Answer: Correct answer is C -I just took the test

we have the function f(x) = 4(1/2)x, and we want to reflex it over the x-axis.

you can see in the graph that the reflex over this axis changes the sign of f(x) in all the points (where f(0) = 4, g(0) = -4, f(1) = 2, g(1) = -2, and so on), then the reflex, g(x) is equal to -f(x)

now we have:

g(x) = -f(x) = - 4(1/2)x

then the right answer is the third option:

g(x) = -4(1/2)x

Charlie has a piece of toast that has cream cheese on one side, and he dropped it once. One time, it landed with the cream chees

Leya [2.2K]

Answer:

Probability of landing cream cheese side up 3 times is tex]\frac{1}{4}[/tex]

Step-by-step explanation:

The probability of getting cheese side up is one half ( $\frac{1}{2}$ .

And this probability does not depend on the result of the last time you dropped it or the result before that.

So every time you drop a piece of toast the probability of getting cheese side up is one half ( $\frac{1}{2}$ .

Charlie has already dropped it once (1st time) and it landed on cream cheese side up. So probability for this is 1 because it has already happened.

Next time (2nd time) he drops, the probability of landing cream cheese side up is $\frac{1}{2}$

When he drops the piece of toast again (3rd time) the probability of landing cheese side up is again $\frac{1}{2}$ .

So the probability of landing cream cheese side up 3 times is,

$1*\frac{1}{2} *\frac{1}{2}$

= $\frac{1}{4}$

Maurinko [17]

We know, Volume of rectangular prism = l * b * h
If all dimensions are doubled, then it would be: 2 * 2 * 2 * v
V' = 8V

In Short, Volume will increase to it's 8 times
