Answer:
(x-2)^2 + (y+5)^2 = 16
Step-by-step explanation:
Answer:
(B) π/12 + π/6 k
Step-by-step explanation:
Points of inflection are where f"(x) = 0 and changes signs.
f(x) = cos²(3x)
f(x) = (cos(3x))²
f'(x) = 2 (cos(3x))¹ × -sin(3x) × 3
f'(x) = -6 sin(3x) cos(3x)
Using double angle formula:
f'(x) = -3 sin(6x)
f"(x) = -3 cos(6x) × 6
f"(x) = -18 cos(6x)
0 = -18 cos(6x)
0 = cos(6x)
6x = π/2 + 2πk or 6x = 3π/2 + 2πk
We can simplify this to:
6x = π/2 + πk
x = π/12 + π/6 k
We are asked to check which among the choices with given set of points satisfy the inequality
y > x +2y < 2x +3
The answer is "None" of the given choices satisfy the linear inequality. Each choice has a point (2,2) which dissatisfy the equation.
y > x +2y <2x+3
2 > 2+2(2) < 2(2)+3
2> 6 <7
Answer:
Step-by-step explanation: ok
7.
Multiply 30 by 1.47 and that gets how many scale units you have. Then divide the scale by 6.3 and you’ll get 7.
Hope this helps!
