Answer:
Step-by-step explanation:
First, we can work out 5% of our number, by multiplying it by 0.05
Now, if we add and subtract our 5% calculated from our original number, we can work out the minimum and maximum value that our final answer can be in the range of.
We can see that 
is in the range of valid answers, as:
So, our final answer is:
Divide 83.524 by pi then take half of that answer .
the answer should be 13.29 or 13.3
Answer:
12:6
Step-by-step explanation:
6 times 2 because Lori is six and her cousin is twice her age (hope it helps)
7. x=3 is the midpoint between the roots. The other root is x = 2*3 -(-5) = 11.
8a) f(x) = (x +3)^2 -49. The vertex is (-3, -49). The roots are -10, 4.
8b) y = (x+4)^2 -1. The vertex is (-4, -1). The roots are -5, -3.
8c) f(x) = 2(x +3)^2 -34. The vertex is (-3, -34). The roots are -3±√17.
