Describe how to determine the average rate of change between x = 3 and x = 5 for the function f(x) = 3x3 + 2. Include the averag

Serhud [2]

Answer:

147

Step-by-step explanation:

Average rate of change is given by the total rise over total run.

$f(x) = 3x^3+2\\f(3)=3*3^3+2=83\\f(5)=3*5^3+2 = 377$

So,

total rise = 377 - 83 = 294

total run = 2

average rate of change = $\dfrac{294}{2} = 147$

Working alone, Ryan can dig a 10 ft by 10 ft hole in 5 hours Castel can dig the same hole in 6 hours how long would it take them

Fed [463]

Answer:

The time taken by both boys to complete work = 2.73 hours

Step-by-step explanation:

Time taken by rayan to dig hole $T_{1}$ = 5 hours

Time taken by castel to dig hole $T_{2}$ = 6 hours

Now the time taken by both persons working together

$T = \frac{T_{1} T_{2} }{T_{1} + T_{2}}$

Put all the values in above formula we get

$T = \frac{ 30 }{6 + 5}$

$T = \frac{30}{11}$

T = 2.73 hours

Therefore the time taken by both boys to complete work = 2.73 hours
