Answer:
21x²
Step-by-step explanation:
hopefully A is a typo
Answer:
81, tens place is 8 ,unit's pkace is 1, so 8>1, that satisfies.
500 because you would round down because it is less than 5.
Answer:
(D) "...because he will not have to pay any interest on his purchases during the introductory APR period."
Step-by-step explanation:
There may be many reasons for John to choose one over the other depending on his future and planned usage patterns. However, answer the (D) is the only correct one in terms of stating a reason that is actually supported by the information in the question. Specifically, there is 0% APR for card B.
What's wrong with the other choices:
Choice A: incorrect statement re APR after intro period (is not 1%); B: incorrect statement re cash advance (is not 0%); C: statement is not supported by anything in the information given (it is an assumption, and is unlikely).
<u>Part A</u>
<u />
So, the x-intercepts are
<u>Part B</u>
The vertex will be a minimum because the coefficient of is positive.
The x-coordinate of the vertex is
Substituting this back into the function, we get
So, the coordinates of the vertex are
<u>Part C</u>
Plot the vertex and the x-intercepts and draw a parabola that passes through these three points.
The graph is shown in the attached image.
