Answer:

First the epidermis, then the dermis, and then the hypodermis

Explanation:

The skin has three layers, which are:

(1) The epidermis (the outer layer, which we see)

(2) Followed by the dermis, which is immediately below the epidermis.

(3) Lastly the hypodermis, the innermost layer.

When Corey steps on the tack, the tack will pierce through his foot from the outermost to the innermost layer i.e. in (1), (2) and (3) order.

Hence: (d) is correct.

If 2^x=3^y=12^z, show that 1÷z=1÷y+2÷x.....​
Ostrovityanka [42]

Answer:

Proof of \dfrac{1}{z}}=\dfrac{1}{y}+\dfrac{2}{x}  is shown below.

Explanation:

The given equation is

2^x=3^y=12^z

To prove : \dfrac{1}{z}=\dfrac{1}{y}+\dfrac{2}{x}

Proof : Let as assume,

2^x=3^y=12^z=k

2^x=k\Rightarrow 2=k^{\frac{1}{x}}    ...(1)

3^y=k\Rightarrow 3=k^{\frac{1}{y}}      ...(2)

12^z=k\Rightarrow 12=k^{\frac{1}{z}}    ...(3)

We know that

12=2\times 2\times 3

12=(2)^2\times 3

Using (1), (2) and (3), we get

k^{\frac{1}{z}}=(k^{\frac{1}{x}})^2\times k^{\frac{1}{y}}

k^{\frac{1}{z}}=k^{\frac{2}{x}}\times k^{\frac{1}{y}}

k^{\frac{1}{z}}=k^{\frac{2}{x}+\frac{1}{y}}

On comparing both sides, we get

\dfrac{1}{z}}=\dfrac{2}{x}+\dfrac{1}{y}

\dfrac{1}{z}}=\dfrac{1}{y}+\dfrac{2}{x}

Hence proved.

Which would not be an example of techniques used to build physical activity self-efficacy? A. Maintain a physical activity log t
sammy [17]

Answer:

Help identify barriers of physical activity and exercise

Explanation:

From all the options A to D, one of the best techniques to build physical activity self-efficacy is to provide exposure to vicarious experiences. When we see people around us that we ca relate to excelling in their physical activities and exercises, it can stir us up. Other options are also very great techniques which involves doing something. You can only maintain a physical activity log if you are actually exercising and it is good to track your successes as this helps to promote more successes. However, simply identifying barriers of physical activity and exercise is not an option enough to promote self-efficacy. It is not identifying that is the problem, it is finding a solution that matters.
