Ana is planning to plant roses around the edge of a circular flowerbed having a diameter of 7 feet. if the total cost of planting roses is $176, what is the unit price of planting roses per foot? (use π=227.)

9. (y^-5)^10y^10 a. y^-60 b. y^60 c. y^-150 d. y^150 find the simplified form of each expression. 10. (4/7^5)^2 a.8/14^10 b.16/49^25 c.16/49y^10 d.8/14y^25 11. determine if the number 3.43 times 10^-6 is written in scientific notation. if not, explain. a. yes; the number is written scientific notation. b. no; the first factor is not a number between 1 and 10. c. no; it is not written as a number times a power of 10

If eh = hg and hg=16, find the diameter of k

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
