Answer:
The question is incomplete, the complete question is "Changing Bases to Evaluate Logarithms in Exercise, use the change-of-base formula and a calculator to evaluate the logarithm. See Example 9.

![log_{4}7=1.404\\](https://tex.z-dn.net/?f=log_%7B4%7D7%3D1.404%5C%5C)
Step-by-step explanation:
From the general properties or laws of logarithm, we have the
![log_{a}b=\frac{logb}{loga} \\](https://tex.z-dn.net/?f=log_%7Ba%7Db%3D%5Cfrac%7Blogb%7D%7Bloga%7D%20%5C%5C)
where both log are now express in the natural logarithm base.
i.e ![log_{a}b=\frac{lnb}{lna}\\](https://tex.z-dn.net/?f=log_%7Ba%7Db%3D%5Cfrac%7Blnb%7D%7Blna%7D%5C%5C)
hence we can express our
.
the value of ln7 is 1.9459 and ln4 is 1.3863
Hence
.
![log_{4}7=1.404\\](https://tex.z-dn.net/?f=log_%7B4%7D7%3D1.404%5C%5C)
Answer:
211 × 9 is 1899 so rounding to nearest thousands would be 2000
Answer:
31.9 mi
Step-by-step explanation:
AC/sin(angleABC) = AB/sin(angleACB)
Center of the door
26 1/3 divided by 2
change to an improper fraction
(3*26+1)/3 =79/3
79/3 divided by 2
copy dot flip
79/3 * 1/2
79/6
change to a mixed number
13 1/6
10 1/4 divided by 2
change to an improper fraction (4*10+1)/2 = 41/4
41/4 divided by 2
copy dot flip
41/4 * 1/2 =41/8
change to a mixed number
5 1/8
the left of the bar should be 5 1/8 from the center
to find how far from the left side to place the bar
13 1/6 - 5 1/8 =
get a common denominator
13 4/24 - 5 3/24= 8 1/24 inches
Answer: place the bar 8 1/24 inches from each edge
