Solve for y. ln(y-1)-ln2=x+ln x
alexandr402 [8]
ln(y - 1) - ln(2) = x + ln(x)
e^{ln(y - 1) - ln(2)} = e^{x + ln(x)}
\frac{e^{ln(y - 1)}}{e^{ln(2)}} = e^{x} * e^{ln(x)}
\frac{y - 1}{2} = e^{x} * x
\frac{1}{2}y - \frac{1}{2} = xe^{x}
2(\frac{1}{2}y - \frac{1}{2}) = 2xe^{x}
y - 1 = 2xe^{x}
y = 2xe^{x} + 1

A grounds crew is marking out a circular logo at the center of a football field. The logo will
patriot [66]

Answer:

circumference of a circle formula is C=2*pi*r

Step-by-step explanation:

then  

141.3 = 2*pi * r

solve for r

141.3/ (2*pi) = r

22.48859 feet

diameter is  2*r

2*22.48859= 44.9771 feet

divide by 3 because there are 3 feet in one yard

44.9771/3= 14.99239 yds.  

it doesn't say to round off, but I would call this 15 yds.

Diameter is 15 yards   ± .008 yds  That's just about 1/4 of an inch

Order from least to greatest ! 1.36,1.3,1.63 and this other 0.42,3.74,3.47.
frosja888 [35]
If you are putting them all in order from least to greatest it would be 0.42, 1.3, 1.36, 1.63, 3.47,3.74. But, if you are separating them the first set of three numbers you wrote would be ordered 1.3, 1.36, 1.63. Then, the second set would be ordered 0.42, 3.47, 3.74. Hope this helped!!!
