Nope .... team 1  was  33 -7 in the second half season    team 4 was 28 - 12

Richard an Elaine McCormick would like to have 20,000in5yearstomakeadownpaymentonahome.Theydecidetosave 20,000in5yearstomakeadownpaymentonahome.Theydecidetosave 350 at the beginning of each month for the next 4 years. The money is in an account that pays 6% compounded monthly. How much will they need to save in the fifth year?

Smart Aleck: Why did join words together, which makes it difficult to read? Do you need help? 

The McCormicks will save a total of $19,028.91 in 4 years. Therefore, they need to save in the 5th year a total of: $20,000 - $19,028.91=$971.09

Well     2k = -12     so k= -6      -w^2 = 81    so w =9 or -9   2f = -14   so f = -7 

That should read  2m/sec^2      2 m/sec is a VELOCITY

Two people.

1 man plus 1 woman=YOU !!!!!.

what is 10.5y / 5y - 3 divide both sides by 5

=(2.1 y)/(y-0.6)

yep

-16

What is 2n - m=2n - m !!!!!!!!!!.

Sorry, Dragonlance........."mule muffins" won't do.......!!!!!!

Thankk you!! 

Haha!

 -4  5  6

   0  4  4

 -2  -5  4

This explains the procedure........http://www.purplemath.com/modules/determs2.htm

Rewrite  the first two columns again

 -4   5   6   -4   5

  0   4   4    0   4

 -2  -5   4   -2  -5

As explained in the PurpleMath resource, multiply down the diagonals and add the results

[ (-4* 4 * 4 ) + (5 * 4 * -2) + (6 * 0 * -5) ] =  [ -64 + -40 + 0]  = -104

Now, multiply "up" the diagonals  and add the results

[ ( -2 * 4 * 6) + ( -5 * 4 * -4) + ( 4 * 0 * 5)]  = [ -48 + 80 + 0]  = 32

Take the first result and subtract the second  =   -104- 32  = -136

So.......the determinant  = -136

A horse speeds up from a speed of 11 m/s to 17 m/s in 3 seconds. What is the horse's acceleration?

17 - 11=6m/sec. in 3 seconds. Therefore,

6/3=2m/sec. horse's acceleration.

When Alice Dill and Donald Nash married, they set a goal to have $1,000,000 on their 50th wedding anniversary. If they could earn 6.6% interest compound monthly in an ordinary annuity, how much would they have to save monthly to reach their goal?

Alice and Donald would have to save=$212.61 per month.

The formula you use for this is: PMT=FV{[[1 + R]^N - 1]^-1. R}=PMT NEEDED TO SAVE $1 IN THE FUTURE, Where R=Interest rate per period, N=number of periods, P=periodic payment, FV=Future value.
