Let f(x)=3x+1 and g(x)=x^2+xAfter simplifying (fg)(x)

natima [27]

$(fg)(x)\text{ = }3x^3+4x^2+x$

Here, we want to find the product of the two given functions

Mathematically;

$\begin{gathered} (fg)(x)\text{ = f(x) }\times\text{ g(x)} \\ \\ =(3x+1)(x^2+x) \\ =3x^3+3x^2+x^2+x \\ =3x^3+4x^2+x \end{gathered}$

What is the domain and range of the problem? How many beats will she have in half an hour? Is the graph discrete or continuous?

san4es73 [151]

From the statement, we know that Miss Butterkey's heart rate is 80 beats per minute.

So the ratio of beats per minute is:

$r=80\cdot\frac{\text{beats}}{\min }\text{.}$

The number of beats as a function of time is given by the product:

$b(M)=r\cdot M\min =80\cdot\frac{beats}{\min}\cdot M\cdot\min =80M\cdot\text{beats.}$

Where t is the time in minutes.

(0) If we define:

• M = # of minutes,

• b = # of beats after M minutes.

Using the equation of b(t), we have:

$b=80M\text{ beats }\Rightarrow M(b)=\frac{b}{80}\text{.}$

(1) Domain and range

If we consider the independent variable as the number of minutes M, the domain is:

$\text{Domain = 0, 1, 2, 3, }\ldots\text{.}$

If we consider the dependent variable as the number of beats b, the range is:

$\text{Range = }0,80,160,240,\ldots\text{.}$

(2) # of beats after half an hour

After half an hour the time is t = 30 min. Replacing this value in the equation of b(t), we get:

$b(30\min )=80\cdot\frac{beats}{\min}\cdot30\cdot\min =2400\text{ beats.}$

(3) The graph of heartbeats as a function of the minutes is discrete. That's because we can only have an integer number of beats.

(4) Labels of the graph

• horizontal label: number of minutes M,

• vertical label: number of beats b.

(5) Graph

Answers

• (0), M(b) = b/80

• (1) ,Domain = 0, 1, 2, 3, ... , Range = 0, 80, 160, 240, ...

• (2), b(30 min) = 2400 beats

• (3), The graph is discrete.

• (4) ,Horizontal label: # of minutes M, Vertical label: # of beats

• (5), Graph

One-third of a number yields twelve. Which equation could be used to find the number?

LenaWriter [7]

Answer:

1/3n=12

Step-by-step explanation:

The reason why it is 1/3n=12, is because you know that the number in front of n is 1/3. By figuring that out, you have already ruled out 3n=12 and 3n=-12. Finally, you know that 12 is a positive number leaving you with 1/3n=12.

What is 40+56 in GCF

KengaRu [80]

The GCF stands for greatest common factor. To represent a sum by its GCF we need to use the distributive property and we need to first find the GCF of the numbers. Let's break each number by its factors:

$\begin{gathered} 40=2\cdot2\cdot2\cdot5 \\ 56=2\cdot2\cdot2\cdot7 \end{gathered}$

We now multiply the numbers that appear on both.

$\text{GCF}=2\cdot2\cdot2=8$

We now apply the distributive property:

$8\cdot(5+7)$
