To calculate this you need to imagine triangle which points are:
boat
Top of lighthouse
Bottom of lighthouse
That triangle has 90 degrees angle at bottom of lighthouse. That means that we can use trigonometry to determine length between boat and bottom of lighthouse
tan(25) = 89/x
x = 89/tan(25)
x = 190.86
after rounding, the answer is D, 191 feet
Answer:
0.865
Step-by-step explanation:
To solve for the probability we would be using the formula:
F(x) = 1 - e^−λx
Therefore, P(x > 2000) = F(x) = 1 - e^−λx
Mean = 1000 hours
λ = 1/mean = 1/1000 hours
x= 2000 hours
F(x) = 1 - e^−(1/1000)2000
F(x) = 1 - e^−2
= 0.8646647168
Therefore, the probability the the circuit will last at least 2000 hours = 0.865
Answer:
Step-by-step explanation:
36 : 3 = 12
12 : 3 = 4
...
4/3 : 3 = 4/
Answer:
Equation: y(1.09)^x
After 10 years there will be about 12 squirrels.
Step-by-step explanation:
y(1.09)^x
=5(1.09)^10
=(approx.) 12 squirrels
Well it seems if you round you would get 1.81 try it
