Since the angle 240° 240 ° is in the third quadrant, the reference angle formula is Ar=Ac−180°<span> A r = A c </span>- 180 °<span> .</span>
Answer:
A = $100(1.12)^2
Step-by-step explanation:
The standard formula for compound interest is given as;
A = P(1+r/n)^(nt) .....1
Where;
A = final amount/value
P = initial amount/value (principal)
r = rate yearly
n = number of times compounded yearly.
t = time of investment in years
For this case;
P = $100
t = 2years
n = 1
r = 12% = 0.12
Substituting the values, we have;
A = $100(1+0.12)^(2)
A = $100(1.12)^2
Answer:0.80
Step-by-step explanation:please i don't really know how to explain this i am very sorry
Answer: 0.701
Step-by-step explanation:
Formula : 
, where 
significance level , 
Population standard deviation, n= sample size.
As per given, n= 22
Critical z- value for 90% confidence level : 
Then,
Hence , error bound (EBM) of the confidence interval with a 90% confidence level= ± 0.701
As far as I can tell, is just asking for the type, so that'd be a tangential line to the globe, or a tangent line, see picture below
