answer: cos [ arcsin (3/5) - arccos (1/2) ] =
step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg
cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13
b. cos (36.87 - 60) = cos (-23.23) = 0.92
45.36 feet per second.
to find the most accurate determination for the number of feet per second tyrone traveled on his way to work let us convert miles to feet and minutes to seconds.
1 mile = 5280 feet.
1 minute = 60 seconds.
now we will divide 158400 by 3492 to find the most accurate determination for the number of feet per second tyrone traveled on his way to work.
therefore, tyrone traveled on his way to work at the rate of 45.36 feet per second.
the coordinates of a' are (-5, 10)
what i did is i turned 2 1/2 into an improper fraction which is 5/2. then i multiplied this (the scale factor) by the coordinates of a which is (-2,4).
hope this : )
