You need to show your logic guest. 

3! means 3*2*1 = 6

8! means  8*7*6*5*4*3*2*1

etc

3! is 3 said as  factorial    

Hi Rauhan

Given that the total distance travelled is 1.4 km, and the acceleration is 4m/s^2 for the the first T second, find:

(a) the value of V

(b) the value of T

I will assume that the object is originally at rest at the origin. From time 0 the acceleration is a constant 4m/s^2  

And that after T seconds it has traveled 1.4 km.

There are a lot of assumptions here

\(\ddot x=4\\ \dot x=4t+k \qquad but\;\;k=0\\ \dot x=4t\\~\\ x=(4/2)t^2+c \qquad c=0\\ x=2t^2\\ \text{When t=T, x=1.4}\\ 1.4=2T^2\\ T^2=1.4/2 = 0.7\\ T=\sqrt{7}\approx 2.646\;seconds \)

Hi Solveit,

Gomer can make either 200 gallons of corn liquor or 100 gallons of strawberry wine every six months. {nl}

So it 'costs' Gomer  2 gallons of corn liqour to make 1 gallon of strawberry wine.

Goober can make only 100 gallons of corn liquor or 80 gallons of strawberry wine every six months.

And it 'costs' Goober  100/80=1.25 gallons of corn liquor to make 1 gallon of strawberry wine

a. None of the other answers is correct.

b. It costs Goober 1 gallon of corn liquor to make 1 gallon of strawberry wine .        F

c. It costs Goober 0.8 gallons of corn liquor to make 1 gallon of strawberry wine .   F

d. It costs Goober 1.25 gallons of corn liquor to make 1 gallon of strawberry wine   T

e. It costs Gomer 0.5 gallons of corn liquor to make 1 gallon of strawberry wine      F

I'm going for d too  :))

From a standard​ 52-card deck, how many 4-card hands contain all diamonds?

What is 5 to the power of 2/3

inverse sine is the same as asin

A^n=1.23245^10^5(1+3/5(1-(4/9)^n))=1.23245^10^5/5(8-3(4/9)^n)

\(A^n=1.23245^{10^5}(1+0.6(1-(\frac{4}{9})^n))\\ A^n=1.23245^{100000}(1+0.6-0.6(\frac{4}{9})^n))\\ A^n=1.23245^{100000}(1.6-0.6(\frac{4}{9})^n))\\\)
