An arch has the shape of the parabola y = 36 − x2. a rectangle is fit under the arch by selecting a point (x, y) on the parabola.
(a) express the area a of the rectangle in terms of x.
(b) if x = 1, the rectangle has base 2 and height 35. find the base of a second rectangle that has the same area.

Factorize: x^2+8x+10 i just solved it but i don't know if the process is correct

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
