Answer:
0.030
Step-by-step explanation:
=> 0.029646
To three dps that there should be only 3 decimals places after rounding off.
So, it becomes
=> 0.030 (Because the digit in ten thousandths place was greater than 5)
La solución del sistema de ecuaciones es igual a (x, y) = (308/47, 42/47).
<h3>¿Cómo resolver un sistema de ecuaciones linear por igualación?</h3>
Los sistemas de ecuaciones basadas en entidades algebraicas se resuelven mediante procedimientos algebraicos. Grosso modo, el método de resolución por igualación consiste en despejar una variable en dos ecuaciones del sistema para eliminarla y reducir el número de ecuaciones <em>lineales</em> y el número de variables.
A continuación, presentamos una aplicación del método de eliminación:






y = 42/47

x = 308/47
La solución del sistema de ecuaciones es igual a (x, y) = (308/47, 42/47).

Answer:

Step-by-step explanation:
We know that the equation that models the height of the ball as a function of time is
.
Where the initial speed is 80 feet.
When the ball lands on the ground, its height will be
.
So to know how long it will take the ball to reach the ground, equal h (t) to zero and solve for t.

To solve this quadratic equation we use the quadratic formula.
For an equation of the form:

The quadratic formula is:

In this case

Then


We take the positive solution
