How to find the maximum or minimum value of a quadratic function?

Answers

The maximum or minimum of a quadratic function is found evaluating the polynomial at [tex]x = -\frac{b}{2\cdot a}[/tex].

A quadratic function is an algebraic function of the form:

[tex]y = a\cdot x^{2}+b\cdot x + c[/tex], [tex]\forall \,x, y, a, b, c\,\in \mathbb{R}[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.[tex]y[/tex] - Dependent variable. [tex]a,\,b,\,c[/tex] - Coefficients.

The maximum/minimum of a quadratic function is represented graphically by the vertex, which is the only point that has no a "twin" point by any means of symmetry. We can get the x-coordinate of the vertex by means of the quadratic formula:

[tex]a\cdot x^{2} + b\cdot x + (c- y) = 0[/tex] (2)

[tex]x = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot (c-y)}}{2\cdot a}[/tex], where [tex]b^{2}-4\cdot a\cdot (c-y) = 0[/tex].

Hence, the x-coordinate of the vertex is:

[tex]x = -\frac{b}{2\cdot a}[/tex] (3)

And the y-coordinate of the vertex is determined by evaluating (1) at (3):

[tex]y = f\left(-\frac{b}{2\cdot a} \right)[/tex] (4)

The maximum or minimum of a quadratic function is found evaluating the polynomial at [tex]x = -\frac{b}{2\cdot a}[/tex].

what is the slope of a line b perpendicular to line a with equation y=7x-9

Answers

Answer:

The slope of line b would be -1/7.

Step-by-step explanation:

This happens because if you have the slope of any line and are trying to find the perpendicular line to said line, the slope of the perpendicular line will always be the opposite reciprocal of the original slope.

Then, all you need to do is find some points and graph the lines.

prove that 5^(2n - 1) is divisible by 8​

Answers

Answer:

Step-by-step explanation:

Prove that 52n − 1 is divisible by 8 for all n ∈ N.

Solution

To prove by induction, we must

1. Show it is true for n = 1

2. Assume true for n and prove it is true for n + 1.

Let P(n) be the statement 52n − 1 is divisible by 8.

When n = 1, 52 − 1 = 24, which is divisible by 8.

This proves P(1).

Suppose that P(n) is true, i.e., 52n − 1 is divisible by 8.

Then 52(n+1) − 1 = 52

· 5

2n − 1 = 52

(52n − 1) + (52 − 1).

Note that 52n −1 is divisible by 8 using P(n) and also 52 −1 = 24 is divisible

by 8. Thus we have proved that P(n + 1) is true.

We conclude that P(n) is true for all n ∈ N.

Answers

Answer:

Hope this helps

Step-by-step explanation:

Mathmagic Land had taught me more about math that I never knew before. I learned that everything can be involved with math. It all starts at the Pythagoreans which were the Greek. An example of how math is used today, is by playing billiards.

In billiards, you have to have a good technique of how your going to hit the ball, (good angles,) and you have to have a precise calculation of the angle your going to hit it at.I also learned when you cut shapes like a sphere, it just makes more and more shapes.

This is what I learned watching the Mathmagic Land Video.

A cricket bat is bought for $400. Later, it is sold with a loss of 15%. How much is the cricket bat sold for? =

After selling the cricket bat, how much money has been lost? Give your answer to two decimal places because it is a currency.=

Answers

15% of 400 is 60 so
400 minus 60 is 384
so The bat was sold for 384 but 384 in currency is 329.94

Answer:

$340.00

Step-by-step explanation:

What I like to do first is find 10% of the number.

So 10% of 400 would be $40.

Then find half (5%) of the 10% ($40), which would be $20.

Add the $40 + $20 to get $60.

Then take $400 and subtract $60,

which gives you $340.00

m=⅓


m=-3


m=3


m=-⅓

Answers

Answer:  Slope of the line formed by the data is -3.  

m=-3    for    y=mx+b.

Step-by-step explanation:  The slope is the change in y (the rise) divided by the change in x (the run) between two points on the line.  I'll pick 2 points:  (-4,17) and (9,-22).  Any two points will work, if it is a straight line.  For these points, y, the rise, changes from 17 to -22, for a net change of (-22 - 17) = -39 for y.  x, the run, goes from -4 to 9, for a change in x of (9 - (-4)) = 13.

The rise(y) over the run(x) for these points is thus (-39/13) = -3

The slope is -3

The Rise of Jim CrowAlthough it failed, the Populist movement and other multi-racial efforts made the white Southern elite afraid that the poor whites and Blacks might unite to challenge the power of the plantation owners. So, in all Southern states, various laws were passed by white Southern legislatures to segregate split up Blacks and whites in Southern society. This system of segregation was nicknamed Jim Crow after a popular song and dance routine by a white man making fun of Black people.The laws were very extensive. Blacks and whites were forbidden from marrying each other. Blacks and whites had to have separate toilets, separate park benches, separate drinking fountains and restaurants. Blacks on streetcars (and later buses) were forced to sit in back and give up their seats if white passengers needed them. Of course, whites and Blacks had separate schools. The Supreme Court endorsed this segregation in the case of Plessy v. Ferguson, saying segregation was fine as long as it was separate but equal. But it was never equal. Black schools were always given less resources and less funding. Black toilets and drinking fountains were always of lesser quality. If a business could not afford separate services, they simply refused to serve Blacks. Blacks were barred from white restaurants, shops, hotels. At gas stations, Black people had to go into the woods to relieve themselves because they were not allowed to use the toilets. It was humiliating to Black people and meant to be.And it was clear that the main purpose of this segregation was not just humiliation but making sure that Blacks and whites lived in separate social circles so they would not unite as workers or as poor people. All meetings, concerts, and church services were segregated by law. A Tennessee law even forbid Blacks and whites from playing checkers together. Obviously, they had to pass these laws because Blacks and whites were mixing in these ways and it had to be stopped because if they mixed socially, poor whites and Blacks could unite politically against the wealthy elite. This situation made it difficult to form labor unions, hold strikes or demand better wages and working conditions in the South. Up until this day, the former Confederacy is the poorest part of the country. Welfare payments are the lowest. Services are the weakest. But taxes for the rich are also the lowest. This was the real purpose of Jim Crow. And although segregation itself ended after the Civil Rights Movement in the 1960s, the effects of this racist system remain today.1. What was Jim Crow?2.
