Answer:

Relation

Explanation:

The definition of a relation is just a set of ordered pairs.

A function is a relation in which each domain element is paired with exactly one range element.

It can't be a function because if it is a vertical line, then the x-value is the same for the whole line.

A circle is graphed with its center on the origin.The area of the circle is 49 square units.What are the coordinates of the x-in

neonofarm [45]

Answer:

3.95 and -3.95

Step-by-step explanation:

To graph a circle you can use the formula or (x – h)^2 + (y – k)^2 = r^2. So substituting in the given, we get x^2+y^2=49/pi. The x intercept is when y=0. So x^2=49/pi and so

x = sqrt(49/pi) and rounding to the nearest tenth, we get 3.95 and -3.95 because it isn’t a principal square root.

Patrick is keeping track of how far he jogs each morning.

katrin2010 [14]

Answer:

21:50

Step-by-step explanation:

We need to find the ratio of 420 m to 1 km.

We know that,

1 km = 1000 m

So,

The ratio becomes,

$\dfrac{420\ m}{1\ km}=\dfrac{420\ m}{1000\ m}\\\\=\dfrac{42\ m}{100\ m}\\\\=\dfrac{21}{50}$

So, the required ratio is 21:50.

A softball fits snuggly inside a cubical box that is 4 inches on each side. What is the volume of the softball that fits snuggly

Natali5045456 [20]

Answer:

33.5 cubic inches.

Step-by-step explanation:

If the softball fits perfectly inside the cubical box, the softball is a sphere with diameter of 4 inches (radius os 2 inches).

The volume of a sphere is given by:

$V= \frac{4}{3}\pi r^3$

For r = 2 inches:

$V= \frac{4}{3}*3.14* 2^3\\V=33.5\ in^3$

The volume of the softball is 33.5 cubic inches.
