I know the answer to this, it's not homework, but here's the problem: you have 4 fours. You can use them any way you want, as part of a fraction, squared, cubed, anything. You can use numbers like 44, which counts for 2 fours. You can use as many operations as you'd like, but you have no other numbers but 4. (Excluding exponents) Make it so that you find a way to use these in equations that equal the numbers 1-20. It's harder than it looks!

I have a question that asks the lengths of a triangles sides. The length of the hypotenuse is 130 cm, and the area is 3m. Is there a relation between this and its side lengths? How can I figure this out? The answer is 120 x 50, but I need to know how to get to this.

Find zw and z/w. Leave your answers in polar form.

(1) z = 4[cos(3pi/8) + isin(3pi/8)]
w = 2[cos(9pi/16) + isin(9pi/16)]

(2) z = 1 - i
w= 1 - sqrt{3}i

ok so our textbook has this question where its like f(n) is the number of students in your class whose birthday is on the nth day of the year. and the book wanted us to say if this problem was invertible or not. The answer was that it isn't

Ok so our teacher wanted us to think of a situation when this problem would be invertible. So does that mean what is the smallest amount of people you could gather in a room where no two people would share the same birthday? IS that the only way this problem would be invertible?

And how do u figure that number out? I found somewhere that you could have 28 ppl in a room before the probability was .5 meaning that there are 2 ppl sharing the same birthdays??

AHH...god this problem is so confusing
