What is the vertex of g(x) = 8x2 - 48x + 65?
O (-3,-7)
O (3.-7)
O (24,-7)
O (-24,-7)

The answer is B (3.-7)

Step-by-step explanation:

If you graph it the vertex is the top of the curve

(3,-7)

Step-by-step explanation:

Just took the quiz and got it right

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

180
