Points A and B are the end points and C is somewhere between them.

In order to find the total length of AB, you would add CA and CB together.

The answer would be C. CA

Here we are given that C is between A and B.

So using the midpoint rule, sum of whole length AB will be addition of lengths AC and BC

so we can say that option C. CA is the correct choice as it satisfies the given condition.

If the discriminant of a quadratic equation is equal to -8, which statement describes the roots?

Dovator [93]

Keywords

quadratic equation, discriminant, complex roots, real roots

we know that

The formula to calculate the roots of the quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}}{2a}$

where

The discriminant of the quadratic equation is equal to

$b^{2}-4ac$

if $(b^{2}-4ac)> 0$ ----> the quadratic equation has two real roots

if $(b^{2}-4ac)=0$ ----> the quadratic equation has one real root

if $(b^{2}-4ac)< 0$ ----> the quadratic equation has two complex roots

in this problem we have that

the discriminant is equal to $-8$

the quadratic equation has two complex roots

therefore

the answer is the option A

There are two complex roots

The base area of a prism is 140 square feet. Its height is 6 feet. What is the volume of the prism? A. 280 ft3 B. 840 ft3 C. 420

MakcuM [25]

You already have the base area, so to work out the volume, you just multiply 140 by 6.

Therefore, the answer is B. 840 ft³ :)
