Answer: Choice A, -1540 feet
----------------------------------
Explanation:
Multiply the rate (44 ft per sec) by the number of seconds (35) to get 44*35 = 1540
The answer will be negative to indicate that the altitude has gone down. If you put in a positive change, then the altitude would go up. So that's why the answer is choice A
Note: when you multiply 44 ft/sec by 35 sec, the "second" units cancel out leaving just feet.
Another note: if you want, think of the 44 as -44 to indicate that the plane is decreasing at a rate of 44 ft/sec
6^3 (or 6 to the 3rd power) is 216. The volume is 216 inches.
Solving for x?? x=0, -2, 2
2.50 meters because it is what it is
XZ=XY+YZ
JL=JK+KL
use the trigonometric values table or unit circle to calculate the expression
