The vertex form:
The axis of symetry is x = h.
We have
Substitute:
<h3>Answer: x = -3</h3>
Answer: Option D.
Step-by-step explanation:
To solve this exercise you must keep on mind the Angle at the Center Theorem.
According to the Angle at the Center Theorem, an inscribed angle is half of the central angle.
Therefore, given in the inscribed angle m∠BAC=35°, you can calculate the central angle m∠EFD as following:
- Solve for EFD.
- When you substitute values. you obtain:
The length of the fencing is 62.4 feet.
The width of the fencing is 17.6 feet.
Given,
The measurement of the Christmas garland = 160 feet
The width of the fencing = w
The length of the fencing, l = 4w - 8
We have to find the length and width of the fencing.
Here,
Perimeter can be taken as 160. Because garland will cover the entire fencing.
Perimeter = 2(l + w)
160 = 2(4w - 8 + w)
160 = 2(5w - 8)
160/2 = 5w - 8
80 + 8 = 5w
88/5 = w
width = 17.6 feet
Now,
l = 4w - 8
l = 4 × 17.6 - 8
l = 70.4 - 8
length = 62.4 feet
That is,
The length of the fencing is 62.4 feet.
The width of the fencing is 17.6 feet.

The answer is: "64 cubic inches" ; or, write as: "64 in³ " .
_______________________________________________________
Explanation:
V = L * w * h ;
= (4 inches) * (4 inches) * (4 inches) ;
(since a "cube" has the same length, width, and height)
= (4*4*4) inches * inches * inches) ;
= 16 * 4 * inches³ ;
= 64 inches³ ; or, write as: "64 in³ " ; or, write as: "64 cubic inches" .
