Answer:
y-int: -9, slope: 3/5
Step-by-step explanation:
To find the circumference of a circle, you can use the formula
πd, where d is the diameter of the circle.
In this instance, we can tell from the picture that the diameter of the circle is 16 inches.
Therefore, the exact circumference of the circle is
C. 16pi inches
It’s hard to help, since there’s no picture :/
Answer:
- boat: 6 mph
- current: 2 mph
Step-by-step explanation:
The relationship between time, speed, and distance is ...
speed = distance/time
For boat speed b and current speed c, the speed downstream is ...
b +c = (16 mi)/(2 h) = 8 mi/h
The speed upstream is ...
b -c = (16 mi)/(4 h) = 4 mi/h
Adding the two equations eliminates the c term:
2b = 12 mi/h
b = 6 mi/h . . . . . divide by 2
Solving the second equation for c, we get ...
c = b -4 mi/h = 6 mi/h -4 mi/h = 2 mi/h
The speed of the boat in still water is 6 mi/h; the current is 2 mi/h.
