Solve: h = -16t^2 + 60t + 0. Round to the nearest hundredth.

1 answer

To solve the equation \( h = -16t^2 + 60t + 0 \), we can factor or use the quadratic formula to find the values of \( t \) when \( h = 0 \).

Thus, we need to solve: \[ -16t^2 + 60t = 0 \]

We can factor out \( t \): \[ t(-16t + 60) = 0 \]

Setting each factor to zero gives us:

  1. \( t = 0 \)
  2. \( -16t + 60 = 0 \)

For the second equation: \[ -16t + 60 = 0 \ 16t = 60 \ t = \frac{60}{16} \ t = \frac{15}{4} \ t = 3.75 \]

Thus, the solutions to the equation \( h = 0 \) are: \[ t = 0 \quad \text{and} \quad t = 3.75 \]

Since the initial question asked for the solution to the equation \( h = -16t^2 + 60t + 0 \) with rounding to the nearest hundredth, the roots are:

\[ t = 0.00 \quad \text{and} \quad t = 3.75 \]
