Hello : 
<span>Y=-4x²-8x-13
   = -4(x²+2x) -13
   = -4 ((x² +2x+1)-1) -13
   = -4 (x+1)² +4 -13
</span>Y=   -4 (x+1)² -9
<span>the vertex is : (-1 , -9)

Inside a toy truck, there is a gear that rotates to (3, −8) when the steering wheel is turned to the left. What is the sine valu
Marianna [84]
This is the the concept of trigonometry, to get the sine value of the the function given we shall proceed as follows;
Using Pythagorean theorem, the hypotenuse of the triangle will be found as follows;
The side length will be 8 units since the y-coordinate is -8
The side width will be 3 units since the x- coordinate is 3  
c^2=a^2+b^2
c^2=(3)^2+(-8)^2
c^2=9+64
c^2=73
c=sqrt(73)

Therefore the sine value will be:
sin x=3/sqrt(73)
multiply both numerator and denominator by sqrt(73) we get:
sin x=(3√73)/73

Therefore the answer is A]
