Answer:

$F(3)=\frac{1}{64}$

B is correct option.

Step-by-step explanation:

The given function is $F(x)=(\frac{1}{4})^x$

To find the value of F(3), we substitute x = 3 in the given function

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

We can rewrite this as

$F(3)=\frac{1\times1\times1}{4\times4\times4}$

On simplification, we get

$F(3)=\frac{1}{64}$

Hence, B is correct option.

12% of 80 working out

horsena [70]

How to do the problem:
Assuming that you mean you want 12% of the number 80 and showing work, here is the answer:

To get X percent of any number, write the percent as a decimal and then multiply that decimal by the whole.

What I mean:

You want 12% of 80
so first change 12% into a decimal
12% is equal to .12 as a decimal

Then multiply that decimal by the whole
Since you want 12% of 80, 80 is the whole

that means you do .12 * 80
which is equal to 9.6
Thus(answer)
12% of 80 = 9.6
