Answer:

Step-by-step explanation:

step one:

Given the function

y = 14 +2.31x + 4.50

we can solve for the rate of change by applying differentiation.

step two:

differentiating y which is cost with respect to x which is the miles

dy/dx= 0+2.32+0

dy/dx=2.32

Hence the rate of change of cost in the dollar to a mile is

2.32dollar/mile

Answer:

a. 15 = d/600 + 12 + d/480

b. 800 feet

Step-by-step explanation:

a. Let distance between hive and flowerbed be "d" feet

Speed of bee during motion from hire to flowerbed = 10ft / sec = (10*60)fit/minute

Speed of bee during reverse motion = 8 ft/sec = (8*60)ft/min

Time which the bee stayed at flower bed = 12 minute

Time of its total journey = 15 minutes

Total Time = Time of travel from hive to flowerbed + Time of staying in flowerbed + Time of reverse travel

15 = d/10*60 + 12 + d/8*60

15 = d/600 + 12 + d/480....................(Required equation)

b. 15 = d/600 + 12 + d/480

d/600 + d/480 = 15 - 12

d/600 + d/480 = 3

4d + 5d  =  3

 2400

9d = 2400 * 3

9d = 7200

d = 7200/9

d = 800 feet

Hence, the flowerbed is 800 feet far from the hive.

Step-by-step explanation:

Step-by-step explanation:

For number 1, the rate is 20km/140min

So you divide so the rate becomes 1km/(?)

20/20=1

1km/7min

Then to get it to 8km/(?) multiply both sides by 8

1x8=8

7x8=54

8km/54min
