Answer:
9.22
Step-by-step explanation:
The distance formula is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
Using the given coordinates, the distance between them is ...
d = √((8-(-1))^2 +(0 -(-2))^2) = √(9^2 +2^2) = √85 ≈ 9.22
The length of AB is about 9.22 units.
Answer:
a. A(0) is $2500 and A(10) is $3700.61
b. The beginning value and the value after ten years
c. 17.673 years
d. That after roughly 17 and a half years, his investment will be doubled.
Answer:
98 boxes of tile
Step-by-step explanation:
How would it be 32 thats more than he bought
8 months; $740
75x+140=90x+20
Find x then plug it in to find the cost
Okay. fist off don't think of them as 5 units each, but 1. so if you were to put it on graphing paper and box squares each time. you would be able to get 8 in for both sides to make a square. Area then would be 1600ft squared because 8 ×5 is 40 and 40×40 is 1600. then you calculate how many squares you used. 8×8=64. and 80-64=16 so 16 pieces are left over. then 9×9 (increasing the square) is 81. so 17 pieces to increase it.
