Answer:
C
Step-by-step explanation:
a=12,b= 9, c=7
x=-9±√9²-4x12x7/2x12
=-9±√81-336/24
=-9±√-225/24
{x=9+í√225/24 or x=9-í√225/24}
The correct solution is n=3
Answer:
The 12000 City would become 22,986 people, while the 230,000 city would become a population of 124,223.
Step-by-step explanation:
1st Part:
=12000⋅(0.026000000000000002⋅25)
=12000(2.718281828459045)(0.65)
=22986
2nd Part:
=230000⋅(−0.044000000000000004⋅14)
=230000(2.718281828459045)(−0.616)
=124223
Answer:
1. 6pi or 18.84cm
2. 20pi or 62.8cm
3. 13pi or 40.82cm
4. 9.5pi or 29.83cm
5. You calculate the circumference of a circle with the expression 2pi(r). r stands for the radius. You can also use pi(d), or pi x diameter.
7. You would use 2pi(r) to find the circumference of a circle when given the value of the circle's radius.
8. You would use pi(d) to find the circumference of a circle when given the value of the circle's diameter.
