9514 1404 393

Answer:

  a. 0.6 h

  b. 1.3 h

  c.  C -- No

  d. 4.2 mi/h

Step-by-step explanation:

a. The relationship between time (t), speed (s), and distance (d) is ...

  t = d/s

The time spent running 4 miles at 7 miles per hour is ...

  t = (4 mi)/(7 mi/h) = (4/7) h ≈ 0.6 h

__

b. The time spent walking home is ...

  t = (4 mi)/(3 mi/h) = 4/3 h ≈ 1.3 h

__

c.  C -- No, less time is spent at 7 mi/h

__

d. The average speed is ...

   s = d/t = (4 mi +4 mi)/(4/7 h +4/3 h) = (8 mi)/(40/21 h) = 4.2 mi/h

kakasveta [241]

Answer:

Range is  3 <= g(x) <= 27.

Step-by-step explanation:

The range  is the values of g(x) for the given domain.

When x = 0 g(x) = 3(0)^2 - 6(0) + 3 = 3.

When x = 4 g(x) = 3(4)^2 - 6(4) + 3 =  27.
