What is the zero of the function?
neonofarm [45]

Answer:

To find the  x -intercept, set  y=0 .

Therefore, the  x -intercept is  (−4,0) . To find the  y -intercept, set  x=0 .

−3x+2y↓−3(0)+2y2yy=12=12=12=6Tofindthey−intercept,setx=0.  

Step-by-step explanation:

To find the  x - and  y -intercepts algebraically, use the fact that all  x -intercepts have a  y -value of zero and all  y -intercepts have an  x -value of zero. To find the  y -intercept, set  x=0  and determine the corresponding  y -value. Similarly, to find the  x -intercept, set  y=0  and determine the corresponding  x -value.

A rocket is launched from a tower. The height of the rocket, why in feet is related to the time after launch, X and seconds, by
Maru [420]

Given:

Consider the height of the rocket, in feet after x seconds of launch is

y=-16x^2+152x+74

To find:

The time at which the rocket will reach its max, to the nearest 100th of a second.

Solution:

We have,

y=-16x^2+152x+74

It is a quadratic polynomial with negative leading coefficient. So, it is a downward parabola.

Vertex of a downward parabola is the point of maxima.

To find the time at which the rocket will reach its max, we need to find the x-coordinate of the vertex.

If a quadratic function is f(x)=ax^2+bx+c, then the vertex is

Vertex=\left(-\dfrac{b}{2a},f\left(-\dfrac{b}{2a}\right)\right)

Here, a=-16,b=152,c=74.

So,

-\dfrac{b}{2a}=-\dfrac{152}{2(-16)}

-\dfrac{b}{2a}=-\dfrac{152}{-32}

-\dfrac{b}{2a}=4.75

So, x-coordinate of the vertex is 4.75.

Therefore, the rocket will reach its max at 4.75 second.
