Using the ratio of pretzels to peanuts, it is found that a graph with a slope of 0.6 best represents the ratio of pretzels to peanuts in each bag.
The ratio of amount a relative to amount b is given by a divided by b, that is:
In this problem, we have a ratio of <u>3 ounces of pretzels to 5 ounces of peanuts,</u> thus the graph has a slope of:
The graph that presents this situation, with a slope of 0.6, is sketched at the end of this answer.

Start by getting everything on the same side of the equals sign and then set it equal to 0.
. Factor out the common tan^2x like this:
. Now we have 2 separate equations to solve:
and sinx = 0. Now we have to figure out where tan^2 is 0 between 0 and 2pi. If we include 2pi, the solutions for that equation are
. You can test those out on your calculator just to be sure. There's only one value of x for the next equation. The only place between 0 and 2pi where the sin x = 1 is at x =
. And there you go!
Answer:
x = ±
Step-by-step explanation:
Given
3x² + 2 x - 5 = 0 ( add 5 to both sides )
3x² + 2 x = 5
Before completing the square we require the coefficient of the x² term to be 1
Factor out 3 from each term on the left side
3(x² + x ) = 5
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² + x
3(x² + 2( )x + - ) = 5
3(x + )² + ( 3 × - ) = 5
3(x + )² - = 5 ( add to both sides )
3(x + )² = ( divide both sides by 3 )
(x + )² = ( take the square root of both sides )
x + = ± = ± ( subtract from both sides )
x = - ±
Thus
x = - - = -
x = - + =
