Total number of seats = 5
Total number of friends = 5

We want to find in how many ways the 5 friends can sit or be arranged in 5 seats. This can be found using permutations.So we are to find the permutations of 5 objects taken 5 at a time. This can be expressed as 5P5.

5P5 = 120

So, the 5 friends can sit in 120 different ways.

The correct answer is option D

miss Akunina [59]

20100 = 16000 * (1.02)^ t

20100/16000 = 1.02^t

1.25625 = 1.02^t

log 1.25625 = t * log 1.02

t = log 1.25625 / log 1.02
= 11.5

ricardo's rose bush was 9/12 yard tall, he pruned the rose bush by cutting off 1/9 yard. Ricardo measured the rose bush today, a

Arisa [49]

Answer:

The length of the Ricardo's rose bush is 1.47 yards .

Step-by-step explanation:

The initial height of the rose bush = 9/12 yard = 0.75 yards

The length of the bush which is cut = 1/9 yard

So, the remaining height = The initial height - The pruned part

= $\frac{9}{12} - \frac{1}{9} = \frac{3(9)- 4}{36} = \frac{23}{36}$

So, the pruned part of the tree = 23/36 yards in height

Now, the growth of the bush after some time = 5/6 yards

So, the present height of the bush

= Height after it was pruned + The growth

= $\frac{23}{36} + \frac{5}{6} = \frac{23 + 6(5)}{36} = \frac{23 + 30}{36} = \frac{53}{36}$

Hence, the length of the Ricardo's rose bush is 53/36( = 1.47) yards .

1) So writing in terms of x, we have: y=30,000-2000x or f(x) = -2000x +30,000

Hence, the y intercept is the point 30,000 ( 0, 30000) and the slope is -2000 for it is a decreasing function.
