:)if it is wrong sorry
Answer:
Step-by-step explanation:
Volume of a cylinder = pi*(xx)^2*yy
= x^4*pi*yy
Volume of a cone = 1/3*pi*(9x^2)^2*h
= 27pi*x^4*h
x^4*pi*y^2 = 27pi*x^4*h
h = y^2 / 27
Hello,
y=k*x ; if x=1.2,y=12
==>12=k*1.2==>k=12/1.2==>k=10
Answer:
<u>2x−15</u>
7x+10
Step-by-step explanation:
3x squared cancels out then you are left with
<u>6x-45</u>
21x+30
then you simplify and get <u>2x-15</u>
7x+10
