Answer:
<em>4.52secs</em>
Step-by-step explanation:
Given the height of a falling object expressed as;
d=3t+5t^2
If the object travel 84 feet, we are to find the time t it takes to travel. On substituting;
84 = 3t+5t^2
3t+5t^2 - 84 = 0
t = -5±√25-4(3)(-84)/2(3)
t = -5±√25+1008/6
t = -5±32.14/6
t = -5+32.14/6
t = 27.14/6
<em>t = 4.52 secs</em>
<em>Hence it will take 4.52secs for the object to travel 84feet</em>

Answer: (0, -1
), (1, -1), (2, 1)
<u>Step-by-step explanation:</u>
Set the exponent equal to zero - <em>that is your anchor point</em>.
Then choose an x-value less than and greater than the anchor point.

I believe the answer is 5. Hope this was right for you.
