ziro4ka [17]

Answer:

<h2>V = x³ + 54x² + 936x + 5,184</h2>

Step-by-step explanation:

<h3 /><h3>If we add a value of 'x' to each side of the box, the new dimensions can be represented as</h3><h3>x + 24</h3><h3>x + 12 and </h3><h3>x + 18</h3><h3 /><h3>To find the volume of the new box, multiply all of the dimensions together</h3><h3 /><h3>V = (x + 24)(x + 12)(x + 18)    </h3><h3> Foil the first and second binomial....</h3><h3 /><h3>V = (x² + 36x + 288)(x + 18)</h3><h3>  Now multiply the two polynomials together...</h3><h3 /><h3>V = x²(x) + 36x(x) + 288x + x²(18) + 36x(18) + 288(18)</h3><h3 /><h3>V = x³ + 36x² + 288x + 18x² + 648x + 5,184</h3><h3 /><h3>which simplifies to</h3><h3 /><h3>V = x³ + 54x² + 936x + 5,184     where x represents the increase in inches</h3>

How do I prove that (1+sinx)/cosx=cos(-x)/(1+sine(-x))
stira [4]
\dfrac{1+\sin x}{\cos x}=\dfrac{\cos (-x)}{1+\sin(-x)}\\&#10;\dfrac{1+\sin x}{\cos x}=\dfrac{\cos x}{1-\sin x}\\&#10;\cos^2 x=(1+\sin x)(1-\sin x)\\&#10;\cos^2 x=1-\sin^2 x\\&#10;\sin^2 x+\cos^2 x=1&#10;

Solve the equation for [0,2pi]<br> cos2x=1/sqrt2
lapo4ka [179]
cos(2x) = \frac{1}{\sqrt{2}}
cos(2x) = \frac{1}{\sqrt{2}} * \frac{\sqrt{2}}{\sqrt{2}}
cos(2x) = \frac{\sqrt{2}}{2}
cos(2x) = cos(45)
cos(x) = cos(22.5)
x = 22.5
