Answer:
0.50027
Explanation:
ΔA=
Where ΔA is the change in area
There is a 2 since the coefficient for area = 2 x that for the linear coefficient
is the original area
is the coefficient of thermal expansion
And T is the change in temperature
ΔA=2(0.000009)(0.5)(30-0)=0.00027
New area= ΔA+
= 0.5+0.00027=0.50027

Answer:
Option B (350) is the correct answer.
Explanation:
Given:
The temperature is "88°F" i.e., x.
Let number of visitors be "y".
Let the two points will be:
84,225 = (x₁, y₁)
92, 450 = (x₂, y₂)
As we know,
⇒ 
On substituting the values, we get
⇒ 
⇒ 
So that alternative B is the appropriate choice.
