Answer:
cost of knife = £5.52
Step-by-step explanation:
Assume:
Cost of Knife = a
Cost of Spoon = b
a = 3b ----------------------(1)
12a + 9b = £82.80 -------(2)
Substitute equation (1) in equation (2)
12 * (3b) + 9b = £82.80
36b + 9b = £82.80
45b = £82.80
b = £1.84
Therefore, cost of knife = a = 3 * £1.84 = £5.52

Answer:
Step-by-step explanation:
Rule
The sin of any angle = cos(90 - the angle used for the sine)
Sin(64) = cos(90 - 64)
Sin(64) = cos(26)
Check
Sin(64) = 0.8988
Cos(26) = 0.8988
1). [(6,1), (6,2), (6,3)] 2). [(0,5), (5,-1), (5,9)] 3). [(1,-6), (3,-5), (1,0)] 4). [(0,8), (1,7), (2,6)]. Which of the followi

Again, look for repeated entries in the domain. If present, the relation cannot be a function. 1 maps 6 to 1, 2, and 3; 2 maps 5 to -1 and 9; 3 maps 1 to -6 and 0; and only 4 has no double mapping. Therefore 4 is a function and the answer.
