Air pressure may be represented as a function of height (in meters) above the

denis-greek [22]

Answer: OPTION C.

Step-by-step explanation:

<h3> The complete exercise is: "Air pressure may be represented as a function of height (in meters) above the surface of the Earth, as shown below:</h3><h3> $P(h) =P_0e^{-0.00012h}$ </h3><h3> In this function $P_o$ is the air pressure at the surface of the earth, and $h$ is the height above the surface of the Earth, measured in meters. At what height will the air pressure equal 50% of the air pressure at the surface of the Earth"</h3><h3></h3>

Given the following function:

$P(h) =P_0e^{-0.00012h}$

In order to calculate at what height the air pressure will be equal 50% of the air pressure at the surface of the Earth, you can follow these steps:

1. You need to substitute $P(h)=0.5P_o$ into the function:

$0.5P_o=P_0e^{-0.00012h}$

2. Finally, you must solve for $h$ .

Remember the following property of logarithms:

$ln(b)^a=a*ln(b)\\\\ln(e)=1$

Then, you get this result:

$0.5P_o=\frac{P_o}{e^{0.00012h}}\\\\(0.5P_o)(e^{0.00012h})=P_o\\\\e^{0.00012h}=\frac{P_o}{0.5P_o}\\\\ln(e)^{0.00012h}=ln(2)\\\\0.00012h*1=ln(2)\\\\h=\frac{ln(2)}{0.00012}\\\\h=5576.2$

What is the height of a cone if the volume is 1/18 and the radios is 2/3

nika2105 [10]

Volume of cone = 1/3 × pi × radius squared × height

1 / 18 = 1 / 3 × 3.142 × 2/3 squared × height
1/18 = 1/3 × 3.142 × 4/9 × height
height = 1/18 ÷ 0.4655
height = 0.119

The formula p=8n-30 gives the profit p when a number of items n are each sold at $8 and expenses totaling $30 are subtracted

irinina [24]

A:
p = 8n - 30
170.00 = 8n - 30 add 30 to each side
200.00 = 8n divide by 8
25 = n 25 items were bought.

B:
The profite would decrese

8(25) - 40
200 - 40
160 original was 170 but it decreased by 10$

hope this helped :)
