Step-by-step explanation:
that means we divide 2/3 by 4.
2/3 / 4 = 2/3 / 4/1 = 2/3 × 1/4 = 2/12 = 1/6
so each quarter of the remaining 2/3 pizza is actually 1/6 of the complete pizza.
Substitute x with -12
1/3(9+(-12) = 1/3(-3)
the answer is -1
Answer:
Y=5/2x-3
Step-by-step explanation:
The equation's slope is -4/10, which simplifies to -2/5. The reciprical of this, 5/2, is the slope of a perpendicular line. The first possibility you commented is the only one to have this slope.
X^2+(y-2)^2=4 is a circle centered at (0,2) with radius 2.
Thus, when you rotate it around the y-axis (around x=0),
you get a sphere with radius 2.
((which is centered at (x,y,z)=(0,2,0), if you take y to be
the vertical axis ... not that you need to know this for volume))
--------------------------------------------------------------
Volume of a sphere formula: V = (4/3)πr^3.
