Answer:
x = 13
Step-by-step explanation:
Please use " ln " for the "natural logarithm," not " in. "
Then you have: 2 ln 3= ln (x-4)
We need to get rid of the " ln " operator. Rewrite 2 ln 3 as ln 3² = ln (x - 4).
Then 3² = x - 4, or 9 = x - 4, or x = 13
follows from the fact that the cosine function is
-periodic, which means
. Roughly speaking, this is the same as saying that a point on a circle is the same as the point you get by completing a full revolution around the circle (i.e. add
to the original point's angle with respect to the horizontal axis).
If you make another complete revolution (so we're effectively adding
) we get the same result:
. This is true for any number of complete revolutions, so that this pattern holds for any even multiple of
added to the argument. Therefore
for any integer
.
Next, because
, it follows that
is also true for any integer
. So we have
The rest follows from considering either case and solving for
.
Answer:
the value is x is 8 and y is 7
Answer:
Y = 3/4x - 2
Step-by-step explanation:
Slope = (1 - - 5)/(4 - - 4 =6/8 = 3/4
b = -5 - (3/4)(-4)
b = -5 + 3 = -2
y = 3/4x - 2
