Answer: -4.8
Step-by-step explanation:
Factor: -2
-0.3, 0.6, -1.2, 2.4,
-0.3*(-2) = 0.6
0.6*(-2) = -1.2
-1.2*(-2) = 2.4
2.4*(-2) = -4.8
Answer:
1 in : 50 mi . . . or . . . 1 : 3,168,000
Step-by-step explanation:
Dividing the areas by 10, you get 1 square inch corresponding to 2500 square miles. Those areas are equivalent to 1 inch square and 50 miles square. Hence the scale factor is 1 inch : 50 miles.
Sometimes map scales are expressed as a dimensionless ratio. The number of inches in 50 miles is
... (50 mi)×(5280 ft/mi)×(12 in/ft) = 3,168,000 in
so, the map scale can be expressed as 1 : 3,168,000.
Answer:
8 + k² - 6 > 8(k + 2) - 4k when k = 7
Step-by-step explanation:
8 + k² - 6 = 8 + 7² - 6 = 51
8(k + 2) - 4k = 8(7 + 2) - 4(7) = 8(9) - 28 = 44
8 + k² - 6 > 8(k + 2) - 4k when k = 7
Answer:
B
Step-by-step explanation:
The retrospective or historic cohort story, is a longitudinal cohort story that considers a particular set of individuals that share the same exposure factor to ascertain its influence in the developments of an occurrence, which are compared with the other set or cohort which were not exposed to the same factors.
Retrospective studies have existed about the same time as prospective studies, hence their names.
