Quadratic equations are the equations that can be re arranged in the linear or the standard form.

<u>Explanation:</u>

In algebra, a quadratic equation is any condition that can be adjusted in standard structure as where x speaks to an unknown, and a, b, and c speak to known numbers, where a ≠ 0. On the off chance that a = 0, at that point the condition is straight, not quadratic, as there is no term.

Quadratic equations are really utilized in regular day to day existence, as while ascertaining regions, deciding an item's benefit or figuring the speed of an article. Quadratic conditions allude to conditions with in any event one squared variable, with the most standard structure being ax² + bx + c = 0.

PLEASE HELP!!!

erastovalidia [21]

Step-by-step explanation:

to write a line equation we need minimum of two points. basicaly a line is written in the form y=mx+c where, m is the slope of the line and c is the intercept made by the line on x-axis (OR) or if two points (x1,y1) and (x2,y2) are given then we can form a line equation as (y-y1)= (y2-y1)*1/(x2-x1) *x-x1 (OR) (y-y2)= (y2-y1)*1/(x2-x1) *x-x2

Guyyysss.. :) Help me solve this geometry problem

Lerok [7]

Answer:

The question asks arc length:

$\frac{ \frac{ \frac{2\pi}{3} }{2\pi} }{1} = \frac{1}{3}$

Dividing by

$2\pi$

Because 360°(by formula)

Therefore:

$\frac{1}{3} \times \frac{2\pi \times 8}{1} = \frac{16\pi}{3 } = 5 \ \frac{\pi}{3} \\ so \: arc \: length \: = \frac{16\pi}{3}$

Good luck!

You randomly draw a marble from a bag of marbles that contains 777 blue marbles, 222 green marbles, and 111 red marble. What is

Kazeer [188]

Answer:

The probability of not drawing blue is 0.3

Step-by-step explanation:

The bag contain a total of:

Blue marbles + green marbles + red marbles

= 777 + 222 + 111

= 1110

We are to find the probability of not drawing a blue marble, if a blue marble is not drawn then the drawn marble is either green or red marbles

P(not draw blue) = p(draw green) + p(draw red)

P(not draw blue) = 222/1110 + 111/1110

P(not draw blue) = 333/1110

P(not draw blue) = 0.3
