A vector makes an angle, θ, with the horizontal. The horizontal and vertical components of the vector will be equal in magnitude if θ is.
A vector has horizontal and vertical components.
The value of [tex]\mathbf{\theta }[/tex] is 45 degrees, when the horizontal and vertical components are equal
Let the magnitude of the vector be H.
So, the horizontal (h) and the vertical components (v) of the vector would be:
[tex]\mathbf{v = Hcos(\theta)}[/tex] --- vertical
[tex]\mathbf{h = Hsin(\theta)}[/tex]
Equate both expressions
[tex]\mathbf{h = v}[/tex]
Substitute values for h and v
[tex]\mathbf{Hcos(\theta) = Hsin(\theta)}[/tex]
Divide both sides by H
[tex]\mathbf{cos(\theta) = sin(\theta)}[/tex]
When [tex]\mathbf{cos(\theta) = sin(\alpha)}[/tex], then
[tex]\mathbf{\theta + \alpha = 90^o}[/tex]
So, we have:
[tex]\mathbf{\theta + \theta = 90^o}[/tex]
[tex]\mathbf{2\theta = 90^o}[/tex]
Divide both sides by 2
[tex]\mathbf{\theta = 45^o}[/tex]
Hence, the value of [tex]\mathbf{\theta }[/tex] is 45 degrees

Pick one of the body parts shown in Sammi's model. How would a disease or injury to this organ affect the process modeled? How would it affect the body as a whole?.
Answer:
The heart, the heart is what makes every moving part working inside our body even though the brain is the one who tells them or gives them signals to work. the heart is what keeps them alive and if the heart takes any kind of negative damage the would not take care of everything it's supposed to. If the heart starts to fail it will effect the blood suply to all your body parts and blood is what carries the oxygen throughout your body and without getting the proper blood or oxygen supply to those certain body parts will have an effect like you couldn't keep warm or cool off, fight infections, or get rid of our own waste products. Without enough blood, we'd weaken and die.
Explanation: That's my answer
The body part that can be picked in the given model is heart. Any injury can affect the bloop supply throughout the body.
What is circulatory system?Blood vessels in the circulatory system transport blood away from and towards the heart. Arteries transport blood away from the heart, while veins transport blood back to the heart.
The heart in the body is analogous to a car's engine in that it pumps oxygen carrying blood cells into all organs, and without these oxygen carrying blood cells, the entire body will stop functioning.
An injury or disease to the heart will have a negative impact on the rate of blood distribution to all parts of the body, which will have a negative impact on the overall wellbeing of the body and will also have a negative impact on the process being modeled.
Thus, the heart is the body part shown here.

Explanation:
About 12 to 24 hours after taking a high carbohydrate meal.
Answer:
About 12 to 24 hours after the last meal, a person's blood sugar level normally varies from 60 to 90 mg per 100 ml of blood, although it may rise to 130 mg per 100 ml after meals high in carbohydrates. That the blood sugar level is maintained within a fairly narrow range, despite uneven intake of sugar, is due to the bodily process called Homeostasis.
