Answer:
C. quadratic
Step-by-step explanation:
You can rightly guess that ballistic motion is described by a <em>quadratic</em> function.
Differences of the y-values are 5.75, 3.25, 0.75, -1.75, -4.25.
First differences are not constant, but form a linear sequence that decreases by 2.5 between each pair. Since second differences are constant, the function is described by a 2nd-degree polynomial function, a <em>quadratic</em>.

<em>Comment on other function types</em>
Linear functions have constant first differences. Exponential functions have exponentially increasing first differences. Logarithmic functions have first differences that increase by smaller and smaller amounts.
It's a straight line at -5
100 I guess because if 16*10 is 160 then 10*10 is 100
Answer:
y=1/3x+2
Step-by-step explanation:
The value of arccos(-√3/2) is 5π/6.
In the given question,
We have to find the value of
.
The given term is
.
We using the quadrant rule.
The value is in negative so we check in which quadrant the value of cos negative.
As we now that in second quadrant only the value of sine and cosine is positive and all value are negative.
The second quadrant of 180 degree or we can also write 180 degree as π.
From the trigonometry table we know that at 30 degree or (π/6) the value of cos is √3/2.
So the value of cos at which -√3/2 is
-√3/2 = cos(π - π/6)
-√3/2 = cos(π×6/6 - π/6)
-√3/2 = cos(6π/6 - π/6)
-√3/2 = cos{(6π- π)/6}
-√3/2 = cos 5π/6
So we can write it as
arccos(-√3/2)=arccos(cos 5π/6)
Since there is a arccos and cos both so only left 5π/6.
arccos(-√3/2)=5π/6
Hence, the value of arccos(-√3/2) is 5π/6.
