5 is not a function because if you draw a vertical line then it touches twice which is not a function

6 is a function

7 is not a function because there are 2 of the same inputs

8 is a function because it passes the vertical line test

9 is not a function

10 is a function

Hopefully that helped!

Does 10p/2q = 5p/q<br> I think it is not equal but it doesn't seem right.
Rufina [12.5K]

Answer: \frac{10p}{2q}=\frac{5p}{q}  (TRUE)

Step-by-step explanation:

For this exercise it is important to remember that, by definition, fractions have the following form:

\frac{a}{b}

Where "a" is the numerator and "b" is the denominator.

The numerator and the denominator are Integers, but the denominator cannot be zero (b\neq 0)

In this case you have the following equation provided in the exercise:

\frac{10p}{2q}=\frac{5p}{q}

To find out if the left side of the equation is equal to the right side, it is necessary to simplify the fraction on the left.

Notice that the numerator and the denominator of the fraction on the left  can be both divided by 2. Then, you can simplify it.

So, you get;

\frac{5p}{q}=\frac{5p}{q}\ (TRUE)

(with steps please) Find the inverse Laplace transform, f(t), of the function: 16/(s-4)^3
Stells [14]

Answer:  The required inverse transform of the given function is

f(t)=8t^2e^{4t}.

Step-by-step explanation:  We are given to find the inverse Laplace transform, f(t), of the following function :

F(s)=\dfrac{16}{(s-4)^3}.

We have the following Laplace formula :

L\{t^ne^{at}\}=\dfrac{n!}{(s-a)^{n+1}}\\\\\\\Rightarrow L^{-1}\{\dfrac{1}{(s-a)^{n+1}}\}=\dfrac{t^ne^{at}}{n!}.

Therefore, we get

f(t)\\\\=L^{-1}\{\dfrac{16}{(s-4)^3}\}\\\\\\=16\times\dfrac{t^{3-1e^{4t}}}{(3-1)!}\\\\\\=\dfrac{16}{2}t^2e^{4t}\\\\\\=8t^2e^{4t}.

Thus, the required inverse transform of the given function is

f(t)=8t^2e^{4t}.

A 12 ounce can of store brand tomato paste costs $1.46 at a supermarket. The unit price of the sauce is listed on the shelf belo
kykrilka [37]
You can calculate it by divided but most of the people get confused about is it gonna be 12/1.46 or 1.46/12. The correct is 1.46/12 because take the money divided all 12 to get a unit price if you take 12/1.46 which mean divided all ounce can to money and that makes nonsense.


So 1.46/12 = $0.12 for each ounce can

Hope this help!
