Answer:

The value of g(f(3)) = 2

Step-by-step explanation:

We are given:

f(x)=2x

g(x) = x-4

And we need to find g(f(3))

First we need to find g(f(x))

by putting the value of f(x) into g(x) i.e put x = 2x

g(x)=x-4\\g(f(x))=2x-4

Now, we need to find g(f(3)) by putting x = 3 in g(f(x))

g(f(x))=2x-4\\Put\: x=3\\g(f(3))=2(3)-4\\g(f(3))=6-4\\g(f(3))=2

So, the value of g(f(3)) = 2

Find in the triangle. Round to the nearest degree.<br> a.<br> 45°<br> C. 60°<br> b. 59°<br> d. 42°
aleksklad [387]

Answer:

Theta = 59 degrees

Step-by-step explanation:

Here, we want to get the value of the marked angle

To do this, we use the appropriate trigonometric ratio

From what we have,

The side 42 ft is adjacent the angle given

The side facing the right angle is 82 ft

The trigonometric ratio that connects the adjacent and the hypotenuse is cosine. It is the ratio of the adjacent to the hypotenuse

Cos theta = 42/82

theta = cos^-1 0.5122

theta= 59.189

To the nearest degrees, this is 59 degrees
