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

Lin’s family has completed 40% of a trip. They have traveled 80 miles. How far is the trip?

Elena L [17]

Answer:

200 miles

Step-by-step explanation:

80 = 40% of the trip

Divide 40% and 80 by 10

40% / 10 = 4

80 / 10 = 8

8 = 4% of the trip

100 / 4 = 25

8 x 25 = 200

The trip is 200 miles.

Express the function F in the form f ∘ g. (Enter your answers as a comma-separated list. Use non-identity functions for f(x) and

damaskus [11]

Answer:

$F(x) = f \circ g$

$f(x) = x + 2$ and $g(x) = x$

Step-by-step explanation:

Given

$F(x) = x + 2$

Required

Express as

$F(x) = f \circ g(x)$

In functions:

$f \circ\ g(x) = f(g(x))$

So, we have:

$f(g(x)) = x + 2$

g(x) can be set to x and f(x) to x + 2

Hence:

$F(x) = f \circ g$

When: $f(x) = x + 2$ and $g(x) = x$
