Write 2, 330, 000 in scientific notation?

Genrish500 [490]

Answer:

2.33 × 10^6

Step-by-step explanation:

I just used a calculator, to be honest. It was super simple.

2.33 * 10^6

2.33 * (10*10*10*10*10*10)

which then equals 2,330,000

Help on this problem?? please?

Answer to #4: 81/256 * s^8 * t^ 12

Comments:

(7x^3) ^ (1/2) = 7 ^ (1/2) * x^(3/2) where ^(1/2) means the square root of a quantity. The answer written (7x^3) is NOT correct.

---------------------

(1) (27s^7t^11)^ (4/3)

= 27^(4/3) * (s^7)^(4/3) * (t^11)^ (4/3)

As 27 = 3^3, 27 ^(4/3) = 3^4 = 81

(2) (-64st^2)^ (4/3) = (-64)^(4/3) * (s^4/3) * t(^8/3)

As 64 = (-4)^3, (-64)^(4/3) = (-4)^4 = +256

So (1)/(2) =

81 * s^(28/3)* t^(44/3)

------------------------------- =

256 s^(4/3) * t^((8/3)

81/256 * s ^ (28/3 - 4/3) * t^(44/3 - 8/3) =

81/256 * s^(24/3) * t (36/3) =

81/256 * s^8 * t^ 12

A parallelogram has sides 10m and 12m and an angle of 45°. Find the distance between the 12m-sides.

stich3 [128]

Answer:

The distance between 12m-sides is $5\sqrt{2}m$ .

Step-by-step explanation:

It is given that the parallelogram has sides 10m and 12m and an angle of 45°.

Draw an altitude from one 12m side to another 12 m side as shown in below figure.

The opposite angles of parallelogram are same. Two angles are obtuse angles and two are acute angle.

Since angle C is acute angle therefore it must be 45 degree.

$\sin\theta=\frac{perpendicular}{hypotenuse}$

$\sin C=\frac{BE}{BC}$

$\sin(45^{\circ})=\frac{d}{10}$

$\frac{1}{\sqrt{2}}=\frac{d}{10}$

$\frac{10}{\sqrt{2}}=d$

$\frac{10}{\sqrt{2}}\times \frac{\sqrt{2}}{\sqrt{2}}=d$

$\frac{10\sqrt{2}}{2}=d$

$5\sqrt{2}=d$

Therefore the distance between 12m-sides is $5\sqrt{2}m$ .
