Hello,

Question:

Jack popped some popcorn, but 3 of the 150 kernels did not pop.

Determine which popcorn snacks below has the same ratio of unpopped to total kernels as Jack's popcorn.

We Know:

3 out of 150 did not pop

Solution:

3/150 = 3 to 150

Find ratios similar to this one,

4/200

2/100

1/50

So now we know for every kernel that dosent pop there are 50 that did.

Answers:

4 unpopped out of 200 kernels

1 unpopped out of 50 kernels

Sketch the graph of the function f(x) = -(x-4)^3 by indicating how a more basic function has been shifted, reflected, stretched,
irina [24]

Step-by-step explanation:

In the attached images we can see the rigid transformation of the function f(x) =x^{3}

1. The basic graph f(x) =x^{3}

2. The reflected graph f(x) = -x^{3}

3. The displaced graph f(x) = -(x-4)^{3}

Reflection: In the expression f(x) = -(x-4)^{3} , the sign - before the parenthesis indicates that the function is reflected in the x axis, for this case the function is even, this means that -f(x) = f(-x) , then the reflection on the x axis is equal to the reflection on the y axis.

Displacement: We observe the term (x-4) of the function f(x) = -(x-4)^{3} and analyze the value -4, where, the sign - indicates displacement to the right and the value 4 indicates the amount that the graph shifted .
