Domain is the x-coordinate and range is the y - coordinate
Answer:
rate of motorboat: b
rate of current: c
So the rate the boat travels upstream is $b - c$, and the rate it travels downstream is $b + c$
Step-by-step explanation:
d = rt
200 = (b - c)\cdot 5
200 = (b + c)\cdot 4
b - c = 40
b + c = 50
Adding these equations, we get:
2b = 90
b = 45
So
c = 50 - 45 = 5
<u>Therefore the rate of the boat is 45kph, and the rate of the current is 5kph</u>

Answer and explanation:
A center chord in a circle is the diameter of that circle. Therefore a center chord of a circle is different from other chords that touch two points on the circle but not in the center of the circle. A diameter of a circle is the chord that runs the length of the center of the circle touching two points at the edge of the circle. A diameter is twice the radius of the circle. So if the diameter of the circle is 12cm then the radius of the circle is 6cm
ANSWER
Given
The equation is
The equation of a rectangular hyperbola is xy = c²
where c is constant
thus above is the equation of the rectangular hyperbola.
First case
the graph of this equation is shown below.
Second case
is reflected over the y -axis
than the equation becomes
the graph is shown below.
Third Case
translated down 2 units to form f(x)
than the equation becomes
