Need Help In These word problems
Let Me know if u have any problem reading it.
Ok so for question 9 i got this
a:0 show swimming distance is given by relationd d=wsecx
if l=2w determine the range of values that x may take on given that P can anywhere along the length of pool. so i tried these
cosx=w/d will not work
sinx=2w/d will not work
tanx=2 inverse therefore
0<x<1.07, is this right?
C) im stuck in this question! please help any hints?
D) I think i know how to do once i figured out c?
E) same as D
For question 10, im just confused any hints is appreciated :D
Soln. to question 10 (a,b and d).
(10a) line d // horizontal. Hence x = angle on the top right in the triangle, since alternate angles are equal.
Refer to the diagram in the question. When x approaches 0, then the window would get full sunlight (no shade). When x approaches pi/2, i.e. 90 degrees, then the window will get no sunlight (full shade). I hope this is correct.
