Answer:
B
Step-by-step explanation:
The red graph is the graph of y = f(x) translated horizontally by 3 units
Given f(x) then f(x + a) is a horizontal shift of a units
• If a > 0 then shift to the left of a units
• If a < 0 then shift to the right of a units
Here f(x) has been shifted 3 units to the right, thus
y = f(x - 3) → B
- 57 - 12i
distribute the parenthesis
= 81i² - 36i + 24 + 24i
[ note that i² = (√- 1 )² = - 1 ]
= - 81 - 36i + 24 + 24i ( collect like terms )
= - 57 - 12i
Simplify using FOIL 15x3+18x+10x2+12
Answer:
44
Step-by-step explanation:
Angle C is half the angle at the centre, i.e ½(180) = 90
Using triangle ABC
90 + 46 + angle B = 180
Angle B = 180 - 136
Angle B = 44°
Angl 6 measures out to be 62° as its corresponding with angle 8
