Answer:
Domain: (−∞,∞),{x|x∈R}
Step-by-step explanation:
the domain will be Domain: (−∞,∞),{x|x∈R} because
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
Answer:
I don't see the number line
Step-by-step explanation:
i would love to help you out, but I don't see the number line I'm supposed to be referencing.
Here
radius( r) =12/2=6 in.
height(h)=13 in.
now,
volume of hemisphere(V1)=
volume of cylinder(V2)=
now total volume=V1+V2
=144Pi +468pi
=212pi
It would take 5 yrs. for both trees to be the same height.
We have from Thales theorem that because the 2 triangles are similar, JM/JK=JN/JL. We have that JN=x, JL=x+24 and that JM=7 and JK=28. Substituting, we get:
x/(x+24)=7/28.
Hence, x/(x+24)=1/4. This leads to 4x=x+24, 3x=24, x=8. We have solved for x=JN and this is equal to 8.
