Step-by-step explanation:
a) r=d/t ( same as formula of speed)
b) r= 665280/3=221760 feet/hr
c) distance in miles = 665280/5280= 126
so r=126/3 = 42 miles/hr
d) i think using miles makes more sense cz using feet will result in greater number of values so there is a greater chance of human error
Answer:
-1772
Step-by-step explanation:
The nth term of an arithmetic sequence is expressed as;
Tn = a+(n-1)d
a is the first term
n is the number of terms
d is the common difference
From the sequence
a = 28
d = 8-28 = -12-8 = -20
n =91(since we are looking for the 91st term)
Substrate
T91 = 28+(91-1)(-20)
T91 = 28+90(-20)
T91 = 28-1800
T91 = -1772
Hence the 91st term is -1772
