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.

Steps to solving equations:
Simplify/combine the like terms
Isolate the variable (Get the variable on one side
Solve for the variable

-2y - 7 + 5y = 13 - 2y Simplify/Combine terms
3y -7 = 13 - 2y Isolate variable by adding 2y to both sides
5y - 7 = 13 Add 7 to both sides to get y alone on one side
5y = 20 Divide by 5 on both sides to solve for y
y = 4
You can check your answer by replacing y with 4 in the original equation.

The temperature rose by 11 degrees Fahrenheit today. Write a signed number to represent this temperature change
Anestetic [448]
The rise in temperature by 11 degrees Fahrenheit can be represented by the temperature change, ΔT = +11 °F. The temperature change is positive because the temperature increased as stated in the question. Moreover, the formula for temperature change is: ΔT = T_final - T_initial. This means that for this case, the final temperature is higher than the initial temperature.

We solve 6 + 4

6 + 4 = 10.

Square root of 10:

\boldsymbol { \sqrt{6 + 4} =  \sqrt{10}  }\\&#10;\\&#10;\\&#10;\boldsymbol {  \sqrt{10}l\underline{ \ 3.16227766017}}\\&#10;\boldsymbol {  \underline{- 10}l \ 3.16227766017 \times 3.16227766017 }\\&#10;\boldsymbol { \ \ \ 00}

<span>The square root of 10 is a periodic decimal (decimal that has infinite decimals, worth the redundancy)

 What is that periodic decimal?
</span>
\boxed{\textbf{3.16227766017} \boldsymbol{ \ \Leftarrow }\textbf{Square root of 10}}
