Answer:
The coordinates of A would be (-1, 2)
Step-by-step explanation:
In order to find this, use the mid-point formula.
(xA + xB)/2 = xM
In this, the xA is the x value of point A, xB is the x value of point B, and xM is the x value of M. Now we plug in the known information and solve for xA.
(xA + 5)/2 = 2
xA + 5 = 4
xA = -1
Now we can do the same using the midpoint formula and the y values.
(yA + yB)/2 = yM
(yA + 10)/2 = 6
yA + 10 = 12
yA = 2
This gives us the midpoint of (-1, 2)
25 square yards is the surface area
Answer:
512
Step-by-step explanation:
8³ is the same as saying 8×8×8
8×8×8= 512

22,000÷100= 220
1% = £220 depreciation
15 % = 220×15= 3,300
45% = 3,300×3=9,900
22,000-9,900= £12,100
final answer is £12,100 after 3 years .
