Answer:
Q.D.E=(5+2i).(5-2i).i = (25-4i²)i = 25i-4i³
Step-by-step explanation:
Answer:
Step-by-step explanation:
12). By applying Pythagoras theorem in the given right triangle,
Hypotenuse² = (Leg 1)² + (Leg 2)²
x² = 7² + 7²
x² = 2(7)²
x = 
x = 
13). By sine rule,
sin(60)° = 
y = 
y = 18
By cosine rule,
cos(60)° = 
x = 
x = 
14). By applying Pythagoras theorem in the given right triangle,
12² = x² + x²
144 = 2x²
72 = x²
x = √72
x = 6√2

Answer:
4m/s²
Step-by-step explanation:
Given that:
Force F is directly proportional to acceleration a
F α a
F = ka
Where k is the constant of proportionality
36 = 6k
Solve for K
36 = 6k
k = 36/6
k = 6
If force = 24 ; acceleration =
24 = ka
k = 6
24 = 6a
a = 24/6
a = 4m/s²
Answer:
Relative frequency for each discount :
10% - 0.4925, 20% - 0.3325, 40% - 0.175
Since only 33.25% of customers got 20% discount, it is not an appropriate method.
Step-by-step explanation:
relative frequency = number of frequency/total number of frequency
you can find out relative frequency for each number and add them up to get relative frequencies of discounts.
