The flow of blood in a blood vessel is faster toward the center of the vessel and slower toward the outside. The speed of the blood​ V, in millimeters per second​ (mm/sec), is given by the following​ formula, where R is the radius of the blood​ vessel, r is the distance of the blood from the center of the​ vessel, and​ p, L, and v are physical constants related to​ pressure, length, and viscosity of the blood​ vessels, respectively. Assume that r is a constant as well as​ p, L, and v. Complete parts​ (a) and​ (b) below. V=p/4Lv(R^2-r^2)

How many solutions does the nonlinear system of equations graphed bellow have?

Samantha is growing a garden in her back yard. she spend $90 setting up the garden bed and buying the proper garden supplies. in addition, each seed she plants cost $0.25. a. write the function f(x) that represents samantha's total cost on her garden. b. explain what x represents. c. explain what f(x) represents. d. if samantha plants 55 seeds, how much did she spend in total?

Which situation could best be represented by this linear equation? 24x + 38y = 520 > if x represents the number of bracelets and y represents the number of rings, there were 24 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets and y represents the number of rings, there were 38 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets sold at $24 each and y represents the number of rings sold at $38 each, the total sales were $520 if x represents the number of bracelets and y represents the number of rings, there were 520 bracelets and rings sold. bracelets were $24, and rings were $38. e
