Answer:

- 3i + 4j

Step-by-step explanation:

A unit vector in the x- direction is represented by i

A unit vector in the y- direction is represented by j

Hence (- 3, 4) = - 3i + 4j

Recursive definitions for subsets of binary strings.Give a recursive definition for the specified subset of the binary strings.

dmitriy555 [2]

Answer:

Step-by-step explanation:

A binary string with 2n+1 number of zeros, then you can get a binary string with 2n(+1)+1 = 2n+3 number of zeros either by adding 2 zeros or 2 1's at any of the available 2n+2 positions. Way of making each of these two choices are (2n+2)22. So, basically if b2n+12n+1 is the number of binary string with 2n+1 zeros then your

b2n+32n+3 = 2 (2n+2)22 b2n+12n+1

your second case is basically the fact that if you have string of length n ending with zero than you can the string of length n+1 ending with zero by:

1. Either placing a 1 in available n places (because you can't place it at the end)

2. or by placing a zero in available n+1 places.

a total eclipse in 2003 lasted 2 17/24,minutes in 2005 it lasted 3/8 of a minute how much longer did it last in 2003

Doss [256]

Answer:

Total eclipse was $2\frac{1}{3}$ minutes longer than in 2005.

Step-by-step explanation:

It is given in the question that total eclipse in 2003 lasted $2\frac{17}{24}$ minutes and in 2005 it lasted 3/8 of a minute.

We have to calculate how much longer did it last in 2003.

So we have to subtract the duration in 2003 by duration in 2005

Total time taken in 2003- total time taken in 2005

$=2\frac{17}{24}-\frac{3}{8}$

$\frac{48+17}{24}-\frac{3}{8}$

$=\frac{65}{24}-\frac{3}{8}$

$=\frac{65-9}{24}$

$=\frac{56}{24}$

$\frac{7}{3}$

$=2\frac{1}{3}$ minutes

If the flotation costs are 2 percent of gross proceeds, and gross proceeds are $250,000, what is the dollar amount of flotation

alina1380 [7]

The dollar amount of the flotation costs by percent of gross proceeds is $5,000

We need to know about the percent theory first, percent is per 100. So when A is 1% of B it means that

A = 1/100 x B

From the question, we know that

The gross proceeds is given by = $250,000 and

the flotation cost is given by = 2% of gross proceeds.

We can write the flotation cost as

Flotation cost = 2/100 x $250,000

Flotation cost = 2/100 x $250,000

Flotation cost = $5,000

Hence, the dollar amount of the flotation costs is $5,000
