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

- Given - <u>a </u><u>bus </u><u>takes </u><u>6</u><u> </u><u>hours</u><u> </u><u>to </u><u>travel </u><u>a </u><u>particular</u><u> </u><u>distance </u><u>with </u><u>a </u><u>constant</u><u> </u><u>speed </u><u>of </u><u>3</u><u>6</u><u> </u><u>km/</u><u>hr</u>
- To calculate - <u>the </u><u>total </u><u>distance </u><u>travel </u><u>by </u><u>the </u><u>bus</u>
We know that ,

2800 + 3200 + 3600 = 9600kWh
9600kWh divided by three is the average energy usage per month
3200kWh
3200kWh times by 3 cents is the average cost per month in cents
9600 cents
divided by 100 is the price in dollars

Answer: Rs7500
Step-by-step explanation:
First and foremost, we should realise that a square has 4 sides. Therefore, the total sides of the square will be:
= 125m × 4
= 500m
Since the rate is Rs15 per meter, then the cost of the fencing will be:
= 500 × Rs15
= Rs7500
