Answer:
The standard form of the quadratic equation is x² + 3·x - 4 = 0
Step-by-step explanation:
The standard form of a quadratic equation is a·x² + b·x + c = 0
Given that the expression of the quadratic equation is (x + 4)·(x - 1) = y, we can write the given expression in standard form by expanding, and equating the result to zero as follows;
(x + 4)·(x - 1) = x² - x + 4·x - 4 = x² + 3·x - 4 = 0
The standard form of the quadratic equation is x² + 3·x - 4 = 0
The graph of the equation created with MS Excel is attached
Ok so we know it took 4 hrs and 15 minutes, which is the same as 4.25 hrs so we divide 1114 by 4.25 which is 262.118. The average speed of the plane is 262 mph.
Then we just have to multiply 262 by 1.6 to get the speed in kph. That equals 419.2. That means the average speed was 419 kph. Hope that helps!
a/b=c
you gonna cross multiple.
so, b multiple by c=a
bc=a
then you divide it by c
so the answer will be b=a/c
