Compute the missing data in the table for the following exponential function f (x) = (one-fourth) Superscript x.

aliina [53]

Answer:

$F(4) = \frac {1}{256}$

Step-by-step explanation:

Given the following mathematical function;

$F(x) = \frac {1}{4^{x}}$

When x = 1

$F(1) = \frac {1}{4^{1}}$

$F(1) = \frac {1}{4}$

When x = 2

$F(2) = \frac {1}{4^{2}}$

$F(2) = \frac {1}{4*4}$

$F(2) = \frac {1}{16}$

When x = 3

$F(3) = \frac {1}{4^{3}}$

$F(3) = \frac {1}{4*4*4}$

When x = 4

$F(4) = \frac {1}{4^{4}}$

$F(4) = \frac {1}{4*4*4*4}$

$F(4) = \frac {1}{256}$

When x = 5

$F(5) = \frac {1}{4^{5}}$

$F(5) = \frac {1}{4*4*4*4*4}$

$F(5) = \frac {1}{1024}$

a number with 2 consecutive natural digits, how many units will it increase if written in reverse order. Detail solution pls

svetlana [45]

Answer:

It will increase by 9 units.

Step-by-step explanation:

We can write the lowest number as 10a + (a + 1) and the highest is the reverse which is 10(a + 1) + a.

Subtracting:

10(a + 1) + a - (10a + a +1)

= 10a + 10 + a - 10a - a - 1

= 10a - 10a + a - a + 10 - 1

= 10 - 1

= 9.
