Consider the trinomial 5x^2-2x-3.

1. Find the discriminant:

D=b^2-4ac=(-2)^2-4\cdot 5\cdot (-3)=4+60=64,\\ \\\sqrt{D}=8>0.

2. Find the roots of given trinomial:

x_{1,2}=\dfrac{-b\pm \sqrt{D}}{2a}=\dfrac{2\pm 8}{2\cdot 5}=1,-0.6.

3. Conclusion: given trinomial has two different real roots.

A motor scooter travels 20 mi in the same time that a bicycle covers 8
melamori03 [73]
The scooter is 20 miles per hour and the bicycle is 8 miles per hour. Because twice the rate of the bicycle is sixteen miles then the scooter minus 16 is four as in the four miles per hour mentioned above, so its only one hour then we divide 20 and 8 both seperatly by one and those are your answers

What is a situation in which a polynomial model might make sense, and why?
ololo11 [35]

Answer and Step-by-step explanation:

Polynomial models are an excellent implementation for determining which input element reaction and their direction. These are also the most common models used for the scanning of designed experiments. It defines as:

Z = a0 + a1x1 + a2x2 + a11x12 + a22x22+ a12x1x2 + Є

It is a quadratic (second-order) polynomial model for two variables.

The single x terms are the main effect. The squared terms are quadratic effects. These are used to model curvature in the response surface. The product terms are used to model the interaction between explanatory variables where Є is an unobserved random error.

A polynomial term, quadratic or cubic, turns the linear regression model into a curve. Because x is squared or cubed, but the beta coefficient is a linear model.

In general, we can model the expected value of y as nth order polynomial, the general polynomial model is:

Y = B0 + B1x1 + B2x2 + B3x3 + … +

These models are all linear since the function is linear in terms of the new perimeter. Therefore least-squares analysis, polynomial regression can be addressed entirely using multiple regression

A postcard in the shape of a parallelogram has an area of 12in^2. What are two possible lengths of bases and heights for the pos
Tpy6a [65]

A postcard is in the shape of a parallelogram. A parallelogram  is a quadrilateral with two pair of parallel sides, opposite sides and opposite angles are equal.

Since, the postcard has an area of 12 square inches.

Since, area of parallelogram = base \times height

As area of parallelogram is 12, it means that the product of base and height is 12 square inches.

So, the possible dimensions of postcard are 3 inches and 4 inches and 2 inches and 6 inches.

So, base = 3 inches , height = 4 inches or base = 4 inches , height = 3 inches.

So, base = 2 inches, height = 6 inches or base = 6 inches , height = 2 inches.
