TiliK225 [7]

Answer:

$\large\boxed{10x^2-5x+10\ -\ \bold{quadratic\ trinomial}}$

Step-by-step explanation:

$\text{quadratic trinomial}\ -\ ax^2+bx+c\\\\\text{cubic monomial}\ -\ ax^3\\\\\text{not a polynomial}\ -\ \dfrac{a}{x}\\\\\text{fourth-degree binomial}\ -\ ax^4+bx$

$10x^2-5x+10\\\\\text{the highest power of variable (x) is 2}\to \boxed{x^2}\ \to\ \bold{quadratic}\\\\\text{polynomial has 3 terms}\ \to\ \boxed{10x^2,\ -5x,\ 10}\ \to\ \bold{trinomial}$

The weight W that a horizontal beam can support varies inversely as the length L of the beam. Suppose that an 8 dash m beam can

miss Akunina [59]

<h2>Answer:</h2>

The number of kilograms a 19 m beam can support is:

378.9474 kg

<h2>Step-by-step explanation:</h2>

It is given that:

The weight W that a horizontal beam can support varies inversely as the length L of the beam.

Let k denote the constant.

This means that the weight W and Length L is related as:

$W=\dfrac{k}{L}$

Suppose that an 8 dash m beam can support 900 kg.

This means that L=8 and W=900

Then,

$900=\dfrac{k}{8}\\\\i.e.\\\\k=900\times 8\\\\i.e.\\\\k=7200$

Now , we are asked to find the value of W when L= 19

i.e.

$W=\dfrac{7200}{19}\\\\i.e.\\\\W=378.9474\ kg$
