Answer:

Saturn’s orbital period is 29.6 years

Step-by-step explanation:

It is given that,

The mass of the sun, m = 1.99 × 10³⁰ kg

Saturn orbits the sun at a distance of, a = 1.43 × 10¹² m

Using third law of Kepler's :

T^2=\dfrac{4\pi^2}{GM}a^3

Where,

T is the orbital time period

G is the universal gravitational constant

M is the mass of the sun

a is the distance

So, T^2=\dfrac{4(3.14)^2}{6.67\times 10^{-11}\times 1.99\times 10^{30}}(1.43\times 10^{12})^3

T=\sqrt{8.688\times 10^{17}}\ s

T=932094415.818\ s

To convert seconds into year divide the time by 3.154 × 10⁷

So, T = 29.55 Years

or T = 29.6 Years

Hence, the Saturn's orbital period is 29.6 Earth years

The simplest form of the expression -2x2(x – 5) + x(2x2 – 10x) + x is
Bad White [126]
For this case you must simplify the expression respecting the rules of multiplication of mathematics.
 The steps to simplify the expression are the following:
 First multiply what is in the parentheses
  -2x ^ 2 (x - 5) + x (2x ^ 2 - 10x) + x
  -2x ^ 3 + 10x ^ 2 + 2x ^ 3 - 10x ^ 2 + x
 Then add the terms that have the same exponent
 (-2x ^ 3 + 2x ^ 3) + (10x ^ 2 - 10x ^ 2) + x
  x
 The final simplification is

Find the value of y in the given triangle
Andre45 [30]

Given:

In the given triangle,

With respect to y, Perpendicular = 10 cm and Base = 8 cm

To find the value of y.

Formula

By Trigonometric Ratio we get,

tan\theta = \frac{Perpendicular}{Base}

Now,

Putting the values of perpendicular and base we get,

tan\theta = \frac{10}{8}

or, \theta = tan^{-1} (\frac{10}{8})

or, \theta = 51.34 ^\circ

Rounding off to the nearest tenth, we have;

\theta = 51.3 ^\circ

Hence,

The value of y is 51.3°.

Multiply out and simplify to obtain a minimum sum-of-products boolean expression:
max2010maxim [7]

Answer:

As per the question, we need to convert product of sum into sum of product,

Given:

(A' +B+C')(A'+C'+D)(B'+D'),

At first, we will solve to parenthesis,

= (A'+C'+BD) (B'+D')

As per the Rule, (A+B)(A+C) = A+BC, In our case if we assume X = A'+C', then,

(A' +B+C')(A'+C'+D) = (A'+C'+B)(A'+C'+D) = (A'+C'+BD)

Now,  

= (A'+C'+BD) (B'+D') = A'B' + A'D' + C'B' +C'D' +BDB' +BDD"

As we know that AA' =  0, it mean

=A'B'+A'D'+C'B'+C'D'+D*0+B0

=A'B'+A'D'+C'B'+C'D'               as B * 0 and D*0 = 0

Finally, minimum sum of product boolean expression is

A''B'+A'D'+C'B'+C'D'

=
