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

Answer:
JL = 50
Step-by-step explanation:
Since K is the midpoint of JL , then
JK = KL , substitute values
6x + 7 = 9x - 2 ( subtract 6x from both sides )
7 = 3x - 2 ( add 2 to both sides )
9 = 3x ( divide both sides by 3 )
3 = x
Thus
JL = JK + KL
= 6x + 7 + 9x - 2
= 15x + 5
= 15(3) + 5 = 45 + 5 = 50
f(t) = 2(0.4)^t
F(-2) means to replace t with -2:
f(-2) = 2(0.4)^-2
f(-2) = 12.5
