Step-by-step explanation:
b Base 8in
hb Height 3in
A=hbb
2=3·8
2=12in²
220. Think of it this way: 5 and above, give it a shove, 4 and below, keep it down low. That means that if the last number is five or above, push it up to the nearest 10, and if the last number is four or below, round to the lowest 10.
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
