Can foot drop be treated?

Foot drop is a medical disorder that is considered to be a gait abnormality. In order for it to be treated, the underlying order that is causing it must be found and corrected.


What is the formula area of a parollelogram?

Same as for a rectangle: base x height. However, the height must be measured perpendicular to the base.


Which letter continues this pattern of letters in the alphabet b e i n?

it takes 2 letters to reach b, then 3 to reach e, 4 to i, 5 to n, which means the next letter must be 6 away. The letter is therefore T


Why is a foot a measure of distance?

It probably has something to do with the relatively simplistic and probable use in early times before measurement standardization of using ones foot to provide a estimate of length. When standardization became widespread (based on the theory presented above) the inches in a foot must have been decided to be 12 inches, which is relatively close to the average American shoe size of 10.5


What is answer of antilog of -4.1?

Both for logs and antilogs, the base must be specified. Once you decide on your base, you can calculate that on any scientific calculator. Use the antilog function (base 10, or base e, if that's what you need), or calculate 10 to the power -4.1 (if you want a base-10 antilog), or e to the power -4.1 (if you want a base-e antilog), or some other base to this power. In Excel, you can use the power operator. For example, for 10 to the power -4.1 (that is, the antilog, base 10), type the following in an Excel cell: =10^-4.1

How many feet from the base must a 39-foot ladder be placed so that the top of the ladder will reach a point on the house 36 feet from the ground?

Well, using a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse, you need to square 39 and 36. Then your equation should look like a^2 +1296 = 1521, then solve for a^2, getting the variable by itself, so you have a^2 = 225. Then take the square root of both sides leaving you with a= 15. So, the ladder must be placed 15 feet from the base of the house.

How long must a ladder be to reach the top of a 20' wall if the ladder and the wall form a 32 degree angle (at the angle)?

Then an angle of 58 degrees will be at the bottom of the ladder. Use trigonometry and the sine ratio: sin = opp/hyp and hyp = opp/sin hyp = 20/sin(58) = 23.58356807 length of ladder = 24 feet to the nearest foot

Can a roofer who wants to repair your roof that is 28 feet above the ground level use a 28 foot ladder?

No. since the ladder must be on an angle it must have room so that the length of the ladder is equal to the 282 + (distance between bottom of ladder and house)2.

How long must a ladder be to reach to top of a 20 foot wall if the ladder and the top wall form a 32 degree angle at the top in a plus?

The ladder forms the hypotenuse (r) and the wall forms the vertical (y) of a right triangle. sin theta = y / r the angle at the bottom is (90 - 32) = 58 sin 58 = 20 / r r = 20 / sin 58 = 23.583568067241928552025478405751 feet ladder must be about (rounding) 23.6 feet long.
