Two radio transmitters positioned 200200 mi apart along the shore send simultaneous signals to a ship that is 100100 mi offshore and sailing parallel to the shoreline. The signal from transmitter S reaches the ship 500500 microseconds later than the signal from transmitter T. The signals travel at a speed of 186,000 miles per second, or 0.186 mile per microsecond. Find the equation of the hyperbola with foci S and T on which the ship is located. (Hint: For any point on the hyperbola, the absolute value of the difference of its distances from the foci is 2a.)
step-by-step explanation:
a'(12.5,11.25)
slope=(y1-y2)/(x1-x2)
5x+40
5(x + 8)
7x - 49
7(x - 7)
18x + 9
9(2x + 1)
15x - 10
5(3x - 2)
step-by-step explanation:
for number one all you have to do is factor 5 out of 5x + 40
for number 2 factor 7 out of 7x - 49
for number three factor 9 out of 18x + 9
for number four factor 5 out of 15x - 10
combine all like terms then its just a 2 step equation
180-142=38 for the acute angle next to the entry
90+38=128
180-128=52
a=52
