How do I rewrite a quadratic into graphing form

Answers

Step-by-step explanation:

Standard form of a quadratic is f(x) = ax² + bx + c.

To convert to vertex form, the simplest method is to find the x-coordinate of the vertex using h = -b/(2a).

Then, plug back into the equation to find the y-coordinate of the vertex.  k = f(h).

Finally, the leading coefficient is the same as the standard form, a.

f(x) = a(x − h)² + k

Another method is to complete the square.

Find the distance between each pair of points (-6,-10) , (-2,-10)

Answers

Answer:

4 units

Step-by-step explanation:

Use the distance formula, d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex], where (x1, y1) and

(x2, y2) are 2 points

Plug in the points given

d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

d = [tex]\sqrt{(-6 + 2)^2 + (-10 + 10)^2}[/tex]

d = [tex]\sqrt{(-4)^2 + (0)^2}[/tex]

d = [tex]\sqrt{16 + 0}[/tex]

d = [tex]\sqrt{16}[/tex]

d = 4

So, the distance between the points is 4 units

The distance between each pair of points (-6,-10) , (-2,-10) is 4 units after using the distance formula.

What is a distance formula?

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

It is given that:

The points are (-6,-10) , (-2,-10)

Using distance formula:

[tex]\rm d=\sqrt{(-2-(-6))^2+(-10-(-10))^2}[/tex]

d = √16

d = 4 units

Thus, the distance between each pair of points (-6,-10) , (-2,-10) is 4 units after using the distance formula.

Randy is four times as old as Kenneth and Randy is 36 years older than Kenneth
i) How old is Kenneth?
ii) How old is Randy?​

Answers

Answer:

Kenneth: 12 years old

Randy: 48 years old

Step-by-step explanation:

For this problem, we can use system of equations to solve. Let's use r for Randy and k for Kenneth.

Equation 1

r=4k

This equation comes from the first part, where Randy is four times as old as Kenneth.

Equation 2

r=36+k

This equation comes from the second part, where Randy is 36 years older than Kenneth.

Since we have r=, we can use substitution method.

4k=36+k                   [subtract both sides by k]

3k=36                       [divide both sides by 3]

k=12

Now that we have found k, we can plug that into any equation to find r.

r=4(12)                      [multiply]

r=48

Now, we know that Randy is 48 years old and Kenneth is 12 years old.

Vertical Angles

Step-by-step explanation:

Vertical Angles are the angles opposite each other when two lines cross.

It is found that angle 2 and angle 1 are vertically opposite angles.

What is vertically opposite angles?

The vertically opposite angles are those angles that are opposite one another at a specific vertex and are created by two straight intersecting lines.

Thus, Each of the pairs of the opposite angles made by two intersecting lines are called vertical angles.

Also, When you slice a given object vertically (perpendicular to the ground level), then the sliced surface is called vertical cross section.

WE have to Classity 2 and 1 using all relationships that apply.

Therefore, we can see that angle 2 and angle 1 are vertically opposite angles.

Find k so that the line through(k-1,k+2) and (4,-1) is perpendicular to the line through (-3,2) and (2,5).

Answers

Answer:

k = 2

Step-by-step explanation:

Perpendicular lines have slopes opposite reciprocal

Formula to find a slope:

m = (y₂-y₁)/(x₂-x₁)

Coordinates of the first line:

(k-1, k+2) and (4, -1)

Coordinates of the second line:

(-3, 2) and (2, 5)

Slopes of the lines:

m₁ = (-1 - k -2)/(4 - k + 1) = - (k + 3)/-(k -5) = (k + 3)/ (k - 5)m₂ = (5 - 2)/ (2 + 3) = 3/5

Since m₁ = - 1/m₂, we have:

(k + 3)/ (k - 5) = - 5/33(k + 3) = -5(k - 5)3k + 9 = - 5k + 253k + 5k = 25 - 98k = 16k = 2

8. Why is it NOT useful to view science as a set of facts?

Answers

Answer:
(assuming this isn't actually for math?) but one reason is bc science shouldn't be always taken as fact. science can be wrong.

Explanation:
not all but many scientists are skeptical and won't accept anything without proof, and even when things are accepted as right they can still be wrong later. example: humans once believed the planets revolved around the earth and that the earth was flat (even, some people still believe the earth is flat today....) but both those things are generally unaccepted today.

science shouldn't be viewed as fact always, because accepting everything as fact will lead to misassumptions and false information. it's like we should never take things for granted

This is my honest opinion

Science is not just facts. Science, to me, is full of theories and hypotheses that can be proved wrong. Yes, a majority of it is actually factual, but in the future it may or may not be true.

I hope it helps.
