The expression log 3 (x-4) is undefined for all values such that
suter [353]
Translate it

remember that log_a(b)=c translates to a^c=b
so we can say it equals y
so
log_3(x-4)=y translates to 3^y=x-4

we want to find the values of x that make it undefined
well, we know that 3^y must be greater than 0
so we do
it is defined for
x-4>0
add 4
x>4

it is defined for all values such that x>4

x = 375 and y = 6300. Option C.

Step-by-step explanation:

From the given data we need to find the value of x and y.

First, we will find out the ratio of area and the force.

\frac{Area}{Force}  = \frac{125}{1875} =\frac{150}{2250} =\frac{175}{2625} = \frac{1}{15}

So,

\frac{x}{5625} = \frac{1}{15}

or, x = \frac{5625}{15} = 375

Again,

\frac{420}{y} = \frac{1}{15}

or, y = 420×15 = 6300

Hence,

x = 375 and y = 6300.

We know that the measure of arc AC = 92 degrees, and x and y are both inscribed angles of this arc, which means that they will have 1/2 of its measure.

Therefore, x = 1/2 (92) = 46 degrees and y = 1/2 (92) = 46 degrees

x = 46, y = 46 is your answer, or the first option
