Because, you can’t take the popcorn and turn it into kernels again.

When popcorn<span> is popped, liquid inside the kernel is changed to steam. Pressure from the steam builds up inside the kernel. When the pressure reached a critical stage the kernel pops turning itself inside out. This is a PHYSICAL </span>CHANGE<span>.</span>

Gala2k [10]

Answer:

a) 2x^4 + 8x^3 + x^2 + 3x

b) evaluate this polynomial at x = 10

Step-by-step explanation:

Hi!

a)

The product of a sum is the sum of the products, having said this:

(2x^3 + 8x^2 + x + 3) \times x = 2x^4 + 8x^3 + x^2 + 3x

b)

We can use the result from part a and consider x = 10.

First lets take the first polynomial

2x^3 + 8x^2 + x + 3 = 2(10)^3 + 8 (10)^2+10^1+3(10)^0

Knowing that every number (excepting probably 0, which could be undefined for some or 1 for others) to the power of 0 is one:

2x^3 + 8x^2 + x + 3 = 2(1000)+ 8(100)+10+3(1) = 2813

Which is the initial number

Now lets conisder the product of the polynomial times x and evaluate it at x=10:

(2x^3 + 8x^2 + x + 3) \times x = 2x^4 + 8x^3 + x^2 + 3x

(2(10)^4 + 8(10)^3 + 10^2 + 3(10) = 2 (10000) + 8(1000) + 100 + 3(10)

= 28130

We can now see that teh rule is treu because we can see the whole number as a sum of numbers from 0 to 9 multiplied by a power of 10, and when it is multiplied by 10, each power increases by one, and at the end, the final result is adding a zero at the end
