A ball is dropped from a height if 30 feet the ball bounces after each bounce the height attained by the ball is 60% of the previous height write an nth term formula to model the situation what is the maximum height attained by the ball after five bouncesA.0.12ft
B.6.40ft
C.2.33ft
D.1.40ft

Answers

This information will be modeled using the formula
thus we shall have:
Sn=ar^n
where:
a=first term
r=common ratio
from the information:
a=30 ft
r=60/100=3/5=0.6
therefore the formula will be
Sn=30(0.6)^n
where n is the number of terms:
thus when n=5 th sum will be:
S5=30(0.6)^5
S5=30(0.6)^5
S5=2.33 ft
Answer: 2.33 ft

Answer:

2.33

  • Step-by-step explanation:

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.A(n) = 1 + (n – 1)(–5.7)


1, –21.8, –56


–5.7, –21.8, –51.3


1, –16.1, –50.3


0, –17.1, –51.3


If someone answers this, i'd like if someone could help me to know how to solve it too, please and thank you!

Answers

1, - 16.1, - 50.3 ← third on list

To find the required terms, substitute n = 1, 4, 10 into the rule and evaluate

A(1) = 1 + (1 - 1)(- 5.7) = 1 + 0 = 1

A(4) = 1 + (4 - 1)(- 5.7 ) = 1 + (3 × - 5.7 ) = 1 - 17.1 = - 16.1

A(10) = 1 + (10 - 1 )(- 5.7) = 1 + (9 × - 5.7) = 1 - 51.3 = - 50.3

\bf \stackrel{A(n)=1+(n-1)(-5.7)}{ \begin{array}{ll} n\qquad \qquad &A(n)\n \cline{1-2} 1&1+(1-1)(-5.7)\n &1+0\n &1\n\n 4&1+(4-1)(-5.7)\n &1+(3)(-5.7)\n &1-17.1\n &-16.1\n\n 10&1+(10-1)(-5.7)\n &1+(9)(-5.7)\n &1-51.3\n &-50.3 \end{array} }
