A certain species of tree grows an average of 0.5 cm per week. Write an equation for the sequence that represents the weekly height of this tree in centimeters if the measurements begin when the tree is 800 centimeters tall.

Answers

Answer 1

Answer: You would turn this into a function f(x). So the constant rate (or slope) is 0.5, so you start off with f(x)=0.5x. But you know that it starts at 8000, which is your intercept. So your final result is
F(x)= 0.5x +8000

You are going to paint stripes on one wall of your bedroom. the wall is 13.3 feet wide, and you want to paint 14 stripes. about how wide should each stripe be?

Answers

The 14 stripes would be equal to 13.3 feet wide wall.

14 stripes = 13.3 feet

1 stripe = 13.3/14 = 0.95

So each stripe would be 0.95 feet wide.

Hope this helps.

The width of each stripe is 0.95 ft.

What is width?

Width tells us that how wide a thing is, width is the wideness of a thing.

Given that, You are going to paint stripes on one wall of your bedroom. the wall is 13.3 feet wide, and you want to paint 14 stripes.

We know that the width of the wall = 13.3 feet

We also know that the number of stripes to be painted = 14

Width of one stripe = (the width of wall)/(total number of stripe)

Width of one stripe = 13.3/14

Width of one stripe = 0.95 feet

Hence, the width of one stripe would be 0.95 feet

How is 4.3 x 10^-3 the answer to this question? A sample of air from a home is found to contain 6.2 ppm of carbon monoxide. This means that if the total pressure is 695 torr, then the partial pressure of CO is..................4.3 x 10^-3.

Answers

The partial pressure of CO2 is equal to the total pressure * molar fraction of CO2.

To give 4.3 * 10^-3, they are using molar fraction = 6.2 * 10^ - 6

Because, 695 * 6.2-10^-6 = 0.004309 = 4.309 * 10^-3 = 4.3 * 10^-3.

Then the new question is why the molar fraction is consideres to be the same ppm concentration. This is because ppm means parts per million, and in this case, they are considering that the parts are moles (usually it is grams, but it is not the case, given the result).

6.2 ppm = 6.2 / 1,000,000 = 6.2*10^-6, which is the number used above to multiply the total pressure and get the partial pressure of CO2.

If you had not told me that the result was 4.3 * 10^-3, I had assumedthat 6.2 was referred to grams and not moles and I had made a conversionusing the molar masses of the air and the CO2 but, again, this is not the case.

Final answer:

The partial pressure of CO in a home with air containing 6.2 ppm CO, when the total air pressure is 695 torr, can be calculated by (6.2 ÷ 1,000,000) x 695, which equals 4.3 x 10^-3 torr.

Explanation:

The partial pressure of a gas is the individual pressure contribution a single type of gas makes to the overall pressure of a gas mixture. In this case, a sample of air from a home was found to contain 6.2 parts per million (ppm) of carbon monoxide (CO). To calculate the actual pressure of CO in the room, we can use the fact that 1 ppm = 1 part of the substance per 1,000,000 parts of air.

To do so, we need to multiply thetotal pressure of the air, which is 695 torr, by the ratio of the CO to the total volume of the air. That would be: (6.2 ÷ 1,000,000) x 695 = 4.3 x 10-3 torr. Hence, that is how 4.3 x 10-3 is derived as the partial pressure of CO in this context.

The number of milligrams of a certain medicine a veterinarian gives to a dog varies directly with the weight of the dog. If the veterinarian gives a 30-pound dog milligram of the medicine, which equation relates the weight, w, and the dosage, d?

Answers

If you would like to know which equation relates the weight and the dosage, you can find this using the following steps:

30-pound dog ... 1 milligram of the medicine
w pound dog ... d milligram of the medicine

30 * d = 1 * w
30 * d = w

The correct result would be 30 * d = w.
