Answer:
Step-by-step explanation:
Let he speed of the boat on the lake is x.
<u>Considering the speed of the current it will take him:</u>
- 22.5/(x + 6) + 22.5/(x - 6) = 9
- 2.5 / (x + 6) + 2.5 / (x - 6) = 1
- 2.5(x - 6 + x + 6) = (x + 6)(x - 6)
- 2.5*2x = x² - 36
- x² - 5x - 36 = 0
- x = (5 ± √(5² + 4*36))/2 = (5 ± 13) / 2
- x = (5 + 13)/2 = 9 mph (negative root is discarded as the speed should be positive)
Slope: (y2-y1)/(x2-x1)
(-11-1)/(6-(-3)) = -12/9 = -4/3
The slope is -4/3
Answer:
132
Step-by-step explanation:
becaue the sequence is going doubling
12*2 24*2 48*2 96*2 so your answer is 132
The Answer is 750/40 = 18 33/40
To get this answer you have to find the LCM which in this case is 40 and then multiply to make it into that fraction(multiply both number, and numerator, and denominator) then add. When you add these you get 750/33 and then you have to simplify by dividing and you get 18 33/40
9.407x10-11 is the answer
