Would a 51-foot ladder be long enough to climb a 50-foot wall? Sketch a graph and find your answer using a trigonometric ratio.

It is not long enough.

Step-by-step explanation:

Ok, we know that the "rule" for the distance between the base of the ladder and the wall is that, for each 4 ft that the ladder rises, we must have 1 foot between the base of the ladder and the wall.

then, for a 50 feet wall, the ladder must rise 50 ft, this means that the base of the ladder must be:

50ft/4 = 12.5 feet away from the wall.

Now, these two values can be thought as the cathetus of a triangle rectangle, and the ladder will be the hypotenuse, then we have (using Pythagoras theorem)

H = √(12.5ft^2 + 50ft^2) =  51.54 ft

So the theoretical safe value is bigger than the one we have, this means that the 51-foot ladder is not long enough.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
