Answer:
this is correct
Step-by-step explanation:
f continous in x=30 means that it should be the same value for 1.25 x 30 and 1.10 x 30 + k so k =4.5
Answer:
Step-by-step explanation:
JT = 19. 3(4) + 7
37 = CJ + JT
37 = 3x + 6 + 3x + 7
37 = 6x + 13
24 = 6x
X = 4
Cos (A-B) - cos (A+B)
= (cosAcosB +sinAsinB) - (cosAcosB - sinAsinB)
=2sinAsinB
Ans: 4
