It's scientific notation, so 1.4x10^7 would be 14000000 <span />
A permutation is where there is a difference in positions where the things will be selected into (order matters). Combination is where order doesn’t matter. I have sorted them but I am not sure about the starting line up one. If the players are selected into specific positions then it would be a permutation.
Answer:
Q1.
AC is the greatest side, therefore is hypotenuse. AB and BC are legs.
B is 90 deg as the two legs cross at this point.
<u>Ratios:</u>
- sin = opposite / hypotenuse
- cos = adjacent / hypotenuse
- tan = opposite / adjacent
BC is opposite to A and adjacent to C
AB is adjacent to A and opposite to C
- sin A = cos C = 8/10 = 4/5
- cos A = sin C = 6/10 = 3/5
- tan A = cot C = 8/6 = 4/3
- tan C = cot A = 6/8 = 3/4
Q2.
a) Answered above
b) Answered above
Answer:
4 sweaters
Step-by-step explanation:
If the ratio is 7:2, then 14//7 = 2
2x2=4
