Answer:
1 seconds after being thrown, the stone reaches its max height
Step-by-step explanation:
The parabolic (quadratic) equation is:

Lets expand this in the form
, so we have:

We can say the values of a,b, and c, now to be:
a = -5
b = 10
c = 40
The number of seconds at which the max would occur is given by the point, x, at:

We know a and b, let's find the seconds, x,

Hence,
1 seconds after being thrown, the stone reach its max height
Answer:
E would most likely stand for exponent
Step-by-step explanation:
Lets say we have a rectangle. if the ratio is 7:5, we can put the width as 7x, and the length as 5x (or vice versa, it doesn't really matter.) If the perimeter is solved by 2(h+w), we have 2(7x+5x)=96, or 2(7x)+2(5x)=96, which is C
6/40 6.0/40.0 because it’s decimal and percentage wiser
Answer: C, a woman whose father was a United States citizen
Step-by-step explanation: Your siblings do not affect your citizenship, so A is incorrect.
As for B, you need to go through a ton of legal stuff to become a citizen if you are born in a different country. D is incorrect because it legit makes zero sense. If you're from a country the US dislikes, it'll be even harder to become a citizen
