Just so you know, CPhill and Melody rarely make mistakes (especially on easy questions, like this one) unless the question asker or others attempting to answer it have CDD –that is Contagious Dumbness Disease. There is at least one other on here who has it. They almost caught it from him.

This is a horrible disease – it is worse than cooties! Even if you are cured, many will think you still have it and avoid you like the plague. I caught it from someone, and though I am cured now, I have an antibody that causes nausea when I am around anyone that has it. That’s a good thing though, because it helps to keep me from becoming reinfected.

If CPhill or Melody get it and recover, they may avoid you because of the nausea inducing antibody. Similar to having doctors avoid you, it will take longer to find a cure. In the worst case, you may never find a cure; that means a lifetime of perpetual dumbness.

$${\frac{{\mathtt{215}}{\mathtt{\,\times\,}}{\mathtt{50}}}{{\mathtt{100}}}} = {\frac{{\mathtt{215}}}{{\mathtt{2}}}} = {\mathtt{107.5}}$$

We have

50 = P_o(1.02)²      where P_o is the original population.......divide both sides by  (1.02)² 

50 / (1.02)² = P_o = about 48

So.....the population  at t = 2.1  =

48(1.02)^2.1 =  still about 50

This is explained by the fact that the population is small and the lapse of time between 2 and 2.1 is also small......

F(1+2+3+4+5)  = F(15) = 610

BTW.......we can calculate any Fibonacci number with index "n" using this formula....

[Phiⁿ - (-Phi)^-n ] / √5   ....where Phi = [ 1 + √5 ] / 2

The odd thing about this "formula" is that it looks as though it should produce some irrational number........but it doesn't !!!!

Try the formula with n = 15 and see if it doesn't give you 610.......

h**l is not nececaraly a curse word

You are amazing!! Thank you so much! :))) I hope you have a wonderful evening! 

ok lets see 1+1=2 so 2+2=4 ✌+✌=4⃣1⃣

So we have

.4=cos2(pi)t  

Using the cosine inverse, we have

cos^-1(2pi(t)) = .4       let (2pi)t = x

cos^-1(x) = .4

x = 1.159

So x = (2pi)t = 1.159   divide both sides by 2pi

t = 1.159/ (2pi) = about 0.184

chillin like a chinchilla

I'm like butter cus im on a roll.

good and u

"Of" means multiply     125%  = 1.25      so we have

1.25 * 60   = 75

1. 2.100


2. 2.200


3. 2.300


4. 2.175

Thank you guys! I was able to get the right answer with your help! :) 

I have one other question for you! 

the question is: Let the equation below model the electromotive fore in volts V at t seconds

V=cos2(pi)t

find the least value of t where t is less than or equal to 1/2 and greater than or equal to 0 for V=0.4

I know the answer to this is t=0.18 however i dont know how they got that answer! 

Thanks again for your help :)

2 + 1/4 =   9/2

So .... (9/2) * (-8)  =   -72 / 2  = -36

a question mark or words

Rounded to 100ths = 2.18

Rounded tp 10ths = 2.2

Rounded to the nearest integer = 2

I just divided by the -2 instead of distributing it.....check my answer...I think you'll see it's correct.....

150% = 1.5    "of" means "multiply"   "what" means "n"  "is" means "="

So we have

1.5 x n = 30     divide both sides by 1.5

n = 20

This just says to raise 10 to the power of 1.56

Key in 1.56

Hit the 10^x key

Hit enter

See if that works......

sin(sin^-1(1/4)+tan^-1(-5))     Let sin-1(1/4) = A   and let tan-1(-5) = B

So we have

sin(A + B) =  sinAcosB + sinBcosA 

Note that, since the tan-1 is negative, B must lie in the 4th quadrant. So the cosB = 1/√26  and sinB = -5/√26.  And cosA = √15/4......so we have

sin(A + B) = (1/4)(1/√26) +  ( -5/√26) (√15/4.) = (1 - 5√15)/ (4√26)

move 10 to the other side and add it to 6

It is time to stop monkeying around for a little while and say Hello, to everyone . . . . . . . . . . . . .

Hi Happy.

Hi Rosala, It’s great you have returned, we’ve all missed you.

Hi Patsy, I like your dog. He seems very friendly. :)

Here’s one of my dogs. His name is Oscar. Short for Oscar Mayer wiener dog. That’s his favorite food. You are what you eat. Right?

I’m kind of surprised I don’t look like a banana or a peanut.
