3 pros and 3 cons why jenny should or should not do a paleio diet

Answers

Advantages
The diet is rich in potassium – Eating a lot of fruit and vegetables increases potassium levels, which is important for maintaining a healthy blood pressure and healthy kidney and muscle function.
The fats are healthy – Consuming moderate amounts of unsaturated fats such as those found in nuts, avocado and olive oil gives rise to a healthy lipid profile.
High protein content – Proteins are essential for growth and development of the skin, muscles, bone and cartilage. Adequate amounts of lean protein in the diet contribute to a healthy body composition and a lowered insulin response.
Elimination of processed foods – The diet is comprised of whole foods, which means less salt and sugar is consumed. This improves blood sugar levels and blood pressure and can reduce the risk of cardiovascular disease and diabetes.
Disadvantages
The food portions allowed by the diet exceed the recommended daily allowances s for those foods.
Eliminating entire food groups can mean essential nutrients and vitamins are not included in the diet.
People in the West often obtain their calcium from milk, cheese and yoghurt and those following the paleo diet are at risk of inadequate calcium consumption and therefore low bone and tooth density.
The elimination of whole grains may mean a decreased intake of fiber, which is beneficial to gut health.
The diet does not allow the consumption of legumes, which are highly beneficial to gut health and rich in magnesium, selenium and manganese.
Humans today are not genetically identical to ancestors from the Paleolithic period, as the paleo diet assumes. We have evolved in order to adapt to our changing environment.
The diet does not account for the wide range of foods that were available during the Palaeolithic period and there is inadequate evidence available for it to be established exactly what amount and proportions of foods were eaten during that period.
It is not possible to fully adopt the same diet as people did in the Palaeolithic periods, simply because animals and plants have evolved since then and are different compared to what they would have been 10,000 years ago

a triangle has angles that measure (x+40), (3x +20), and (10x-20) respectively. which of the following terms best describes this triangle? ​

Answers

Answer:

Isoceles

Explanation:

Had it on my test

The term that best describes the given triangle is known as Isosceles. Thus, the correct option for this question is C.

What do you mean by Isosceles triangle?

An Isosceles triangle may be defined as a type of triangle in which two sides have the same length. With respect to the length of the sides, the angles opposite to the two sides correspond to each other and are also always equal.

According to the question,

The angles of a triangle are determined by the following concept:

x+40 + 3x+20 + 10x-20 = 180.

14x + 40 = 180.

14x = 180 - 40 = 140, x = 10.

Now, the angles are 50, 50, and 80.

Two angles are equal which means two sides are definitely equal.

Therefore, an isosceles is a term that best describes the given triangle. Thus, the correct option for this question is C.

For the expression:

(9x^2 + 4y^2 -12xy) / (4y^2 - 9x^2)

Find the domain
Find the domain of the simplified expression

Answers

The domain of an expression is the set of input values the expression can take

The domain of the expression is [tex]y \ne 1.5x[/tex]The domain of the simplified expression is [tex]y \ne -1.5x[/tex]

(a) The domain of the expression

The expression is given as:

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)}[/tex]

Set the denominator to 0, to determine the domain

[tex](4y^2 - 9x^2) = 0[/tex]

Remove brackets

[tex]4y^2 - 9x^2 = 0[/tex]

Add 9x^2 to both sides

[tex]4y^2 = 9x^2[/tex]

Divide both sides by 4

[tex]y^2 = 2.25x^2[/tex]

Take positive square roots of both sides

[tex]y = 1.5x[/tex]

Hence, the domain of the expression is [tex]y \ne 1.5x[/tex]

(b) The domain of the simplified expression

The expression is given as:

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)}[/tex]

Rewrite as:

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{(9x^2 - 12xy+ 4y^2 )}{((2y)^2 - (3x)^2)}[/tex]

Expand the numerator

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{(9x^2 - 6xy - 6xy+ 4y^2 )}{((2y)^2 - (3x)^2)}[/tex]

Factorize the numerator

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{3x(3x - 2y) - 2y(3x- 2y )}{((2y)^2 - (3x)^2)}[/tex]

Factor out 3x - 2y

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{(3x - 2y)(3x- 2y )}{((2y)^2 - (3x)^2)}[/tex]

Express the denominator as a difference of two squares

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{(3x - 2y)(3x- 2y )}{(2y - 3x)(2y + 3x))}[/tex]

Rewrite as:

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{-(2y - 3x)(3x- 2y )}{(2y - 3x)(2y + 3x))}[/tex]

Cancel out the common term

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{-(3x- 2y )}{(2y + 3x)}[/tex]

Set the denominator to 0, to determine the domain

[tex]2y + 3x= 0[/tex]

Subtract 3x from both sides

[tex]2y= -3x[/tex]

Divide both sides by 2

[tex]y= -1.5x[/tex]

Hence, the domain of the simplified expression is [tex]y \ne -1.5x[/tex]
