Well it would actually be 7.2 inches per each piece
The coordinates of the vertex are (h,k) so we can write:-
f(x) = a(x -2)^2 - 4
now when f(x) = -7 x = 1 so:-
-7 = a(1-2)^2 - 4
-7 = a - 4
a = -3
so the vertex formula is
f(x) = -3(x - 2)^2 - 4
standard form:-
f(x) = -3(x^2 - 4x + 4) - 4
= -3x^2 + 12x - 16
Answer:
Step-by-step explanation:
The area of the equilateral triangle is
Answer:
x = 88.463°
Step-by-step explanation:
We are given a trigonometric equation and we need to find out the value of x. The angle x lies between 0° and 360° . That is ,
<u>Given</u><u> </u><u>trigonometric</u><u> equation</u><u> </u><u>:</u><u>-</u><u> </u>
Subtracting 1 both sides , we have ,
Divide both sides by 5 ,
This equation can be written as ,
