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.

Answer:
Step-by-step explanation:
Distance from earth to moon =238,857 :
x-92350373 = 92589230
x= 238857
Distance from sun to moon. = 92,350,373 miles
Distance from earth to moon=184,939,603 miles
Distance from sun to moon. = 277,528,833 miles
Distance from earth to moon=238,857 miles
Distance from sun to moon. =92,828,087 miles
Answer:
x=3
Step-by-step explanation:
The product of the lengths of the segments of one chord equals the product of the segments of the other.
9*5 = x*5x
45 = 5x^2
Divide each side by 5
45/5 = 5x^2/5
9 = x^2
Take the square root of each side
sqrt(9) = sqrt(x^2)
3 =x
