79sq miles is the perimeter of your left pinkie

143/100.

It's hard to answer this without more information, but a 'finger width apart' is pretty narrow, so assuming you have bite marks on something or a skull, I'm guessing a raccoon, skunk, or weasel - something with pretty well developed fangs (a carnivore) and small. What do you have to provide more information, color of the animal, size ...

There are 10 millimetres in one centimetre. Therefore, 2000 millimetres is equal to 2000 / 10 = 200 centimetres.

Google, or a maths teacher.

Could you be slightly more specific as to the help you require?

1/2*tan(x)^(1/2)/(cos(x)*sin(x))^(1/2)*cos(x)*2^(1/2)*arccos(cos(x)-sin(x))-1/2*2^(1/2)*ln(cos(x)+2^(1/2)*tan(x)^(1/2)*cos(x)+sin(x))

try this Could be your battery is losing power when turned off and is charging. This would only be a few hundred revs. Do you have anything extra left turned on when car is not running like stereo, amp, etc.

The F-ratio can be expressed as a function of the R^2 only under certain assumptions (e.g. linear regression model). There are econometric models where the R^2 is not meaningfully defined or the F-ratio cannot be expressed in terms of the R^2, but you can still carry out an F-test, .

You could have a bbq or picnic as well as movies, have a dance, play some sort of games, do each others hair and makeup if permitted by your parents, tell ghost stories in the dark, if you have a pool go for a swim or have a water fight outside (could use water balloons too) play outdoors games such as frisbee, etc. Use your imagination you can do anything within reason that's fun - Hope this helps!

There are llots of fun things you could do. You may want to pick a theme, and have some games revolve around that. For example, you could have a Hollywood Star theme party, where everyone comes as their favorite "star". You could try to guess who each other is, make plaster hand prints, etc. See the link below for a great list of ideas!

56 ounces is 3.5 pounds

Fourth root of pi, or 3.141592654 0.25 = 1.33133

x2 - 8x - 40 = 0

∴ x2 - 8x = 40

∴ x2 - 8x + 16 = 56

∴ (x - 4)2 = 56

∴ x - 4 = ± 561/2

∴ x = 4 ± 561/2

∴ x = 4 ± 2 × 141/2

∴ x ≈ {11.4833, -3.4833}

The two rational solutions are (0,0,0) and (1,1,1). There are no other real solutions.

I know the answer

*is arctan(x), but how about breaking it into partial fractions by doing 1/(1-ix)(1+ix)?

How do you not know this?

y = 3.

y^3 - y = y(y^2-1) = y(y+1)(y-1) = 3*4*2 = 24.

I apologize, for the person who first answered this question is only aware of his own skills at math, and is unaware that not everyone understands very advanced math, but he is correct, that is the answer.

Prime numbers, like 7, have no proper factors. The only factors are 1 and 7.

The derivative of a function tells you how it changes in response to a change in a specific variable. The derivative of a linear function (like y = 2x + 3) with respect to its independent variable is the slope of the line (in this case, two): how much the line rises or falls when "x" changes by one.

The expression 8x2 does not involve any variables, and thus never changes. Its derivative is therefore zero. There is no variable involved, so the result is always 16. Changing the input variable (of which is there is none) has zero effect on the answer.

I don't really understand what your question means, but we'll go through the complete step of solving linear inequalties.

For example, x - 3 < 5. What is x?

Well, we must isolate 'x' on one side. We do it like we do with an equalty.

x - 3 + 3 < 5 + 3 -->> x < 8

There we have it, the solution!

Of course, inequalties aren't exactly like equalties, either. Take this for instance:

-x < 5

We need to isolate x, so here we go: x < -5. Oops, we messed up somewhere!

It turns out, that if you take the equation and multiply or divide by a negative number, we get to reverse the inequalty sign. Therefore, the answer is: x > -5. There we go.

x2 - 6x + 5 = (x - 1)(x - 5)
