Answer:
a(7) = -0.4
Step-by-step explanation:
The general formula for a geometric progression is a(n) = a(1)*r^(n - 1), where r is the common ratio. In this problem, a(1) = -6250. To find r, we divide 1250 (the 2nd term) by -6250 (the 1st term), obtaining r = -0.2.
Then the formula for THIS geometric progression is
a(n) = -6250*(-0.2)^(n - 1).
Thus, the 7th term of THIS progression is
a(7) = -6250*(-0.2)^(7 - 1), or -6250*(-0.2)^6, or -0.4
Answer:
C
Step-by-step explanation:
A and B are wrong and with D they wouldn't be lines so imma go with C.
Sorry if it's wrong.
1st piece = x
2nd piece = x+2
3rd piece = x+2+3 = x+5
37 = x +x+2 + x+5 =
37 = 3x+7
30=3x
x = 30/3 = 10
1st piece = 10 inches
2nd piece = 10+2 = 12 inches
3rd piece = 10+5 = 15 inches
C
He payed $10.95 for 6 flowers. You want to find the price per each flower.
An equation to model this situation would be 6x = 10.95 where x = price per flower.
To solve this divide each side by 6.
10.95/6 = 1.825
Essentially to find the price per an individual thing you need to divide the total price by the amount of the item purchased.
He payed $1.825 per flower.
Answer:
Hailey's distance from home
Step-by-step explanation:
as time passes, the y value get ssmaller and smaller. ultimately becoming zero.
for the first option, if she is riding her bike away from school, her distance from school would not be getting smaller and smaller
the height of the tree would not be getting shorter and shorter
the number of students on a bus would be increasing on the way to school
however, as hailey approaches her house, her distance from the house would be getting smaller
