I have a skateboard from a long time ago, and I want to use it only for cruising (no tricks) it appears that I, on the skateboard, am skateboarding very slow. Would a pennyboard be easier or faster than a regular skateboard? Or should I just keep my old skateboard? Any tips for balancing or anything else regarding skateboards in general? Should I just suck it up and keep practicing? I'm 5'1 with women's 7 size feet if that makes a difference? Sorry just rambling at this point, but yea, Thanks

Please explain as well as possible

why allenes are achiral,

and why adding substituents would cause it to become chiral.

Thank you in advance

(a) NO3- + 10H+ → NH4+ + 3H2O

(b) Cl2 + 4H2O → 2ClO2- + 8H+

Don't just give the answer, please explain as thoroughly as possible so I can know how to solve these for future reference.

Thanks in advance!

I've been collecting the icon series for the city, state, and country Starbucks mugs for a while, but after visiting some Starbucks, I've noticed that they don't have those in the shop anymore, they have a different and not-as-great design, the you-are-here series. Has Starbucks discontinued the icon mug series and replaced it with the you-are-here series??

Here are what the icon series looks like: https://www.google.com/search?q=starbucks+city+mug...

Any additional helpful comments are appreciated. Thank you!!!!

Find g(x+h) for g(x) = 3x^2 -4x +6.

How would you go about doing this problem?

... I'm really confused. My teacher didn't provide h(x).

Please explain thoroughly, thanks!

If sin x = -(4/5), and tan < 0, what is (a) cos x = ? (b) sin -(x) = ? (c) Csc x = ?

Especially for a, how do you find cos with the limited information initially given?

Please explain as thoroughly as possible. Thank you!!

F(X) = X^3-5X^2-11X+11

my teacher said it was factorable, but I'm stumped.

1) f(x) = -2x^2 + 6x + 2

2) f(x) = (2/3)x^2 + (4/3)x -1

My Sony HX200V doesn't have bulb mode. :(

Please go step by step on how to do the problem.

Find arithmetic sequence equation when a3=4 and a8=14

Is the answer [2(x^2+x+10)] / [(x+3)(x-5)]

or 2(x^2+x+10)?

or another answer?

I already took regular Chem, is the test too hard for those who have not taken AP Chem?

A mother makes a list of 5 gift ideas for Mother's Day and gives the list to each of her 5 children. If each child buys on gift on the list at random, what is the probability that at least two gifts are the same?

Please explain as thoroughly as possible! Thank you!

The problem is:

You toss a coin three times. Find the probability of the given event.

a) You toss EXACTLY one tail.

b) You toss AT LEAST one tail.

Would both the questions have different answers since it looks like it's worded differently?

Could you answer the questions?

You have time to see at most 3 movies at a theatre showing 8 movies. In how many ways can you choose the movies?

Okay, my question about the problem is, when you try to solve this problem, why you have 8C3 + 8C2 + 8C1 + 8C0? Why not just 8C3?

Also explain for these problems:

Six cards are drawn for a standard deck of playing cards (52 cards total). Find the number of ways to get exactly three pairs of any three different types of cards (for example, 2 sevens, 2 fives, 2 queens)

13C1 x 4C2 x 12C1 x 4C2 x 11C1 x 4C2 (this one is the same concept, but instead of adding, there is multiplication, but why? )

and

A pizza comes with a choice of 6 different toppings. You have decided that you must have at least 5 of these toppings. In how many ways can you choose these toppings?

6C5 + 6C6

5 cards are drawn from a standard deck (52 cards total). In how many ways can you choose 3 hearts and 2 diamonds? (13 hearts, 13 diamonds in a deck)

Please explain thoroughly how to get the answer! Thank you!

I don't understand how you find "p" when you're trying to graph parabolas.

For example, if the equation is y=(1/8)x^2, you do (1/4)p =(1/8), and somehow p is supposed to equal 2. But why??

Also, y^2= -12x, (1/4)p=1/12, and somehow p=3...

Can you please explain why? Thanks
