The height h above ground in feet of a ball dropped from the top of a 30 foot tall building after t seconds is given by the polynomial: h(t)= -16t^2+30. what is the height of the ball after 1/2 second?
h(t)= -16t^2+30

Sub 1/2 for t to find h(1/2)
In the metric system, you give a name to the following multiples: 10, 100, 1000, 0.1, 0.01, 0.001, and then you skip three places. So, you have
![\left.\begin{array}{cc}\vdots&\vdots\\1000000&\text{mega}\\1000&\text{kilo}\\100&\text{hecto}\\10&\text{deca}\\0.1&\text{deci}\\0.01&\text{centi}\\0.001&\text{milli}\\0.000001&\text{micro}\\\vdots&\vdots\\\end{array}\right.](https://tex.z-dn.net/?f=%20%5Cleft.%5Cbegin%7Barray%7D%7Bcc%7D%5Cvdots%26%5Cvdots%5C%5C1000000%26%5Ctext%7Bmega%7D%5C%5C1000%26%5Ctext%7Bkilo%7D%5C%5C100%26%5Ctext%7Bhecto%7D%5C%5C10%26%5Ctext%7Bdeca%7D%5C%5C0.1%26%5Ctext%7Bdeci%7D%5C%5C0.01%26%5Ctext%7Bcenti%7D%5C%5C0.001%26%5Ctext%7Bmilli%7D%5C%5C0.000001%26%5Ctext%7Bmicro%7D%5C%5C%5Cvdots%26%5Cvdots%5C%5C%5Cend%7Barray%7D%5Cright.%20)
And thus 0.000001 of something is a micro-something (i.e. one millionth of a certain unit)
Let :
T = Theresa age
H = her brother
We know :
T = H - 14
T + H = 35
Substitute T
H -14 + H = 35
2H - 14 = 35
2H = 49
H = 49/2 = 24.5
Since we know H = 24.5 we then can substitute it to either equation.
T = H - 14
T = 24.5 - 14
T = 10.5
Theresa is 10.5 years old
Her brother is 24.5 years old

Answer is k>-1
Answer:
-3(a-b) < 0. divide both sides by -3 and reverse the inequality sign: 0 0
