Painters use ladders to paint on high buildings and often use the help of Pythagoras' theorem to complete their work. The painter needs to determine how tall a ladder needs to be in order to safely place the ladder away from the wall, so it won't tip over. In this case the ladder itself will be the hypotenuse. A painter who has to paint a wall which is 12 meters high is going to put the base of the ladder 5 meters away from the wall to ensure it won't tip. What will be the length of the ladder required by the painter to complete his work?

sine

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

believe it or not anna is correct good job anna give me a fist bump there u go gal
