Answer 1
Answer:

Answer:

Step-by-step explanation:

The straight, black, dashed line does not resemble the actual (green) line at all, and so it is pointless to compare slopes and y-intercepts here.

However, the pattern of black dots, which represent the measurements obtained through the experiment, do exhibit characteristics comparable to the solid green line.  The green line has been drawn so that it is roughly in the middle of the dot pattern, which in turn indicates that the slope of this pattern is close to that of the green line.  Because this pattern and the green line have similar positive slopes, we can say that the pattern and the line are positively linearly coordinated.  The correlation coefficient is in the range 0.8 - 1.0, which is considered to be a "moderate positive correlation."

Step-by-step explanation:

A catapult launches a boulder with an upward velocity of 112 ft/s. The height of the Boulder, h, in feet after t seconds is given by te function h=-16t^2+112t+30. How long does it take the Boulder to reach its maximum height? What is the Boulder's maximum height ? Round to the nearest hundredth , if necessary . Please , help . I am really stuck here

Answers

Answer:

 Boulder's maximum height is 226 ft.

 It take 3.5 seconds the Boulder to reach its maximum height.

Step-by-step explanation:

Given :  

A catapult launches a boulder with an upward velocity of 112 ft/s.  

The height of the Boulder, h, in feet  

After t seconds is given by the function :


h = -16t^(2) +112t+30     --(a)

A quadratic function can be graphed using a table of values. The graph creates a parabola.


If the coefficient of the squared term is positive then the parabola opens up and The vertex of this parabola is known as the minimum point.


If the coefficient of the squared term is negative then the parabola opens down and The vertex of this parabola is known as the maximum point.


Now we will use vertex formula to calculate t

When f(x)= ax^(2) +bx+c

then vertex will be

x=(-b)/(2a)

Now consider the given function:

h = -16t^(2) +112t+30


where a = -16

b=112

so using vertex formula :

t=(-112)/(2*(-16))

t=3.5

Thus,  it take 3.5 seconds the Boulder to reach its maximum height.

Now to calculate the Boulder's maximum height . Put value of t = 3.5 in given function (a)

h = -16(3.5)^(2) +112(3.5)+30  

h = -196 +392+30  

h = 226  

Thus,  Boulder's maximum height is 226 ft.
Well we first need to do the math problem 

-b/2a = -112/2(16) = 3.5 s t= 3.5s h = -16t^2 + 112t + 30 h = -16(3.5)^2 +122(3.5) +30 h = 226

adjust the windows to y=300

3.5 s; 226 ft
