1. a triangle has the base of 5/3x and the height of x<br> how do i work this equation

sashaice [31]

Answer:

Area = 5/6 * x^2

Step-by-step explanation:

If you are given the base and height of a certain triangle, you will most likely be asked to find the area

The area of any triangle can be found by

Area = base*height * (1/2)

In your case

Area = (5/3)*x*x* (1/2) = 5/6 * x^2

In your case, x should be a known parameter of your triangle, so if you have the value of the height, you should be able to find the area. Or conversely, if you have the area, you can find the length and height of your triangle.

Which is the graph of a quadratic equation that has a negative discriminant?

vovikov84 [41]

Answer:

Here's what I get

Step-by-step explanation:

The formula for a quadratic equation is

ax² + bx + c = 0

The quadratic formula gives the roots:

$x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a} = \dfrac{-b\pm\sqrt{D}}{2a}$

D is the discriminant.

It tells us the number of roots to the equation — the number of times the graph crosses the x-axis.

$D = \begin{cases}\text{positive} & \quad \text{2 real solutions}\\\text{zero} & \quad \text{1 real solution}\\\text{negative} & \quad \text{0 real solutions}\\\end{cases}$
