She is not correct. She forgot to do g compose f. To verify that functions are inverses of each other, you must also show that g(f(x)) = x. Because g(f(x)) = -x, the functions are not inverses of each other.
Answer:
D
Step-by-step explanation:
0.000009 = 9×10^-6
0.00000003 = 3×10^-8
9×10^-6 / 3×10^-8 =
9/3 × 10^(-6+8) = 3 × 10^2
1046₈ = 1*8³ + 0*8² + 4*8¹ + 6*8⁰
1046₈ = 512 + 0 + 32 + 6
1046₈ = 550₁₀
x= 1.5
positive its correct.
