Answer:42.98
Step-by-step explanation:
Hf=√(11^2-8^2)
Hf=√(121-64)
Hf=√(57)
Hf=7.5
11/sin90 =7.5/sinG
Sin90=1
11/1=7.5/sinG
Cross multiply
11 x sinG=7.5 x 1
11sinG=7.5
Divide both sides by 11
11sinG/11=7.5/11
sinG=0.6818
G=sin(inverse)(0.6818)
G=42.98
Answer:
B., E.
Step-by-step explanation:
what was the difficulty ? this is just to understand the movement of a thrown rock.
what happens, when you throw a rock through the air ? it will first move up a little bit, reaches a maximum height, and then drops down again.
that is what the graphic shows.
so, can A. be correct ? no. as we move from 0 seconds to the right (time passes) the height of the rock increases first (before decreasing again later on).
can C. be correct ? no, it would mean that the function would look the same on both sides of the x-axis. this is clearly impossible.
can D. be correct ? no, nowhere in the graph is the height (= the functional value, the y to the x) negative.
can F. be correct ? no, we clearly see the maximum height at 1.5 seconds. at 3 seconds the height is actually at its minimum.
Answer:
<h2>30.4</h2>
Step-by-step explanation:
sin x = 4.6/9.1
sin x = 0.5055
Thus , x = 30.4
