Isobel is pulling water up from an old-fashioned well. she lifts the bucket of water at a rate of 4 ft/s, and after 1 s, the bucket is 1 ft below the top of the well. select the equation in point-slope form for the line that represents the height of the bucket relative to the top of the well.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.

Let be "y" the height of the bucket relative to the top of the well and "x" the time.

We know that:

- She lifts the bucket of water at a rate of , this means that:

- After 1 second, the bucket is 1 feet below the top of the well. This means that:

When ,

Knowing this, we can substitute the known values into   and solve for "b":

Therefore, we get that the equation in Slope-Intercept form for the line that represents the height of the bucket relative to the top of the well is:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
