Question

Find the vertex
h(t) = 1/3t^2 - 2t + 8

Answer 1

\[\huge\rm \frac{ -b }{ 2a }\]
formula to find vertex

Answer 2

I did that and got 3.03,4.97 which is wrong

Answer 3

A is what b is what ?

Answer 4

a is 1/3 and b is -2

Answer 5

which becomes positive 2/2(1/3)

Answer 6

okay right so how would you solve denominator ?

Answer 7

2 times 1/3= ?

Answer 8

2/1 * 1/3 = 2/3 or 0.67

Answer 9

then I know I'm supposed to plug it into the equation I just for some reason keep getting the answer wrong

Answer 10

\[\huge\rm \frac{ 2 }{ \frac{ 2 }{ 3 } }\]
change division to multiplication by flipping fraction which is at the denominator for example \[\huge\rm \frac{ \frac{ x }{ y} }{\frac{ a }{ b } } = \frac{ x }{ y } \times \frac{ b }{ a }\]
