I'm assuming that we're looking for the angle of that symbol.

${cos}^{ - 1} = \frac{adj}{hyp} = \frac{4.4}{11}$

$= 66.42182152 \: degrees$

round as you wish.

F(x) = -4x2 + 4x – 4<br> Find f(3)

ValentinkaMS [17]

F(3) occurs when x =3. So lets plug 3 into our equation.

$f(3) = -4(3)^2 + 4(3)-4\\f(3) = -4(9) + 12- 4\\f(3) = -36 + 12- 4\\f(3)= -28$

F(3) = -28

I hope this helps! :)

What is the measure in degrees of 8x if one angle is already 7x and 44.4 degrees?

Julli [10]

7x+8x+44.4=180

15x=44.4=180

15x=135.6

x=9.04°

so 8x=72.32° and the 7x is 63.28°
