lana66690 [7]

Answer:

The answer to your question is the letter D) 46°

Step-by-step explanation:

Data

length = 25 ft

Opposite side = 18 ft

Angle = Ф

To solve this problem, use trigonometric functions. The trigonometric function that relates the Opposite side and the hypotenuse is sine.

Sin Ф = Opposite side / hypotenuse

Find the root(s) of f (x) = (x + 5)3(x - 9)2(x + 1). -5 with multiplicity 3 5 with multiplicity 3 -9
faust18 [17]

Answer:

  -5, multiplicity 3; +9, multiplicity 2; -1

Step-by-step explanation:

The roots of f(x) are those values of x that make the factors be zero. For a factor of x-a, the root is x=a, because a-a=0. If the factor appears n times, then the root has multiplicity n.

f(x) = (x+5)^3(x-9)^2(x+1) has roots ...

  • -5 with multiplicity 3
  • +9 with multiplicity 2
  • -1
