Answer:
1766.3
Step-by-step explanation:
V=4
/3πr^3
= 4/3(3.14)(7.5)^3
= 4/3(3.14)(421.88)
= 4/3(1324.69)
= 1766.25
= 1766.3

Answer:
The coterminal angles are : 270° , -450°
sketched angle is in third quadrant 
Step-by-step explanation:
The sketch of the angle in standard position is attached  below 
The coterminal angles : 
- 90 + 360 = 270°
-90 - 360 = -450°
Quadrant of the angle( -90° )  = Third quadrant

Hi there! 
In order to factor, start by knowing the variables for each term in the equation ax^2+bx+c
A=1
B=-5
C=4
(Based on the given equation) 
In order to factor, we need to find two numbers that add to the b term (-5) but multiply to the c term (4)
-4*-1=4 
-4+-1=-5
Therefore, the factored form would be y=(x-4)(x-1)
Hope this helps!
