How do I solve 2cos(x)=2sin(2x)
Vedmedyk [2.9K]
2cosx=2sin2x. Sin2x is an identity for 2sinxcos. So 2[2sinxcosx] gives you 4sinxcosx. 2cosx=4sinxcosx. Divide 2cosx on both sides and gives you 2sinx=0 and divide again, sinx=0. Sinx is 0 at 0 and 360 degrees, or pi and 2pi. So thats what x would be. 0,360,pi,2pi.

Team tool bella canoed 15 3/4 miles in 5/4 hours. What was their average rate of speed in mph ​
luda_lava [24]

Average speed is 12.6 miles per hour

<em><u>Solution:</u></em>

Given that team tool bella canoed 15\frac{3}{4} miles in \frac{5}{4} hours

To find: average rate of speed in miles per hour

From given information,

distance = 15\frac{3}{4} \text{ miles } = \frac{15 \times 4+3}{4} = \frac{63}{4} \text{ miles}

time = \frac{5}{4} \text{ hours}

To find the speed we use the below formula,

speed = \frac{distance}{time}

Substituting the given values we get,

speed = \frac{\frac{63}{4}}{\frac{5}{4}}\\\\speed = \frac{63}{4} \times \frac{4}{5} = \frac{63}{5} = 12.6

Thus average speed is 12.6 miles per hour
