Answer:
The rate of change of the tracking angle is 0.05599 rad/sec
Step-by-step explanation:
Here the ship is traveling at 15 mi/hr north east and
Port to Radar station = 2 miles
Distance traveled by the ship in 30 minutes = 0.5 * 15 = 7.5 miles
Therefore the ship, port and radar makes a triangle with sides
2, 7.5 and x
The value of x is gotten from cosine rule as follows
x² = 2² + 7.5² - 2*2*7.5*cos(45) = 39.04
x = 6.25 miles
By sine rule we have
Therefore,
α = Angle between radar and ship α
∴ α = 58.052
Where we put
to get
and differentiate to get
= 3.208 degrees/second = 0.05599 rad/sec.
Answer:
she is left with 4.67 LB of flour.
Step-by-step explanation:
7 divided by 3 = 2.3333333
2.3333333 x 2 = 4.67
let, the height be h
area of the parallelogram= base x height
425 = 35 x h
425/35 = h
12.14m = h
Answer:
Step-by-step explanRemember: logax=b⇒ab=x
in which "a" is the base of the log.
log4 (1/16) = 4^-2 = 1/4^2 = 1/16
4 to the power of -2 is equal to 1/16.
To answer this question, the equation in exponential form of "log4 (1/16) = -2" is " 4^-2 " (4 to the power of -2). :D
