Triangle PDQ has:
Side "p" is opposite Angle P
Side "d" is opposite Angle D = 45º + 23º = 68º
Side "q" is opposite Angle Q
Use the Law of Cosines:
d² = p² + q² − 2 • p • q • cos(D)
d² = (4.24)² + (4.24)² − 2 • (4.24) • (4.24) • cos(68º)
d² = 2(4.24)² − 2(4.24)² • cos(68º)
d² = 2(4.24)² • [ 1 – cos(68º) ]
<span> d = 4.74 ft

Csc (3pi/2) = 1/sin(3pi/2)
According to the graph sin(3pi/2) = -1
So,
csc (3pi/2) = 1/(sin(3pi/2) = 1/(-1) = -1
The answer is -1
Answer:
-15 plus or minus the square root of 65 all over 4 (All over means fraction)
We know
In a function
x represents the input and y represents output
So
x is time
So
f(30) represents distance traveled in 30mins
