Answer:
D. It is the product of the initial amount and the decay factor after w weeks.
Step-by-step explanation:
We are told that Ariana starts with 100 milligrams of the substance. The number 100 in the expression likely represents this amount, <em>the initial amount</em>. It is multiplied by another number, so is part of a product. (It is not part of a difference, and is not something that is raised to a power.)
The factor (1 -0.2) represents the fraction remaining at the end of a week. That number raised to the power w will represent the fraction remaining at the end of w weeks. This fraction can reasonably be referred to as "the decay factor after w weeks."
Hence, the expression represents ...
<em>the product of the initial amount and the decay factor after w weeks</em>
The answer is A because it has 4 sides
Answer:
∠PQL=∠TRN [Corresponding angles]
So, PQ║RS and PQ=RS
Step-by-step explanation:
Side PQ is drawn.
Another side QR is drawn making an acute angle with side PQ.
Now side QR is extended towards left.
Draw an arc from point Q such that it cuts QP at M and RQ produced at L. Without changing the compass width i.e distance between nib and pencil draw an arc from point R such it cuts RQ at N.Now measure the Distance LM using compass.Place the compass at N and cut an arc that you have drawn from point R.Mark this pont as T.Draw a line passing from R and T .Then measure the length of PQ using compass.Put your compass at R and cut an arc on the line RT produced at S.Then the line PQ ║RS and PQ =RS.
Why this happens because
∠ MQL=∠NRT [ corresponding angles taking QR as Transversal]
∵PQ║RS and PQ=RS [PQRS is a parallelogrm]
