The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to

Zinaida [17]

Answer:

The total length will be "10 units". A further explanation is given below.

Explanation:

The given points are:

R(−2, 4)

S(3, 4)

T(3, −1)

On applying the distance formula,

⇒ $RS=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

⇒ $=\sqrt{(3-(-2))^2+(4-4)^2}$

⇒ $=\sqrt{(3+2)^2+(0)^2}$

⇒ $=\sqrt{25}$

⇒ $=5 \ units$

and,

⇒ $ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

⇒ $=\sqrt{(3-3)^2+(-1-4)^2}$

⇒ $=\sqrt{0+(-5)^2}$

⇒ $=5 \ units$

Now,

The total trail length will be:

= $RS+ST$

= $5+5$

= $10 \ units$

Do abiotic elements interact with biotic elements in an ecosystem?

myrzilka [38]

Answer:

Yes, the abiotic components interact with the biotic components in an ecosystem.

Explanation:

The abiotic components are the non- living components of an ecosystem. The biotic components are the living components of an ecosystem. Abiotic factors such as sunlight, temperature etc directly affect the biotic components.

For example, the light of the sun is an abiotic component which provides energy to the biotic components, plants, to produce food. Soil is also an abiotic component which provides nutrients and water for the plants which are biotic components.

The graph shows the changing levels of hormones during menstruation and ovulation. What is the general trend for hormones after

Vladimir79 [104]

Answer:

Hormone levels generally decrease.

Explanation:

The graph showed that hormone levels after ovulation generally decrease.

The menstrual cycle of women generally have 3 phases which include:

The follicular phase
The ovulatory phase
The luteal phase

The follicular phase is characterized by low levels of oestrogen and progesterone and a slightly high level of follicle stimulating hormone which ensures that follicles within the ovary develop.

The ovulatory phase is characterized by a surge in the luitenizing hormone (which stimulates the release of eggs) and follicle stimulating hormone with a decrease in the level of oestrogen and a gradual increase in the level of progesterone.

The luteal phase is characterized by a general decrease in the levels of luitenizing hormone and follicle stimulating hormone while oestrogen level may remain high.
