Answer:
Step-by-step explanation:
Let shall be considering the Cosine rule in this situation.
a^2 = b^2+c^2- 2bc.cosA
Where a = ?
b = 21km
c 45km
A = 131
a^2 = 21^2+45^2-2(21*45).cos131
a^2 = 441+2025-1890(-0.6560)
a^2 = 2466+1239.951
a^2 = 3705.951
a= 60.876km
Finding the bearing of the port from the ship.
We shall be considering the Sine rule
Sin A/a = Sin B/b
Where A = ?
a = 45km
B = 131°
b = 60.876km
Sin A/45 = sin131/60.876
SinA×60.876 = 45×sin131
SinA×60.876= 45×0.7547
SinA×60.876 = 33.961
SinA= 33.961/60.876
SinA = 0.5578
A = sin^-1 0.5578
A = 33.9°
Answer:
The population growth rate is <u>59</u> squirrels per year.
Step-by-step explanation:
Given:
A population of squirrels on an island has a carrying capacity of 350 individuals. If the maximum rate of increase is 1.0 per individual per year and the population size is 275.
Now, to find the population growth rate.
Carrying capacity () = 350.
Maximum rate () = 1.0 per individual per year.
Population size () = 275.
Now, to get the population growth rate we put formula:
<u><em>So, rounding to nearest whole number of the population growth rate is 59 squirrels per year.</em></u>
Therefore, the population growth rate is 59 squirrels per year.
It is centered at (h,k) --> (0,0) and has a radius 9
The equation of the circle is
