Answer:
28.2941 feet
Step-by-step explanation:
First we need to imagine a triangle with Justin and his shadow, and the tree and its shadow (as shown in the figure attached)., and then calculate the relation between Justin's height and his shadow's height
The relation between the opposite cathetus (height of Justin) and the adjacent cathetus (height of the shadow) is the tangent of the angle, so:
tan(angle) = 74/102 = 0.7255
The tree and its shadow will have this same angle and therefore this same relation, so:
0.7255 = tree / 39
tree = 0.7255 * 39 = 28.2941 feet
Answer: 5/3
Step-by-step explanation: Parallel lines have the same slope.
So, a parallel slope would be 5/3
Hope this helped!
Every ordered pair has a second number of -6, so the mapping with -6 as the sole number on the right is the appropriate mapping. A mapping is only <em>not a function</em> if it maps a number to two or more different values (as shown in the top diagram of your attachment).
The appropriate choice is not shown in your question. It would be the one attached below.

Step-by-step explanation:
Reflection over x = -1 performs the transformation ...
(x, y) ⇒ (-2-x, y)
The answer is 7(x-1) in factored GCF form
