A new hospital tracked the number of births during its first 6 months of operation, as shown in the table. Find a quadratic func
UNO [17]
Let    x refers to the Month numbers
And  y refers to Number of births

There is 5 steps to find the quadratic function that models the data.

First step           ⇒ <span>Plot <span>the data pairs (<span>x<span>, <span>y<span>) in a coordinate plane.
                              which are the blue circles in the attached figure

Second step     ⇒ </span></span></span></span></span></span><span>Draw <span>the parabola you think best fits the data.
                             Which is the red function in the attached figure.

</span></span><span><span>Third step         ⇒</span> Estimate <span>the coordinates of three points on the
<span>                             parabola, which are (2, 108), (4, 68), and (6, 75).</span>
                             </span></span><span><span>which are the black squares in the attached figure</span>

Fourth step       ⇒ </span><span>Substitute <span>the coordinates of the points into the<span> model <span>
                            y <span>= <span>ax<span>2 <span>+ <span>bx <span>+ <span>c
<span>                            to obtain a system of three linear equations.</span>

                            4a + 2 b + c = 108   ---------(1)
                            </span></span></span></span></span></span></span></span></span></span></span><span><span>16a + 4 b + c = 68   ---------(2)</span>
                            36a + 6 b + c = 75   ---------(3)   

Fifth step   ⇒ </span><span>Solve <span>the linear system.
                      By using the calculator
                      a = 5.875 , b = -55.25 , c = 195

So, the</span></span><span> quadratic model for the data is ⇒ y = 5.875 x²- 55.25 x + 195
============================================
T</span><span>o predict the number of births for month 8
substitute with x = 8 ⇒  y = </span><span>5.875 * 8²- 55.25 * 8 + 195 = 129</span>

Aleksandr-060686 [28]

Answer:

21 min

Step-by-step explanation:

V = lwh

V = 60(50)(56) = 168000 cu. cm

8 liters = 8000 cu cm

168000/8000 = 21 min.

The slope of the line below is -2. Use the coordinates of the labeled point to find the point-slope equation of the line. (4, -6
r-ruslan [8.4K]

<u>Answer:</u>

The point-slope equation of the line is y = -2x +2 or 2x+y = 2

<u>Solution: </u>

Let us assume that the slope is m and the y intercept of the line is b

Hence, y=m x+b--------- (i)

y intercept means we need to find the value of y when x is 0

Here the line passes through point (4,-6) and slope m = (-2)

Now putting the point (4,-6) in equation (i) we get,

\Rightarrow-6 = m\times4 +b

\Rightarrow-6 = (-2)\times4 +b

\Rightarrow-6 = -8 +b

\Rightarrow-6+8 =b

\Rightarrow b = 2

So, the equation of the line will be will be y = -2x +2 or 2x+y = 2
