Fill in the blank with the recursive function. Be sure to include the starting point.

erik [133]

Answer:

The recursive function that represents the number of books Ashley has at any time is

$a_n=a_{n-1}-n$

starting at

$a_1=100$

Step-by-step explanation:

Ashley has 100 books that she wants to give away at the rate of n books per week.

So,

$a_1=100\\ \\a_2=100-n=a_1-n\\ \\a_3=a_2-n\\ \\...\\ \\a_n=a_{n-1}-n$

Thus, the recursive function that represents the number of books Ashley has at any time is

$a_n=a_{n-1}-n$

starting at

$a_1=100$

Find the number of positive integers less than 100,000 whose digits are among 1, 2, 3, and 4. Hint consider the

Verdich [7]

Answer:

1364 is the number of possibilities for positive integers less than 1,00,000.

Step-by-step explanation:

1. 5 digit numbers:

We have 5 places here, and each place can have 4 options because repetition is allowed.

So, total number of possibilities for 5 digit numbers:

$4 \times 4 \times 4 \times 4 \times 4\\ \Rightarrow 1024$

2. 4 digit numbers:

We have 4 places here, and each place can have 4 options because repetition is allowed.

So, total number of possibilities for 4 digit numbers:

$4 \times 4 \times 4 \times 4 \\ \Rightarrow 256$

3. 3 digit numbers:

We have 3 places here, and each place can have 4 options because repetition is allowed.

So, total number of possibilities for 3 digit numbers:

$4 \times 4 \times 4 \\ \Rightarrow 64$

4. 2 digit numbers:

We have 2 places here, and each place can have 4 options because repetition is allowed.

So, total number of possibilities for 2 digit numbers:

$4 \times 4 \\ \Rightarrow 16$

5. 1 digit numbers:

We have 1 place here, and each place can have 4 options because repetition is allowed.

So, total number of possibilities for 1 digit numbers:

$4$

We can add all the above possibilities to find the total.

So, number of positive integers less than 100,000 whose digits are among 1, 2, 3, and 4 = 1024 + 256 + 64 + 16 + 4 = 1364

How much ₹ each will get if 242.46₹ is distributed equally among the students

slavikrds [6]

Complete Question:

How much ₹ will each get if 242.46₹ is distributed equally among the 6 students

Answer:

Each of the 6 students will get ₹40.41

Step-by-step explanation:

Given

$Amount = 242.46$

$Students = 6$

Required

Determine how much each student gets

To do this, we simply divide the total amount by the number of students

i.e.

$Each\ Students = \frac{Amount}{Number\ Students}$

$Each\ Students = \frac{242.46}{6}$

$Each\ Student = 40.41$

Hence, each of the 6 students will get ₹40.41

Answer:

Answer is in the pic

Step-by-step explanation:

A translation is just a movement of the figure so in this case you just add 3 to the x part of the coordinate.

so originally k (-2,5) m (-3,1) l (1,1)

add 3 to x so

k (1,5) m (0,1) l (4,1)
