B because 12-14 is equal to -2.
Answer:
The answer to your question is:
a) P(3) = 5818 mosquitoes
b) 4 days
Step-by-step explanation:
Data
P(t) = Poekt
a)
Po = 1000 mosquitoes
Pt = 1800
t = 1 day
P(3) = ?
1800 = 1000 e1k
1800 / 1000 = e 1k
e 1k = 1.8
1k = In 1.8
k = 0.587
P(3) = 1000 e (0.587)(3)
P (3) = 1000 e 1.761
P(3) = 5818. 2 mosquitoes
b)
P(t) = 10,000
10000 = 1000 e 0.587t
10000 / 1000 = e 0.587t
10 = e 0.587t
In 10 = in e 0.587t
2.3 = 0.587t
t = 3.92 days ≈ 4 days
Do you mean the circumference? You can’t find the perimeter of a circle. The circumstance of the circle is 39.584 to 3dp.
Answer:
-2.5 I THINK
Step-by-step explanation:
First off we have x number of students in the robotics club, 12 more in the Science club, and 84 students in total. This means:
Robotics Club = x
Science Club = (x + 12)
Total = 84
Okay, so here's the equation:
x + (x + 12) = 84 ~ Add like terms.
2x + 12 = 84 ~ Subtract 12 by both sides.
2x = 72 ~ Divide both sides by 2.
x = 36 ~ Meaning that the Robotics Club has 36 members.
At this point you can do: 84 - 36 = 48 which gives you the number of members in the Science Club, though...:
36 + (36 + 12) = 84 ~ Add the two in the parenthesis to get your answer.
36 + 48 = 84 ~ 48 is the number of Students in the Science Club.
84 = 84
In conclusion: The Science Club has 48 students.
Hope that helps. ^ ^
