What's the recursive formula of the geometric sequence below?
yKpoI14uk [10]

Answer:

Hey there!

We have an=a1(r^n-1), which is the formula for a geometric sequence.

The common ratio is 3, and 2 is the 1st term.

Thus, we have a1=2(3)^(n-1)

Hope this helps :)

Graph a line with a slope of 3/4 that contains the point (2,-3).
arsen [322]

Answer:

Step-by-step explanation:

First, plot the point (2, -3) on the graph.  Then, use the slope to pick another point.  The slope is rise over run.  For your slope, the line will go 3 places up and then 4 places to the right.  Using a straight-edge, follow the points and you will get the graph of the line.

OOOO
lbvjy [14]

Step-by-step explanation:

Given bi-quadratic equation is:

x^4+95x^2 -500=0

Substituting x^2=a, given bi-quadratic equation reduces in the form of following quadratic equation:

a^2 +95a -500=0\\

Let us factorize the above quadratic equation:

a^2 +95a -500=0\\\therefore\: a^2 +100a -5a-500=0\\\therefore\: a(a +100) -5(a+100)=0\\\therefore\: (a +100)(a -5)=0\\\therefore\: (a +100)=0\:\: or \:\: (a -5)=0\\\therefore\: a = - 100\:\: or \:\: a = 5\\\\CASE\: (1)\:\\When\: a = - 100 \implies x^2 = - 100\\\therefore x=\pm \sqrt{-100}\\

Since square root of a negative number cannot be found, so:

x \neq \pm \sqrt{-100}\\

CASE\: (2)\:\\When\: a =5 \implies x^2 =5\\\therefore x=\pm \sqrt{5}\\

Please help me I put 100 points for anyone who helps me
LenaWriter [7]

Answer:

a)

<u>The discount id 40%, so the function is:</u>

  • d = 0.4p

b)

  • p = 100 ⇒ d = 40
  • p = 200 ⇒ d = 80
  • p = 300 ⇒ d = 120
  • p = 400 ⇒ d = 160
  • p = 500 ⇒ d = 200

<em>The graph is attached</em>

c)

  • p = $85 ⇒ d = 0.4*$85 = $34

<u>Sale price is:</u>

  • CP = p - d = $85 - $34 = $51
