Suppose $x$,$y$, and $z$ form a geometric sequence. if you know that $x+y+z=18$ and $x^2+y^2+z^2=612$, find the value of $y$.
OverLord2011 [107]
Because x,y,z form a geometric sequence,  therefore the common ratio is
r = y/x = z/y
That is,
y² = xz                            (1)

We are given:
x + y + z = 18
Therefore
x + z = 18 - y                 (2)

Also,
x² + y² + z² = 612
Therefore, from (1), obtain
x² + z² + xz = 612 
(x + z)² - xz = 612
From (1) and (2), obtain
(18 - y)² - y² = 612
324 - 36y + y² - y² = 612
-36y = 288
y = -8

Answer: y = -8

What is the constant of proportionality that relates the number of cookies made, y, to the number of cups of sugar used, x ? A r
dmitriy555 [2]

Answer:

24


Step-by-step explanation:

Direct variation (with constant of proportionality) has the form:

A=kB

Where,

  • A & B are the 2 variables being compared
  • k is the constant of proportionality

Using cookies, y, and sugar, x, we can write:

y=kx

Substituting y=96 and x=4, and solving for k, we have:

96=k(4)\\\frac{96}{4}=k\\k=24

Thus, constant of proportionality is 24
