Answer:
40.3 feet
Step-by-step explanation:
Use trigonometry.
First, set your calculator to Degrees instead of Radians. Next, draw a model like the attached image to help you better understand the question.
Now, figure out which trigonometric ratio to use. In this case, it is easiest to use sine (or cosine).
sin(38°) = x / 125
125(sin(38°)) = x
x ≈ 37.046
Finally, to find the height, simply add how high the hand is from the ground:
h = 37.046 + 3.25 = 40.296
So,
h ≈ 40.3 ft
Answer:
The real solutions of f(x)=0 are: 0, 2, 5, 6
Step-by-step explanation:
We are given:
The graph of y = f(x)
We need to find all of the real solutions of f(x) = 0?
By looking at the graph we need to find the values of y when x =0
Looking at the graph, when x=0 we get
0, 2,5 and 6
So, the real solutions of f(x)=0 are: 0, 2, 5, 6
I am attaching the figure, that determines the answers.
