The price of a certain item changes over time, the equation y=4.78x^2 + 271.26x-841.52 models the total y dollars of profit a company makes in one day on the item when the price of the item that day is x dollars. what is the approximate profit the company makes on the item on a day when the item price is $23

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
