The number of gallons g in a swimming pool being filled with water is G=50x+1,000, where x is the number of hours since sunrise. It has been 10 hours since sunrise. What is the initial value?
To find the initial value, substitute x = 0 into the equation G = 50x + 1,000.
When x = 0,
G = 50(0) + 1,000
G = 0 + 1,000
G = 1,000
Therefore, the initial value is 1,000.
