Answer:
The coordinates of b are: (x, y) = (3, -4)
Step-by-step explanation:
Given
Given that the midpoint of the ab is:
The coordinates of a are:
To determine
The coordinates of b = ?
Let b (x, y) be the coordinates of b.
Given that the midpoint of the ab is m(-2, -1)
Thus,
(x - 7) / 2 = -2, (y + 2) /2 = -1
now solving
(x - 7) / 2 = -2
(x - 7) = -2 × 2
x - 7 = -4
adding 7 in both sides
x - 7 + 7 = -4 + 7
x = 3
and solving
(y + 2) /2 = -1
(y + 2) = -1 × 2
y + 2 = -2
subtracting 2 from both sides
y + 2 - 2 = -2 - 2
y = -4
Thus,
The coordinates of b are: (x, y) = (3, -4)
Answer:
The tree is 28 feet in height.
Step-by-step explanation:
This is a proportion problem. You need to keep the height of the objects on one side of the ratios and the length of the shadows on the other.
74 / x = 102/39 Cross Multiply
102x = 74*39 The inches as a unit cancel out.
102x = 2886 Divide by 102
x = 2886/102
x = 28.29 feet
