<em>"In the xy-plane, the parabola with equation y = (x − 11) ² intersects the line with equation y = 25 at two points, A and B. What is the length of AB" </em>
Here is my answer
Because the parabola intersects the line with equation y = 25 Substituting y = 25 in the equation of the parabola y = (x - 11)², we get
25 = (x - 11)²
<=>x - 11 = ± 5
<=> 
Thus A(16, 25) and B(6, 25) are the points of intersection of the given parabola and the given line.
So the length of AB = √[(16 - 6)² + (25 - 25)²]
= √100 = 10 units
The tall of the actual building will be 216 feet
Step-by-step explanation:
An architect is presenting a scale model of a building she's designed
to the planning committee of college
1. The scale of the model is 1 inch = 18 feet
2. The tallest wall in the model is 12 inches
3. We need to know how tall the actual building will be
Let us used the ratio method
∵ The scale of the model is 1 inch represents 18 feet
∵ The tallest wall in the model is 12 inch
→ Model(in) : Actual(ft)
→ 1 : 18
→ 12 : h
- By using cross multiplication
∴ 1 × h = 12 × 18
∴ h = 216 feet
∴ The actual height is 216 feet
The tall of the actual building will be 216 feet

Answer:
We have to prove,
(A \ B) ∪ ( B \ A ) = (A U B) \ (B ∩ A).
Suppose,
x ∈ (A \ B) ∪ ( B \ A ), where x is an arbitrary,
⇒ x ∈ A \ B or x ∈ B \ A
⇒ x ∈ A and x ∉ B or x ∈ B and x ∉ A
⇒ x ∈ A or x ∈ B and x ∉ B and x ∉ A
⇒ x ∈ A ∪ B and x ∉ B ∩ A
⇒ x ∈ ( A ∪ B ) \ ( B ∩ A )
Conversely,
Suppose,
y ∈ ( A ∪ B ) \ ( B ∩ A ), where, y is an arbitrary.
⇒ y ∈ A ∪ B and x ∉ B ∩ A
⇒ y ∈ A or y ∈ B and y ∉ B or y ∉ A
⇒ y ∈ A and y ∉ B or y ∈ B and y ∉ A
⇒ y ∈ A \ B or y ∈ B \ A
⇒ y ∈ ( A \ B ) ∪ ( B \ A )
Hence, proved......
