2.5 X 10^-3 is the scientific notation for 0.0025
<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>
Answer: The quadrilateral used here is a trapezium.
Start by writing it out like this:
17.50
<u>* 2.48 </u>
Make sure that all the places are in correct order. Notice that I added a ZERO in the place that had nothing there.
Move the decimal point so everything is a whole number. You have moved it 4 times.
Now, starting from 8, multiply it by 0, then 5, then 7, and lastly, 1. Now go to the next number (4) and do the same, this time though, put a zero in the first spot. Every new number, add another zero.
After you are done, add them up. Now move the decimal point starting from the right and into the number 4 times. Take out the zeros.
Your answer should be: 43.4
Answer:
1/x^4
Steps:
(1/2x)^4 = <em>1/2^4x^4</em>
= 16 * 1/2^4x^4
Multiply fractions: <em>a * b/c = a * b/c</em>
= 1 * 16/2^4x^4
Multiply the numbers:<em> 1 * 16 = 16</em>
16/2^4x^4
Factor 16: <em>2^4</em>
= 2^4/2^4x^4
Cancel the common factor: <em>2^4</em>
= 1/x^4
