Answer: 20 dallors
Step-by-step explanation:
Answer:
positive
the discriminant of the function is postive.
because from the graph we notice that it has 2 intercepts on x-axis, which means the function has 2 real solution when y=0
that implies the discriminant is positive.
if we have 2 distinct real solution
if we have no real solution but 2 complex solutions
if we have 2 identical real solution
11.64
100%-> 48
15%-> 7.20
6.25%-> 3
48+7.20+3=58.20
58.20÷5=11.64
