Given the endpoint (-9,3) and (1,8) partition the segment into the ratio 2:3<br>​
Sindrei [870]

Answer:

P = (-5,5)

Step-by-step explanation:

Let the segments be A and B

A = (-9,3)

B = (1,8)

m:n = 2:3

Required

Determine the endpoints after it is divided into ratios.

<em>Let the point be represented with P</em>

The formula to use is:

P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})

Where

A = (-9,3)  ----- (x_1,y_1)

B = (1,8) ------ (x_2,y_2)

So:

P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})

P = (\frac{2 * 1 + 3 * -9}{2 + 3},\frac{2 * 8 + 3 * 3}{2 + 3})

P = (\frac{-25}{5},\frac{25}{5})

P = (-5,5)

A ladder is leaning against a building so that the distance from the ground to the top of the ladder is 22 feetfeet less than th
ivann1987 [24]
So basically the ladder is creating a right triangle with the ground and the wall. Ladder is the hypotenuse (h), building = b, ground = g
b = h - 22 ft
g = 1010 ft
use Pythagorean Theorem to determine the length of h:
{c}^{2}  =  {a}^{2}  + {b}^{2}  \\  {h}^{2}  =  {(h - 22)}^{2}  + {1010}^{2}  \\ {h}^{2}  =  {h}^{2} - 44h + 484 + 1020100
The h^2 terms cancel out to = 0
0 = - 44h + 484 + 1020100 \\ 44h = 1020584 \\ 44h \div 44 = 1020584 \div 44 \\ h = 23195.1 \: feet
