Answer:
discriminant
Step-by-step explanation:
Discriminant is the expression under the radical in a quadratic equation formula that indicates the nature of the solutions real or complex, rational or irrational , single or double root in other words
A discriminant can be said to be used to indicate the nature of the result that a quadratic equation when solved will yield and this can be : rational or irrational , complex or real, single or double roots. and it also indicates by how many it would be
=sin30cos60 + sin60cos30
=(1/2)(1/2) + (√3/2)(√3/2)
=1/4 + 3/4
=1+3/4
=4/4
=1
Answer:
13/6
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= (6 - -7)/(1 - -5)
= ( 6+7)/ (1+ 5)
= 13/6
