Let me try to answer question #2:

Set each part of f(x) = x for the domain of that part.

1)  2x + 1  =  x  for 1 <= x <= 2

        x + 1  =  0

              x  =  -1     Since this value is not within 1 <= x <= 2, there is no answer for this section.

2)  7 - x  =  x  for  2 <  x  <= 3  

          7  =  2x

           x  =  3.5    Since this value is not within 2 < x <= 3, there is no answer for this section. 

3)  10 - 2x  =  x  for  3 < x <= 4

              10  =  3x

              x  =  3 1/3     This is within the domain, so this is part of the answer.

4)  10 - x  =  x  for  4 < x <= 5

           10  =  2x

             x  =  5      This is within the domain, so this is part of the answer.

Answer:  3 1/3,  5

Area is 2-dimensional: it has a length and a width. Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width

\(\frac{1}{3h}-(\frac{2}{3h}-3)=\frac{2}{3h}-6\)

expand brackets

\(\frac{1}{3h}-\frac{2}{3h}+3=\frac{2}{3h}-6\)

multiply by 3h

\(1-2+3(3h)=2-6(3h)\)

take \(h\)s to one side (ie -3(3h))

\(1-2=2-6(3h)-3(3h)\)

-2

\(1-2-2=-6(3h)-3(3h)\)

times out brackets

\(1-2-2=-18h-9h\)

combine

\(-3=-27h\)

\(\times\)-1

\(3=27h\)

multiply by \(\frac{1}{27}\)

\(\frac{3}{27}=\frac{27h}{27}\)

simplify

\(h=\frac{3}{27}\)

common factors

\(h=\frac{3(1)}{3(9)}\)

cancel out

\(h=\frac{1}{9}\)

ta dah!

(2000) x (65000) / 3645

=  130 000 000 / 3645

=  35 665.294 92 ...

1)  Write  32  as  4^b:

      32  =  4 x 4 x 2      2 = 4^1/2

            =  4¹ x 4¹ x 4^1/2  =  4^{1 + 1 + 1/2}  =  4^2½  =  4^5/2

2)  I don't understand "49 ^ x 3 ^ -2".

3)  32 ^ (-3/5)  

      32 ^ (1/5)  =  2   --->   32 ^ (3/5)  =  [ 32 ^ (1/5) ] ^ 3  =  2 ^ 3  =  8

                                 --->   32 ^ (-3/5)  =  [ 32 ^ (3/5) ] ^ -1  =  8 ^ -1  =  1/8

This is how I interpret the problem:

900 x 1/3 =300 students bring their lunch

900 - 300 =600 students do not. So, the ratio of the two would be:

300 / 600 =1/2

If it is "proportional relationship", then the bill for each of the 6 people would be: $294/6=$49.00.

Therefore the total bill for the 14, (6+8), people would be:

14 x $49.00 =$686.00

Me!!!!!!!

Sorry, the function I have to work with is exactly written with " [   ] "

Thanks a lot though!

show your work

\(.6666 = { 66.66 \over 100 } = { 2 \over 3}\)

who knows.

cos 5 =sin (90 - 5) =sin 85

No, i'm not lying, and the teacher really did send me to this site. And she didnt tell me to 'not' talk on here any way i can. Plus i'm in high school, sooo.

Is that why your teacher "sent me to this site"? Or did you make it up?.

you all are wrong the answer is

x=y-3-x-y-z=2x=0

But on this part it says to Express the measurements in scientific notations, i dont know if its the same as you said but thats what it says

By using it's recipricole like lets say you have 5 over 10 would divide it by the ricipricole 10 over 5

yes, it is, Its in a Collage named Santiago Canyon Collage. Search it on google.

5.8 x 10^6  mg/s   x  1gm/1000mg  x 60 s/min = .348 x 10^6 gm/min  =  3.48 x 10^5 g/min

On your previous question, you asked what was sci notation for the number

the density listed is  .00142 g/ml   in Scientific Notation this would be  1.42 x 10^(-3)  g / ml

Well on my paper it says that o.o and i'm stuck on it lolz, and the teacher is busy printing papers atm

1369754*2845031 = 3896992592374

Environmental researchers hypothesize that increasing the number of watering holes will improve the health of a desert biome.  

Which hypothesis would be better for the researchers to use?
