The area of a rectangle is <em>L x W</em>. We have to get the value of x first so that we can find the area of the rectangle.

To get the value of x
given:
<span>a. 12 & X
b. X-2 & 16 </span>
solution:
12x (x) = (8-2 ) 16
12x = 16x-32
32 = 16x-- 12x
<u>32 </u> = <u>4x</u>
4 4
8 = x

Checking:

a. 12 & X b. X-2 & 16
Area of a rectangle = L x W Area of a rectangle = L x W
      =12 x 8    = (8-2) 16
Area of a rectangle = 96 = 6 (16)
Area of a rectangle = 96

Newton's law of cooling is:

Mnenie [13.5K]

Answer:

$t = \frac{ln(\frac{21}{59})}{-0.15}=6.887 hr$

So it would takes approximately 6.9 hours to reach 32 F.

Step-by-step explanation:

For this case we have the following differential equationÑ

$\frac{du}{dt}= -k (u-T)$

We can reorder the expression like this:

$\frac{du}{u-T} = -k dt$

We can use the substitution $w = u-T$ and $dw =du$ so then we have:

$\frac{dw}{w} =-k dt$

IF we integrate both sides we got:

$ln |w| = -kt +C$

If we apply exponential in both sides we got:

$w = e^{-kt} *e^c$

And if we replace w = u-T we got:

$u(t)= T + C_1 e^{-kt}$

We can also express the solution in the following terms:

$u(t) = (T_i -T_{amb}) e^{kt} +T_{amb}$

For this case we know that $k =-0.15 hr$ since w ehave a cooloing, $T_{i}= 70 F, T_{amb}=11F$ , we have this model:

$u(t) = (70-11) e^{-0.15t} +11$

And if we want that the temperature would be 32F we can solve for t like this:

$32 = 59 e^{-0.15 t} +11$

$21=59 e^{-0.15 t}$

$\frac{21}{59} = e^{-0.15 t}$

If we apply natural logs on both sides we got:

$ln (\frac{21}{59}) =-0.15 t$

$t = \frac{ln(\frac{21}{59})}{-0.15}=6.887 hr$

So it would takes approximately 6.9 hours to reach 32 F.

How many times longer does it take light from the Sun to reach Neptune than Mercury? Express this number in standard notation. E

stealth61 [152]

9514 1404 393

Answer:

77.6

Step-by-step explanation:

The ratio of light times will be the ratio of distances:

(light time to Neptune) / (light time to Mercury)

= (Neptune distance)/(Mercury distance)

= (27.93×10^8 mi)/(0.3598×10^8 mi) = 27.93/0.3598

≈ 77.6

It takes about 77.6 times as long for light to reach Neptune as it does to reach Mercury.
