R(x) is a polynomial. Thus, the domain is the same as the range.

Domain = range = ALL REAL NUMBERS.

We can also express the answer as

The equation for the circle below is x ^2 + y^2 = 100. what is the length of the circles radius?

Ganezh [65]

Answer: 10 units.

Step-by-step explanation:

The equation of the circle in Center-radius form is:

$(x - h)^2 + (y - k)^2 = r^2$

Where the center is (h,k) and "r" is the radius.

The equation of the circle given is:

$x ^2 + y^2 = 100$

You can observe that is written in Center-radius form.

Then, you can identify that:

$r^2=100$

Knowing this, you need to solve for "r" to find the lenght of the radius.

This is:

$r=\sqrt{100}\\\\r=10$

Therefore, the lenght of the radius is 10 units.

F(1)=−2<br> f(2)=5<br> f(n)=f(n−2)⋅f(n−1)<br> f(3) = ?

3241004551 [841]

<h3>Answer: -10</h3>

Work Shown:

f(n) = f(n-2)*f(n-1)

f(3) = f(3-2)*f(3-1)

f(3) = f(1)*f(2)

f(3) = -2*5

f(3) = -10

at the county fair , 12% of the pepole who attended received free water bottels . if 1,500 people receive dfree water bottles ,

sweet-ann [11.9K]

12500 people went to fair

<h3><u>Solution:</u></h3>

Given that at the county fair , 12% of the people who attended received free water bottles

1,500 people received free water bottles

To find: number of peoples went to fair

Let "a" be the number of peoples went to fair

From given information,

12% of the people who attended received free water bottles and 1,500 people received free water bottles

Which means 12% of total people is equal to 1500

12% of total people = 1500

12 % of "a" = 1500

$\frac{12}{100} \times a = 1500\\\\a = 1500 \times \frac{100}{12}\\\\a = \frac{150000}{12} = 12500$

Thus 12500 people went to fair
