How does the graph of y=\sqrt(x+2) compare to the graph of the parent square root function?
Fofino [41]

Answer:

The graph is a horizontal shift of the function two units to the left.

Step-by-step explanation:

The graph is a horizontal shift of the function two units to the left.

Remember that horizontal shifts appear as additions of a constant "c" to the x-coordinate inside the function. When the constant is negative the shift is to the right in |c| units, and when the constant is positive (like in this case) the shift is to the left in |c| units.

If a person stands 40 ft from a tree and the angle of elevation made from their eyes (5 ft above the ground) to the top of the t
goldenfox [79]

Using the given information, the height of the tree is 48 ft

<h3>Trigonometry </h3>

From the question, we are to determine the height of the tree

In the given diagram, the height of the tree is (x + 5) feet

First, we will determine the value of x

tan 47° = x / 40

x = 40 × tan47°

x = 42.89 ft

∴ The height of the tree = (42.89 + 5) ft

Height of the tree = 47.89 ft

Height of the tree ≈ 48 ft

Hence, the height of the tree is 48 ft.
