6 0

Answer:

360

Step-by-step explanation:

Given

Digits: 0 to 5

Required

Number of 4 digit passcode that can be generated.

First, we need to get the number of usable digits.

Digits 0 to 5 = 0,1,2,3,4,5

Number of digits = 6

To make a 4 digit passcode;

The first digit can be taken from any of 6 digits

The second digit, any of the remaining 5 digits

The third digit, any of the remaining 4 digits

The fourth digit, any of the remaining 3 digits

Number of passcode = 6 * 5 * 4 * 3

Number of passcode = 360

Answer:

OPTION C: The ratio is a constant.

OPTION E: The ratio is equal to b.

Step-by-step explanation:

Given: $f(x) = a.b^x$

The ratio of f(x + 1) and f(x) = $\frac{f(x + 1)}{f(x)} = \frac{a.b^{x + 1}}{a.b^x}$

Since, $a^{x + 1} = a^x. a$

$\implies \frac{f(x + 1)}{f(x)} = \frac{a.b^x.b}{a.b^x}$

Cancelling out $a.b^x$ we get:

$\frac{f(x + 1)}{f(x)} = b$

This shows that the ratio is always a constant and that constant is equal to b.

Sherry had an ending balance f 125.36, outstanding deposits of 153.53, and utstanding checks of $100.19. What was her checkbook

DENIUS [597]

Answer:

The checkbook balance is $178 .7.

Step-by-step explanation:

As given

Sherry had an ending balance $ 125.36, outstanding deposits of $153.53, and outstanding checks of $100.19.

Thus

Checkbook balance = Ending balance + Outstanding deposits - Outstanding checks

Putting the values in the above

Checkbook balance = $ 125.36 + $153.53 - $100.19

= $ 278.89 - $100.19

= $ 178.7

Therefore the checkbook balance is $178 .7.
