What are all solutions to the differential equation dy/dx=sec^2*x ?

zysi [14]

Answer:

y=tanx+C

Step-by-step explanation:

$\frac{dy}{dx} = {sec}^{2} \: x \\ \\ dy = {sec}^{2} \: x \: dx \\ integrating \: both \: sides \\ \\ \int \:1\: dy = \int {sec}^{2} \: x \: dx \\ \\ \huge \red{ \boxed{ \therefore \: y = tan \: x + c}} \\$

The police uses a speed gun to monitor one part of the highway. During one hour, 6 out of 25 cars were traveling above the speed

Oksanka [162]

24% of the cars were travelling above the speed limit.

Step-by-step explanation:

Given,

Total cars monitored = 25

Cars traveling above the speed limit = 6

Percent of cars traveling above speed limit = $\frac{Cars\ travelling\ above\ speed\ limit}{Total\ cars\ monitored}*100$

Percent of cars = $\frac{6}{25}*100\\$

$Percent\ of\ cars=\frac{600}{25}\\Percent\ of\ cars=24\%$

24% of the cars were travelling above the speed limit.
