Answer:

PEMDAS” (parenthesis, exponents, multiplication, division, addition, subtraction) to help you remember? Memorable acronyms aren't the only way to memorize concepts.

Step-by-step explanation: -> 3 x 2 +( 4 - 1) = ??

always when you see these in your equation you always start with these>>>(4-1=3) then 3x2=6 then you add that then you get 9

9 is your answer hope this helps

Answer:

The answer is 9.

Step-by-step explanation:

PEDMAS stands for :

$\purple\star$ P = Parentheses
$\purple\star$ E = Exponents
$\purple\star$ M = Multiplication
$\purple\star$ D = Division
$\purple\star$ A = Addition
$\purple\star$ S = Subtraction

To solve the given equation we will follow the PEDMAS rule.

$\begin{gathered}\qquad{\twoheadrightarrow{\sf{3 \times 2 + (4 - 1)}}} \\ \\ \qquad{\twoheadrightarrow{\sf{3 \times 2 + (3)}}} \\ \\ \qquad{\twoheadrightarrow{\sf{3 \times 2 + 3}}} \\ \\ \qquad{\twoheadrightarrow{\sf{6+ 3}}} \\ \\ \qquad{\twoheadrightarrow{\sf{9}}} \\ \\ \qquad{\star\underline{\boxed{\tt \pink{ \: 9 \: }}}}\end{gathered}$

Hence, the answer is 9.

A) what is average rate of change of f(x) over the interval from x=5 to x=9? (table shows values of f(x). graph shows function o

SVETLANKA909090 [29]

Answer:

See below for answers and explanations

Step-by-step explanation:

Part A

The average rate of change of a function over the interval $[a,b]$ is equal to $\frac{f(b)-f(a)}{b-a}$ , hence:

$\frac{f(b)-f(a)}{b-a}\\\\\frac{f(9)-f(5)}{9-5}\\\\\frac{14-(-4)}{9-5}\\ \\\frac{14+4}{4}\\ \\\frac{18}{4}\\ \\\frac{9}{2}$

Therefore, the average rate of change of $f(x)$ over the interval $[5,9]$ is $\frac{9}{2}$ .

Part B

Do the same thing as in Part A:

$\frac{f(b)-f(a)}{b-a}\\ \\\frac{f(1)-f(0.25)}{1-0.25}\\ \\\frac{2-5}{0.75}\\ \\\frac{-3}{0.75}\\ \\-4$

Therefore, the average rate of change of $g(x)$ over the interval $[0.25,1]$ is $-4$ .

Part C

To interpret our answer from Part B in terms of the real world it represents, we say that between 0.25 seconds and 1 second, the ball falls at a rate of 4 feet per second (since our average rate of change is negative).
