Answer:

Step-by-step explanation:

$\frac{(3x^{2} )^\frac{1}{2} }{3^\frac{1}{2} } =3$

$(3x^2)^\frac{1}{2} = 3^\frac{1}{2} x$

Remember that $\frac{x^b}{x^c} =$ x^(b-c)

Using that $\frac{3^\frac{1}{2}x }{3^\frac{1}{2} }$ =3^(1/2x-1/2)=3^((x-1)/2)

$3^\frac{x-1}{2} =3^1$

So we can say: $\frac{x-1}{2} =1$ , because the bases are the same

We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.

antiseptic1488 [7]

Answer:

Hence the correct answer is option (A) 4.708.

Step-by-step explanation:

Solution:-

Now, we need to find the angle of the sector by using sector formula,

$A = 28.25 ft^{2} \\r = 12ft.\\\\28.25 = \frac{\theta}{360^{o} } \times \pi \times 12^{2} \\\\\theta=\frac{28.25\times 360}{12 \times12 \times \pi} \\\\\theta =( \frac{70.625}{\\pi} )^{o}$

We now convert the angle to radian

$\theta = \frac{70.625}{\pi} \times \frac{\pi}{180}\\\\\theta = 0.39236 radian$

Now we calculate the length of arc by arc formula

$\theta=\frac{I}{12} \\\\0.39236 =\frac{I}{12}\\\\I = 4.708 feet.$

So, The length of steel that must be replaced is 4.708 ft.

Answer:

356.53

Step-by-step explanation:

Calculate the semicircle and square areas separately. For the semicircle, A = πr²/2, so 100.53

And for the square, A = a², so 256

The distance from earth to the moon is about 22^4 miles.The distance from earth to neptune is about 22^7 miles.Which distance is

fiasKO [112]

You are NOT using scientific notation correctly. When you say 22^4 you are saying 22*22*22*22 which equals 234,256. What you should say is Earth to Moon distance = 22 * 10^4 miles. (To be really precise, it should be expressed as 2.2 * 10^5 miles).

Earth to Neptune distance = 2.2 * 10^8 miles.

2.2 * 10^8 / 2.2 * 10^5 = 1,000. So the Earth to Neptune distance is 1,000 times greater than the Earth to Moon distance.
