Step-by-step explanation:
Answer:
1126
Step-by-step explanation:
<u>Given formula</u>:

Given information:
Substitute these values into the formula and solve for k:

Substitute the found value of k into the formula:

If:
- P₁ = Population on March 1st 2016
- P₂ = Population on March 1st 2017
Then:
- P₃ = Population on March 1st 2018
- P₄ = Population on March 1st 2019
Use the formula and the value of P₂ to find P₃ and P₄.


Therefore, the prediction for the population on 1st March 2019 is 1126 tadpoles (nearest whole number).

Step-by-step explanation:
Answer:
straight line through (0,4) and (2,0), shade everything above it
Step-by-step explanation:
First solve the equality, which will give you a straight line.
Then check if the inequality (the > sign) means you have to shade the area above or below it.
2x + y = 4 can easily be solved by first taking x=0, then you find y=4, hence (0,4) is a solution.
Then take y=0, then you find 2x = 4 so x=2, hence (2,0) is a solution.
Plot these two points and draw a line through them.
Now, since 2x+y has to be larger than 4, all the points to the right and above the line are valid. So that's the area you have to shade.
