1) From building 1 to 2: 5 - (-3) = 8
2) From 2 to 3: 4 - (-5) = 9
3) From 3 to 4: 5 - (-3) = 8
4) From 4 to 1: 4 - (-5) = 9
Total: 8 + 9 + 8 + 9 = 34 units = 34*100 feet = 3400 feet.
Answer: 3400 feet
Ok so there is a kinda simple way to do this and that is by dividing when you divide you get 450.826... so the fan spins about 450 times hope that this helps you
Answer:
Step-by-step explanation:
from the equation, 
.
we can give different approach to the equation, but to make it simple and direct, let separate the equation by bringing all like terms to the same side i.e
.
if we integrate both side,
since the equation passes through the origin, and at the origin z=0 and t=0
we substitute this values and solve for the constant c
.
If we substitute the value of c into the equation we arrive at
if we the the natural logarithm of both sides, we arrive at
3 is the answer to your question
Answer:
(0.1753 ; 0.2447)
Step-by-step explanation:
Using the relation :
Confidence interval :
p ± margin of error
p = 0.21
1 - p = 0.79
n = 530
Zcritical at 95% confidence level = 1.96
Margin of Error : Zcritical * sqrt[(p(1-p))/n]
1.96 * sqrt[(0.21(0.79))/530]
1.96 * 0.0176923 = 0.0346769
Margin of Error = 0.0346769
Lower boundary = 0.21 - 0.0347 = 0.1753
Upper boundary = 0.21 + 0.0347 = 0.2447
Confidence interval :
(0.1753 ; 0.2447)
