Answer:

The corresponding point for the function f(x - 4) is (4 , 1)

Step-by-step explanation:

* <em>Lets explain how to solve the problem</em>

- If the function f(x) translated horizontally to the right by h units, then

the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left by h units, then

the new function g(x) = f(x + h)

- The given function is f(x)

- Point (0 , 1) lies on the graph of f(x)

- We need to find the corresponding point of (0 , 1) for the function

f(x - 4)

- The function f(x - 4) means that f(x) is translated 4 units to the right

∵ x subtract by 4

∴ f(x) translated horizontally four units to the right

- If any point (x , y) translated 4 units to the right, then x-coordinate

of the point will added by 4 to give image (x + 4 , y)

∵ The point is (0 , 1)

∴ Its image is (0 + 4 , 1)

∴ Its image is (4 , 1)

* The corresponding point for the function f(x-4) is (4 , 1)

Four friends are playing a game. They randomly choose a handful of marbles from a bag. The player with the highest ratio of blue

Monica [59]

We are given the number of Blue and Purple Marbles for each of the four friends. So first we have to find the ratio of blue marbles to purple marbles for each of them.

A) Rosa

Number of blue marbles = 10

Number of purple marbles = 12

Ratio of blue to purple marbles = $\frac{10}{12}=0.833$

B) Chi

Number of blue marbles = 5

Number of purple marbles = 6

Ratio of blue to purple marbles = $\frac{5}{6}=0.833$

C) Alberto

Number of blue marbles = 5

Number of purple marbles = 12

Ratio of blue to purple marbles = $\frac{5}{12}=0.417$

D) Pedro

Number of blue marbles = 10

Number of purple marbles = 6

Ratio of blue to purple marbles = $\frac{10}{6}=1.667$

From the above calculations we can see that Pedro has the highest value of ratio for blue marbles to purple marbles. Also we can see Pedro is the only one for whom the number of blue marbles is more than the number of purple marbles. So this confirms that our calculation is correct.

Thus, the player which gets to go first is Pedro.
