Answer:
The equation of the quadratic function shown is;
x^2+ 2x -3
Step-by-step explanation:
Here in this question, we need to know the quadratic equation whose graph was shown.
The key to answering this lies in knowing the roots of the equation.
The roots of the equation are the solution to the quadratic equation and can be seen from the graph at the point where the quadratic equation crosses the x-axis.
The graph crosses the x-axis at two points.
These are at the points x = -3 and x = 1
So what we have are;
x + 3 and x -1
Multiplying both will give us the quadratic equation we are looking for.
(x + 3)(x-1) = x(x -1) + 3(x-1)
= x^2 -x + 3x -3 = x^2 + 2x -3
Answer:
125 m/min
Step-by-step explanation:
Find the rate (speed) as follows:
25 meters
--------------------- = (125/1) meters/min = 125 m/min
(1/5) minute
This is equivalent to about 380 ft/min
I dont know the exact answer but I think you may have to subtract 5 and 3/5 and subtract that answer to 1 and 1/2
