Answer:

After 3 seconds

Step-by-step explanation:

Given

$h(t) = -16t^2 + 96t$

Required

Seconds to attain maximum height

The maximum of a quadratic function $y = ax^2 + bx + c$ is calculated using:

$x = -\frac{b}{2a}$

So, we have:

$t = -\frac{b}{2a}$

Where:

$a = -16$ and $b = 96$

So:

$t = -\frac{96}{2 * -16}$

$t = -\frac{96}{-32}$

Cancel out negatives

$t = \frac{96}{32}$

$t = 3$

2x+3y=11<br> Solve for x and y

irga5000 [103]

To solve this equation you have to isolate one variable, first we will solving for x, then for y.

Solving for x

$2x+3y=11$

$2x=11-3y$

$\boxed{\boxed{x=\frac{11}{2}-\frac{3}{2}*y}}$

Solving for y

$2x+3y=11$

$3y=11-2x$

$\boxed{\boxed{y=\frac{11}{3}-\frac{2}{3}*x}}$
