Step 1:
a) Write the quadratic model
a = -15.64
b = -1.24
c = 5.23
b) t = 0.30
c) t = 0.52 seconds
d) 0.30 is more likely to be relaible.
e)
Fractions are just unsimplified numbers. For example 5/8 is just 5 divided by 8 so 0.625. To find the percent from that you move the decimal two places to the right making it 62.5%. Hope this helps!
Group together the like terms (plus 2x with 2x) (subtract 10 by 6)
4x+4=36
Move plus four to the other side as a negative
4x=32
Divide both sides by 4
32 divided by 4 is 8
Therefore, x is equal to 8
Answer:
d. 15.3%
