Answer:
25272 to the 10 power
Step-by-step explanation:
X2 + y2 - 14x + 10y = 250
x2 -14x + 49 - 49 + y2 + 10x + 25 - 25 = 250
(x - 7)^2 - 49 + (y+5)^2 - 25 = 250
(x-7)^2 + (y+5)^2 = 250 + 49 + 25
(x-7)^2 + (y+5)^2 = 324
Therefore the radius, r
r = 324^0.5
r = 18
Number patterns can be formed easily when we know the rule. In our case
The rule is n-4 ,
therefore , when n=1 then 1-4 = -3
n=2 then 2-4 = -2
n = 3 then 3-4 = -1
n = 4 then 4-4 = 0
n = 5 then 5-4 = 1
n= 6 then 6-4 = 2
Therefore we get a pattern -3,-2,-1,0,1,2,..............
hence in this case the difference between consecutive pairs is always 1
23/198 that is the simplified version
Answer:
option B
Step-by-step explanation:
given,
3-month T-bill currently yields = 3%
customer price have been rising = 2% rate
Ai Lun's estimate of the real rate = ?
real rate return
= 
= 
= 
= 
= 0.0098
= 0.98 % ≅ 1 %
hence, the correct answer is option B
