I NEED HELP WITH THIS PRE CALC WORKSHEET, DUE TOMORROW!
nalin [4]

Answer:

1011.05

Step-by-step explanation:

Let's use 3 as an example.

The angle of depression is the one directly under the ballon.

You also know that the 53 degree angle is part of a 90 degree angle.

so the angle inside the triangle directly under the balloon is 37 degrees.

You know the angle and you know the side from the balloon to the ground is 1680.  This is the hypotenuse of the triangle.

So which trig function could you use to determine how high the balloon is from the ground?

SOH CAH TOA

cos 37 = a/1680

a = 1341.71

The explicit rule for a sequence is an=9(−5)n−1 .
SpyIntel [72]
Explicit rule is a(n) = 9*(-5)^(n-1)

The recursive rule is a(n) = -5*a(n-1); a(1) = 9

The first term is 9. Each new term is found by multiplying the previous term by -5

We can see this when we raise -5 to a whole number power. Eg: 9(-5)^3 = 9*(-5)*(-5)*(-5)
