Answer:

The coordinates of the x-intercepts are;

(-1, 0) and (-11, 0)

The coordinate of the y-intercept is;

(0, 11)

Step-by-step explanation:

The given function is f(x) = x² + 12·x + 11

The x-intercept is at f(x) = 0 which gives;

0 = x² + 12·x + 11 which has been factored as (x + 1)(x+11) such that we have;

(x + 1)(x+11) = 0

x  = -1, or x = -11

The y-intercept occurs at x = 0, we therefore have;

f(0) = (0)² + 12·(0) + 11 = 11

Therefore, we have f(0) = 11 = Y

Given that at the x-intercept, y = 0, then the coordinates of the x-intercepts are;

(-1, 0) and (-11, 0)

Given that at the y-intercept, x = 0, then the coordinate of the y-intercept is;

(0, 11).

Step-by-step explanation:

20 hours divided by 10 hours = 2, so it will be doubled two times.

300 times 2 for the first doubling = 600

600 times 2 for the second doubling = 1200

Answer:

Probability that a customer complains in percentage = 4% (Approx)

Step-by-step explanation:

Given:

Total number of customers = 669

Total number of complaints = 27

Find:

Probability that a customer complains

Computation:

Probability that a customer complains = 27 / 669

Probability that a customer complains in percentage = [27 / 669]100

Probability that a customer complains in percentage = [0.040358]100

Probability that a customer complains in percentage = 4.0358%

Probability that a customer complains in percentage = 4% (Approx)

Answer:

Los números son 6 y 9

Step-by-step explanation:

Este problema se puede resolver por medio de un sistema de ecuaciones.

El primer número será x y el segundo número será y.

Sabemos que los dos números suman 15, por lo tanto esto se puede escribir como:

[tex]x+y=15[/tex]

Por otro lado sabemos que el doble de uno de ellos es igual al otro más 3 unidades, esto lo podemos escribir de la siguiente manera:

[tex]2x=y+3[/tex] (el doble del primero es igual al segundo más 3)

Reescribiendo esta segunda ecuación tenemos:

[tex]2x-y=3[/tex]

Por lo tanto, nuestras dos ecuaciones son:

[tex]x+y=15\\2x-y=3[/tex]

Resolviendo el sistema por el método de reducción observamos que, si sumamos ambas ecuaciones, las y se cancelan y quedamos con:

[tex]3x=18\\x=6[/tex]

Ahora, sustituimos este valor en la primera ecuación para obtener el valor de y:

[tex]x+y=15\\6+y=15\\y=15-6\\y=9[/tex]

Por lo tanto, los números son 6 y 9

Por medio de un sistema de ecuaciones, hay qué los números son 6 y 9.

Los números sumados den 15, o sea:

[tex]x + y = 15[/tex]

El doble de uno de ellos sea igual al otro más 3 unidades, o sea:

[tex]2x = y + 3[/tex]

[tex]y = 2x - 3[/tex]

Reemplazando en la primera ecuación:

[tex]x + y = 15[/tex]

[tex]x + 2x - 3 = 15[/tex]

[tex]3x = 18[/tex]

[tex]x = \frac{18}{3}[/tex]

[tex]x = 6[/tex]

[tex]y = 2x - 3 = 2(6) - 3 = 12 - 3 = 9[/tex]

Los números son 6 y 9.

Answer:

a = -50/51

Step-by-step explanation:

1 + 2a + 3 + 4a + 5 + 6a + ...... + 97 + 98a + 99 + 100a = 0

  1 +   3 +   5 + ...  + 99 +   2a +    4a + ... + 98a + 100a = 0     Eq. 1

99 + 97 + 95 + ... +    1  + 98a + 96a + ... +   4a  +    2a  = 0    Eq. 2

Add Eq. 1 and Eq. 2

100 + 100 + ... + 100 + 102a + 102a + ... 102a = 0

50(100)/2 + 50(102a)/2 = 0

2500 + 2550a = 0

2550a = -2500

a = -2500/2550

a = -250/255

a = -50/51

Answer: 6 or 9

Step-by-step explanation:

Given the following :

Let the number of green pens = x

Number of red pens = x + 3

Probability of picking same color = 17/35

Taking two pens at random; probability of picking two pens of same color.

Probability of picking red on first pick then red on second pick ; or picking blue on first pick then blue on second pick

Probability = (Required outcome / Total possible outcomes)

Total number of pens = x + x + 3 = 2x + 3

Probability of picking red then red:

P(red first) = (x+3)/2x+3

P(red second) = x+3-1 / 2x+3-1 = (x+2)/2x+2)

Therefore, probability of red then red =

(x+3)/(2x+3) × (x+2)/2x+2)

= (x+3)(x+2) / (2x+3)(2x+2)

Probability of green then green:

P(first green) = x/(2x+3)

P(second green) = (x-1) / (2x+3-1) = (x-1) / (2x+2)

P(green then green) = x(x-1)/(2x+3)(2x+2)

Therefore,

[(x+3)(x+2) / (2x+3)(2x+2)] + [x(x-1)/(2x+3)(2x+2)] = 17/35

(x+3)(x+2)+x(x-1) / (2x+3)(2x+2) = 17/35

Cross multiply :

35(x+3)(x+2)+x(x-1) = 17(2x+3)(2x+2)

35(2x^2 + 4x + 6) = 17(4x^2 + 10x + 6)

70x^2 + 140x + 210 = 68x^2 + 170x + 102

70x^2 - 68x^2 + 140x - 170x + 210 - 102 = 0

2x^2 - 30x + 108 = 0

Now we have a quadratic equation which can be factoeized used using any known factorization method.

Factorizing this, we get

(x-6) = 0 or (x-9) = 0

x = 6 or x = 9

Answer:

8:07 am

Step-by-step explanation:

It takes 9 minutes to walk from his house to the bus station.  It then takes 92 minutes for the bus to travel from Birmingham to Coventry.  After arriving, he takes 12 minutes to reach his workplace.  This takes a total of 113 minutes.

9 + 92 + 12 = 113

Convert 113 minutes to hours and minutes.

113 - 60 = 53

1 hr and 53 min

He has to be at work by 10.  Subtract the time it takes to get to his work by the time he has to get there.

10 - 1 hr = 9

9 - 53 min = 8:07

The latest time he can leave is 8:07.

Answer: 6,247,000,000,000

Step-by-step explanation:

Here we have the number:

6.247x10^12 and we want to write this in standard form.

You can see that we have a 10^12, this means that we need to move the decimal dot 12 places to the right, if there is not a decimal to the right, we add a zero.

6.247x10^12 = 62.47x10^11 = 624.7x10^10 = 6,247x10^9 = 62,470x10^8 and so on.

eventually, the standard form is:

6.247x10^12 = 6,247,000,000,000

So we end with 12 digits after the six.

Answer:

Step-by-step explanation:

5x² - 15x - 4 = 0

Add 4 to both sides.

5x² - 15x = 4

The coefficient of 5x² is 5, divide both sides by 5.

x² - 3x = 4/5

The coefficient of -3x is -3. Let b=-3.

Then we need to add (b/2)^2=9/4 to both sides to complete the square.

Add 9/4 to both sides.

x² - 3x + 9/4 = 61/20

Factor left side.

(x-3/2)² = 61/20

Take square root of both sides.

x-3/2 = ± √(61/20)

Add 3/2 to both sides.

x = 3/2 ± √(61/20)

Answer:

Step-by-step explanation:

4y-4=28

4y=28+4

4y=32

y=32/4

y=8

now plug in 8 for y and check the equation true:

4y-4=28

4*(8)-4=28

32-4=28

28=28

So,  y is equal to eight 8

Answer:

y = 8

Step-by-step explanation:

4y - 4 = 28

take -4 to the equal side, which will change and become +4

so, it will be; 4y = 28 + 4

4y = 32

divide both sides by the number next to the unknown(y), which is 4

y = 8

Answer:

The length of the hypotenuse is 8 inches; the length of the longer leg is 4√3 inches.

Step-by-step explanation:

Note that tan 60 degrees = (length of longer leg) / (length of shorter leg), or

                tan 60 degrees = (length of longer leg) / 4 in.

Thus, (length of longer leg) = (4 in)(tan 60 degrees)

                                              = (4 in) [√3/1] = 4√3 in

Also, cos 60 degrees = (adjacent side) / (hypotenuse.  We want to find the hypotenuse and thus solve this equation for it:

(hypotenuse) = (adjacent side) / (cos 60) = (4 in)( 2/1 ) = 8 in

The length of the hypotenuse is 8 inches; the length of the longer leg is 4√3 inches.
