Question

Help me resolve this equation?
h (t) = -0.6(t-1.5)^2 + 1.35
We are looking for the value of t. h = 1

Answer 1

are you trying to solve
\[-0.6(t-1.5)^2 + 1.35 =1\]?

Answer 2

No, I am trying to find the value of t.

Answer 3

subtract 1.35 from both sides to get
\[h (t) = -0.6(t-1.5)^2 =-.35 \]

Answer 4

yes i see, we are looking for t.

Answer 5

then divide by -.06 to get
\[(t-1.5)^2=\frac{7}{12}\]

Answer 6

so
\[t-1.5=\pm\sqrt{\frac{7}{12}}\]

Answer 7

and finally
\[t=1.5\pm\sqrt{\frac{7}{12}}\]

Answer 8

Thank you! That helped a lot

Answer 9

Answer 10

I have one more question. When you found 1.35, and put it on the other side to get -.35, where did the 1 go? Thanks again
