For each scenario below, choose the graph that gives the best representation.
kvv77 [185]

The graph that gives the best representation of the scenario is: option 1 (A).

<h3>Graph of Distance vs Time</h3>
  • A typical graph of distance vs time shows the distance covered as against time.
  • If the graph shows a line that slopes upwards, it implies movement from a spot, if it shows an horizontal line, it implies a rest.

The first graph is the correct one that best represents the scenario because it starts at the point of origin (0, 0), which means the bird covers not distance at zero time when it is still at its nest.

As the bird flies, distance increases with time till it stopped at a point to eat.. This is represented by horizontal line, meaning time increased but distance from the nest remains the same.

The upward slope from the spot represents the further distance the bird is flying in search for more food.

Therefore, the graph that gives the best representation of the scenario is: option 1 (A).

What is the slope of the line? Explain how you calculated the slope in the graph going through the points (-6,-3) and (-2,-8).
horsena [70]

Answer:

\frac{-5}{4}

Step-by-step explanation:

Use the slope formula so y2 - y1 / x2 - x1 [the numbers are subscripts]  

So -8 - (-3) / -2 - (-6) so -8+3/-2+6, therefore -5/4

The data above can be modeled by the function f(x) = 0.0425x^2 + 0.07381x - 0.49107 . Using this equation, predict the skid dist
nataly862011 [7]

Answer:

<em>f(50) = 109.44943 feet</em>

Step-by-step explanation:

<u>Modeling</u>

The model of a situation where the skid distance f is measured against the car speed x can be expressed as:

f(x) = 0.0425x^2 + 0.07381x - 0.49107

Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:

f(50) = 0.0425*50^2 + 0.07381*50 - 0.49107

f(50) = 106.25 + 3.6905 - 0.49107

f(50) = 109.44943 feet
