Step-by-step explanation: To find the volume of a sphere, start with the formula for the volume of a sphere which is shown below.
Here, we are given that our sphere has a radius of 4 units.
So plugging into the formula, we have 
.
Start by simplifying the exponent.
(4 units)³ is equal to (4 units) (4 units) (4 units) or 64 units³.
So we have 
.
Next, we multiply (4/3)(64) which can
be thought of as (4/3)(64/1)
So multiplying across the numerators and across the denominators,
we have 
.
Begin by finding the lowest point the quadratic equation can be, the vertex;
x²-1= is just a translation down of the graph x²
vertex; (0, -1) and since the graph of x² would extend to infinity beyond that point, we can say {x| x≥0} for domain and {y| y≥-1}.
For the linear equation, it is possible to have all x and y values, therefore range and domain belong to all real numbers.

Answer:
the third one
Step-by-step explanation:
y+8= 4(x-3)
y+8= 4x-12
y= 4x-20
Answer:
The simple interest is $300.
Step-by-step explanation:
<em>Find the Interest amount.</em>
I: Interest ?
P: Principle Amount $2500
R: Rate 6% = .06
T: Time Period (in years) 2 Years
<em>Convert into equation to find Simple Interest</em>
I = Prt
I = (2500)(.06)(2)
<em>Calculate</em>
I = 300
