Answer:
6.25-1.75
Step-by-step explanation:
Step-by-step explanation:
Monique had 6 dollars. She found 25 cents and then bought a book
25 cents = 0.25 dollars
Total dollar she had= 6 + 0.25= 6.25 dollars
Let x be the cost of a book
She ended up with 7 quarters. Convert quarter into dollars
1 quarter = 0.25 dollars
7 quarters = 7 times 0.25=1.75 dollars
So she ended up with 1.75 dollars
Amount she had at the beginning - the cost of book = amount ended up
Number of dollars spent on the book = Amount she had - amount ended
Number of dollars spent on the book=
6.25-1.75
Answer:
Sequence :
Rate of change : -3
Step-by-step explanation:
It is given that the sequence represents by the points (1,8), (2,4), (4,1) and (5,0.5).
We know that the represent the point (n,k). So, we have
It is clear that the above sequence is a geometric sequence because it has common ratio .
First term :
Common ratio :
The nth term of a G.P. is
Therefore, the required sequence is .
We need to find the average rate of change from n = 1 to n = 3.
Therefore, the average rate of change from n = 1 to n = 3 is -3.
