hii! i just wanted to say hope you're having a fantastic day and hope that things are going well (: stay strong and stay safe!
Answer:
√10 / 10
Step-by-step explanation:
tan θ > 0 and sin θ < 0, so θ is in quadrant III. That means cos θ < 0.
cos(θ + π/4)
Use angle sum formula.
cos θ cos(π/4) − sin θ sin(π/4)
½√2 cos θ − ½√2 sin θ
Factor.
½√2 cos θ (1 − tan θ)
½√2 cos θ (1 − 2)
-½√2 cos θ
Write in terms of secant.
-½√2 / sec θ
Use Pythagorean identity (remember that cos θ < 0).
-½√2 / -√(1 + tan²θ)
-½√2 / -√(1 + 2²)
½√2 / √5
√10 / 10
Ƒ(x)=3x^3+12x^2+3x-18 = 3(x-1)(x+3)(x+2)
Answer:
Sequence; 12, 24, 36, 48, 60, 72, 84, 89, 108...
12th value: 144
The sum of all numbers go through the 12th : 936
Step-by-step explanation:
A-1538=1074
a=1538+1074
a=2612
b+718=1074
b=1074-718
b=356
2000-c=1074
c=2000-1074
c=926
2612-356+926=3182
