Answer:
y=x^2-9x+18
Step-by-step explanation:
If x1=3 and x2=6, then the equation for the zeroes would be (x-3)(x-6)=0, which can then be expanded to x^2-9x+18=0, making the function y=x^2-9x+18

Answer:
D
Step-by-step explanation:
The area of a circle can be found using:
a=πr^2
We know that the radius is 10 meters. Therefore, we can substitute 10 in for r.
a=π*10^2
Evaluate the exponent
a=π*100
Multiply pi and 100
a=314.159265359
Round to the nearest tenth: there is a 5 in the hundreth place, which indicates we round up the 1 in the tenths place to a 2.
a=314.2
The area is 314.2 square meters, or choice D
