Write the equation of a graph that models the shock wave (seismic wave) from an earthquake, 20 seconds after the quake. Assume that the wave travels 8km/s.
Interpret the equation.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .

step-by-step explanation:

54/3 is 18 so 18 is your answer
