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.

The table below lists the masses and volumes of several pieces of the same type of metal. There is a proportional relationship b
castortr0y [4]
 
<span>∵ There is a proportional relationship between the mass and the volume of the places of metal.
Let volume = v and mass = m
So, the relation between volume and mass will take the form:
        v = km
where k is constant and can be calculated as follow:
when m = </span><span>34.932 , and v = 4.1   ⇒⇒⇒ k = v/m = 0.117371
</span>when m = 47.712<span> , and v = 5.6   ⇒⇒⇒ k = v/m = </span>0.117371
when m = 61.344 , and v = 7.2   ⇒⇒⇒ k = v/m = <span>0.117371
when m = </span>99.684 , and v = 11.7  ⇒⇒⇒ k = v/m = <span>0.117371

∴ v = 0.117371 m
</span>
For  v =<span>15.3
∴ m = v/k = 15.3/0.117371 = 130.356 </span><span>gram

</span>The mass of a piece of this metal that has a volume of 15.3 cubic centimeters ≈ 130.4 gram (<span>round to the nearest tenth</span>)
