Answer: 40.82
Step-by-step explanation:
Use pythagoras theorem to solve
Root 35 squared + 21 squared = 40.82
Answer:
- 6 - 3i
Step-by-step explanation:
Given
(- 3 - 2i) - (3 + i) ← distribute both parenthesis
= - 3 - 2i - 3 - i ← collect like terms
= - 6 - 3i
Answer:
(g o f)(x) = x
Step-by-step explanation:
Given the functions f(x) = 2/x and g(x) = 2/x
(g o f)(x) = g(f(x))
g(f(x)) = g(2/x)
Replace x with 2/x in g(x)
g(f(x)) = 2/(2/x)
g(f(x)) = 2 * x/2
g(f(x)) = 2x/2
g(f(x)) = x
Hence the composite function g o f)(x) is x
F(x) = mx + b represent the straight line. If m ≠ 0 then the domain and the range of that function are real number.
Answer:
O x = - 6 or x = 2
Step-by-step explanation:
x² + 4x - 4 - 8 = 0
x² + 4x - 12 = 0
x² + 6x - 2x - 12 = 0
x(x + 6)x - 2(x + 6) = 0
(x + 6) (x - 2) = 0
x + 6 = 0 or x - 2 = 0
x = - 6 or x = 2
Thus, x = - 6 or x = 2
