Answer:

$(x-3)^2 + (y-2)^2 = 16$

Step-by-step explanation:

Changing Bases to Evaluate Logarithms In Exercise, use the change-of-base formula and a calculator to evaluate the logarithm.

Ymorist [56]

Answer:

$\frac{3}{2}$

Step-by-step explanation:

Changing Bases to Evaluate Logarithms

$log_{16}(64)$

Apply change of base formula'

$log_b(a)= \frac{log a}{log b}$

log term should be the numerator and denominator is the log base

$log_{16}(64)$

$log_{16}(a)= \frac{log 64}{log 16}$

64 is 4^3 and 16 is 4^2

$log_{16}(a)= \frac{log 4^3}{log 4^2}$

Move the exponent before log

$\frac{3log 4}{2log 4}$

top and bottom has same log so cancel it out

$\frac{3}{2}$

90 x= 81 + 25 I need help ?

charle [14.2K]

Answer:

$x = \frac {53} {45}$

Step-by-step explanation:

Step 1: Combine on the right side

$90x = 81 + 25$

$90x = 106$

Step 2: Divide both sides by 90

$\frac {90x} {90} = \frac {106} {90}$

$x = \frac {106/2} {90/2}$

$x = \frac {53} {45}$

Answer: $x = \frac {53} {45}$

The total number of books in the library is 1155.there are 20 times more nonfiction books than fiction books. How many fiction b

alekssr [168]

There is 20x more nonfiction than fiction so you do
20+1=21
so then to find out what $\frac{1}{21}$ of 1155 is we do
1155÷21=55
so then we times 55 by 20 because there are 20x more nonfiction than fiction
55x20=1100
soo now we know there is
1100 nonfiction books and
55 fiction books
to check whether we are right we can do
1100=55=1155
we are right because there is 1155 books in the library
hope i helped
