Step-by-step explanation:
(f+g)(x) means we just add the 2 functions, so we have
(x-3) + 2x² = 2x² + x - 3
(f-g)(x) means we subtract g(x) from f(x), so we have
(x-3) - (2x²) = -2x²+x-3
Assuming that the dot signifies a multiplication sign and not a composition sign, we have
(f*g)(x) = f(x) * g(x)
= (x-3) * 2x²
= 2x³ - 6x²
Plugging -2 in, we get
2(-2)³-6(-2)² = -16 -24 = -40
A because your not dividing it by 5 your subtracting 5 from k divided by 2
R=12cm
circumference=2×pi×r
=2×3.14×12
=75.36cm
area = pi×r^2
=3.14×12×12
=3.14×144
=452.16cm^2
Answer:
69.5%
Step-by-step explanation:
If the original value is 1, the value after the crash is 1-0.41 = 0.59. We want to find the multiplier x so that ...
0.59x = 1
x = 1/0.59 ≈ 1.6949
The percentage increase required is (x -1)×100% ≈ 69.49%.
The stock would have to rise about 69.5%.
