Answer:
an = -8 +3(n-1)
an = -11 +3n
f(n) = -11 +3n
Step-by-step explanation:
–8, –5, –2, 1, 4, ...
This is an arithmetic sequence.
We are increasing by 3 each time
-8 +3 = -5
-5+3 = -2
-2 +3 = 1
The common difference is 3
The formula for an arithmetic sequence is
an = a1 +d (n-1)
an = -8 +3(n-1)
an = -8 +3n -3
an = -11 +3n
The nth term is -11 +3n
f(n) = -11 +3n
1 glove costs $48
5 gloves cost $240 (since 5*48 = 240)
1 bat costs $35
b bats cost 35*b dollars, where b is some positive whole number
The total cost of the bats and gloves is 35*b + 240. We simply add the subtotals (240 from the gloves and 35*b from the bats)
Plug in b = 3 and use PEMDAS to evaluate
35*b + 240
35*3 + 240 .... b has been replaced with 3
105 + 240
345
---------------------------------------------------
To summarize:
The cost expression is 35*b + 240 (the cost is in dollars)
The total cost if the coach bought three bats is 345 dollars
It would be x^2+7x-4, you just move everything to one side.
Well, elevation in how high the hill is from sea level, so the higher the mile, the farther away it is from sea level. The one farthest from sea level is Britton and the one closest is Ray.
