They should get $7.50, because you multiply the adults by two, then the children by three, and add it all together
Answer:
![m=\frac{-1}{4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1%7D%7B4%7D)
Step-by-step explanation:
A quadratic equation has one root if the discriminant is 0.
That is we need
for this particular question.
Compare the following to find
:
![ax^2+bx+c=0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%3D0)
![my^2+2y-4=0](https://tex.z-dn.net/?f=my%5E2%2B2y-4%3D0)
The variable
is representative of the variable
here.
![a=m](https://tex.z-dn.net/?f=a%3Dm)
![b=2](https://tex.z-dn.net/?f=b%3D2)
![c=-4](https://tex.z-dn.net/?f=c%3D-4)
Plug in into
:
![(2)^2-4(m)(-4)=0](https://tex.z-dn.net/?f=%282%29%5E2-4%28m%29%28-4%29%3D0)
![4+16m=0](https://tex.z-dn.net/?f=4%2B16m%3D0)
Subtract 4 on both sides:
![16m=-4](https://tex.z-dn.net/?f=16m%3D-4)
Divide both sides by 16:
![m=\frac{-4}{16}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-4%7D%7B16%7D)
Reduce:
![m=\frac{-1}{4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1%7D%7B4%7D)
4.5/9. It is technically an improper fraction but it still counts.
Answer:
![\huge\boxed{x>-2\to x\in(-2;\ \infty)}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7Bx%3E-2%5Cto%20x%5Cin%28-2%3B%5C%20%5Cinfty%29%7D)
Step-by-step explanation:
![y=\log(x+2)\\\\\bold{Domain:}\\\\x+2>0\qquad|\text{subtract 2 from both sides}\\\\x+2-2>0-2\\\\x>-2](https://tex.z-dn.net/?f=y%3D%5Clog%28x%2B2%29%5C%5C%5C%5C%5Cbold%7BDomain%3A%7D%5C%5C%5C%5Cx%2B2%3E0%5Cqquad%7C%5Ctext%7Bsubtract%202%20from%20both%20sides%7D%5C%5C%5C%5Cx%2B2-2%3E0-2%5C%5C%5C%5Cx%3E-2)
Answer:
26.376 because the circumference formula is 2*3.14*radius so the radius of the goal would be 9 because radius is half of diameter which is 18 so 2*3.14*9=56.52 and the basketball's radius would be 4.8 and then 2*3.14*4.8 is 30.144 so the answer is 26.376 hope it helps
