Answer:
diameter / 2 = radius
3 / 2 = 1.5
radius x radius x height x pi = volume
1.5 x 1.5 x 6 = 13.5
We don't multiply by Pi because it is already included
Hope this helps
Step-by-step explanation:
Answer:
y=-5x+28 general form
slope point :y-(-7)=-5(x-7)
Step-by-step explanation:
definition :perpendicular slopes are negative reciprocals of each other
x-5y-2=0
y=1/5 x-2/5
slope of the perpendicular line =1/m=-1/(1/5)=-5
slope point :y-(-7)=-5(x-7)
find b :
y=-5x+b
-7=-5(7)+b
b=-7+35=28
y=-5x+28
y=1/5 x-2/5
Answer:
No solution
Step-by-step explanation:
x^4 and x^2 and 11x^2 are always >=0
even x = 0
0 + 0 + 18 > 0
so no solution for this equation
Done :))
Answer:
Step-by-step explanation:
First option-->X=-1
2·(-1)-2=-4
Second option-->X=-4
2·(-4)-2=-10
Third option-->X=-3
2·(-3)-2=-8
Fourth option-->X=0
2·0-2=-2
Fifth option-->X=4
2·4-2=6
The last one is the only one positive
