<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>
The name is the second option y= (2/3)x +5. Hope this helps
Step-by-step explanation:
f(x) = 9 * 81^x
When x = -1/2,
f(-1/2) = 9 * 81^(-1/2) = 9 * (1/9) = 1.
There is an invisible +0 at the end. this means the y intercept is 0
<span>Para obtener el otro número, debemos dividir la base por el área. Haciendo eso obtenemos 8.6 Para verificar, multiplicamos 10.4 y 8.6.
10.4 x 8.6 = 89.44
Entonces la respuesta es B.) 8.6</span>
