Answer: so to give a hint the graph is not porportional bc it does not run through the orgin so there for the equation you have to look at the first dot describe that write down the points and see how far apart they are by dividing them
Step-by-step explanation:
hope this helps and plz brainliest ( if you wanna of course )
Answer:
To find the exact vale of atan(-sqrt(3)) we're going to need the help of a calculator
atan(-sqrt(3)) = -1.04719755 rads.
If you take a look at the important angles, you will notice that the arc is minus 60 degrees which equals -1.04716755 radians.
When converting a larger unit to a smaller one, you multiply. when you convert a smaller unit to a larger one, you divide.
When you're trying to find something in the simplest form, you have to find a common denominator. The best way to do this is to find the factors.
Factors of 3= 1, 3
Factors of 28= 1,2,4,7,14,28
In this case, the lowest factor is one, which is what they are currently in.
Therefore, 3/28 is currently in its simplest form
<span>Half-span is half of span. Pitch of the roof is calculated as rise/(span/2). In this case, rise is 8 feet and span is 30 feet. So, the pitch can be calculated as 8/(30/2) or 8/15. Pitch is normally represented as the number of inches of rise per foot. So, to reduce 8/15 to match a foot, we multiply it by 12. So, (8/15) * 12 gives us 6.4 inches of rise per foot.</span>
