Answer:

Let's say that

f

)

=

x

−

10

The graph below shows

y

=

f

(

x

)

:

graph{x^2-10 [-6, 6, -15, 15]}

When we want

f

(

x

)

>

0

, we want

y

>

0

, or all the values of

x

where

f

Divide. 6 ÷ 1/4<br>helpp​
artcher [175]

Answer:

24

Step-by-step explanation:

Let’s write them as numbers

6/1/4

Dividing by 4 means multiplying by its reciprocal.

Reciprocal of a number: Can be found when you switch the positions of the denominator and numerator

So reciprocal of 1/4=4/1=4

Next, we multiply by its reciprocal

6*4=24

Therefore, 6 divided by one fourth is 24.

Why was it helpful in the paper ball situation helpful in the paper ball situation to rewrite the expression to determine specif
Contact [7]

Answer:

Step-by-step explanation:

I'm not sure I know what the paper ball situation is, but I can tell you that especially when working with a set formula in physics, math or chemistry (I'd include biology if I knew any biology) that it is a good idea to write down your givens.

The equation you are given is going to fall apart once you know what your givens are and what they do.

I just looked up the Paper Ball Situation. This is a wonderful piece of physics. It immediately opened up all sorts of treasures once they experimenters thought of using tin foil. Givens are a necessity in such an experiment.

Cubed root x cubed root x2​
Yuki888 [10]

Answer:

Final answer is \sqrt[3]{x^1}\cdot\sqrt[3]{x^2}=x.

Step-by-step explanation:

Given problem is \sqrt[3]{x}\cdot\sqrt[3]{x^2}.

Now we need to simplify this problem.

\sqrt[3]{x}\cdot\sqrt[3]{x^2}

\sqrt[3]{x^1}\cdot\sqrt[3]{x^2}

Apply formula

\sqrt[n]{x^p}\cdot\sqrt[n]{x^q}=\sqrt[n]{x^{p+q}}

so we get:

\sqrt[3]{x^1}\cdot\sqrt[3]{x^2}=\sqrt[3]{x^{1+2}}

\sqrt[3]{x^1}\cdot\sqrt[3]{x^2}=\sqrt[3]{x^{3}}

\sqrt[3]{x^1}\cdot\sqrt[3]{x^2}=x

Hence final answer is \sqrt[3]{x^1}\cdot\sqrt[3]{x^2}=x.
