A sequence is defined recursively using the formula f(n + 1) = -0.5f(n). If the first term of the sequence is 120, what is f(5)?
PolarNik [594]

Answer: 7.5

Step-by-step explanation:

The given formula tells us that the next term f(n+1) of the sequence is -0.5 times the previous term f(n)

First term of the sequence is f(1) = 120

Second term of the sequence is f(2) = f(1+1) = -0.5 f(1) = -0.5 (120) = -60

Third term of the sequence is f(3) = f(2+1) = -0.5 f(2) = -0.5 (-60) = 30

Fourth term of the sequence is f(4) = f(3+1) = -0.5 f(3) = -0.5 (30) = -15

Fifth term of the sequence is f(5) = f(4+1) = -0.5 f(4) = -0.5 (-15) = <em>7.5</em>

Clare is paid $90 for 5 hours of work. At this rate, how many seconds does it take for her to earn 25 cent?
Alla [95]
50 secs

as $90÷5hrs= 18 $ per hrs

$18÷60min=$0.30 per min

$0.30÷60sec=$0.005 per sec

$0.25÷$0.005= 50sec to make $0.25

so 50sec is the answer

Can someone answer this question please answer it correctly if it’s corect I will mark you brainliest
umka21 [38]

Answer:

2/9

12.5%, 30% ,45%

Step-by-step explanation:

Possible outcomes

W = wild

S = sandy shores

G = green hills

W6  W7   W10

S6  S7   S10

G6  G7   G10

There are 9 outcomes

2 are over a week without hills  (W10 and S10) and

P(10 days not at hills) = # more than 7 days no hills/total

                                               =2/9

We need all the numbers in the same form, I will change to decimal

1/8 = .125

30% = .30

.45

Smallest to largest

.125 <.30 <.45

1/8 < 30% < .45

Changing to percent form

12.5%, 30% ,45%
