Answer:
20
Step-by-step explanation:
Side of the square = hypotenuse of triangle = √(4² + 2²)=√(16 + 4)=√(20)
Area of a square = (side)² = (√20)² = 20 units²
Answer:
3/16
Step-by-step explanation:
5 blue, 6 red, 3 black, and 2 yellow
total number of marbles = 5 + 6 + 3 + 2 = 16
p(black) = (number of black marbles)/(total number of marbles)
p(black) = 3/16
Answer: 3/16
Answer:
a) 198.7% interest
Not too sure about answer to (b)
b) 4.75% annualized
Step-by-step explanation:
a) i used Interest = Principal x Rate x Time
40 = 525 x
x r
40 = 20.13r
r = 1.987 or 198.7%
b) i used this proportion:
=
'x' represents annualized rate
1/24 represents 2 weeks out of a year
1/24x = 1.98
x = 4.75%
The answer is: A - f(x) = 1/2 cos (x)
