Which of the following examples have a constant rate of change?
Paladinen [302]

Answer:

B/second option

Step-by-step explanation:

The first option is wrong because you make 30 meatballs in 30 mins but then 30 meatballs in 20 mins. If it was constant then in 20 mins you make less meatballs.

The last option is wrong because if bacteria triples, then that is exponential, not constant change.

Only the middle option makes sense. The rate of change is $35 for each hour!

please give thanks by clicking the heart button! :)

For the function y= -1+6 cos ( 2π/7(x-5) ), what is the maximum value​
RUDIKE [14]

Answer:

5

Step-by-step explanation:

I'm assuming you want to find the maximum value of y

recall that for any cosine function y = A cos (  g(x) ), where g(x) is any arbitrary function, that A represents the amplitude of the cosine function.

By definition, the amplitude is the maximum the value which the cosine term can take.

hence for your expression:

y= -1 + 6 cos ( 2π/7(x-5) )

max value of y = -1 + (max value of cosine function)

max value of y = -1 + (amplitude of cosine function)

max value of y = -1 + 6 = 5
