what exactly is the midpoint formula?? I am taking an oline summer school course in geometery and every website I go to tells me something different for any two points (a,b) and (c,d) the midpoint is ((a+c)/2,(b+d)/2) in words, add up the x's and divide b...

The surface of the sun has a temperature of about 6.0 103 K. This hot gas contains hydrogen atoms (m = 1.67 10-27 kg). Find the rms speed of these atoms.

if the velocity can be expressed as v(t)=1-∛t what is the acceleration function. so i started by bringing in acceleration formula a=v1-vo/t1-to took my velocity function and found the derivative. v=-1/3t^2/3 have i started it correct so far and where do i...

Just making sure im doing things right. suppose that f(x)=2x^2+1/ãx+1/4 x^3-x+1 Caclulate f '(1) So far i have 4x+(ãx^-1)+3/4 x^2-1+0 then i substituted my 1 in and came out with 4 3/4

a box with an open top is to be made from a rectangular piece of tin by cutting equal squares from the corners and turning up the sides. The piece of tin measures 1mx2m. Find the size of the squares that yields a maximum capacity for the box. So far i hav...

y=x^3-3x. Fill out the following table and then make a rough sketch of the graph. I can make the sketch just having trouble understanding what is wanted. y=0 when y'=0 when Relative Max(s) Relative Min(s) y'>0 on the interval(s) y'<0 on the interval(s) y...

Calculate the area between curves y=e^x and y=-e^x on the interval [0,1]

determine the cubic function with 1 point of inflection and no relative minima or maxima.

the area of a rectangle is A=lw. Further suppose l=2w. calculate dA in terms of the differential dw. does this just mean to get the derivative of 2w^2

Does anyone have the answers to Unit 3 Test A Linear Equations and Systems of Equations Test

sorry about that a shouldnt b in there it should be f(x)=(2x^2)+(1/sqrt(x))+[(1/4)x^3]-x+1 the a thing was supposed to be a sqrt but i guess it doesnt copy over from work

I could be wrong but im not sure i came up with 1/4

ok so for instance you have 5/8 all you need to do is divide 5 by 8. whic if you do the math you will get .625. Or even easier to use things that are easy to divide by so 6/10 ok so if you divide 6 by 10 all you have to do is move the decimal so you get ....

a decimal to a percent ok so allyou have to do is take the decimal .625 and multiply by 100 you use 100 because 100% is going to give you the percentage out of 100 which is what we use. so by multiplying by 100 we know that we just need to move the decima...

Percent to a fraction, all you have to do is lets take 85% we put 85/100. so just take your percent set it over 100 and reduce we get 17/20

y=x-a/bz

how did you go from 0= 1/6 (3+-ã3)

that is how I worked it out as well but I did not know if it was that simple I find ways of making simple things hard sometimes thanks for the help

A street that is 164m long is covered in snow. City workers are using a snowplow to clear the street. The snowplow has tires that are 1.5m in diameter. How many times does a tire have to turn in traveling the length of the street?

Not A
