Answer:
Option B. 
Step-by-step explanation:
we know that
If a ordered pair lie on the circle. then the ordered pair must satisfy the equation of the circle
step 1
Find the equation of the circle
we know that
The equation of the circle in center radius form is equal to

where
r is the radius of the circle
(h,k) is the center of the circle
substitute the values


step 2
Verify each case
case A) 
substitute the value of
in the equation of the circle and then compare the results

------> is not true
therefore
the ordered pair Q not lie on the circle
case B) 
substitute the value of
in the equation of the circle and then compare the results

------> is true
therefore
the ordered pair R lie on the circle
case C) 
substitute the value of
in the equation of the circle and then compare the results

------> is not true
therefore
the ordered pair S not lie on the circle
case D) 
substitute the value of
in the equation of the circle and then compare the results

------> is not true
therefore
the ordered pair T not lie on the circle
Answer: The amount of money in his account after 4 years = $7,658.73
Step-by-step explanation:
If interest is compounded annually, then formula to compute amount :
, where P+ principal value, r= rate of interest, n= time ( in years).
As per given,
P= $6700 , r = 3.4% =0.034, n =4

Hence, the amount of money in his account after 4 years = $7,658.73
Step-by-step explanation:
2⁶X5⁴X3¹²/2²x5²x3⁴
2⁴ × 5²×3⁸
A) Yes. we don't have enough information so this can not be determined.
B) No, it would just be an outlier.
