third option is the correct answer....
Sixty eight and nine plus eleven equals 12
<span>let:
X = the distance of the bottom of the ladder from the wall at any time
dX/dt = rate of travel of the bottom of the ladder = 1.1 ft/sec
A = the angle of the ladder with the ground at anytime
dA/dt = rate of change of the angle in radians per second
X = 10 cos A
dX/dt= -10 sin A dA/dt = 1.1
dA/dt = -1.1/(10 sinA)
When X = 6; cosA = 6/10; sinA = 8/10
Therefore:
dA/dt = -1.1/(10 x 0.8) = -0.1375 radiant per second. </span>
Answer:
Elliot is able to move the table through, since 2 3/4 is more than 2 5/8.
Step-by-step explanation:
2 3/4 - 2 5/8 = 0.125
0.125 is a positive number.
So, Elliot is able to move the table through the doorway.
