Answer:

Part 1) $m$

Part 2) $m$

Step-by-step explanation:

Part 1) Find the measure of angle OAD

we know that

OA=OD=radius of the circle

If line AD≅ line AO

then

The triangle AOD is an equilateral triangle

Remember that

An equilateral triangle has the three equal sides and the three internal angles equal (60 degrees each one)

$m$

Part 2) Find the measure of angle DBA

we know that

The inscribed angle measures half that of the arc comprising

$m$

$arc\ AD=m$ ----> by central angle

substitute the value

$m$

Answer:

a) 5/9

b) 7

c) 5

Step-by-step explanation:

For a)

One of the rules for logs is that if there is a logarithm subtracted by a logarithm and they have the same base, it is the same as the log with the same base and the arguments are divided:

$log_{x}z -log_{x} y$ = $log_{x} \frac{z}{y}$

so for this problem, they have the same base, so you can use this rule:

$log_{4} 5-log_{4}9 = log_{4}\frac{5}{9}$

For b)

This is very similar, except instead of dividing the arguments, you want to multiply them.

So this is kind of saying "8 multiplied by x equals 56"

which is 7

For c)

If the argument has its own exponent, it can be brought to the front of the log like so:

$log_{10}x^{y} = ylog_{10}x$

This one is a bit tricky because you have to actually set 32 into an exponent form first.

$32 = 2^{5}$

Then we can bring that 5 in front of the logarithm

$log_{6}2^{5} = 5log_{6}2$

So the answer is 5

a student played a computer game 500 times and won 370 of these game. he then won the next "x" games and lost none. he has now w

a_sh-v [17]

So, this is a proportion problem. If we express 75% as a fraction (3/4ths), we have:

$\frac{370+x}{500+x}=\frac{3}{4}$

Since he won all of his games, we add the number won (x), to the number previously won and divide it by the total games played which is just the previous games played plus the number of current games played, so since he lost no games we still add x to the denominator as well. Solving this gives us:

$4(370+x)=3(500+x) \implies\\ 1480+4x=1500+3x \implies \\ x=20$

That x value is 20.
