Answer:
sin(x) =
x = 16.26°
Step-by-step explanation:
First use Pythagorean theorem to find the length of the hypotenuse. Use . Since we know a and b we can plug in to find c. When we plug in we get:
. When we solve this out we get 25 = c.
Now that we know the value of c, we also know sin(x) = . Using this we see that sin(x) =
.
To get the exact degree value of x, take the inverse sin of :
which gives us 16.26020° rounded to 16.26°
Answer:
Step-by-step explanation:
We have the quadratic function:
And we want to determine its axis of symmetry.
Notice that this is in vertex form:
Where (<em>h, k</em>) is the vertex of the parabola.
From our function, we can see that <em>h</em> = 4 and <em>k</em> = -2.5. Hence, our vertex is the point (4, -2.5).
The axis of symmetry is equivalent to the <em>x-</em>coordinate of the vertex.
The <em>x-</em>coordinate of the vertex is 4.
Therefore, the axis of symmetry is <em>x</em> = 4.
