If the recommended adult dosage for a drug is D (in mg), then to determine the appropriate dosage c for a child of age a, pharmacists use the equationc = 0.0417D(a + 1). Suppose the dosage for an adult is 300 mg. (a) Find the slope. What does it represent? O the maximum dosage for an adult O the increase in dosage for each one-year increase in the child's age O the difference between an adult's dosage and a newborn's dosage O the maximum difference between an adult's dosage and a newborn's dosage O the increase in dosage for each one-month increase in the child's age (b) What is the dosage for a newborn? mg
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
