Answer:

(2 - π) / 4

Step-by-step explanation:

cos⁻¹(- √3 /2)) = cos⁻¹ (-0.866) = 150°

sin 150° = 0.5 = 1/2

sin (- π /2) = -1

tan (sin (- π /2)) = tan (-1) = - 45° = - π / 4

1/2 + (- π /4) = (2 - π) / 4

Complete the table so that the cost per banana remains the same.
Aneli [31]

Step-by-step explanation:

No. of banana    Cost      Unit price

4                            2            0.50

6                            3             0.50

7                           3.5           0.50

20                         10            0.50

20                          10             0.50

33                          16.50        0.50

Cost = No of banana x unit price

Cost = 4 x 0.50 = 2

Cost = 6 x 0.50 = 3

Cost = 7 x 0.50 = 3.50

Cost = 20 x 0.50 = 10

No of banana = Cost / Unit price

No of banana = 10 / 0.50 = 20

No of banana = 16.50 / 0.50 = 33
