The formula to finding a discriminant would be b^2-4ac, the b value of this trinomial being -5, the a value being 2, the c value being 3. Then, you plug the values in the equation and solve: (-5)^2-4(2)(3)
This would simplify to 1, meaning there are two solutions since the discriminant value is positive. If it is 0, there is one solution, if it is negative, then there are no real solutions.

You should be able to find this

Nastasia [14]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

sin( $cos^{-1}$ $\frac{\sqrt{3} }{2}$ )

using the sides of the 30- 60- 90 triangle

with legs 1, $\sqrt{3}$ and hypotenuse 2 , then

$cos^{-1}$ $\frac{\sqrt{3} }{2}$ = 30° and

sin30° = $\frac{1}{2}$

I think it’s c but I need help

Answer:

x = 12

Step-by-step explanation:

In a right triangle (a triangle that has a ninety degree angle in it) the the square of the side opposite the right angle is always equal to the sum of the squares of the other two sides. Therefore, we can use the information we are given to figure out the missing side:

$15^2=225\\9^2=81\\225-81=144\\\sqrt[2]{144}=12$
