A patient's HDL, LDL, and triglyceride levels are 62, 77, and 60, respectively. What is the patient's total cholesterol score? S

Len [333]

Answer:

Total cholesterol score is 199

199 is high cholesterol score especially as it very close to 200. The patient should adopt diets that do not include high cholesterol food

Explanation:

a. Firstly, we want to calculate the patient’s total cholesterol score.

To get this, we use a mathematical approach.

Mathematically;

the total cholesterol score = HDL + TDL + Triglyceride = 62 + 77 + 60 = 199

The patient’s total cholesterol score is 199

b. As a doctor, I will advice the patient on the status of these measurements. Using the scale of cholesterol level, a measurement of total cholesterol = 200 represents a high cholesterol level. Since 199 is very close to 200, the patient is at a risk of high cholesterol levels and thus needs a dietary change.

Hi can ya'll pls do my homework lol I'm too lazy. I'll give you brainliest anddd be rlly happy?

Explanation:

1. The radiaton from the X-ray waves can be harmful

2. Lack of resources comes on part of both the provider as well as the patient as the provider may not necessarily have the appropriate equipment or updated technology yet to detect such conditions such as in smaller town hospitals or even the patient may not have the financial or transportation resources in order to obtain these. Another one but while being a little subjective I think could even be a lack of knowledge on both of our parts as well as healthcare providers don't always have all the answers to everything let alone the resources as mentioned earlier or even perhaps the patient doesn't know the earlier signs and symptoms of certain cancers and even more so some cancers are VERY difficult to detect, especially until its too late.

3. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white

4. An X-Ray will be neccesary, ultrasounds exam organs while x-rays examine bones

In 1985 a biologist counted 750 pine trees in a 250 hectare forest. Using similar counting techniques, the biologist counted 1,2

Alisiya [41]

Answer:

Suppose that we have a given function f(x)

The average rate of change of the function between two values x₁ and x₂ is given by:

$r = \frac{f(x_2) - f(x_1)}{x_2 - x_1}$

a) We want to find the average (rate) of change on the size of population from 1985 to 1995.

We have that:

f(1985) = 750

f(1995) = 1500

Then we have:

$r = \frac{1500 - 750}{1995 - 1985} = 750/10 = 75$

This means that the population of trees increases, in average, at a rate of 75 trees per year.

b) What is the density of trees each year that they were counted?

This will be equal to the quotient between the number of trees and the area.

1985: number of trees = 750 pines

area = 250 ha

Then the density is:

D(1985) = (750 pines)/(250 ha) = 3 pines/ha

So 1985, there were 3 pines per hectare.

1990: number of trees = 1250 pines

area = 250 ha

Then the density is:

D(1990) = (1250 pines)/(250 ha) = 5 pines/ha

1995: number of trees = 1500 pines

area = 250 ha

The density is:

D(1995) = (1500 pines)/(250 ha) = 6 pines/ha

3) now we want to get the average change between 1985 and 1995 in the density, this will be:

$r = \frac{D(1995) - D(1885)}{1995 - 1985} = \frac{6 pines/ha - 3pines/ha}{10} = 0.3 pines/ha$

So, on average, each year the number of pines per hectare increases by 0.3
