A ladder 50 dm long when set against the wall of a house just reaches a window at a height of 48 dm. How far is the lower end of
1 answer:
Answer:
14dm
Step-by-step explanation:
To solve this question we can use the Pythogorean theorem
a^2 + b^2 = c^2
In this case, The ladder is the hypotenuse, the height is one of the leg of the right angle triangle
Let's keep the missing side as x
If we apply the theorem,
x^2 + 48^2 = 50^2
x^2 + 2304 = 2500
x^2 = 2500 - 2304
x^2 = 196

The 400th term is 425.
There are floor(√400) = 20 squares in the range 1..400, so the 400th term will be at least 420. There are floor(∛420) = 7 cubes in the range 1..400, so the 400th term may be as high as 427. However, there are![\lfloor\sqrt[6]{427}\rfloor=2](https://tex.z-dn.net/?f=%5Clfloor%5Csqrt%5B6%5D%7B427%7D%5Crfloor%3D2)
numbers that are both squares and cubes. Consequently, the 400th term will be 427-2 = 425.
