The distance would be, ((x1-x2)^2+(y1-y2)^2)^0.5
x1=-7,y1=9, x2=-4,y2=2
hence distance = sqrt(9+49) = sqrt (58) = 7.615773106
Answer:
Step-by-step explanation:
First calculate the amount of notebooks and textbook
Cost of 2 notebooks = 2 *8.75
= $ 17.5
Cost of 1 textbook = $ 74.95
Total cost = 17.5 + 74.95
= $ 92.45
Tax = 7% of total cost
= 0.07 * 92.45
= $ 6.47
Total cost = 92.45 +6.47
= $ 98.92
