-23

Step-by-step explanation:

x2−x+6=0

Step 1: Find discriminant with a=1, b=-1, c=6.

b2−4ac

=(−1)2−4(1)(6)

=−23

Answer:

−23

Answer:

no solution

Step-by-step explanation

[tex]x^{2}-x+6=(x^{2}-2.\frac{1}{2}x+\frac{1}{4})+6-\frac{1}{4}=(x-\frac{1}{2})^{2}+\frac{23}{4}[/tex]

see : [tex](x-\frac{1}{2})^{2}\geq 0 => (x-\frac{1}{2})^{2}+\frac{23}{4}\geq 0+\frac{23}{4}>0[/tex]

but x² - x + 6 =0

=> it is unreasonable

Answer:

x = 10

y = 10

Step-by-step explanation:

60x + 40y = 1000

x + y = 20

a. If x is number of kilos of mango and number of kilos of apple, then the equation is: x + y = 20

b. Equation for the cost of fruits

60x + 40y = 1000

c. The system equations are x + y = 20 and 60x + 40y = 1000

d. Solve by any method.

60x + 40y = 1000 (2)

x + y = 20 (1)

x = 20 - y

Substitute into (2)

60x + 40y = 1000 (2)

60(20 - y) + 40y = 1000

1200 - 60y + 40y = 1000

- 20y = 1000 - 1200

-20y = - 200

y = -200/-20

= 10

y = 10

Substitute y = 10 into (1)

x + y = 20

x + 10 = 20

x = 20 - 10

x = 10

(e) Check if your result will satisfy the problem.​​

60x + 40y = 1000

60(10) + 40(10) = 1000

600 + 400 = 1000

1000 = 1000

Creating a system of linear equations and solving using elimination method, the number of mangoes and apples purchased is 10.

Let :

The system of equations which could be formed :

From (1)

Substitute a = 20 - b into (2)

40(20 - b) + 60b = 1000

800 - 40b + 60b = 1000

Collect like terms

-40b + 60b = 1000 - 800

-20b = - 200

b = 200/20

b = 10

Substitute b = 10 in (3) :

a = 20 - b

a = 20 - 10

a = 10

Therefore, the Number of apples and mangoes purchased is 10

Answer:

1284 gallons

Step-by-step explanation:

The swimming pool already contained 486 gallons.

Then, Jaxson filled the pool for 95 minutes, so, the total amount of water in the pool at the end of 95 minutes = 486 + filled amount in 95 minutes.

The rate of filling water is 8.4 gallons per minute. i.e

In 1 minute, the amount of water filled = 8.4 gallons.

So, by using the elementary method, in 95 minutes, the amount of water filled = 8.4 x 95 = 798 gallons.

So, the total amount of water in the pool at the end of 95 minutes

=486 + 798 = 1284 gallons.

;Answer:

The answer is below

Step-by-step explanation:

The PTA is trying to raise money for an end of the year carnival for a local

school. They are selling t-shirts, s, for fundraisers. Their revenue equation is

represented by the equation below. As a reminder, the revenue equation

describes how much money is brought in during the fundraiser: r(s) = - .1552 +30s

Their expenses equation is represented by: e(s) = 3s + 200.

A. Find the value of r(s) = e(s)

I

B. Explain what this means in the context of the problem.

Solution:

The revenue is the amount of money gotten by selling goods and products while expenses is the amount of money spent to produce the goods or products.

The revenue is given as:

r(s) = - 0.1552 +30s

While the expenses is given as:

e(s) = 3s + 200.

Since r(s) = e(s), therefore:

3s + 200 = -0.1552 + 30s

30s - 3s = 200 + 0.1552

27s = 200.1552

s = 7.4

s ≈ 7

At break even the expenses and revenue are equal to each other.

This means that if 7 t shirts are produced then the PTA would be at break even.

Explicación paso a paso:

Workdone = Fuerza * distancia movida en la dirección de la fuerza

Dado

Fuerza f = 40N

Distancia = 6 m

El trabajo realizado por la fuerza F es:

Trabajo hecho = 40 * 6

Trabajo terminado = 240 Nm

El trabajo realizado por la fuerza de la gravedad es el trabajo realizado por el cuerpo de 2 kg:

W = mg

W = 2 * 10

W = 20N

Trabajo realizado = 20 * 6

Trabajo terminado = 120 Nm

Step-by-step explanation:

using the graph, we can see that the line goes through points

(0, 5) and (3, -1)

this is all we need

[tex]y = mx + b\\ m = \frac{y_2-y_1}{x_2-x_1} = \frac{5-(-1)}{0-3} = -2[/tex]

[tex]y = mx + b\\5 = -2(0) + b\\b = 5\\y = -2x + 5[/tex]

Answer:

Han had a stronger orange flavor

Step-by-step explanation:

Because he put less water in the mixture.

Answer:

I believe Han's orange juice has a stronger taste of the orange itself. Even though 1/4 is less than 1/3, the amount of water that has been mixed in with the amount of orange juice is less than the 2 1/2. Therefore Clare's is much more diluted with a weaker taste.

Answer: 1/2

Step-by-step explanation:

1. Find the least common denominator (14) and multiply the numerator as much as the denominator

4/14 + 3/14

2. Add the 2 fractions together

4/14 + 3/14 = 7/14

3. Simplify

7/14 divided by 7 = 1/2

The answer is 1/2

Answer:

a + 112 + 33 = 180 ( sum of interior angles of tria

or a + 145 = 180 - ngle is 180 degrees)

or a = 180 - 145

or a = 35 .

similarily,

c + 43 + 71 = 180

or c + 114 = 180

or c = 180 - 114

or c = 66 .

and ,

a + 71 + b = 180 ( sum of angles in straight line is or, 35 +71 + b = 180 180 degrees)

or , b + 106 = 180

or, b = 180 - 106

or, b = 74 .

Thank me later.

p(x) = 2x³ + 3x² + ax + b when divided by x - 2 and x + 2 leaves the remainders 2 , - 2.

Value of a and b

✯ g(x) = x - 2

⟹ 0 = x - 2 [ g(x) = 0 ]

⟹ x = 2

★ p(2) = 2(2)³ + 3(2)² + a(2) + b

⟹ - 2 = 2 * 8 + 3 * 4 + 2a + b

⟹ - 2 - 16 - 12 - 2a = b

⟹ - 30 - 2a = b -- equation (1)

Similarly,

✯ g(x) = x + 2

⟹ 0 = x + 2

⟹ x = - 2

★ p( - 2) = 2( - 2)³ + 3( - 2)² + a ( - 2) + b

Substitute the value of b from equation (1).

⟹ 2 = 2 * ( - 8) + 3 * 4 - 2a - 30 - 2a

⟹ 2a + 2a = - 16 + 12 - 2 - 30

⟹ 4a = - 24

⟹ a = - 24/4

⟹ a = - 6

Substitute the value of a in equation (1).

⟹ - 30 - 2( - 6) = b

⟹ - 30 + 12 = b

⟹ - 18 = b

Therefore,

a = - 6

b = - 18.

I hope it will help you.

Answer:

Step-by-step explanation:

The set up will form a right  angles triangle:

First we need to get the angle of elevation of the first ladder using SOH, CAH, TOA

The length of the ladder will be the hypotenuse = 10foot

The opposite will be the height of the building = 8ft

Using Sin(theta) = opposite/hyp

sin Theta = 8/10

theta = sin^{-1}0.8

theta = 53.13°

If the length of the ladder is now 25 foot, the height of the building will be calculated as shown;

sin Theta = h/25

sin53.13 = h/25

h = 25sin53.13

h = 19.99feet

Hence the height of the building will be 19.99feet

Answer: The third side of the triangle must be greater than the sum of sides 11 and 16.

Step-by-step explanation: "Triangle Inequality Theorem." This theorem states that any side of a triangle must be shorter than the other two sides added together.
