Answer is answer
Step-by-step explanation:The number of newly reported crime cases in a county in New York State is shown in
the accompanying table, where x represents the number of years since 2007, and y
represents number of new cases. Write the linear regression equation that represents
this set of data, rounding all coefficients to the nearest hundredth. Using this
equation, find the projected number of new cases for 2016, rounded to the nearest
whole number
Years since 2007 (x) New Cases (y)
0
1156
1
1167
2
1230

1215

1298
M = (y2-y1)/(x2-x1)
= (4-14)/3-1
= -10/2
= -5
Function 1 has a maximum at y = 1
Now we need to find the maximum of Function 2 by completing the square:
-x^2 + 2x - 3
= -(x^2 - 2x) - 3
= -(x - 1)^2 +1 - 3
= -(x - 1)^2 - 2
Therefor the turning point is at (1, -2) and the maximum is at y = -2
-2 < 1, therefor Function 1 has the larger maximum
Answer:
Step-by-step explanation:
a) D/280 = tan(90 - 6)
D = 280tan84 = 2,664 ft
b) D/280 = tan(90 - 16)
D = 280tan74 = 976 ft
ship speed = (2664 - 976) / 43 = 39.2 ft/s
