A ladder 10 ft long rests against a vertical wall. If the bottom of the ladder slides away from the wall at a rate of 1.1 ft/s,

pishuonlain [190]

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.

Someone help me determine whether the statement is true or false

enyata [817]

Answer:

The Statement D⊆B is False.

Step-by-step explanation:

Given:

A = {1, 3, 5, 7 }

B = {5, 6, 7, 8}

C = {5, 8}

D = {2, 5, 8}

U = {1, 2, 3, 4, 5, 6, 7, 8}

To Check:

D⊆B = True or False

Solution:

The sign '⊆' symbolize SUBSET

So D⊆B means D is the Sub Set of B

That means All the element of Set D must be there in the SET of B Then it comes True.

Or else it is False

D = {2, 5, 8}

B = {5, 6, 7, 8}

Therefore D⊆B is a FALSE statement

For it to be TRUE we must have set B as

D = {2, 5, 8}

B = {2,5, 6, 7, 8}

Now D⊆B is a TRUE statement
