Issac tosses a quarter off of a bridge, creating the shape of a parabola. The parabola can be represented by the equation h=-16t
Wittaler [7]

Answer:

c) 18 units

d) 1 second

Step-by-step explanation:

h = -16t² - 4t + 20

c) t = 0.25

h = -16(0.25)² - 4(0.25) + 20

h = 18

d) -16t² - 4t + 20 = 0

4t² + t - 5 = 0

4t² + 5t - 4t - 5 = 0

t(4t + 5) - (4t + 5) = 9

(4t + 5)(t - 1) = 0

t = -1.25, 1

t = 1 second

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
