Describe how to find the distance between two points on the coordinate plane.

zheka24 [161]

Answer: Dist = 8.94, midpoint = (1,6)

Step-by-step explanation:

Basically, the Distance between the points is the hypotenuse of a right triangle, whose legs are parallel to the x and y axes.

Leg 1 = x2 - x1 = 5 - -3 = 8

Leg 2 = y2 - y1 = 8-4 = 4

Hypotenuse = (8^2 + 4 ^2) ^ .5 = (64+16)^.5

Sqrt(80) = 8.94

The midpoint is aligned with the midpoint of each leg

X = 5 - 8/2 = 1

Y = 8 - 4/2 = 6

So (1,6) is the midpoint

What is the factored form of x2 – x – 2? (x – 2)(x 1) (x 2)(x 1) (x – 2)(x – 1) (x 2)(x – 1)

Alexxx [7]

A quadratic equation is an equation whose leading coefficient is of the second degree. The factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

<h3>What is a quadratic equation?</h3>

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.

It is written in the form of ax²+bx+c.

The factored form of the quadratic equation can be done in the following manner,

$x^2-x-2\\\\= x^2-2x+x-2\\\\=x(x-2)+(x-2)\\\\=(x+1)(x-2)$

Thus, the factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

. In Habib High School 275 of 300 students received a grade of A, while in Public Hall 120 out of 150 students received a grade

nevsk [136]

Habib High School had the better record. If we convert 275/300 and 120/150 to fractions Habib High School would have 0.92 percent when compared to 0.80 of Public Hall.
