Answer:
Option C. positive
Step-by-step explanation:
we know that
If the discriminant of a quadratic function is positive, then the quadratic function has two real solutions
If the discriminant of a quadratic function is zero, then the quadratic function has one real solution
If the discriminant of a quadratic function is negative, then the quadratic function has two complex solutions
In this problem
The quadratic function has two real solutions (x-intercepts)
therefore
The discriminant is positive
Cos D = adjacent of angle D/ Hypotenus
=33/65
Answer:
18 is the correct answer
Step-by-step explanation:
to find f(6) you only need to put value 6 in place x and then simple addotion subtraction
f(6)=4(6)-6
f(6)=24-6
f(6)=18
