Answer:

Step-by-step explanation:
✔️Finding h using trigonometric ratio:
Reference angle = 60°
Opposite = h
Adjacent = 3
Thus:

(tan 60 = √3)
Multiply both sides by 3
✔️Finding c using trigonometric ratio:
Reference angle = 45°
Hypotenuse = 8
Adjacent = c
Thus:

(cos 45 = √2/2)
Multiply both sides by 8



Answer: Option B.
Step-by-step explanation:
Given the polynomial:

Observe that
and
are perfect squares. Then, you can rewrite the polynomial in this form:

You can identify that:

Then, we can check if 

Since
, the polynomial
<em>IS NOT </em>a perfect square trinomial of the form 
Answer:
Relative minima at
, and relative maxima DNE.
Step-by-step explanation:
The given function is f(x) = x (x + 7) ...... (1)
We have to calculate the relative maxima and relative minima at point (x, y).
Rearranging the function given above we get.
⇒
Now, this is an equation of parabola having vertex at
and the axis is parallel to positive Y-axis.
Therefore, the function(1) has a relative minima at
, and the relative maxima DNE. (Answer)
