Chemistry
Ionic bonds and covalent bonds: Ionic Bond(s) for: K&S -> K2S N&Be -> Be3N2 Al&P -> AlP Covalent Bond(s) for: C&F -> CF4 S&O -> OS Cl&Se -> SeCl4

Calculus
Find the measure of feta, to the nearest degree where o degrees is less than feta which is less than 360 degrees. 6 sin feta = -1 I really dont get how to solve, I hate algebra, and I feel that it's gonna be getting used in this question.

Velocity and Displacement
A stone falls freely from rest for 8.0s. A. Calculate the stone's velocity after 8.0s. V2-V1+at V2 = (0) = 9.8(8.0) V2 = 78.4m/s B. What is the stone's displacement during this time? d = (v2 + v1)t/2 d = (78.4 + 0)/2(8.0) d = 313.6m

Calculating Distance
If you drop a golf ball, how far does it fall in 0.5s? Is the correct formula to use?: D = V1 + t + 1/2at^2. But the problem is that I dont know the acceleration, would that be 0?

Finding Velocity
A brick falls freely from a high scaffold. A. What is its velocity after 4.0s? B. How far does the brick fall during the first 4.0s? I don't know what formula to use. I only have time, and I guess the first velocity would be 0s.

Physics
A car is travelling on a highway Can it have a negative velocity & a positive acceleration at the same time? Can the car change d direction of its velocity when travelling with constant acceleration?

English
You only have to capitalize it if you're starting a sentence with that word, otherwise it stays lowercase.

Velocity and Acceleration
A car is travelling on a highway Can it have a negative velocity & a positive acceleration at the same time? Can the car change d direction of its velocity when travelling with constant acceleration?

Calculus
2^3V4(2^3V54-^3Vx) is equal to 16, then x is equal to... I simplified the 2^3V4 and got 64, and just got stuck.

Calculus
5-3ã2 multiplied by its conjugate is... Its supposed to be 7, but I dont get how to do this, cause now im totally confused, i thought that the conjugate came when you were to rationalize a denominator... I did this... 15ã2-9ã4 15&at...
