Add 7 to both sides : -6 = v
The answer exactly is 93.5% because 58 over 62 is 0.935 then multiply it by 100 and there's your answer!
Answer:
The common for the second question is 30
Answer:
A
Step-by-step explanation:
The position of an atom moving inside a cathode ray tube is given by the function:

Where f(t) is in meters and <em>t</em> is in seconds.
And we want to determine its instantaneous velocity at <em>t</em> = 2.5 seconds.
The velocity function is the derivative of the position function. Thus, find the derivative of the function:
<em />
<em />
<em />
Then the instantaneous velocity at <em>t</em> = 2.5 will be:

Our answer is A.
