Abotanist is using two types of plants for an experiment. she writes inequalities to model the constraints on the number of each type of plant she can use. she uses linear programming to find the vertex of the feasible region that results in the minimum value, in dollars, of the cost function. if that vertex is (5, 39), what do the coordinates represent? a. buying five of one type of plant and 39 of the other type of plant results in the lowest cost.

b. buying five of each type of plant costs $39, which is the lowest possible cost.

c. the lowest possible cost of the plants is $5, which occurs when 39 of each type of plant are bought.

d. the lowest possible cost of the plants is $5, which occurs when a total of 39 plants are bought.

The answer is: A. Buying five of one type of plant and 39 of the other type of plant results in the lowest cost.

Explanation:

Linear programming studies the situations in which it is required to maximize or minimize functions that are subject to certain limitations.

All the elements are searched, in this case the two types of plants (a, b), for which the function takes the smallest possible value, in this case the cost.

The answer is: A. Buying five of one type of plant and 39 of the other type of plant results in the lowest cost.

plant because they survive by water, sunlight, ex.

explanation:

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
