Answer:
3/4
Step-by-step explanation:
2/5+1/4+1/10=8/20+5/20+2/20=（8+5+2）/20=15/20=3/4
Answer:
the slope of y=3x/7+4/7 is M=3 over 7
Answer:
x=-27
Step-by-step explanation:
-0.57x+0.27x = 8.1
-0.3x = 8.1
x = -8.1/0.3
x = -27
Using the shell method, the volume is
Each cylindrical shell has radius 
(the horizontal distance from the axis of revolution to the curve 
); has height 
(the vertical distance between a point on the 
-axis in 
and the curve ).
Compute the integral.
