This problem can be solve by graphing (technology), as suggested.
The answer is posted as an attached image. We see that after about 14.75 years, the invading species will surpass the indigenous population.
If it needs to be solved mathematically and accurately, the math is a little more advanced, using the bisection method, or Newton's method.
However, we can also do that by trial and error, starting from 14.75. It is easier than you might think.
Post if you would like to have more information on one or the other methods.
Note: the scale of y has been shrunk by 1000, so each unit on the y-axis represents 1000 frogs.
Answer:
s=5+3w independent variable is 5+3w. Dependent variable is s, since the total depends on the amount of weeks plus the 5 seashells from the start. s=5+4(3)=17 s=5+5(3)=20 s=5+6(3)=23 s=5+7(3)=26 s=5+8(3)=29 s=5+9(3)=32 s=5+10(3)=35
Step-by-step explanation:
Answer:
The first five terms in the pattern are 56, 59, 62, 65 and 68.
Step-by-step explanation:
Here, the first term in the pattern = 56
Rule : Add 9, Subtract 6
Second term :
First term + 9 - 6 = 56 + 9 - 6 = 59
Third Term :
Second term + 9 - 6 = 59 + 9 - 6 = 62
Fourth Term :
Third term + 9 - 6 = 62 + 9 - 6 = 65
Fifth Term :
Fourth term + 9 - 6 = 65 + 9 - 6 = 68
Hence, the first five terms in the pattern is 56, 59, 62, 65 and 68.
