Please respond using 2-3 COMPLETE sentences. What is the discriminant? What does it tell you about the types of solutions you can have?

The discriminant is just one part of the quadratic formula. It's the part inside of the radical in the quadratic formula( b^2 - 4ac). It tells you if the function has intercept in x axis, if the function has more than one intercept in x axis or if the function has no intercept in x axis.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

the answer is d
