<h2>Answer:</h2>
is the Square Root Function. These are the characteristics of the graph of the square root function:
- The domain of the function is the set of all non negative real numbers.
- The range of the function is the set of all non negative real numbers.
-
The graph has an intercept at
.
-
The graph is increasing on the interval
.
Since the function , then this stands for the form:
. This form tells us that the graph of f has been shifted c units downward where the value c = 2 in this problem. The graphs of both functions are shown below. The red one is
while the blue one is
Answer:
1. wire is approx. 143.96 ft
2. pole is approx. 106.55 ft
Step-by-step explanation:
Mapping the information on the SOHCAHTOA picture below:
Φ = 46
wire = hypotenuse
adjacent side = 100
CAH is most suitable:
cos 46° = 100/wire => wire = 100/cos 46 ≈ 143.96
pole = opposite side + 3
TOA is most suitable:
tan 46° = (pole-3)/100 => pole = 3 + 100 * tan 46 ≈ 106.55
