Answer:
Step-by-step explanation:
We know that the general form of the exponential decay formula is
, where y is final amount remaining after t time, A is the original amount and r is the rate of decay
Now, the ratio of strontium-90 remaining, p , as a function of years, t , since the nuclear accident.
Hence, the ratio of remaining since the nuclear accident is
Answer:
Step-by-step explanation:
Hello,
To know the height of the baseball when it is hit we have to compute h(0), as t = 0 is when the baseball is hit into the air.
So, the answer is <u>2 feet.</u>
<u />
h(x) is a parabola which can be written as , it means that the vertex is the point (-b/2a,h(-b/2a)).
The baseball reached its maximum height after
And the maximum height of the baseball is h(4).
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
