Answer:
Step-by-step explanation: There are 12 colours on a spinner,
Probability of red,orange, blue or green = 1/12×4 =4/12
=1/3
Probability of red,blue, orange or green= 1/12×4=1/3
Probability of not red= 1-1/12
=11/12

Answer:
A
Step-by-step explanation:
![h(t)-j(t)=t^{\frac{2}{3}}-9-[3t+5t^{\frac{2}{3}}]\\\\=t^{\frac{2}{3}}-9-3t-5t^{\frac{2}{3}}\\\\=t^{\frac{2}{3}}-5t^{\frac{2}{3}}-3t-9\\\\=[1-5]*t^{\frac{2}{3}}-3t-9\\\\=-4t^{\frac{2}{3}}-3t-9](https://tex.z-dn.net/?f=h%28t%29-j%28t%29%3Dt%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-9-%5B3t%2B5t%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%5D%5C%5C%5C%5C%3Dt%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-9-3t-5t%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%5C%5C%5C%5C%3Dt%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-5t%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-3t-9%5C%5C%5C%5C%3D%5B1-5%5D%2At%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-3t-9%5C%5C%5C%5C%3D-4t%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-3t-9)
I didn't round by the answer would be 115.575042 miles per second.
We have that

Let y be the first root, then y - 6 will be the second one. Since both roots make the quadratic equation equal to 0, we have that:

Solve for y:

Plug in y = 5/2 into original quadratic equation and solve for c:

So, the answer is
c = -35/4
