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:
{ - 2, 1 }
Step-by-step explanation:
To determine the values let y = 0, that is
(x + 2)(2x - 2) = 0 ← in standard form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
2x - 2 = 0 ⇒ 2x = 2 ⇒ x = 1
The set of values are { - 2, 1 }
Answer:
Bracket open, y raised to the power of three, bracket close, raised to the power of two
OR
In bracket, y raised to the power of three, bracket close, raised to the power of two
