Answer:

theta =36.45268177

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj/ hyp

cos theta = 74/92

Taking the inverse cos of each side

cos^-1 ( cos theta) = cos^-1 (74/92)

theta =36.45268177

F(x)=-5x+2 and g(x)=1/2x+4 find f(g(12))

skad [1K]

Answer:

- 48

Step-by-step explanation:

If you want to learn more about this concept, it's called composition of functions.

First, you plug in g(x) as if it were x into f(x).

f(g(x))= -5 (1/2x + 4) + 2

= -5/2x - 20 + 2

= -5/2x - 18

Then, plug in the value given, as x.

= -5/2 (12) - 18

= -30 - 18

= - 48

I hope this helped!

Aleks [24]

$$(a+b)(\frac{1}{a}+\frac{1}{b}) \ \textgreater \ or = 4$
\\
1+a/b+b/a + 1 \geq 4
$ $$(a+b)(\frac{1}{a}+\frac{1}{b}) \ \textgreater \ or = 4$
