Juanita, who is 1.82 meters tall, wants to find the height of a tree in her backyard. From the tree's base, she walks
12.20 meters along the tree's shadow to a position where
the end of her shadow exactly overlaps the end of the tree's
shadow. She is now 6.10 meters from the end of the shadows.
How tall is the tree?

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
