Answer:

x + 3 + \frac{13}{x-3}

Step-by-step explanation:

Divide using Synthetic division

dividing by ( x - 3)

Using 0 to represent the x- term

3 |  1  0   4

     ↓ 3    9

        +     +

   ------------------

     1   3    13 ← remainder

Thus

\frac{x^2+4}{x-3} = x + 3 + \frac{13}{x-3}

The half life of a certain substance is about 4 hours. The graph shows the decay of a 50 gram sample of the substance that is me
olga55 [171]
I can't see how any of those formulas show exponential decay.  (Did you type those correctly?)

The formula that will show the remaining amount correctly is:
ending amount = Bgng Amount / 2^n
where "n" is the number of haf-lives.

So, for example if half life = 4 hours and if we want to calculate the amount after 9 hours (that's 2.25 half-lives) then:
ending amount = Bgng Amount / 2^n
ending amount = 50 / (2^(9/4))
ending amount = 50 / 2^2.25
ending amount = 50 / <span><span><span>4.75682846 </span>
</span></span><span><span>ending amount = </span> 10.5112 grams
</span>Looking at the graph, we see that's about right.

Factor the expression below.<br> 16x^2-49
zysi [14]

Answer:

(4x + 7) (4x - 7)

Step-by-step explanation:

16x^2 will be broken down to 4x and 4x since when you multiply them, it will equal 16x^2

Then -49 can be broken down to 7 & -7 since 7 x (-7) = -49
