You want to buy a pet lizard that costs $45. You already have $14 and you plan to save $7 per week. If w represents the numbe
r of weeks until you have enough money to buy the , what equation could you use to find the value of w? Explain how you could set up an equation to find the amount of money you should save each week if you want to buy the lizard in 3 weeks.
Y = sin x + sin² x y ` = f ` ( x ) = cos x + 2 sin x cos x f `( 0 ) = cos 0 + 2 sin 0 cos 0 = 1 The tangent line formula: y - y0 = f ` ( x0 ) ( x - x0 ) y - 0 = 1 · ( x - 0 ) Answer: y = x
