A rectangular steel plate expands as it is heated. Find the rate of change of area with respect to temperature T when the width
trapecia [35]

Answer:

The variation rate is 4.07 × 10⁻⁵ cm²/ºC

Step-by-step explanation:

The relationship of the change in length as a function of the temperature, which are given in this problem can be written by the expression for the area of ​​a rectangle

a = L × W

Differentiating both sides,

\frac{da}{dT} = \frac{d(LW)}{dT}

\frac{da}{dT} = W \frac{dL}{dT} + L \frac{dW}{dT}

The values ​​they give us are

\frac{dL}{dT} = 1.1 × 10⁻⁵ cm/ºC

\frac{dW}{dT} = 8.9 × 10⁻⁶ cm/ºC

W = 1.6  cm

L= 2.6 cm

Substituting the values ​​and calculating

\frac{da}{dT} = (1.6 × 1.1 × 10⁻⁵) + (2.6 × 8.9 × 10⁻⁶)

\frac{da}{dT} = (1.76 × 10⁻⁵) + (2.31 × 10⁻⁵)

\frac{da}{dT} =  4.07 × 10⁻⁵ cm²/ºC

The variation rate is 4.07 × 10⁻⁵ cm²/ºC

Theo started to solve the quadratic equation (x 2)2 – 9 = –5. he added 9 to both sides and the resulting equation was (x 2)2 = 4
balu736 [363]

The resulting equation of that step is the square root of  (x + 2)²  is  (x + 2).

<h3>What is the square root function?</h3>

A square root function is defined as a one-to-one function that takes a positive number as an input and returns the square root of the given input number.

From there, it was pretty easy for Theo to find the solutions

to the original equation.

If  (x + 2) = +2 , then  x = 0 .

If  (x + 2) = -2 , then  x = -4

Hence, the resulting equation of that step is the square root of  (x + 2)²  is  (x + 2).
