A polynomial P has zeros when x=0, x=-1/6 and x=-3 Whats could be the equation p?

erma4kov [3.2K]

Answer:

P(x) = $x^{3}$ + $\frac{19}{6} x^{2}$ + $\frac{1}{2} x$

Step-by-step explanation:

x(x + 1/6)(x + 3) = P

x( $x^{2}$ + 3x + 1/6(x) + 1/2) = P

x ( $x^{2}$ + 19/6(x) + 1/2) = P

$x^{3}$ + $\frac{19}{6} x^{2}$ + $\frac{1}{2} x$ = P(x)

This trapezium is drawn on a centimetre grid. Find the area of the trapezium.

aivan3 [116]

Answer:

20 unit²

Step-by-step explanation:

A trapezium is given to us on the grid and we need to find out the area of the trapezium . In order to find the area , we need to find the measure of the parallel sides and the distance between the parallel sides.

From the grid :-

$\rm\implies Side_1 = 7 \ units$

$\rm\implies Side_2 = 3 \ units$

$\rm\implies \perp \ Distance =4 \ units$

Now here we got the two parallel sides of the trapezium and the distance between the two parallel sides. Now we can find the area as ,

$\rm\implies Area_{Trapezium}= \dfrac{1}{2}\times ( s_1 + s_2) \times \perp \ Distance \\\\\rm\implies Area = \dfrac{1}{2} \times ( 7 + 3 ) \times 4 \ unit^2 \\\\\rm\implies Area = \dfrac{1}{2} \times ( 10) \times 4 \ unit^2 \\\\\rm\implies\boxed{\rm Area = 20 \ unit^2}$
