Answer:

4.2 ft

Step-by-step explanation:

Reference angle = 77°

Opposite side = DE = x

Hypotenuse = CD = 4.3 ft

Apply the trigonometric function of sine. Thus:

Sin 77 = opp/hyp

Sin 77 = x/4.3

Multiply both sides by 4.3

4.3 × sin 77 = x

x = 4.2 ft (nearest tenth)

Use the domain and range of each of the following relations to determine which is a function.

Setler79 [48]

Answer:

A) Not a function

B) Function

C) Function

D) Not a function

Step-by-step explanation:

If the relation has two of the same x-values (that equal different y-values), it is not a function. In other words, if each input value leads to only one output value, classify the relation as a function.

{(-4,3), (-2,-1), (-4,8)} = Not a function

{-4, 3), (-2.-1), (-7, 8)} = Function

{-4,-2,-7, 7} = Function (I think?)

{-4,3). (-2, -1). (-2, -8), (-7,8)}= Not a function

Evaluate f(4) for the function f(x)=3x-5 A.12 B.7 C.9 D.17

suter [353]

the answer is b.7

Step-by-step explanation:

because you have to plug in the f(4) to the equation like this

f(4)=3(4)-5

and then multiple 3x4 which is 12 then subtract 12 and 5 and you get 7.
