Answer: Its light-collecting area would be 25 times greater than that of the 10-meter keck telescope.
Step-by-step explanation:
1. To solve this problem you must apply the formula for calculate the area of a circle, which is shown below:
Where<em> r</em> is the radius of the circle.
2. The diameter of a circle is:
Where <em>r</em> is the radius of the circle.
3. Therefore, keeping this on mind, you have that the light-collecting area of a 50-meter keck telescope is:
4. And the light-collecting area of a 10-meter keck telescope is:
5. Divide 
by 
, then:
6. Therefore, its light-collecting area would be 25 times greater than that of the 10-meter keck telescope.
Step-by-step explanation:
53-5 is 48
48/6 is 8
X=8
therefore it's 8
Answer:
Set of all real numbers
Step-by-step explanation:
Given in the question the equation:
f(x) = ∛(x)
The domain of a cube root function is the set of all real numbers.
The interval notation (-∞ , ∞)
Cube Root of negative numbers exists:
Negative numbers can't have real number square roots, but negative numbers can have real number cube roots because when you are multiplying an odd number of negative numbers, the result is negative.
Example
(-2)³ = (-2)(-2)(-2) = -8
Answer:
84.05 lbs, I think...
Step-by-step explanation:
I divided 164 by 80 and got 2.05
Then I multiplied 2.04 by 41.......I might be wrong... But hopefully I'm not..
