R=2.1
Diameter would be half of that
Answer: c= $( 5 x 5.20)
Step-by-step explanation:
Given: Total people =5
Money paid by each person = $5.20
Total cost of the sundae = (Number of people ) x (Money paid by each person)
Total cost of sunday : c= 5 x ($5.20)
i.e.Total cost of sunday = $(5 x 5.20)
i.e.Total cost of sunday = $ 26
Hence, the required equation to represent the total cost (c) of the sundae:
c= $( 5 x 5.20)
Answer:
The discriminant of ax^2+bx+c is b^2-4ac.
If the discriminant, d, is:
d<0, there are no real solutions (there are two imaginary solutions however)
d=0, there is one real solution
d>0, there are two real solutions
In this case d=16-32=-16 so there are two imaginary solutions. Or from your answer choices, it can be said that there are no real number solutions becuse the discriminant is less than zero.
