Rabbit's position vector (r) in the unit vector is 203.5î - 57j and the magnitude and directional angle of vector (r) are 195.35m and 0.004° respectively.
Given
x = 0.3t² + 7.2t + 28
y = 0.22t² - 9.1t +30
At t = 15s
x = 0.3(15)² + 7.2(15) +28 = 203.5
y = 0.22(15)² - 9.1(15) + 30 = -57
The rabbit's position vector (r) in unit vector notation is:
r = 203.5î - 57j
The magnitude of position vector (r)
r = √x² + y²
r = √(203.5)² - (57)² =√38163.25
= 195.35m
The directional angle of position vector (r)
tanθ = y/x = -57/203.5
θ = 
(-57/203.5)
θ = 0.004°
Hence, rabbit's position vector (r) in the unit vector is 203.5î - 57j and the magnitude and directional angle of vector (r) are 195.35m and 0.004° respectively.

Answer:
"I will eat a meat source such as chicken or pork with each meal."
Explanation:
Vitamin B12, or cobalamin, is one of eight B-complex vitamins. It is found only in animal foods (except honey), such as red meats, seafood, fish, eggs and milk, and is responsible for important functions in the body. Vitamin B12 deficiency is difficult to diagnose, but can cause serious conditions such as megaloblastic anemia and pernicious anemia. Specific groups in society, such as non-supplementary vegetarians and vegans and people over 50, are those most vulnerable to vitamin B12 deficiency.
Regarding the customer exposed in the question, the statement "I will eat a meat source such as chicken or pork with each meal." demonstrates that he is well informed and has correctly learned all the claims about vitamin B12.
Answer:
lymphocytes
Explanation:
Lymphocyte is a type of cell that is part of the body's immediate defense, acting against cancer cells and viral infections. Also, these cells are very important in wound healing. Slower healing of an injury is best explained by temporarily reduced lymphocyte production.
The concentration of these cells in the blood depends on the individual's physical condition: in cases of immunodeficiency, the concentration is low (lymphopenia); when there are infections or rejection of transplants, it increases (lymphocytosis). Lymphocyte count is a widely used test for monitoring diseases and infections such as those caused by HIV.
Health insurance doesn’t mean that you must have the Cadillac of plans to cover every health need. Such plans are very expensive. There are other types of plans, such as HMOs, that provide less costly coverage.
Out of the following choices, the best treatment for a virus is is an antibiotic. However, most virus's can't be treated with an antibiotic and will be treated with over the counter remedies.
