A liquid at temperature 7575F is placed in an oven at temperature 450450. The temperature of the liquid increases at a rate 77 t

hichkok12 [17]

Answer: $\dfrac{dT(t)}{dt}=77\times (450-T)$

Step-by-step explanation:

Given

The temperature of the liquid is $75^{\circ}F$ placed in an oven with temperature of $450^{\circ}F$ .

Initially difference in temperature of the two

$\Delta T=450-75\\\Rightarrow \Delta T=375^{\circ}F$

According to the question

$\Rightarrow \dfrac{dT(t)}{dt}=77\cdot \Delta T\\\\\Rightarrow \dfrac{dT(t)}{dt}=77\times (450-T)\quad [\text{T=75}^{\circ}F\ \text{at t=0}]$

Solve the compound inequality.

aivan3 [116]

Option D:

$x$

Solution:

Given compound inequality:

$6-x>15 \text { or } 2 x-9 \geq 3$

Let us first solve $6-x>15$ .

Subtract 6 from both sides.

$6-x-6>15-6$

$-x>9$

To reverse the inequality multiply by -1 on both sides.

$(-x)(-1)$

$x$

Now solve the next inequality $2 x-9 \geq 3$ .

Add 9 on both sides.

$2 x-9+9 \geq 3+9$

$2 x \geq 12$

Divide by 2 on both sides.

$$\frac{2 x}{2} \geq \frac{12}{2}$

$x \geq 6$

Combine the inequality.

$x$

Option D is the correct answer.

The formula <img src="https://tex.z-dn.net/?f=X%3D%20%5Cfrac%7BD%7D%7B1-h%7D" id="TexFormula1" title="X= \frac{D}{1-h}" alt="X=

Debora [2.8K]

X = D/(1 - h)
1 - h = D/x
h = 1 - D/x

D = 400, X = 4000
h = 1 - 400/4000
h = 1 - 0.1 = 0.9
