It depends upon whose foot it is.........

$$\\0.0081^{3/4}\\\\
=(0.0081^{1/4})^3\\\\
=0.3^3\\\\
=0.027$$

check

$${{\mathtt{0.008\: \!1}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{4}}}}\right)} = {\frac{{\mathtt{27}}}{{\mathtt{1\,000}}}} = {\mathtt{0.027}}$$

24 days......the LCM of 6 and 8........

$${\sqrt{{\mathtt{69}}}} = {\mathtt{8.306\: \!623\: \!862\: \!918\: \!074\: \!9}}$$

3x+4 = 4x+2       |   - 3x

     4 =  x + 2       |   -2

     2 = x                          =>    x = 2

Find f(-5) if f(x) = |x + 1|

l -5 + 1  l   =   l -4 l  = 4

Find f(-11/5) if f(n) = 5n + 6

5(-11/5) + 6   =  (-11) + 6 =  - 5

Select the points that lie on the function h(x) = 3x ²......(1,3) and (-1, 3)

If f(x) is a function and f(1) = 5, then which of the following could not be true?

f(1) = 1......we can't have a single x value associated with two different y values.......this violates the "vertical line test"

That was a great answer anon :)

Yeah, He broke It Down. It's 8.

Find x if f(x) = 2x + 7 and f(x) = -1

OK.......just set  2x + 7  = -1

Subtract 7 from both sides   

2x  = -8        divide by 2 on both sides

x = -4

--------------------------------------------------------------------------------------------------------------------------

Find f(-7) if f(x) = 2x + 8

Just put -7 into f(x) and evaluate....so we have   ...  2(-7) + 8  =  -14 + 8 = -6

-------------------------------------------------------------------------------------------------------------------------

f(-1)   means that we want to stick -1 into x - 5...so we have  -1 - 5 = -6

The rest are done similarly......

Find x if f(x) = 2x + 7 and f(x) = -1.

$$\\ f(x) = 2x+7 \qquad | \qquad f(x) = \textcolor[rgb]{1,0,0}{-1} \\\\
\textcolor[rgb]{1,0,0}{-1} = 2x+7\\\\
2x = -8\\\\
x=-4$$

Find f(-7) if f(x) = 2x + 8.

$$\\ f(x) = 2x+8 \qquad | \qquad x = \textcolor[rgb]{1,0,0}{-7} \\\\
f(\textcolor[rgb]{1,0,0}{-7}) = 2\cdot (\textcolor[rgb]{1,0,0}{-7}) + 8\\\\
f(\textcolor[rgb]{1,0,0}{-7}) = -14+ 8\\\\
f(\textcolor[rgb]{1,0,0}{-7}) = -6$$

If f(x) = x - 5, then match each of the following.

f(-1) = -1 - 5 = -6

f(0) = 0 - 5 = -5

f(1) = 1 - 5 = -4

f(2) = 2 - 5 = -3

f(5) = 5 - 5 = 0

f(8) = 8 - 5 = 3

8 is the answer

512 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2
Grouped appropriately, that's (2 * 2 * 2) * (2 * 2 * 2) * (2 * 2 * 2)

So the cube root of 512 = 2 * 2 * 2 = 8

Hope that helps.

 ok so the answer is 8.3

8.30662386292

8 something.

Thank you so much i now understand it

The */ symbols together mean nothing so this cannot be calculated

Wow, You're Very Smart. I hate to ask so many questions about functions, But I'm A Freshman And I Still Don't Know Them. I Feel Stupid. Thank You Though.

I agree that the chance of getting all those letters in that order from any given starting point is 1/28^18   

I agree with how many letters are typed in a year.     

But after that you lost me.     

There is probably some key thing that I am supposed to understand but I do not understand.

In reality, the monkey could get that combination on the first go - it is afterall just as likely as any other set of 18 characters.  

OR

The monkey could type away for any finite period and the sentence will not appear.

I am sure that someone could work out the probability of it a appearing in any given period of time but I do no see how they could specify exactly how long it would take.

Like I said, I expect I am missing some key understanding of what is being asked here.  

You're A Saint! Thank You. :)

Find g(1) if g(x) = x ² + 1.

$$\\ g(x) = x^2+1 \qquad | \qquad x = \textcolor[rgb]{1,0,0}{1} \\\\
g(\textcolor[rgb]{1,0,0}{1}) = \textcolor[rgb]{1,0,0}{1}^2 + 1\\\\
g(\textcolor[rgb]{1,0,0}{1}) = 2$$

The problem is "Find f(2) if f(x) = (x + 1)²

$$\\ f(x) = (x + 1)^2 \qquad | \qquad x = \textcolor[rgb]{1,0,0}{2} \\\\
f(\textcolor[rgb]{1,0,0}{2}) = (\textcolor[rgb]{1,0,0}{2} + 1)^2\\\\
f(\textcolor[rgb]{1,0,0}{2}) = 3^2\\\\
f(\textcolor[rgb]{1,0,0}{2}) = 9$$
