

Decimal 3rd row: 0.75

Fraction 3rd row: 75%

Decimal last row: 0.15

Fraction last row: 15%

Answer:

75%, 0.75

Step-by-step explanation:

The answer is 75% because if you do the math it takes 6 15's to reach the requirement of the Fraction that is on the right. So that would make the decimal form be 0.75. If you find any fault in my answer let me know. Thanks. Have a good day!

Answer:

e=g(h-f) or e=gh - gf

Step-by-step explanation:

Answer:

e = hg - fg

Step-by-step explanation:

Given

[tex]\frac{e}{g}[/tex] + f = h ( multiply through by g to clear the fraction )

e + fg = hg ( subtract fg from both sides )

e = hg - fg

Answer:

1. -3/1

2.negative

3.$18

Step-by-step explanation:

since the graph is going down, it is negative, and look at the ending points on the x and y-axis. 18/6 is 3. so the slop is -3 :)

Answer:

1. -3

2. negative

3. $18

Step-by-step explanation:

1. slope is rise/run so...

-3/1=-3

2. because run was a change of 3 DOWN the y axis we and run is a change of 1 to the right on x axis we have a negative slope. -3

3. she borrowed $18. Vertical intercept means the point where our line crosses the vertical axis. (Vertical axis is Y axis.)
