Consider the quadratic equation: 5x2 + 2x + 1 = 0. 1) which statement is true about the roots of the given quadratic equation? a) 1 real root of multiplicity 2 b) 2 distinct real roots c) 1 complex root and 1 real root eliminate d) 2 complex roots

Hello!

In math, there is always something called the discriminant. This is represented by the equation , when a quadratic = . The discriminant tells you what roots an equation has. A discriminant of over 0 represents 2 real roots, a discriminant of 0 = 1 real root, and a discriminant of <0 is 0 real roots (2 complex roots)

Now, substitute in the values and solve. In this equation, a = 5, b = 2, c = 1.

Therefore, the discriminant is -16. This means that the equation has no real roots, and has 2 complex roots. Therefore, your answer is D.

Hope this helps!

c) yes, because of asa or aas

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
