U guys are smart but i am not... i need help, please help me

precalculus
thank you :)

precalculus
find lim y. and lim y x->infinity. x-> negative infinity 1.) y= (x + sinx)/x 2.) y= x/ (1+ 2^x)

PRECALCULUS
thank you guys so much! I had a really hard time with these. I appreciate it :)

PRECALCULUS
1.) determine two pairs of polar coordinates for the point (-4sqrt3, 4sqrt3)with 0degrees less than or equal to theta less than or equal to 360degrees 2.) Use DeMoivre's Theorem to find (1-i)^10. write your answer in the form a+bi. 3.) Find the cube roots of -8. Write your...

I dont see the link. I dont think this website allows you to put up links

precalculus

Precalculus
fin the product z1 * z2 and quotient z1/z2 using the standard form for z1 and z2. z1 = 2 - 3i and z2 = 1 - sqrt 3i

PRECALCULUS
thank you

PRECALCULUS
what do you mean?

PRECALCULUS
write the complex number in standard form a+bi sqrt 7 (cos pi/12 + i sin pi/12) (sqrt = square root, i= imaginary number)

PRECALCULUS
write the complex number in standard form a+bi sqrt 7 (cos pi/12 + i sin pi/12) (sqrt = square root, i= imaginary number)

PRECALCULUS HELP PLEASE!
thank you soooooooooo much

PRECALCULUS HELP PLEASE!
convert the polar equation to rectangular form. 1.) r sec(theta) = 3 2.) r = 4 cos(theta) - 4 sin(theta) convert from rectangular equation to polar form. 1.) x^2 + (y-1)^2 = 1 2.) (x-1)^2 + (y+4)^2 = 17

Physics
It would collapse, because you have to exert a downward force to go up. By pushing down on the cardboard that barely holds you, it will probably collapse.

Economic Stability
An economy with fairly constant output growth and low and stable inflation. Basically, there is not too much money being lost, and the money coming in is at a good level. Good enough that there are not too many problems. Does that make sense?

trig
type into google "coolmath graphing calculator" then on the calculator, just type in -4 cos(x/2 + 3.14) + 1 and then press enter on your keyboard. the graph should show up.

Algebra
2/3, because there are 3 coin flips, but one is already tails, so there's only 2 more chances to get heads.

type in "crossword solver" in google
