How to find the average rate of change if the function​

Mathematics
1 answer:
Rasek [7]3 years ago
8 0

Answer:

14

Step-by-step explanation:

Average rate of change is given as \frac{f(b) - f(a)}{b - a}

Where,

a = 4,

f(a) = f(4) = (4)² + 3(4) = 16 + 12 = 28

b = 7,

f(b) = f(7) = (7)² + 3(7) = 49 + 21 = 70

Plug in the values into the formula

Average rate of change = \frac{70 - 28}{7 - 4}

= \frac{42}{3} = 14

Sliva [168]

Answer:

26.8 inches of fabrics was used on headband and wristband for each player

Step-by-step explanation:

Headbands for 31 players and 3 couches = 611.66 inches of fabric

Total number of people = 31 players + 3 couches

= 31 + 3

= 34 people

Fabrics per person's headbands = Total inches of fabrics for headbands / total number of people

= 611.66 inches of fabric / 34 people

= 17.99 inches of fabrics per person

Wristband for 31 players = 273.11 inches of fabric

Fabric per person's wristband = total inches of fabrics for wristband / number of players

= 273.11 inches of fabric / 31

= 8.81 inches per person

How much fabric was used on a headband and wristband for each player?

= Fabrics per person's headbands + Fabric per person's wristband

= 17.99 inches + 8.81 inches

= 26.8 inches of fabrics was used on headband and wristband for each player
