Assume that from 1930 to 1960, the number of deaths from lead poisoning (per 100,000 people) decreased dramatically and could be modeled by f(x) = -0.0148x? +542x - 49,275, where x is the year. Determine when to the nearest year, this death rate was 75 or less by graphing yf(x) and y = 75 in 1930, 1980, 10 by 10, 200, 25)
OA 1964 or after
OB 1900 or after
OC 1973 or after
OD. 1967 or after

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9

The perimeter of a rectangle is 42 inches. if the width of the rectangle is 6 inches, what is the length

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
