Lake house. harry has two houses, a house on the lake and a house in town. rebecca wants to buy the house on the lake. harry and rebecca orally agree that rebecca will buy the house on the lake for $300,000. harry hurriedly writes out a contract providing that he would sell "his house" to rebecca for $300,000. harry signs the top of the document. rebecca does not sign at all. no merger clause is included in the contract. harry backs out of the contract, and rebecca sues him. he tells the judge that the statute of frauds is left unsatisfied because he did not sign the document at the end and also because rebecca did not sign at all. then, harry also says that even if the agreement exists (i'm not saying it does or doesn't) rebecca told him he could take off $25,000 as a housewarming gift. is there an enforceable agreement? which elements of an enforceable agreement exist?

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
