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

Write the expression as a single natural logarithm.3 ln x – 5 ln c

shtirl [24]

The rules are ...
$\Longrightarrow \ln(\frac{a}{b})=\ln(a)-\ln(b)$
$\Longrightarrow \ln(a^{b})=b\ln(a)$

Your expression makes use of both these rules.
$3\ln(x)-5\ln(c)=\ln(x^{3})-\ln(c^{5})=\ln \left( \dfrac{x^{3}}{c^{5}} \right)$

Your single logarithm is ...
$\ln \left( \dfrac{x^{3}}{c^{5}} \right)$

TRANSPORTATION The cost of riding in a cab is $3.00 plus $0.75 per mile. The equation that represents this relation is y=0.75x+3

Amanda [17]

Answer:

f(17) = $15.75

The amount it takes for a trip of 17 miles is $15.75

Step-by-step explanation:

Here, we want to calculate f(17)

The equation is given as;

y = 0.75x + 3

For f(17), substitute x for 17

y = 0.75(17) + 3

y = 12.75 + 3

y = $15.75

What f(17) means is that the ride was for 17 miles

$15.75 is for a trip of 17 miles
