Answer:
<em>The ladder needs to be placed at 5 m from the wall.</em>
Step-by-step explanation:
<u>Pythagoras's Theorem</u>
Being a and b the legs of a right triangle and c its hypotenuse, then
The image shows a ladder of length c=13 m as the hypotenuse of the right triangle formed by the height, the ladder, and the ground.
We are given the height up the wall as a=12 m.
We calculate the distance b solving it from the equation above:
Substituting:
Operating:
Taking the square root:
b = 5 m
The ladder needs to be placed at 5 m from the wall.
Answer:
Using the slope formula with points (0,-1) and (-4,4)
Step-by-step explanation:
Step 1: find the points, (0,-1) and (-4,4)
Step 2: Insert plot points into <em>Slope formula: (tip: M means slope)</em>
m(slope)= -> m(slope)=
Step 3: <em>Solve:</em>
m(slope)=
Answer:
Slope is
or m =
OR (if your teacher wants the answer in decimal form rounded to the nearest 10th.) m = -1.3
