 5/4=y−1/4<br><br>y=_____<br>What is the answer?
Nat2105 [25]

In this equation, you are solving for y. Simply isolate the variable by adding 1/4 to each side. The -1/4 and 1/4 will cancel out on the right side of the equation, leaving only y:


5/4 = y - 1/4


5/4 + 1/4 = y - 1/4 + 1/4


6/4 = y


y = 6/4


Don't forget to simplify y:


y = 3/2

Kimberly makes a conjecture that the sum of two odd integers is always an even integer. Which choice is the best proof of her co
Gala2k [10]

Answer:

third choice : Let 2a + 1 be one odd number, and let 2b + 1 be the other odd number. (2a + 1) + (2b + 1) = 2a + 2b + 2 = 2(a + b + 1). Because 2(a + b + 1) is evenly divisible by 2, it is an even number.

You’re welcome ;)

Use demoivre's theorem to show that;<br>cos4¤ =8 cos4¤ -8cos2¤+1​
ss7ja [257]

Answer:

\cos4( \theta)=Re(\cos4( \theta)+i\sin4( \theta)) \\=Re(\cos ( \theta)+i\sin ( \theta))^4 \\  =Re(cos^4( \theta)+4cos^3( \theta)isin( \theta)+6cos^2( \theta)i^2sin^2( \theta)+4cosi^3( \theta)sin^3( \theta)+i^4sin^4( \theta)) \\cos( 4\theta) =cos^4( \theta)-6cos^2( \theta)sin^2( \theta)+sin^4( \theta) \\ =(1-\sin^2( \theta))^2-6(1-\sin^2( \theta))\sin^2( \theta)+sin^4( \theta) \\ =  1-2\sin^2( \theta)+\sin^4( \theta)-6\sin^2( \theta)+6\sin^4( \theta)+\sin^4( \theta) \\ =8\sin^4( \theta)-8\sin^2( \theta)+1

Find the mass of a thin triangular plate bounded by the coordinate axes and the line if
sergij07 [2.7K]

The mass of a thin triangular plate bounded by the coordinate axes is 3 3/4.

<h3>How to calculate the mass?</h3>

It should be noted that mass simply means a quantity of matter that's in a body. It's the meaure of the inertia in the body.

In this case, from the complete question, the mass will be:

= 3/1000[1/24x⁴ - 25x² + 1000/3x]

= 15/4

= 3 3/4
