Answer:
The price for 3.75 pounds of cherries is $17.775.
Step-by-step explanation:
The price las week was $ 4.99 and it got a discount of 15% for this week, this means that the price for this week is 100% of the one prior minus 15%, therefore it is 85% of the last price. We need to calculate the price per pound with this discount as shown below:
Since the price is $4.74 per pound and we want to buy 3.75 pounds, then the total amount we need to pay is:
The price for 3.75 pounds of cherries is $17.775.
Answer:
a) The location of the turning point is approximately .
b) Roots are approximately and
.
c)
Step-by-step explanation:
a) The figure presents the graphic of a parabola, that is, a second order polynomial, with an absolute minimum (vertex). The turning point of the graphic, that is, the point in which behavior of the curve changes, is the vertex. Hence, the location of the turning point is approximately
b) According to the Quadratic Formula, second-order polynomials can have either two real roots or two conjugated complex roots. In this case, we have two real roots. A root corresponds with the point of the curve that passes through x-axis. In this case, roots are approximately and
.
c) is the function evaluated at
, that is, the value on y-axis associated with
. Lastly, we conclude that
.
