Answer:
2.5mg
Step-by-step explanation:
Since the half-life for the radioactive material is 3 hours, Therefore it will undergone two times of half-life process.
The first 3 hours 10mg will be decreased into 5mg. The final 3 hrs, it will decreased from 5mg to 2.5mg
Step-by-step explanation:
It is given that, Katie walks 2 ft forward and 5 ft backwards. We need to find her displacement traveled.
The difference between final position and the initial position is equal to displacement. It is the shorted path covered.
Let forward is +x and backward is -x
Initial position of Katie = +2 ft
Final position of Katie = -5 ft
Displacement = final position - initial position
= -5 - 2
Displacement = -7 ft
So, her displacement is 7 feet in backward direction.
Answer:
, x = $6
Step-by-step explanation:
The expression 
to represent the store's weekly profit in dollars, where x represents the price of a new video game.
Let 
We need to rewrite this quadratic function in the vertex form.
The equivalent expression that reveals the video game price that produces the highest weekly profit is
and the price is $6
-1.1,-0.8,-0.7,0.1,0.9,2.5
