Answer:
D
Step-by-step explanation:
(-i)⁵ can be written as (-i)² * (-i)² * (-i). Since (-i)² is the same as i², this equals -1 * (-1) * (-i) which becomes -i.
Answer:
C
Step-by-step explanation:
An angle whose vertex lies on a circle and whose sides are 2 chords of the circle is one half the measure of the intercepted arc.
arc CED is the intercepted arc, hence
arc CED = 2 × 99° = 198°
F(x) as a piecewise function would be:
f(x) = ($3/lb)x, for 0≤x≤10,
= ($1.50/lb)x, for (10,20], and
= ($0.50/lb)x, for (20,40]
To the above must be added $7.50, [0,10] or $12, (10,40]
