1) A ball is dropped from a height of 50 feet. How long after it is dropped will it reach a height of 18 feet?

Nookie1986 [14]

Answer: 1.41 seconds

Step-by-step explanation:

The problem gives the initial velocity by saying "dropped." This indicates a velocity of zero. Acceleration can also be found because the object is in free fall. It would experience the acceleration of gravity. We can use the kinematic equation:

$(y_f-y_i)=V_it+\frac{1}{2}at^2$

The velocity term completely cancels because the object was dropped with an initial velocity of 0.

$(18-50)=\frac{1}{2} (32.17)t^2\\$

$-32=-16.085t^2\\t=\sqrt{1.989} =1.41s$

Write a rule for the nth term of the geometric sequence for which a1=−6 and a5=−486

patriot [66]

The geometric rule for the nth term of the geometric sequence for which a1 =−6 and a5=−486 is -6 × 3^(n - 1)

<h3>The nth term of a geometric sequence</h3>

First term, a1 = -6

Fifth term, a5 = -486

a5 = ar^(n - 1)

-486 = -6 × r^(5-1)

-486 = -6r⁴

r⁴ = -486 / 6

r⁴ = 81

r = 4√81

r = 3

Geometric rule:

nth term = ar^(n-1)

nth term = -6 × 3^(n - 1)
