Answer:
t<2
Step-by-step explanation:
If <a=90 or <b=90 or < c=90 the triangle is right
if one of the angles is > 90 the triangle is obtuse
if all the angles are < 90 the triangle is acute
The image of (0,6) after a reflection over the y-axis is (0, 6)
<h3>How to determine the image of (0,6) after a reflection over the y-axis?</h3>
The point is given as:
(0, 6)
The rule of reflection is given as:
Reflection over the y-axis
The rule of reflection over the y-axis is represented as:
(x, y) = (-x, y)
So, we have:
(0, 6) = (-0, 6)
Evaluate the expression
(0, 6) = (0, 6)
Hence, the image of (0,6) after a reflection over the y-axis is (0, 6)

Given : g(x) = 
and h(x)=2x-8.
Let us find g*h(x) function now.
g*h(x) = g(x) * h(x) = 
Or g*h(x) =(2x-8).
He have square root(x-4) in composite function f*h(x).
So, we need to find the domain, we need to check for that values of x's, square root(x-4) would be defined.
Square roots are undefined for negative values.
Therefore, we can setup an inequality for it's domain x-4≥0.
Adding 4 on both sides, we get
x-4+4≥0+4.
x≥4.
Therefore, Domain is all values greater than or equal to 4.
But, restrictions would be all values less than 4 (because less than 4 would give a negative number inside square root).
