6. A 30-foot electric line is suspended between the tops of two 20-foot electric poles on level ground. The lowest point of the line is 5 feet above the ground. What is the distance between the two electric poles?

answer-

a. the total cost of a taxi ride includes an initial charge of approximately $3.30

solution-

in the graph,

x axis represents the distance traveled and

y axis represents the total fare

the best fit line intersects the y axis approximately at 3.30 or y-intercept is 3.30. at x=0, i.e when the taxi is still, the value of y or the cost of the fare is 3.30. that means $3.30 is the fixed charge which will be levied along with the other fare.

the slope of the line represent the cost per mile. as the best fit line is straight line, so the price per mile is constant.

the answer is negative fourteen (-14)

step-by-step explanation:

it would be r^2 - 2rs +s^2

assuming   you mean to square it
