Width of smaller tv=x. in feet
length of smaller tv =x+1
l of larger= x+1.5
w of larger = x +0.5
area = l x w
area = (x+1.5)(x+ 0.5)
area= x^2 +2x + 0.75
Answer:
Step-by-step explanation:
We need to find the value of expression 
.
Firstly solving the second term as :
Now the above expression becomes,
-3/2 and +3/2 equals 0.
It means that,
Answer:
21.25 m
Step-by-step explanation:
y = Ax² + Bx + C
Set the origin at the middle of the span so that the point (0, 0) is on the curve
0 = A(0)² + B(0) + C means C = 0
The points (200, 85) and (-200, 85) are on the curve
85 = A(200)² + B(200)
85 = A(-200)² + B(-200)
85 - 40000A - B(200) = 85 - 40000A + B(200)
- B(200) = B(200)
-400B = 0
B = 0
85 = A(200)²
A = 85/40000
y = 85x²/40000
y = 85(100)²/40000 = 21.25 m
