4 An electric lightbulb operates for 1 hour and 15 minutes. What is the total time the
bulb operates in seconds? * m
(10 Points)
4.5x 10-1s
4.5 x 10-15
4.5× 10² s
4.5 x 10²5
4.5 x 10's

0.55x745.7j and a calculator

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
