What is basketball ?

Basketball exists as a team sport in which two teams, most generally of five players each, opposing one another on a rectangular court, contest with the primary objective of shooting a basketball (approximately 9.4 inches (24 cm) in diameter) through the defender's hoop (a basket 18 inches (46 cm) in diameter mounted 10 feet (3.048 m) high to a backboard at each end of the court, while controlling the opposite team from shooting through their hoop. A field goal stands worth two points unless made from behind the three-point line when it stands worth three. After a foul, timed play stops and the player fouled or selected to shoot a technical foul is assigned one, two, or three one-point free throws. The team with the most points at the end of the game wins, but if regulation play passes with the score tied, an additional period of play (overtime) exists mandated.

Hence, The correct option is D The movement of basketball players on a court.

Rocephin® is an antibiotic sometimes used to treat skin infections. In children, the maximum recommended daily dose of this medicine is 75 mg/kg of body mass. Express this dosage in g/lb, using the conversion 1 kg=2.20 lb.

Answers

A daily dose of 75 mg/kg of body mass of Rocephin® is equivalent to 0.034 g/lb of body mass.

In children, the maximum recommended daily dose of this medicine is 75 mg/kg of body mass. First, we will convert this dose to g/kg of body mass using the conversion factor 1 g = 1000 mg.

[tex]\frac{75 mg\ Rocephin}{kg\ body\ mass} \times \frac{1 g\ Rocephin}{1000 mg\ Rocephin} = \frac{0.075 g\ Rocephin }{kg\ body\ mass}[/tex]

Then, we will convert the dose of 0.075 g of Rocephin/kg of body mass to g of Rocephin/lb of body mass using the conversion factor 1 kg = 2.20 lb.

[tex]\frac{0.075 g\ Rocephin }{kg\ body\ mass} \times \frac{1kg\ body\ mass}{2.20lb\ body\ mass} = \frac{0.034 g Rocephin}{lb\ body mass}[/tex]

Why do you think the mass of the carbon atom shown is 12 atomic mass units (amu)?

Answers

Answer:

The mass of Carbon-12 is exactly 12 amu. But, that is not the number that is reported in your periodic table. Carbon as it exists in nature is not all carbon-12. There is some small amount of carbon-13 and even traces of carbon-14 in there. The periodic table reports the average mass of the carbon as it is found in nature, not that of pure carbon-12. The average mass of carbon is slightly heaver than carbon-12, because of the slight amounts of those heaver isotopes of carbon in nature.

A pediatrician uses the model above to estimate the height h of a girl, in inches, in terms of the girl's age a, in years. Based on the model, what is the estimated height of a 2-year-old girl?

Answers

Answer:

h = 34.2 in

Explanation:

h = 3.0a + 28.2

h = height of a girl.

a = age of a girl.

h = 3.0a + 28.2

h = 3.0(2) + 28.2

h = 6 + 28.2

h = 34.2

The estimated height of a 2-year-old girl is 34.2 in.
