Step-by-step explanation:

There are 12 in a dozen, so each egg would cost $1.56.

Now, you must multiply $1.56 by 12. Now you can find the answer from here. Hope this helps!

Length = 4 + x Width = x Height = x2 + 1 What is the base area of Box 3?

Simora [160]

Answer:

Base area of box = $x^2 +4$

Step-by-step explanation:

$Length = 4+x$

$Width = x$

$Height = x^2 + 1$

Base area of a rectangular box is a rectangle

Area of a rectangle (base area)= length times width

$Length = 4+x$

$Width = x$

Base area = $(4+x) \cdot x$

Multiply x inside the parenthesis

Base area of box = $4x +x^2$

Using Newton's Law of Cooling. You are a medical examiner called to an abandoned house in which a dead body has been discovered.

Artyom0805 [142]

A) The differential equation comes from the fact that the rate of temperature change is proportional to the difference in temperatures.
$\frac{dT}{dt} = \alpha(T -52)$

B) Find general solution by separating variables and integrating $\int\frac{dT}{T-52} = \alpha \int dt \\ ln (T-52) = \alpha t + C \\ T = C e^{\alpha t} +52$ :

C) Initial condition is t=0, T = 87
$87 = C +52 \\ C = 35$

D) Total time elapsed is 10 minutes, new temperature is 84
$84 = 35 e^{10\alpha} +52$
solve for alpha
$e^{10\alpha} =\frac{32}{35} \\ \alpha = \frac{ln(32/35)}{10} \\ \alpha = -.00896$

E) Temperature function is:
$T = 35 e^{-.00896 t} +52$
solving for t
$t = \frac{ln (\frac{T-52}{35})}{-.00896}$
Plug in T = 98.6
$t = -31.95$

This is approximately 32 minutes before he arrived or about 1:20 AM
