How can you identify a linear nonproportional relationship from a table, a graph, and an equation?

1 answer:

3 0

On-proportional linear relationships can be expressed in the form y = mx + b, where b is not 0, m represents the constant rate of change or slope of the line, and b represents the y-intercept. The graph of a non-proportional linear relationship is a straight line that does not pass through the origin.

Which graph shows a function whose inverse is also a function?

expeople1 [14]

Answer:

Step-by-step explanation:

The function whose inverse is also a function would pass the horizontal line test. This means that if you place a horizontal line at any y-level in the graph, the line should only pass through the function one or less times.

A ball is thrown from an initial height of 6 feet with an initial upward velocity of 23ft/s . The ball's height h (in feet) afte

Diano4ka-milaya [45]

There's a lot of extra information here. All you are really concerned with is solving the polynomial for roots. You want t when h = 14. So let's do it:

$14 = 6+23t-16t^2$
$8=23t-16t^2$

Rearranging to make it simpler to put into a quadratic form:
$0 = -16t^2+23t-8$

Now, let's plug it into the quadratic equation:
$\frac{-23+ \sqrt{(23)^2-4(-16)(-8)} }{2(-16)}$
and
$\frac{-23- \sqrt{(23)^2-4(-16)(-8)} }{2(-16)}$

Solving the quadratic gives us:
0.5899 and 0.8476

So, your answer is: h = 14 when t = 0.5899 or t = 0.8476
