What are the coordinates of the vertex of the function f(x) = x2 − 12x + 5?

(6, 31)
(−6, 31)
(6, −31)
(−6, −31)

Answers

Answer 1

Answer:

This means that the coordinates of the vertex of the function are \((6,-31)\)

Step-by-step explanation:

To find the x-coordinate of the vertex of a quadratic function, we can use the formula:

\(x=\frac{-b}{2a}\)

We are given the function \(f(x)=x^2-12x+5\)

In this function, \(a=1\) and \(b=-12\)

Now we can input these values into our formula

\(x=\frac{-(-12)}{2(1)} \\\\x=\frac{12}{2} \\\\x=6\)

This means that the x-value of the vertex is located at \(x=6\). To find the other half of the coordinate pair, we can now plug \(x=6\) into the given function

\(f(6)=(6)^2-12(6)+5\\\\f(6)=36-72+5\\\\f(6)=41-72\\\\f(6)=-31\)

This means that the coordinates of the vertex of the function are \((6,-31)\)

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?

2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100

Answers

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

2 over 8 equals j over 18

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

2 over 8 equals j over 18

Answers

Answer:

Step-by-step explanation:

The discriminant of this equation, i.e, D=\(b^{2}-4ac\) is less than 0:

D= 0-(4*2*18)   --> which is clearly negative

When D is less than 0, the equation has no real number solutions.

So its hard to calculate actual probability without any numbers. But seeing that there are a total of 6 colors on the wheel, and that green is the largest (by a lot since its almost half the wheel) the probability of landing green is very high.

And that's all you can say really...black will be lowest, and yellow seems to be the next highest. In comparison to green though, probability of the other colors will be low.

This figure represents a design that is sewn onto a blanket. The semicircles are a solid green fabric

Answers

Answer:

61%

Step-by-step explanation:

Because there are 4 semicircles, 18/4=4.5, so the area of each semicircle is 4.5 pi. Therefore the area of a whole circle is 9 pi, so the radius of the circle is 3. That means the diameter of the circle, which is also the side of the square, is 6, so the area of the square is 36. Therefore the percent of the design that is green fabric is:

18pi/18pi+36

= 56.52/92.52

= about 0.611, which rounds to 61%.

Answer:

To convert scientific notation to standard form you would need to move the decimal point over the number of the places that the exponent indicates. If the exponent is negative you move the decimal to the left, and if the exponent is positive you move the decimal to the right.

Step-by-step explanation:

1.456*10^3 would be scientific notation.

The exponent is a positive 3, means that you move the decimal 3 places to the right.

1456 would be the standard form.

1.456*10^-3 would be scientific notation.

The exponent is a negative 3, means that you move the decimal 3 places to the left.

0.001456 would be the standard form.
