Answer:
<u>-1133</u>
Step-by-step explanation:
<u>Formula for nth term</u>
<u>Finding d</u>
- d = -45 - (-28)
- d = -45 + 28
- d = -17
<u>Solving for a₆₆</u>
- a₆₆ = -28 + 65(-17)
- a₆₆ = -28 - 1105
- a₆₆ = <u>-1133</u>
Six hundred thousand plus eighty thousand plus ten

The value of x in f(x)=4 is 4 because the f in f(x) is just 'naming' the equation, saying that x=a number, in this case, 4.
The cost to equip all the stations in the chemistry lab is calculated as: $393.75.
<h3>How to Calculate Total Cost?</h3>
In this scenario, we are given the following:
Total number of stations = 21 stations
Length of rubber tubing each of the stations in the chemistry lab needs = 5 feet
Total length of rubber tubing needed for all stations in the chemistry lab = 21 × 5 = 105 feet
Cost of 1 rubber tubing = $6.25 per yard
Convert 5 feet to yard:
1 yard = 3 feet
x yard = 5 feet
x = (5 × 1)/3
x = 5/3 feet.
So, the cost of 1 rubber tubing = $6.25 per 5/3
Cost of total length of tubbing needed = (105 × 6.25)/5/3 = (105 × 6.25) × 3/5
Cost of total length of tubbing needed = $393.75
Therefore, the cost to equip all the stations in the chemistry lab is calculated as: $393.75.
