Answer:

Option b is correct.

Step-by-step explanation:

From the given condition : Seven less than the quotient of a number, x, and twelve is five times the number.

Here, the number is x

The quotient of a number x and twelve is expressed as ,  \frac{x}{12}

Seven less than the quotient of a number, x, and twelve is expressed as,  \frac{x}{12}-7

Five times the number mean, 5x

Therefore, we have an equation in the form of <em>x</em>  from the given condition as:

\frac{x}{12}-7=5x .

Consider a civilization broadcasting a signal with a power of 2.0×104 watts. The Arecibo radio telescope, which is about 300 met
Vitek1552 [10]

For light: Inverse Square Law 

<span>
The signal is weaken by the inverse square of the difference of distances this means that one over the square of the difference. </span>

<span>
</span>

Therefore, 70000LY / 141 LY =496.45 and that squared =246462.602 times less signal, or 1/246462.602.


 2 For a circular telescope like the Arecibo radio telescope that equals Pi times the radius squared. Sensitivity of the telescope depends on its area.<span>
The new telescope needs 246462.60 times that area to have enough sensitivity </span>

<span>
<span>(150 x 150 x Pi) = 70 685 sq m area for the Arecibo telescope and that times 246462.60
= 1.74212 x 10^10</span></span>

<span><span>
</span></span>

What is the diameter of a circle with that area?

 <span>
<span>1. Divide the area by Pi = 5.548156 x 10^9
2. Take the square root of the result to find the radius = 74485.94293</span></span>

3. Multiply by 2 to find the diameter = <span>148971.886</span>

How many different solutions are there to the equation (x² - 4x + 5 )ˣ²⁺ˣ⁻³⁰=1
Anna71 [15]

A power a^b gives 1 as a result in two cases

  1. The base is 1, and every exponent is good: 1^b=1 \forall b
  2. The exponent is 0, and every non-zero base is good: a^0=1 \forall a\neq 0

So, we need either

x^2-4x+5=1

or

x^2+x^{-30}=0

The first happens if

x^2-4x+5=1 \iff x^2-4x+4=0 \iff (x-2)^2=0 \iff x=2

The second happens if

x^2+x^{-30}=0 \iff \dfrac{1+x^{32}}{x^{30}}=0

which is impossible.

So, the only solution is x=2
