Estimation is never an effective way to get the answer. But it's always an effective way to determine whether the answer you calculated is reasonable, or from orbit by way of left field.
Answer:
BC = 
=12
Step-by-step explanation:
if the triangle is ABC and have part 12
and right angle from B and have an angle 45 then the third angle is 45 too
then we have another part is 12
and the BC = =12
Answer: He should not be concerned
Step-by-step explanation:
The variation is still the same and has not changed because the only thing that changed are the units. A unit change does not mean that the diameter has changed, only the method of measuring it has changed.
Absolutely speaking, the diameter is still the same. A standard deviation of 0.1 inches is the same as a standard deviation of 2.54mm so the executive should not be worried.
Answer:
0.73 yrs
Step-by-step explanation:
if t is time in years
quarterly
600 = 200(1 + 0.06625/4)^4t
3 = (1 + 0.06625/4)^4t
ln3 = 4tln(1. + 06625/4)
t = ln3 / (4ln1.0165625)
t = 16.7198 yrs
continuously
600 = 200e^(0.06875t)
3 = e^(0.06875t)
ln3 = 0.06875t
t = ln3 / 0.06875
t = 15.9798 years
Δt = 16.7198 - 15.9798 = 0.73 yrs
Answer:
Step-by-step explanation:
n+1/2n=7/2
2n^2+1/2=7/2
4n^2+2=14
4n^2=12
n^2=3
n=radical3
