A 4 kg bird is flying and it has a total kinetic energy of 32 Joules. What is the bird's current velocity?

Answers

Answer 1

Answer:

Answer:

K=32J

Explanation:

Kinetic energy is given by:

K=12mv2

We are given that m=4kg and v=4ms.

⇒K=12(4kg)(4ms)2

=32Nm

=32J

Step-by-step explanation:

i have no idea if this helps or not

Dimetri says that a function that is made of terms where the variable is raised only to an odd power will be an odd function. Do you agree with Dimetri? Explain why or why not.

Answers

No, I do not.

Explanation:
Algebraically, an odd function is one where f(-x) = -f(x). This means that if we substitute -x for every x in the function, it should be the same as switching every sign in the function. This does not always work.

For example, if f(x)=x³+7:
f(-x)=(-x)³+7=-x³+7.

However, since the 7 did not become -7, it is not the same as -f(x), so it is not an odd function.

Dimetri statement is incorrect, as the function is odd if its greatest degree is odd when the lower terms are ignored.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

As we know,

For even function: f(-x) = f(x)

For odd function: f(-x) = -f(x)

If Dimetri says that, a function that is made of terms where the variable is raised only to an odd power will be an odd function.

The Dimetri statement is incorrect, as the function is odd if its greatest degree is odd when the lower terms are ignored.

Thus, Dimetri statement is incorrect, as the function is odd if its greatest degree is odd when the lower terms are ignored.

You fill a container 3/4 full of water. The amount of water now in the container is 6 quarts. How much can the container hold?a. 12 qt
b. 8 qt
c. 6 qt
d. 14 qt

Answers

To solve this, you need to use cross multiplication. The first fraction, is 3/4 and the second is 6/x, with x meaning how much the container can hold. Multiply 3x(x) and 4x6 equating to 3x=24. From here, use algebra to solve for x, by dividing both sides by three.
Your final answer will be B) 8 qts

Answer:

8 qt

Step-by-step explanation:

Multiply 3x(x) and 4x6 equating to 3x=24 and then algebra to solve for x, by dividing both sides by three.
