9) Which of the following describes the roots of the polynomial function f(x) = (x - 2)(x + 1)(x – 5)2 A) -2 with multiplicity 2, 1 with multiplicity 1, and -5 with multiplicity 2
B) -2 with multiplicity 3,-1 with multiplicity 2, and -5 with multiplicity 4
C) 2 with multiplicity 3,-1 with multiplicity 1, and 5 with multiplicity 2
D) 2 with multiplicity 2, 1 with multiplicity 2, and 5 with multiplicity 4

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

x + 4/7

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
