Radio signals travel at a rate of 3x10^8 meters per second. how many seconds will it take for a radio signal to travel from a satellite to the surface of the earth if the satellite is orbiting at a height of 7.5x10^6 meters?
i dont know
convert from yards to feet 5070×3=15210
(-2, 5), (-2, -19), (5.2, 2.6)
you can add ±12 to either the x- or the y-coordinate, as was done in the first two answers above.
or, you can figure the side lengths of a triangle with hypotenuse 12 and add those to the coordinates. for example, a 3-4-5 right triangle multiplied by 2.4 will have side lengths of 7.2, 9.6 and a hypotenuse of 12. hence we can find one of your end points to be
(-2+7.2, -7+9.6) = (5.2, 2.6)
well, 31/2 is in simplified form
the mixed number form is 15 1/2
and the decimal form would be 15.5
