Answer:

$(3.4)$

Step-by-step explanation:

Our equation is $f(x)=-2(x-3)^2+4$
Now there are 2 ways you can do this, I'll show you the shortcut
If you have an equation like this, just take the value in parenthesis and equate it to zero
$x-3=0.x=3$ is the x of the vertex
Put this back into the equation
$f(x)=-2(x-3)^2+4\\x=3\\f(3)=-2(3-3)^2+4\\f(3)=-2(0)^2+4=4$ this is the y

If the measure of arc DEF is 248°, what is the measure of ∡DEF?

HACTEHA [7]

The figure attached has <DEF which is an inscribed angle. An inscribed angle is an angle with its vertex on the circle which is formed by two intersecting chords. According to formulas, the measurement of arc DF is twice the measurement of ∡DEF. Arc DF is equal to 360-248 or 112. Hence ∡DEF is equal to 56 degrees.
