Answer:
Step-by-step explanation:
We can do this  a couple of ways. We can graph it -- see below. Or we can do the math.
Math
y = x^2 - 2x - 15 
This trinomial factors into
y = (x - 5)(x + 3)
from which 
x - 5= 0
x = 5
and
x + 3 = 0
x = - 3
The y intercept is the value obtained when all the xs on the right = 0
y = 0^2 - 2*0 - 15
y = - 15
<em>Answer</em>
- x intercepts: (-3,0),(5,0)
- y intercept: (0,-15)
The graph is below.
 
        
             
        
        
        
APR is different than other compounding periods because you would need to find some equivelancy to compare things at.
        
             
        
        
        
the formula for volume of sphere is 4/3||r^3 
diameter=2radius
in the formula we need to have radius but we have been given diameter so we convert diameter to radius
d=2r
r=d/2
