Step-by-step explanation:
Answer:
6
Step-by-step explanation:
Given
3x - 15 ≥ 3 ( add 15 to both sides )
3x ≥ 18 ( divide both sides by 3 )
x ≥ 6
Since x is greater than or equal to 6 then 6 is a solution
Dy/dx= tanx, can be answered directly using the derivatives of trigonometric functions but this is how the answer is derived
=(sinx/cosx) basic trigonometric function
= [cosx cox+sinxsinx]/cos^2x
=[cos^2x+sin^2x]/cos^2x
cos^2+sin^2x = 1 ; fundamental trigonometric identities
= 1/cos^2x; reciprocal relations
= sec^2x+C
The answer is letter B.sec^2x+C
