what are the steps to convert a quadratic function in standard form to vertex form
Answers
Alternately, you can calculate the value for the vertex as such using this formula for the ordered pair: [tex]( \frac{-b}{2a}, f(\frac{-b}{2a}))[/tex]. Then, you can plug this point in for [tex](h, k)[/tex].
To convert a quadratic function in standard form to vertex form, follow these steps: identify the given equation, find the x-coordinate of the vertex, substitute the x-coordinate to find the y-coordinate, and write the function in vertex form.
Explanation:To convert a quadratic function in standard form to vertex form, follow these steps:
Identify the given equation in standard form, which is in the form of ax² + bx + c = 0.Use the formula x = -b/2a to find the x-coordinate of the vertex.Substitute the found x-coordinate into the original equation to find the y-coordinate of the vertex.Write the quadratic function in vertex form as y = a(x-h)² + k, where (h, k) is the vertex of the parabola.For example, if the quadratic function is given as 2x² - 8x + 5 = 0, we first find the x-coordinate of the vertex using the formula x = -b/2a as x = -(-8)/(2*2) = 2. Substituting this x-coordinate into the equation, we find the y-coordinate of the vertex as y = 2*(2)² - 8*(2) + 5 = -3. Therefore, the quadratic function in vertex form is y = 2(x-2)² - 3.

What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
LMN is a triangle shown in figure.
Now,
Here, LMN is a triangle shown in figure.
By definition of proportionality, we get;
⇒ x / 15 = (20 + x) / (15 + 18)
Solve for x as;
⇒ x / 15 = (20 + x) / 33
⇒ 33x = 15 (20 + x)
⇒ 33x = 300 + 15x
⇒ 33x - 15x = 300
⇒ 18x = 300
⇒ x = 300/18
⇒ x = 50/6
⇒ x = 16 2/3
Thus, The value of x will be 16 2/3.

A scale factor is a term that defines the multiplicative/divisive measurement difference between the two same shapes. The way we can find our scale factor is by dividing our new measurement by the old measurement.
681 / 3 = 227
Our scale factor is 1/227, as 3 is 1/227 of 681 - and we are looking for the scale factor to find what multiplied by 681 would give us 3.

6x-2y=24
Notice that -2y appears in both equations. Multiply the first equation by -1, obtaining
5x + 2y = -2 and then adding the second equation to this result:
6x -2t = 24
-----------------
11x = 22, so x = 2. Now subst. 2 for x in either of the original equations to find the value of y.
6(2) - 2y = 2 becomes 2y = 12-2, or 2y = 10, or y = 5.

A circuit board manufacturer can produce 2,000 boards per hour. How many days will it take to produce 16,500 if the company has a 10 hour work shift? How many days will it take to produce 16,500?
Answers
OK so 2,000 boards per hour in 10 hours is 2,000*10=20,000 boards in 10 hours. So it can produce 16,500 boards in less than a day.
I may be wrong but I hope this helps!
Answer:
it will take less than one day.
Step-by-step explanation:
A circuit board manufacturer can produce 2,000 boards per hour.
If the company has a 10 hour work shift.
manufacturer can produce in one day = 2000 × 10 = 20,000
To produce 16,500 boards, they need time = 16,500 ÷ 2000 = 8.25 hours
The company will take to produce 16,500 boards in 8.25 hours less than one day.
