Answer:
Step-by-step explanation:
average of x-coordinates = (7+1)/2 = 4
average of y-coordinates = (-3-1)/2 = -2
center of circle: (4,-2)
radius = distance between (1,-1) and (4,-2)
= √((4-1)²+(-2-(-1))²)
= √10
equation of circle:
(x-4)² + (y+2)² = 10

Answer:
Part A) Annual
Part B) Semiannual
Part C) Monthly
Part D) Daily
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
so
Part A) Annual
in this problem we have
substitute in the formula above
Part B) Semiannual
in this problem we have
substitute in the formula above
Part C) Monthly
in this problem we have
substitute in the formula above
Part D) Daily
in this problem we have
substitute in the formula above
6/15=2/c
Cross multiplications.
15*2=30
6*c=6c
6c=30
divide.
c=5
