That she needs to follow the recipe to make some good trail mix for her friends!!!!
This question is open ended and doesn't have the necessary information.
hexa means 6, so I would assume 6x5 = 30 ft, but then you want to have a side open for a 'door', so subtracting 5 would make the answer 25ft.<span />
Answer: A) 
B) H = 5.10
C) Yes
Step-by-step explanation: <u>Exponential</u> <u>Decay</u> <u>function</u> is a model that describes the reducing of an amount by a constant rate over time. Generally, it is written in the form: 
A) C is initial quantity, in this case, the initial concentration of DDT. To determine r, using the data given:



Using a natural logarithm property called <em>power rule:</em>



The decay function for concentration of DDT through the years is 
B) The value of H is calculated by 


Again, using power rule for logarithm:



H = 5.10
Constant H in the half-life formula is H=5.10
C) Using model
to determine concentration of DDT in 1995:

y(24) = 0.5
By 1995, the concentration of DDT is 0.5 ppm, so using this model is possible to reduce such amount and more of DDT.
2.3 and 2.30 both are the same but it’s in money so IDK
