Answer:
3 : 7
Step-by-step explanation:
make sure the three of on the left
Answer:
Y=1
Step-by-step explanation:
Plug in 3 for x
y=2(3)²-4(3)-5
y=18-12-5
y=1
Answer:
<u>Part A</u>
1. Third degree polynomial:
The function can have as many as 3 zeroes only, but it can have 4 intercepts if you include the y-intercept.
2.
Zeroes at: x = -2, x = 1 and x = 2
y-intercept at (0, 4)
End behavior:
3. see attached
<u>Part B</u>
4.
Direction: opens upwards
y-intercept: (0, 10)
zeros: x = 2, x = 5
5. see attached
**unfortunately I am unable to answer any additional questions as Brainly has a 5-question rule**
For this case we have the following equation:
y (t) = 35 * exp (3t) + 57
For 200 bacteria we have:
200 = 35 * exp (3t) + 57
Clearing t we have:
exp (3t) = (200-57) / 35
exp (3t) = 4.085714286
ln (exp (3t)) = ln (4.085714286)
3t = ln (4.085714286)
t = ln (4.085714286) / 3
t = 0.5 minutes
Answer:
the population will reach 200 bacteria at:
t = 0.5 minutes
or
t = ln (4.09) / 3
