Answer:

The quadrilateral is Parallelogram.

Step-by-step explanation:

A quadrilateral is a four-sided regular polygon.

A parallelogram is a quadrilateral.

The opposite sides of a parallelogram are parallel and equal in length.

The opposite angles of a parallelogram are also equal.

In this case the quadrilateral is defined as follows:

  • two angles that each measure 60°
  • two angles that each measure 120°
  • Only two of the sides have a length of 3.2 inches.

Consider the quadrilateral ABCD below.

The quadrilateral ABCD is Parallelogram.

How many roots does a quadratic have if the discriminant if prime?
scZoUnD [109]

"The discriminant is prime?" I haven't heard that one before.

Here are the general rules:

1. a positive discriminant results in two real, unequal roots.

2. a zero discr. results in two real, equal roots.

3. a negative discr. results in two complex roots, which sometimes means two imaginary roots.

Find the equation of the line through point (5,1) and perpendicular to 5x−y=−3. Use a forward slash (i.e. "/") for fractions (e.
IRINA_888 [86]
Y = -1/5x + 2

A line perpendicular to another line has an opposite reciprocal slope. What opposite means is that you flip the sign (from - to + or from + to -) and reciprocal means that you flip the numerator and denominator (so if line A is perpendicular to line B and line As slope is -3, line Bs slope would be 1/3).

First find the slope of 5x - y = -3
Add y to both sides
5x = y - 3
Add 3 to both sides
y = 5x + 3

So the slope of the line is 5. That means the slope of of the perpendicular line is -1/5.

Plug the slope of the perpendicular line and the point (5, 1) into point slope form to solve the equation

y - y1 = m(x - x1)
y - 1 = -1/5(x - 5)
y - 1 = -1/5x + 1
y = -1/5x + 2
