Frequency, f, is how many cycles of an oscillation occur per second and is measured in cycles per second or hertz (Hz). The period of a wave, T, is the amount of time it takes a wave to vibrate one full cycle. These two terms are inversely proportional to each other: f = 1/T and T = 1/f.

Answer:
6.5 seconds.
Explanation:
Given: h=-16t²+679
When the object reaches the ground, h=0.
∴ 0=-16t²+679
collecting like terms,
⇒ 16t²=679
Dividing both side of the equation by the coefficient of t² i.e 16
⇒ 16t²/16 = 679/16
⇒ t² = 42.25
taking the square root of both side of the equation.
⇒ √t² =√42.25
⇒ t = 6.5 seconds.
Punnet squares were only recently added into the curriculum. They allow a more organized/ efficient way to do binomial, or polynomial multiplication. They may also be known for being used in biology to show what genes an offspring could potentially have.

For number 3, I believe it is B, as people subconsciously get the name Levi's into their head. When people say I want to go to Levi's stadium for a game, they connect it with good thoughts, and next time they want to get jeans they might think, what jean brand do I know, and think of Levi's.
For number 4, I believe it is D. A is untrue, and B and C have nothing to do with the exchange of information between consumers.
For number 5, it is C, Monopoly. Monopolies are when 1 company is the only one who sells a particular good or service. There are some monopolies, but most of them are by federal agencies and consumers most likely do not want to choose for those services.
For number 6, I believe it is A, right to consumer education. I originally thought it might be B, however, when I looked up B, there was no such law, and what came up is the right to consumer education. I am not 100% sure on this one, but your best bet is A I think.
Hope this helps!
