If f(x) = -(5)x , what is f(2)?

Answer:

Step-by-step explanation:

y = (x² - 8x) + 10

Complete the square

 coefficient of the x term: -8

 divide it in half: -4

 square it: (-4)² = 4²

 use 4² to complete the square and keep the equation balanced:

y = (x²-8x + 4²) - 4² + 10

y = (x-4)² - 6

Answer:

y = (x - 4)² - 6

Step-by-step explanation:

use the 'completing the square' method:

x² - 8x + 10 = 0

x² - 8x + 16 = -10 + 16

(x - 4)² = 6

y = (x - 4)² - 6

Answer:

68.30200

Step-by-step explanation:

The exact quotient of 68,302 ÷ 1000 is 68.302.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

68,302 ÷ 1000

= 68,302 / 1000

= 68.302

Thus,

The quotient is 68.302.

Answer:

John sells candy at the lowest price.

Step-by-step explanation:

If John sells 6 candies at 10$, then that's what's called a ratio between the price and the candy. We can double the amount of candy and the price to $20 for each 12 candies, $30 for 24, $40 for 36, etc. But it would still maintain the ratio of 6 candies for each 10$. Adam however, sells candy at 13 pieces for $20. We can divide the ratio down to 6.5 candies for 10$. But since we "can't" split a candy in half, we'll round it to 7 pieces for 10$, which costs more than 6 for 10$: Therefore, John sells candy at the lower price.

Answer:

a) 26.79%, b) 50.42% and c) 22.79%

Step-by-step explanation:

a. What is the probability that both Dave and Mike will show up?

As decisions of showing up can be assumed to be independent, the probability will be given by

(1-0.53)(1-0.43)=(0.47)(0.57)=0.2679=26.79%

b. What is the probability that at least one of them will show up?

There are two possibilities for this to happen:

Dave shows up but Mike does not. The probability of Dave to show up is (1-0.53)=0.47 and the probability that Mike does not is 0.43. Then, as these events are independent, the probability for both of them to happen is (0.47)(0.43)=0.2021=20.21%

Mike shows up but Dave does not. The probability of Mike to show up is (1-0.43)=0.57 and the probability that Mike does not is 0.53. Then, as these events are independent, the probability for both of them to happen is (0.57)(0.53)=0.3021=30.21%

Therefore, the probability that at least one of them will show up? is 20.21%+30.21%=50.42%.

c. What is the probability that neither Dave nor Mike will show up?

As decisions of showing up can be assumed to be independent, the probability will be given by

(0.53)(0.43)=0.2279=22.79%

Given:

The table for a linear function.

To find:

The equation of the linear function.

Solution:

If a linear function passes through two points, then the equation of linear function is:

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Consider any two points from the given table. Let the two points are (2,-2) and (4,0). So, the equation of linear function is

[tex]y-(-2)=\dfrac{0-(-2)}{4-2}(x-2)[/tex]

[tex]y+2=\dfrac{2}{2}(x-2)[/tex]

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

Subtracting 2 from both sides.

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

[tex]y=x-4[/tex]

So, Ethan 's made a mistake. The sign between x and 4 must be negative but in Ethan's equation it is a positive sign, which is not correct.

Therefore, the required linear equation is [tex]y=x-4[/tex].

v=pi*r^2h

Answer:

5626.9m³

Step-by-step explanation:

V = πr²h

radius = 8

height = 28

to make it easier first step is to get the multiply the radius and the height but first multiple the radius by itself

=> 8 x 8 = 64

=> 64 x 28 = 1792

then multiply 1792 by π (3.14)

=> 1792 x 3.14 = 5626.88

when you round the answer it will be 5626.9

Answer:

She should use the formula [tex]C = \pi d[/tex] to find a diameter of 16 inches.

Step-by-step explanation:

The circunference of a circle is given by:

[tex]C = 2\pi r[/tex]

In which r is the radius, which is half the diameter. So, it can also be given by the following formula:

[tex]C = 2\pi \frac{d}{2} = \pi d[/tex]

In which d is the diameter.

Which formula should Maria use to help her find the diameter of the rug?

She should use this formula:

[tex]C = \pi d[/tex]

Since the circunference is 50.24 inches, the diameter will be of:

[tex]d = \frac{C}{\pi} = \frac{50.24}{\pi} = 16[/tex]
