Answer:
B/second option
Step-by-step explanation:
The first option is wrong because you make 30 meatballs in 30 mins but then 30 meatballs in 20 mins. If it was constant then in 20 mins you make less meatballs.
The last option is wrong because if bacteria triples, then that is exponential, not constant change.
Only the middle option makes sense. The rate of change is $35 for each hour!

Answer:
a=2,b=-3 and c=-2
Step-by-step explanation:
(2x+1)(x-2)=0
2x²-4x+x-2=0
2x²-3x-2=0
Comparing it with the standard form of quadratic equation ax²+bx+c=0 we get
a=2,b=-3 and c=-2

Answer:
Step-by-step explanation:
Equation of a circle:
The standard equation of a circle with center 
is given by:
In which r is the radius.
Center (– 10, –3)
This means that 
. So
Passes through the point (-3,3).
This means that we use 
to find the radius squared. So
The equation of the circle is:
