If the surface area of the box in the diagram is 204.25 square feet, what is the value of ‘x’?

Alexandra [31]

Note: Consider x be the breadth of the box.

Given:

The surface area of the box is 204.25 square feet.

Length of the box = 10 ft

Breadth of the box = x ft

Height of the box = 6.5 ft

To find:

The value of x.

Solution:

The surface area of a cuboid is:

$SA=2(lb+bh+hl)$

Where, l is length, b is breadth and h is height of the cuboid.

Putting $SA=204.25, l=10,\ b=x,\ h=6.5$ in the above formula, we get

$204.25=2(10\times x+x\times 6.5+6.5\times 10)$

$204.25=2(10x+6.5x+65)$

$204.25=2(16.5x+65)$

Using distributive property, we get

$204.25=2(16.5x)+2(65)$

$204.25=33x+130$

$204.25-130=33x$

$74.25=33x$

Divide both sides by 33.

$\dfrac{74.25}{33}=x$

$2.25=x$

Therefore, the correct option is B.

4> Solve by using Laplace transform: y'+5y'+4y=0; y(0)=3 y'(o)=o

harina [27]

Answer:

$y=3e^{-4t}$

Step-by-step explanation:

$y''+5y'+4y=0$

Applying the Laplace transform:

$\mathcal{L}[y'']+5\mathcal{L}[y']+4\mathcal{L}[y']=0$

With the formulas:

$\mathcal{L}[y'']=s^2\mathcal{L}[y]-y(0)s-y'(0)$

$\mathcal{L}[y']=s\mathcal{L}[y]-y(0)$

$\mathcal{L}[x]=L$

$s^2L-3s+5sL-3+4L=0$

Solving for $L$

$L(s^2+5s+4)=3s+3$

$L=\frac{3s+3}{s^2+5s+4}$

$L=\frac{3(s+1)}{(s+1)(s+4)}$

$L=\frac3{s+4}$

Apply the inverse Laplace transform with this formula:

$\mathcal{L}^{-1}[\frac1{s-a}]=e^{at}$

$y=3\mathcal{L}^{-1}[\frac1{s+4}]=3e^{-4t}$
