Answer:
The domain is discrete
Step-by-step explanation:
Given

Required
What type of domain is it?
<em>Based on the given options, the domain is continuous.</em>
From the question, we understand that x represents the hours spent in climbing the rock.
The climber can decide to climb for 1 hour, 2 hours, ½ hour, ⅓ hour, ¼ hour, etc..
A domain is said to be discrete if it can only take integers (i.e. whole numbers), if otherwise, it is continuous;
So, since x is not limited to only whole numbers, then we can conclude that the domain of x is continuous
Answer:1920
Step-by-step explanation:
You can simplify it by multiplying the 24 by 2 to get 48 then get 48 time 40 which is 1920
Professor Dan Healy, one of my Engineering instructors back in prehistoric times, had a favorite way of showing us how to do this kind of problem ... I mean the kind that's incredibly easy, but your own fear gets in the way and convinces you that you can't handle it. Here is Prof. Healy's method.
For a few moments, call the square root of 5 by the name "cow".
cow - x = 4 . Solve this equation for 'x' :
Add 'x' to each side of the equation: cow = 4 + x
Subtract 4 from each side: cow - 4 = x
Now, we can put the real value back in place of 'cow' : <u>√5 - 4 = x</u>
That right there is a perfect solution. But If you absolutely need to
know the number, then grab your calculator:
√5 = 2.2361 (rounded)
x = √5 - 4 = 2.2361 - 4 = <u>-1.7639</u> (rounded)
