Whoops! I accidentally thought that $55 was in need of marking up. Thanks for the correction! 

I agree with Anon until the final step.

After calculating 20% or $55.00 and getting $11.00, I believe that you should subtract $11.00 from $55.00 to get the cost to the store of $44.00.

(This assumes that the markup rate is applied to the final price of the item and not to the original cost to the store.)

The vertex is equidistant from the focus and the directrix......so in this case, the vertex is just [(1+7)/2 , 3) =

(4, 3)....BTW...this parabola opens to the left.....

sure

y-2=7--4

positive two

4*7=28 

19. 19, people!

20% is 1/5 of 100%, which means that we must add 1/5 of the $55 to $55. 55/5 is 11, and 55 plus 11 is 66, which means that the new price is $66.

1/2 times 8/1 is 4, and 4 times 58 is 232.

1 divided by 0 is undefined.

you cannot divide any number by 0

If anyone is dumb here it is the anon who has never considered this question before and who STILL did not consider it when it was put right in front of his/her nose.

the answer is 0.186041067853825.

okay NOW I have worked out what the question is!!!!!  

P is a moving point in a rectangular coordinate plane such that the perpendicular distance from P to L1:x=3 is equal to that from P to L2:y=3.Suppose the locus of P is denoted by F and the slope of F is negative

INTERPRETATION

L1 is  the line  x=3,    L2 is the line y=3

P is a moving point in a rectangular coordinate plane such that the perpendicular distance from P to L1  is equal to that from P to L2  Suppose the locus of P is denoted by F and the slope of F is negative

a.)Describe the geometric relationship among F,L1 andL2.

b.)Find the equation of F

a.)Describe the geometric relationship among F,L1 andL2.

b.)Find the equation of F

the answer is 232.

arc cos is the same as inverse cos.

Just use  acos

Good thought. I should have done that. Thanks, CPhill. 

Pi? 9+10=Pi?

You can easily access the calculator on the page and use it by clicking on the "Home" tab or the page logo on the top of the page.

5^6,000,000,000,000,000,000,000,000,000,000,000,000 might not be available, but you can try it.

Assuming you mean 24,700 (twenty four thousand seven hundred) 24700 / 9.5 (because the first shift was 1 amount, second shift was 8.5 X that, making it 9.5 groupings all up. so

24700 / 9.5 = X

X * 8.5 = shift 2 production

3 and 1/4 would become 13/4 since 3 times the denominator, 4, is 12, and that plus the current numerator, 1, is 13, becoming the new numerator.

Converting 1/2 into 4ths is 2/4, and 13-2 (the numerators of the numbers) is 11. That means that 3 and 1/4 minus 1/2 is 11/4, or 2 3/4.

Explain.

Let's replace _ with "x".

-18/x = 3

-18/x * x = 3 * x

-18 = 3x

-18/3 = 3x/3

-6 = x

We now know that "x" or _ equals -6.

It is horrible when the obvious letter to use eg P for pencil and P for pen does not work (because they are the same)  If you can swap them for some other letters that still makes sense, like I did, then it gives you one less thing to get really confused about.

1/2 times 1/2 is 1/4.

1/4 times 1/2 is 1/8.

1/8 times 1/2 is 1/16.

1/16 times 1/2 is 1/32.

1/32 times 1/2 is 1/64.

Therefore 1/2 times 1/2 times 1/2 times 1/2 times 1/2 times 1/2 is 1/64.

-18 / -6 = +3

your answer = -6
