Answer:
, 
Step-by-step explanation:
Let be
the end of the terminal side of angle
in standard position, that is, an angle measured with respect to +x semiaxis. By Trigonometry, we know that the sine and the cosine of the angle are, respectively:
(1)
(2)
If we know that
and
, then the sine and the cosine of the angle are:




Answer:
C.
Step-by-step explanation:
angle C is opposite to side/line AB
Answer:
B or 4![\sqrt[]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B3%7D)
Step-by-step explanation:
I could be wrong as I'm very new to this math but I believe its 4
for #1 it is y=-3/2x+4 the -3/2 is the slope and the 4 is the y intercept
for #2 it is y=6/+2 the 6/2 is the slope and the 2 is the y-intercept
the y-intercept is where the line passes through the y axis
Answer:
The explicit form for this sequence is
for all
.
Step-by-step explanation:
The explicit form of an arithmetic sequence of numbers is given by the formula
, where
is the first term of the sequence,
is the difference between two consecutive terms of the sequence, and
.
We know that the first four elements for the arithmetic sequence are
.
To find the general formula for this problem we only need to calculate
in the above formula.
For n=2, we have

if we replace
and
and solve for
we obtain


Therefore the explicit form is
for all
.
