Answer:
our answer will be in quadrant 1 only.
Step-by-step explanation:
From the
cos−1(1) we have the side adjacent to ∠θ=1 and the side hypotenuse=2 . So this is a 30∘−60∘−90∘ triangle and θ=60∘therefore the opposite to ∠θ=√3.
Note that from the restrictions for the range of inverse circular functions cos−1x is restricted to quadrants 1 and 2 and since the argument is positive 12 our answer will be in quadrant 1 only.
The question tackles about arithmetic sequence.
Arithmetic sequence has the formula:
an<span> = a</span>1<span> + (n – 1)d.
</span>where
an = number at nth term
a1 = 1st term
n = number of terms
d = common difference.
an<span> = a</span>1<span> + (n – 1)d.
</span>a1 = -10
d = -2
n = 10
a2 = -10 + (2-1) -2
a2 = -12
if we continue until a10, the sequence will be
-10, -12, -14, -16, -18, -20, -22, -24, -26, -30
Hey bestie. I really don’t know what to say except for Pinterest is probably the place for you. There’s a bunch of people looking for friends there. Best of luck.
The answer is 36 because if you find the multiples of 3 12 18 the same is 36.
Hope this helps :D
