This is NOT an arithmetic sequence because there is no common difference.  It is a geometric sequence because there is a common ratio.  Meaning that each term is a constant ratio or multiple of the previous term.  The recursive rule for this geometric sequence is:

a(n)=3*a(n-1), a(1)=3

The number of bacteria (b) in a batch of refrigerated food is given by the function b(t) = 20t2 − 70t + 300, where t is the temp
nata0808 [166]
We want to combine b(t) and t(h) to create a function that described the number of bacteria, b, as a function of time, h. 
This function can be called b(t(h)), or b(h).
Consider the function b(t), or bacteria as a function of temperature. 
b(t) = 20t² - 70t +300
This describes the number of bacteria, given the temperature.

t(h) described the temperature as a function of time, specifically hours after refrigeration:
t(h) = 2h + 3

Since the time h can tell us the temperature t, and the temperature t can tell us the # of bacteria b, we can create a function that tells us the number of bacteria, b, given hours following refrigeration, h.

To do this, we plug t(h) in for every t in the b(t) function:
b(t(h)) = 20 (2h+3)² - 70(2h+3) + 300
We can also call this function b(h), since we now can express b as a function of h.

Simplify the function:
b(h) = 20 (4h²+12h+9)-14h-210+300
b(h) = 80h² +100h +270

The Answer is B

Step-by-step explanation:

The average speed is distance over time.

34 mi / 0.5 hr = 68 mph
