Answer:

  A: geometric; 4 times

  B: arithmetic: 4 more

Step-by-step explanation:

An arithmetic model is a linear model, where the rate of change is constant.  Growth or decay is by a constant amount from one interval to the next.

A geometric model is an exponential model, in which the rate of change is proportional to the amount. Growth or decay is by a constant factor from one interval to the next.

__

<h3>A)</h3>

The equation for the sequence is given in "explicit" form:

  A_n=2^{2n}

The exponent can be split so this can be rewritten as ...

  A_n=(2^2)^n=4^n

If this were written in recursive form, it would look like ...

  A_0=1,\ A_n=4\times A_{n-1}

The fact that terms are related by a constant factor tells you the model is geometric. The factor tells you each hour the population is 4 times what it was in the previous hour.

__

<h3>B)</h3>

The given equation is in "recursive" form. It tells you each term is 4 more than the previous one. This constant difference between terms means the model is arithmetic.

_____

<em>Additional comment</em>

In general, words like "more" or "increase" refer to addition, and the words "times" or "factor" refer to multiplication.

Divided 85 lbs 2 oz by 6? PLEASE HELP its 12:00 am and I can't think right now
Ostrovityanka [42]
1 pound = 16 ounces
So we have 85 lbs and 2 oz, that is if we convert them to ounces:
85(16) + 2 = 1362 oz
so we have 1362 oz total due to the conversion factor stated above, now we only need to divide:
1362/6 = 227
that is 227 oz
or if we want the result in pounds (lbs), we can by dividing again by 16
227/16 = 14.19 lbs
