Was dis a question or an answer, dawg??
Answer:
7/8
Step-by-step explanation:
0.875 = 875/1000
875/1000 Divide numerator and denominator by 125
7/8
The formula for the circumference of a circle:
C = 2(π)(r)
To solve for r, just divide both sides by 2π.
C/2π = r
For this problem, you are given the C, so plug that into the equation.
8π = 2(π)(r)
Now to solve for r, just divide both sides by 2π
4 = r
The radius of the circle is 4.
Solving the quadratic function, it is found that the particle returns to the ground after 7 seconds.
<h3>What is the quadratic function for the particle's height?</h3>
The particle's height after t seconds is modeled by the following equation:
s(t) = -16t² + v(0)t.
In which v(0) is the initial velocity of the particle, which in this problem is of 112 ft/s, hence:
s(t) = -16t² + 112t.
The particle hits the ground when s(t) = 0, hence:
s(t) = 0
-16t² + 112t = 0
-16t(t - 7) = 0.
Hence the non-trivial solution is:
t - 7 = 0 -> t = 7.
The particle returns to the ground after 7 seconds.
