127. Ladder stability: From past mishaps, Seth knows his
trasher [3.6K]

Answer:

h = 7.63 ft

Step-by-step explanation:

When a ladder leans against a wall, it forms a right angled triangle. The length of the ladder becomes the hypotenuse of the triangle, while the distance of the bottom of ladder from the wall and the height of top of the ladder from the ground becomes the perpendicular and base, depending upon the selected angle. Using Pythagora's Theorem in this right angled triangle:

Hypotenuse² = Perpendicular² + Base²

where,

Hypotenuse = Length of Ladder = 16 ft

Base = Distance between bottom of ladder and wall = x

Perpendicular = Height of top of of the ladder from ground = x + 6 ft

Therefore,

(16)² = x² + (x + 6)²

256 = x² + x² + 12x + 36

128 = x² + 6x + 18

x² + 6x - 110 = 0

solving the quadratic equation and using positive value:

x = 1.63 ft

So, the height of top of ladder is:

h = 1.63 ft + 6 ft

<u>h = 7.63 ft</u>

This exercise uses, the population growth model
timofeeve [1]

P is equal to 8700% for population x time in hours.

<h3>What is population growth model?</h3>

P is equal to 8700% for population x time in hours. 2Ae%5E%28kx%29

K's model must be solved. ln%28p%29=ln%288700%29%

2Bkx%2Aln%28e%

29\skx%

2A1=ln%28p%29-ln%288700%

29\sk=%281%

2Fx%29%

28ln%28p%29-ln%288700%29%29

Replace the point (1,10000).

k=%281%

2F1%29%

28ln%2810000%

29-ln%288700%

29%

29\sk=ln%2810000%

29-ln%288700%

29 k=0.13926, which you might only desire to three or maybe even two significant figures.

You may just enter 10000% if you want p after two hours.

And it SHOULD be the same as 8700% (2810000%2F8700%).

Just give it a shot and see, 2Ae%5E%280.139%2A2%29. More particular, the model is highlighted by p=8700%. 2Ae%5E%280.139% 2Ax%29% 29.

Determine how long to double x.

Take the logs on both sides, then find x.

To put it more simply, start with this form: 2=1%2Ae%5E%280.13926%2Ax%29
