Answer:
62.5 miles per hour
Step-by-step explanation:
Given data
distance= 125m
time= 2 hours
We know that
speed= distance/time
Subsitute
Speed= 125/2
speed= 62.5 miles per hour
5(10)-y=54
50-y=54
-y=54-50
-y=4
y=4/-1
y=-4
hope its help you
The quadratic has one root with multiplicity 2 if the discriminant is 0, which is
(That is, for a quadratic , the discriminant is .)
Set the discriminant equal to 0 and solve for :
Step-by-step explanation:
whenever a complex number is a root of a polynomial with real coefficients, its complex conjugate is also a root of that polynomial. as an example, we'll find the roots of the polynomial..
x^5 - x^4 + x^3 - x^2 - 12x + 12.
the fifth-degree polynomial does indeed have five roots; three real, and two complex.
