A boat moves 15.0 km across a lake in 30.0 min. what was the average speed of the boat in kilometers per hours?

Katen [24]

To work out the average speed you would have to use the formula

AS = 15.0 ÷ 30.0 = 0.5 which is distance divided by time.

The you would do 0.5 x 60 = 30 (60 minutes = 1 hour)

So the average speed would be 30.0 km/h.

How do I figure out b,c, and d

Andrews [41]

Answer:

(b) domain: (-∞, ∞)

(c) f(x) = 3 only at x=1

(d) range: (-∞, 3]

Step-by-step explanation:

(b) The domain is the horizontal extent of the region over which the function is defined. The function f(x) is defined for all x, from -∞ to +∞. The arrowheads on the ends of the graph mean the graph extends to infinity in x and y directions from those points (y goes to -∞, while x goes to ±∞).

__

(c) Locate the horizontal grid line y=3 on the graph. Find all the points where it intersects the graph. There is only one: (1, 3). That is, x=1 is the only x-value for which f(x) = 3.

__

(d) The range of the function is its vertical extent. The graph of f(x) extends from y = -∞ up to y = 3, so that is the range.
