Factor completely 36x^2 − 25.

sveticcg [70]

Hello there!

$( (2^2*3^2x^2) - 25) \\ \\ Factoring: \boxed{36x2-25} \\ \\ (PROOF): \\ \\ (A+B) * (A-B) = \\
 A2 - AB + BA - B2 = \\
 A2 - AB + AB - B2 = \\
 A2 - B2 \\ \\$

Your final answer would be ( (6x + 5) • (6x - 5)).

Your correct answer would be (option d).

I hope this helps you!

Two boats sail away from a buoy making a 90 degree angle. The first boat is 165 meters away and is traveling at 25 m/s. The seco

NikAS [45]

Answer:

Step-by-step explanation:

lets say in the shown triangle x=165

so speed $\frac{dx}{dt} =25$

and $\frac{dy}{dt} =35$

Also since distance = speed* time

time = pi minutes = pi/60 seconds

y = $\frac{35\pi \pi }{60}$

y = $\frac{7\pi }{12}$

Now using the pythagorean :

$x^2+y^2=z^2\\so \\165^2+(\frac{7\pi }{12} )^2 =z^2$

derivate the equation so we get :

$x\frac{dx}{dt} +y\frac{dy}{dt} =z\frac{dz}{dt} \\$ $165*25+35*\frac{7\pi }{12}=\sqrt{165^2+(\frac{7\pi }{12})^2} *\frac{dz}{dt}$

$\frac{dz}{dt} =25.387$ m/s

So Rate of change = 25.387 m/s
