Tom found out that 3 L of fruit punch serves 8 people. He wants to make enough for 48 people. How many liters of punch does he n

yawa3891 [41]

Answer:

Step-by-step explanation:

Use a proportion

$\frac{3}{8}$ = $\frac{x}{48}$

8*6=48

So if we multiply 3*6, we get how many liters it takes to serve 48 people

3*6=18

Determine the equation of a cubic function with zeros at -2, -4, and 3 that passes through the point (4, 144)

levacccp [35]

$\boxed{f(x)=3(x+2)(x+4)(x-3)}$

<h2>Explanation:</h2>

Since the cubic function has zeroes at:

$x=-2 \\ \\ x=-4 \\ \\ x=3$

Then, we can write this function as:

$f(x)=a(x-(-2))(x-(-4))(x-3) \\ \\ f(x)=a(x+2)(x+4)(x-3)$

So our goal is to find the leading coefficient $a$ . Since that cubic function passes through the point (4, 144), then it is true that:

$f(4)=144 \\ \\ \\ So,\ plug \ these \values \ in \ the \ function: \\ \\ f(x)=a(x+2)(x+4)(x-3) \\ \\ 144=a(4+2)(4+4)(4-3) \\ \\ 144=a(6)(8)(1) \\ \\ 144=a(48) \\ \\ a=\frac{144}{48}=3$

Finally, the cubic function is:

$f(x)=3(x+2)(x+4)(x-3)$

The graph is shown below. As you can see the zeroes are:

$(-2,0) \\ \\ (-4,0) \\ \\ (3,0)$

And the function passes through $(4,144)$
