Step-by-step explanation: The leg is the smallest number and the hypothenuse is the biggest nunber.
0=40-10t-5t^2
t^2+2t-8=0
(t+4)(t-2)=0
t=-4 (not a solution) or t=2
Answer: after 2 seconds
Step-by-step explanation:
Let X = the number of days.
For growth rate,
y = X° × rate of growth, k
Where,
X° = initial amount of bacteria
k = rate of growth per day
Colby = 50 bacteria
kc = 2^(24/2 × X)
y = 50 × 2^(12X)
Jaquan = 80 bacteria
kj = 2^(24/3 × X)
y = 80 × 2^(8X)
1/4
Your teacher wrote it wrong. 1/86 should be 1/36. The pattern is dividing the denominator by 3.
