?

there is an example saying that:

John works between 10 and 30 hours per week at a restaurant. he earns $6.50 an hour, but he can earn tips when he delivers pizzas?

I understand the inequalities but why the inequality here as 10 ≤ t ≤ 30 is solid? it should be as 10 < t < 30.

I am understanding that if we have two dimensions, we make it as a solid, but if it is one dimension, it is open or dashed. can someone agree or correct?

I can tell how to find a phi from a square, which then can be called as a golden rectangle.

but the problem is, i watched on youtube that a small piece can be cut into two pieces. then:

_____________________

A . . . . . . .. . B. . . . . . . C

AC/AB = AB/BC

so i picked AC = 2, AB = 1.1 , BC = 0.9

If I apply the ratio, it won't get close to the 1.6180

another question? do all the rectangles apply to the golden ratio?

thank you all :)

all the time say that it is carmer's rule not cramers rule? does it mean wrong ?

Residuals tell us how our model is a good fit. if we see our residuals are graphed as curved, then our model is not a good fit.

If we see our residuals are randomly plotted, then our model is considered a a good fit.

what if I have a horizontal residuals? do they consider my model as a best fit?

please provide more info if you have.

Thank you :)

if we have an equation that has all real number as a soultion:

all real numbers <------ agree

(-∞ , ∞) <------ agree

{ x I x = all real numbers } <------ can i set it up a this?

y > x^2 + x - 20 <----- the graph will be dash line

y ≥ x^2 + x - 20 <----- the graph will be solid

both these equations will be shaded inside the parabola

0 > x^2 + x - 20 <----- the graph will be (I don't know: the book and other sources show solid) (not forgetting to exclude the solution; thats right....but what about the graph itself, should not be dashed?

0 ≥ x^2 + x - 20 <----- the graph will be for sure solid

(both these equations will be shaded below the x-axis and only inside the parabola)

(8)^(1/3) = 2

(- 8)^(1/3) = - 2 <----- is this true??????

if so, why wolframalpha doesn't show the real root? is there a trick somewhere?

If I have an equation as 3x^3 - 2 = 0

the roots are as the following:

3 * ( x^3 - 2/3) ) = 0

x^3 - (2/3) = 0

(x - (2/3)^(1/3)) * (x^2 + (2/3)^(1/3)x + (2/3)^(2/3)) = 0

(x - (2/3)^(1/3)) = 0 ----> x = (2/3)^(1/3)

(x^2 + (2/3)^(1/3)x + (2/3)^(2/3)) = 0 ---> quadratic equation and I came up with:

- (2/3)^(1/3) * [ (1+/-i√(3) )/ 2 ]

BUT, the wolfram alpha shows in the following link:

http://www.wolframalpha.com/input/?i=3x%%E2%80%A6

how they have gotten the complex roots?

if I use my TI-89 Calculator, it won't show the imaginary root for the equation 3x^3 - 2 = 0 ? any idea?

thank you :)

if I have two equations which are :

y = x + 2 & y = 2x + 1 <-------> how am i gonna find the intersection point on the chart to be shown?

what if I have 2x + 3y = 2 & 4x + 9y = 5. . . .can the chart shows the value of the intersection point?

if I have two equations which are :

y = x + 2 & y = 2x + 1 <-------> how am i gonna find the intersection point on the chart to be shown?

iPod touch. I am looking for app which can show a slow motion in clear picture ( High Quality ) for a RECORDED VIDEO not Movies. i have tried the following app and weren't high quality of the image:

Video pix, slow timer, speedup - v1.4 , speedup TV - 1.6.3 , splice . <====> all these app had the slow motion but weren't in high quality ( clear picture ).

please help. :)...thank you :)

i know what does the case number is, but I don't know what "on Envelope" means. how to proceed it?

this question or statement is in the following link:

it is # 2.

thank you so much...:)

how would you monopulate the left hand? only you can play with the left hand side.
