What is the discriminant. Y=4x2+6x+3

-12

Step-by-step explanation:

y=4x²+6x+3

The discriminant:

Delta=6²-4×4×3=36-48=-12

We have , that corresponds to the form of parabola . The discriminant of a parabola is defined by formula . Inserting numbers into the formula we get that discriminant is .

Hope this helps.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
