Answer:

Choice B.  6 km.

Step-by-step explanation:

We see this is a right triangle.

The height of this right triangle is 3 km and the angle adjacent to the height leg of the triangle is  (90 - 26 ) degrees = 64 degrees.

We want the distance d which is the leg opposite  64 degrees.

tan 64 = d / 3 km  ;

d = 3 * tan 64 =  3 * 2.0503038  km  = 6.1509 km

lukranit [14]
Identify and sum up the x^2 terms:  Result:  3x^2
Next, ident. and sum up the x terms:  Result:  (1/3  +  2) = (7/3)x
Last, ident. and sum up the const. terms:  Result:  -2 - 6 = -8

The sum of these two functions is 3x^2 + (7/3)x - 8.

Write an explicit formula for the arithmetic sequence whose common difference is -18
drek231 [11]

Let the first term be a(0).  Then the formula for a(n) is a(0)-18(n-1).

Check:  What's the first term?  Let n = 1:  a(1) = a(0)-18(1-1) = a(0) (correct)

What's the second term?    Let -n =2:  a(2) = a(0)-18(2-1) = a(0) - 18

and so on.
