You would round the hundreds.
but it depends what numbers there are of population like if you get into thousands round by thousand hundreds equals round by hundreds.
The given quadratic equation gives the parameters of the shape of the
graph of the equation.
- The graph that is most likely associated with the model is; <u>graph B</u>
Reasons:
The given function is <u>n(t) = -2.82·t² + 25.74·t + 60.87</u>
by analyzing the above function, we have;
At t = 0
n(0) = -2.82 × 0² + 25.74 × 0 + 60.87 = 60.87
- The x-coordinate of the maximum point is given by

Which gives;

The maximum value of the function is therefore;
n(4.564) = -2.82 × 4.564² + 25.74 × 4.564 + 60.87 ≈ 119.61
The characteristics of the equation are;
Initial value of equation = 60.87
t-coordinate of the maximum point, t ≈ 4.564
Maximum value of the of the function = 119.61
By comparing with the given graphs, we have;
Therefore, the graph that will most likely be associated with the model is; <u>graph </u><u><em>B</em></u>.

Answer: x = the quantity of 5 plus or minus the square root of 29 all over 2
Step-by-step explanation:
The given quadratic equation is expressed as
x² - 5x - 1 = 0
The equation is already in the standard form of ax² + bx + c
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the given quadratic equation,
a = 1
b = - 5
c = - 1
Therefore,
x = [- - 5 ± √(- 5² - 4 × 1 × - 1)]/2 × 1
x = [5 ± √(25- - 4)]/2
x = [5 ± √29]/ 2
x = ( 5 + √29)/- 2 or x = (5 - √29)/2
