Alton has been recording the number of apples on his apple tree each week, as shown below: week apples 2 15 3 22 4 29 5 36 the function representing alton's apples per week is f(w) = 7w + 1. what does the 1 represent? the number of apples at the start the week number when alton recorded the apples the number of apples alton had in total the number the apples increased by each week

The correct option is 1.

Step-by-step explanation:

It is given that Alton has been recording the number of apples on his apple tree each week, as shown below

Week    Apples

  2             15

  3            22

  4            29

  5            36

The function representing alton's apples per week is

            ..... (1)

The slope intercept form of a line is

             .... (2)

Where, m is slope and b is y-intercept.

From (1) and (2), we get

The slope of the function is 7 and y-intercept is 1.

It means the number the apples increased by 7 each week and the initial number of apples is 1.

Since 1 represent the number of apples at the start, therefore the correct option is 1.

17.5

Step-by-step explanation:

The ratio of "pure drug" to liquid is 35:150

Therefore to evaluate for 75 mls we get the ratio 75/2150 or simply 1/2

multiply 35 by the ratio 1/2

35/2=17.5
