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>
What is the square of the longest side?
80
What is the sum of the squares of the two shorter sides?
80
Is the triangle a right triangle?
Yes, the square of the longest side equals the sum of the squares of the shorter sides
Answer:
D.$4 paid for 4 hats
Step-by-step explanation:
What is unit cost?
unit cost can be defined as the amount paid for a unit quantity of a product
From the given options
only options D represents unit cost
the reason is because $4 was paid for 4 hats
it clearly shows that 1 hat cost $1
bearing in mind that parallel lines have the same exact slope, then any parallel line to the one above will have the same slope as that one.
