Answer:
1x1x1x1x1x1x1x1x1=1^9
Step-by-step explanation:
Answer:
αβ=c/a
α+β=-b/a
α+β=-k/2
-(α+β)²=k
-α²-2αβ-β²=k
-α²-2(1/2)-β²=k
-α²-1-β²=k
Step-by-step explanation:
So to start this question you find the prices of the two types of cups and create a basic formula for them. For the mug it would have a base price of $2.95 and a refill price of $0.50. For the disposable cup it would cost $0.85 a piece.
So for the mug you would take the base price of 2.95 and add it by x amount of refills to find the break even point of the two. So the formula would look like 2.95+0.50x. The other would be 0.85x. Now its just a matter of guess and check to see how many refills it would take for the mug to be cheaper. i hope this helped!
10% is 8.35. 1% is 0.83 so 2% is 1.66. 8.35+1.66=10.01. 83.47+10.01=93.48. 93.48x12=1121.76. The bill will cost £1121.76.
There.... the answer would be in millimeters
