X/6.2=-2.1
multiply both sides by 6.2
x=-13.02
B. are parallel.
<span>Line m is drawn so that it is perpendicular to two distinct planes, Q and R. Therefore, planes Q and R are parallel.
Since it doesn't state that two planes intersect with each other, it is safe to assume that only line m is their connection. The planes are parallel with each other. </span>
Here you go.. hope this helps
Answer: 50.84%
Step-by-step explanation:
(89-59) /59 = 0.5084/100 = 50.84%
Solve for the x-max or h :\
![-b/(2a)=-8/(2*-2)=2=k](https://tex.z-dn.net/?f=-b%2F%282a%29%3D-8%2F%282%2A-2%29%3D2%3Dk)
plug it in to equation to get k:/
![y(2)=-2(2)^2+8(2)+3](https://tex.z-dn.net/?f=y%282%29%3D-2%282%29%5E2%2B8%282%29%2B3)
-8+16+3=11=k
![y=a(x-2)^2+11 ](https://tex.z-dn.net/?f=y%3Da%28x-2%29%5E2%2B11%0A)
solve for a by pluging (0,0)
then a= -11/4
