29. repetition of digits is permitted and the letters must be 2 DIFFERENT vowels (a, e, i, o, u).

vova2212 [387]

Answer:

c) 20,000

Step-by-step explanation:

Number of digits = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 = 10,

Number of vowel letters = a, e, i, o, u = 5

Repetition of digits is permitted but repetition of vowel letters is not permitted

Let the password be presented in dash form as shown below:

____ ____ ____ ____ ____ =

D D D V V

where:

D = possible number of digits to fill the spot

V = possible number of vowels to fill the spot

Since repetition of digits is permitted, each spot marked as D can be filled with any one of 10 digits from 0 - 9

The first spot marked V has 5 possible options (a, e, i, o, u) & the second spot marked V only has 4 possible options (since repetition of vowels is not permitted).

We then place the number of possibilities in each spot and multiply them to determine the number of passwords possible

10 * 10 * 10 * 5 * 4 = 20,000

Therefore, the number of possible passwords is 20,000

If 7a+20b=28-b,what is the value of a in terms of b?

shusha [124]

7a+20b = 28-b
7a = 28-b-20b
7a = 28-21b
a= 28/7 - 21/7 b = 4-3b

You were given the polynomial f(x)=3x^3+13x^2+19x+k and you know that f(-2)=0find k

eduard

Answer:

k = 10

Explanation:

The initial polynomial is:

$f(x)=3x^3+13x^2+19x+k$

If f(-2) = 0, then when we replace x by -2, the result will be 0. It means that we can write the following equation:

$\begin{gathered} f(-2)=3(-2)^3+13(-2)^2+19(-2)+k=0 \\ 3(-2)^3+13(-2)^2+19(-2)+k=0 \end{gathered}$

Therefore, we can solve for k as follows:

$\begin{gathered} 3(-8)+13(4)+19(-2)+k=0 \\ -24+52-38+k=0 \\ -10+k=0 \\ -10+k+10=0+10 \\ k=10 \end{gathered}$

So, the value of k is 10

A sequence is defined resursively by the formula f(n + 1) = f(n) + 3. The first term of the sequence is -4. What is the next ter

Vlad1618 [11]

The next term of the sequence is -1.

Given, a sequence is defined recursively by the formula

f(n + 1) = f(n) + 3.

The first term of the sequence is -4.

We, have to find the next term of the sequence,

On using the formula of the sequence, we get

f(n + 1) = f(n) + 3

As, f(1) = -4

Put n = 1,

f(1 + 1) = f(1) + 3

f(2) = f(1) + 3

f(2) = -4 + 3

f(2) = -1

So, the next term of the sequence is -1.

Hence, the next term of the sequence is -1.
