4g-(g-4)= -20       distribute the negative to the terms in the parenthese

4g - g + 4  =  -20   simplify

3g + 4  =  - 20      subtract 4 from both sides

3g  = -24     divide both sides by 3

g = -8

Depends, but likely you can add the memory without any worries.  DDR2 memory stick only uses about 2 watts.   Your CPU, video card and hard drive are the power hungry monsters under the hood.   I have added more memory to every computer I have ever had without a power issue.

When the ball hits the ground, it's height is 0

0 = -16t^2 + 20 t

divide through by 4

-4t^2 + 5t = 0          t(-4t+5) = 0    so t = 0 (when he kicks it)  and  5/4 sec (when it comes back down and hits the ground)

She jumps and initially PASSES the 5 ft deck and comes back down to it:

5 = -16t^2 + 18t    

16t^2 - 18t + 5 = 0     use quadratic formula to find t = 20/32  or  16/32

Since she jumps so quickly initially she jumps PAST 5ft (@ 16/32 sec) and comes back down to the 5 ft level at 20/32 sec

wait CPhill, you actually asked this question? (I'm joking lol. I know what you actually mean by thanks, as in thanks for saving people time and answering this question).

well good to see you too. feels good to be back!

You will need the initial velocity (usually 0) and the velocity at the point you are interested in:

x = xo + vo t + 1/2 a t^2     xo = original position.....ususally 0    t = time   a = accelration of gravity (9.8 m/s^2)

Well, we can have 1,000,000 consective composite numbers as follows:

1,000,001! + 2

1,000,001! + 3

1,000,001! + 4...........and so on till.....

1,000,001! + 999,999

1,000,001! + 1,000,000

1,000,001! + 1,000,001

Does this make sense to you?

( 1 1/3) oz / 20 tsp  =

(4/3) / 20 =

4/60 =

1/15 oz / tsp

a)  height  = w + 1     length = w + 5

b) V   =  width * height * length.....so we have

2112 =  w * (w + 1) * (w + 5)

Thanks, Heather....BTW....good to see you....!!!

Press "2nd" key first. Then you should see % sign, in the top row to the left. Example: 150 + 5% =Enter 150, then + key, then 5, then % key followed by = key.

Nevermind, I have found the answer!

Pi (oddly enough) = 4 - 4/3 + 4/5 - 4/7 + 4/9 - 4/11 + 4/13 - 4/15 ...

The only odd thing about the above (other than it being like that) is that I learned about it on NETFLIX!!! Who knew you could learn anything from there?

There can be any number of digits after a decimal point, not just one or two. It all depends upon the dimensions of the item that you are calculating the volume of. If you are calculating the volume of a prism, this formula always works: volume = base * height, where the base is the surface area of the bottom or top of the prism.

610/531 - Cannot be reduced any further.

610/531 =1 79/531 - as a mixed fraction.

thanks

Number of grains on the 64th square =2^(64 - 1) =2^63 =9,223,372,036,854,775,808 grains.

9,223,372,036,854,775,808 / 1,100,000 =8,384,883,669,867.978 - bushels of grain on the 64th sq.

8,384,883,669,867.978 x $3.90 =$32,701,046,312,485 - or $32.7 trillion dollars.

type asin(x), where x is the degrees

this also works for cos (acos) and tan (atan)

You would need to find how many grains are on the 64th square then multiply that by the price after dividing by 1.1 mil.

1/4 mile swim=1 mile run (calories)

1 mile swim=calories burnt in 4 miles running

Juan swims 5 miles a day

5*4=20

A: 20 miles must be ran to use same number of calories used in the 5 mile swim Juan does.

ps wow thats a lot of miles

What's the function?

f(5) means that for every x in the function you will substitute the number 5.

1/2*2=1*6=6+1.7=7.7

10^-6=1/10*1/10*1/10*1/10*1/10*1/10=0.000001 or 1/100000

Area  of the octagon  =   2 ( 1 + sqrt (2) ) * side^2.....so we have

2 (1 + sqrt (2) ) (8)^2  =

128 (1 + sqrt(2) )  ≈  309  sq in

The two semi-circles will have the same total area as a circle with a radius of 4 in....so their total area  =  pi * radius^2   =  pi * (4)^2  =   16pi sq in 

So....the total area ≈  ( 309 + 16pi) sq in  ≈ 359.3 sq in
