Eddi Din [679]

We will have the following:

*It will have a domain of x equal or greater than 0:

x\ge0

It will have a domain of y equal or greater than 0:

y\ge0

***

We have the following:

We determine the domain as follows:

Since the function is subject to a root, no negative value can be put in it, so its domain (Since x is not accompanied by any value in the root) can only "hold" values equal or greater than 0.

We determine the range as follows:

Since the function is subject to a root, it's solutions will never be negative, so its range can only hold values equal or greater than 0.

e-lub [12.9K]

Answer:

<u>25%</u> is the percent error.

Step-by-step explanation:

Given:

The world's largest marathon, The New York City Marathon, is held on the first Sunday in November each year. Between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.

Now, to find the percent error.

As given, between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.

<em>The actual measure</em> = 2 million.

The estimated measure = 2.5 million.

<em>So, the error</em> = 2.5-2=0.5\ million.

Now, to get the percent error:

\frac{0.5}{2} \times 100.

=0.25\times 100

=25\%.

Therefore, 25% is the percent error.

Help me solve this please!
sergiy2304 [10]

Answer: -1, 0, 1, 2, 3

Step-by-step explanation:

If we say the expression out loud, we say it as "m is greater than -2 but less than or equal to 3."

This is because < or > means less than or greater than. These don't include the given value.

≤ or ≥ means less than or equal to or greater than or equal to. These do include the given value/values.

In this equation, we don't include -2, but we include 3. That's why the included values are -1, 0, 1, 2, 3.
