Length of bridge = 53 meters
Length changes expected due to changes in temperature = expansion or contraction by 21 millimeters (or 0.021 meters)
Let length of bridge at any given time be 'a'
As an absolute value equation, the situation can be expressed as:
⇒ |a-53| < 0.021
Solving the equation
⇒ -0.021 < a-53 < 0.021
⇒ 53 - 0.021 < a < 53 + 0.021
⇒ 52.979 < a < 53.021
Hence, the minimum length of the bridge can be 52.979 meters and the maximum length of the bridge can be 53.021 meters.
Answer:
Step-by-step explanation:
g(2)=2.2*(-5)
g(3)=2.2*(-5)^2
........................
g(n)=2.2*(-5)^(n-1)
If you divide $12.91 by .48, that'll give you 26.89583333... So rounding that brings you to $26.90
The answer is they cannot be divided
