Answer:
0.61 or 8.79
Step-by-step explanation:
h = 47t − 5t²
27 = 47t − 5t²
5t² − 47t + 27 = 0
Quadratic formula:
t = [ -b ± √(b² − 4ac) ] / 2a
t = [ -(-47) ± √((-47)² − 4(5)(27)) ] / 2(5)
t = (47 ± √1669) / 10
t ≈ 0.61 or 8.79
Answer:
25/9
Step-by-step explanation:
x^2 + 10/3 x
Take half of the x-term coefficient and square it.
1/2 * 10/3 = 10/6 = 5/3
(5/3)^3 = 25/9
Answer: 25/9
