Answer:
a(1) = 10
a(n) = a(n-1)·0.6
Step-by-step explanation:
The first term of the sequence is the one listed first: 10. That means a(1) = 10.
The next term of the geometric sequence will be the first term multiplied by the common ratio. That ratio can be found as the ratio of the second term to the first:
r = 6/10 = 0.6
So, the recursive formula is ...
a(n) = a(n-1)·r
a(n) = a(n-1)·0.6
Answer:
The new price is $28
Step-by-step explanation:
In order to find this, multiply the price of the fan by the markup.
$20 * 40% = $8
Now we can add the amount of the markup to the original cost.
$8 + $20 = $28
Answer:
x=15
Step-by-step explanation:
the angle 7x+12 and 63 are on opposite sides of complimentary, meaning they add to 180.
180-63 = 117
117-12 = 105
105/7 = 15
Okay this is very simple
The length of the longest lead is 1 3/4
The length of the shortest lead was 1/4
The difference between the longest lead and the shortest lead is 1 1/2
The length the most students had was 1/2
The of the sum of the two shortest lengths are 3/4
The difference of the longest lead and the second shortest lead is 1 1/4
hope this helps :)
The answer is f(x)=3 or y=3
