what- a ladder rests against a building at an angle as shown, with endpoints (-2,0 ) and (0,8). what is the slope of the ladder?

A ladder of length 5m rests against a wall The foot of the ladder is 1.7m from the base of the wall How far up the wall does the ladder reach?
6.7
A ladder long rests against a vertical wall If the top of the ladder slides down at a rate of how fast is the bottom of the ladder sliding away when the bottom of the ladder is away from the wall?
If h is vertical height, b=horizontal distance from wall to bottom of ladder and l=lenght of ladder,we can say lsquared = hsquared + b squared. Now differentiate w.r.t. time t. 2l*dl/dt= 2h* dh/dt + 2b*db/dt =0 However this solution doesn't give exactly the same answer when one solves the problem geometrically or using simple pythagorus. For example ,if l=20m and b=12 m and h=16m and db/dt is 2m/s, I calculate dh/dt as !.5 m/s using calculus but 1.717 m/s using geometry or straight Pythagorus. Where is the fallasy inthe method using calculus? Ray Bevan
9.0 m ladder rests against the side of a wall the bottom of the ladder is 1.5 m from thebase wall derter the measure of the angle between the ladder and the ground to the nearest degree?
Oh honey, we've got ourselves a classic right triangle situation here. Using some good ol' trigonometry, you can find that the angle between the ladder and the ground is approximately 83 degrees. Just remember, math may not be your friend, but it's definitely not your enemy either.
Where can you purchase foot rests from?
Foot rests can be bought in a variety of places. One can buy them at furniture stores, home improvement stores, and home supply stores. One may also find foot rests through online retailers.

The foot of a ladder is placed 5 feet from a building the top of the ladder rests 12 feet up on the building how long is the ladder?
13 feet
A ladder rests against a wall the top of the ladder reaches 15 feet up the wall and makes an angle of 53 with the wall how long is the ladder?
If the wall is straight and the ground level then this is an outline of a right angle-triangle. If the top of the ladder makes an angle of 530 with the wall then the bottom of the ladder must make 370 to the ground. Use the sine ratio to find the length of the ladder (which will be the hypotenuse) sin = opp/hyp rearranged to hyp = opp/sin hyp = 15/sin370 = 24.92460212 feet So the length of the ladder is 25 feet correct to the nearest foot.
The foot of a ladder is placed 6 feet from a wall If the top of the ladder rests 8 feet up on the wall. how long is the ladder?
62+82=36+64=100 and the squared route of 100 is 10

Is ladder a type of third class lever?
Yes, a ladder is a type of third-class lever, where the effort (force applied by the person climbing) is between the fulcrum (the point where the ladder rests on the ground) and the load (the weight of the person).
What is the answer to A 15-m long ladder rests against a wall at an angle of 60 degrees with the ground How far is the foot of the ladder from the wall?
15*cos(60) = 7.5 7.5 m
9.0 m ladder rests against the side of a wall the bottom of the ladder is 1.5 m from thebase wall derter the measure of the angle between the ladder and the ground to the nearest degree?

What is the bottom of an object called?
The bottom of an object is called the base.
What is the analogy for bottom?
The answer is foundation because it means the natural or prepared ground or base on which some structure rests.
What is point of the elbow that rests on the table?
The point of the elbow that rests on the table is generally called the olecranon process. It helps provide support when leaning on the table. Over time, prolonged pressure on the olecranon can cause discomfort or irritation, so it's important to adjust position to avoid strain.
