Answer:
k=10
Step-by-step explanation:
g(x)=2x^2+ kx+18
when x=-2
g(-2)=2 (-2)^2 -2k +18
Since when x is -2, y =6
6=2 (-2)^2 -2k +18
6=18+8-2k
2k=26-6
2k=20
k=10
The answer is C
Radius is 8.2 and circumference is 51.52
Answer:
Because the store claimed to have the best overall prices
Slope = y2-y1 / x2 - x1
= -8-2 / -10-5
= -10 / -15
= 2/3
