Cos Ф - cos Ф.sin² Ф

sin² Ф = 1 - cos² Ф
cos Ф - cos Ф( 1-cos² Ф) = cos Ф - cos Ф - cos³ Ф = cos³ Ф

cos Ф - cos Ф.sin² Ф = cos³ Ф

Y=8(x^2+4)+17+-32 in vertex form

Yakvenalex [24]

$y = 8( {x}^{2} + 4) + 17 + ( - 32)$
$y = 8( {x}^{2} + 4) + 17 - 32$
$y = 8 {x}^{2} + 32 + 17 - 32$
$y = 8 {x}^{2} + 17$
compare to the formula:
$y = a( {x}^{2} - h) + k$
$y = 8( {x}^{2} - 0) + 17$
a = 8
h = 0
k = 17

How will the solution of the system y > 2x + 2/3 and y < 2x + 1/3 change if the inequality sign on both inequalities is re

Valentin [98]

Answer:Infinite solution

Step-by-step explanation:

For Inequalities

$y>2x+\frac{2}{3}$

3y-6x>2

and $y$

3y-6x<1

The required Inequalities have no solution because they do not share the common region for a common solution

But if signs of both inequalities is changed then the system has infinite number of solution.

$y$

3y-6x<2

and $y>2x+\frac{1}{3}$

3y-6x>1
