The length of the island will be given as follows:
tan θ=opposite/adjacent
thus:
tan75.8= 3000/a1
a1=3000tan75.8
a1=11855.885 ft

also:
tan15.6=3000/a2
a2=3000tan15.6
a2=837.62 ft
Thus the length of the island will be:
11855.885-837.615
=11,018.24 ft

Determine whether or not f is a conservative vector field. if it is, find a function f such that f = ∇
olga nikolaevna [1]
F =del F, make the distinction its 2 different functions

in this case its a conservative vec field
u can do Del x F or curl F and see its not 0, but anyway, u can also integrate the portion in i wrt to x and portion in j component wrt to y, and see that even with the constants being functions of the variable not being integrated wrt to, you still cannot find a function g such that f(x,y)=del (g)

Anyone know how to find the missing length ?
Svet_ta [14]

Answer:

so i'm assuming you'd use Pythagoras:

so 15^2-12^2=81

square root it=9 which is I

to find T we do 41^2-9^2=1600

square root that is 40 so T=40

Find the annual percentage yield (APY) in the following situation,
netineya [11]

Answer:

3.95%

Step-by-step explanation:

An interest-bearing account paying a stated nominal or annual interest rate of 3.880% compounded monthly, would translate to an Annual Percentage Yield (APY) or Effective Annual Rate (EAR) of 3.95%. This means that $100.00 will grow to $103.95 ($103.95 rounded) after one year.
