Examples - Measurements in cooking; Metric measurements (7 1/4”); Distance (9 1/2 miles)
Real-World Problem - You’re baking and need to triple a recipe. The recipe calls for 3 3/4 cups flour (per recipe). You’d need to triple that amount to make how much you’re looking to make. (3 x 3 3/4 = 11 1/4 cups flour)
2 - 125x = 0,5x - 5
-125x - 0,5x = -5 -2
-125,5x=-7
x= -7/-125,5
x=0,05...
Answer:
sin⁴x - sin²x
sin²x(sin²x - 1)
(1 - cos²x)(1 - cos²x - 1)
(1 - cos²x)(-cos²x)
-cos²x + cos⁴x
cos⁴x - cos²x
