According to the Encyclopedia Britannica, "The snowy tree cricket (Oecanthus fultoni) is popularly known as the thermometer cricket because the approximate temperature (Fahrenheit) can be estimated by counting the number of chirps in 15 seconds and adding 40." Express this statement as a formula giving the temperature T as a function of the number N of chirps per 15 seconds for the snowy tree cricket.

Algebraically, transform the expression from part (a) into an equivalent one giving the temperature T as a function of the number of chirps, R, per minute for the snowy tree cricket.

  a) T = N +40

  b) T = R/4 +40

Step-by-step explanation:

a) The problem statement tells us ...

  temperature = (chirps in 15 seconds) + 40

  T = N +40 . . . . . using assigned variables.

__

b) There are 60 seconds in 1 minute, so 60/15 = 4 times as many chirps as in 15 seconds. Then the number of chirps (N) in 15 seconds will be R/4, where R is chirps per minute.

Substituting for N in the above equation gives ...

  T = R/4+40

step-by-step explanation:

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
