First notice that the triangle with sides x,y,a and the triangle with sides z,a+b,x are similar. This is true because the angle between sides x,y in the smaller triangle is clearly 30^\circ, while the angle between sides y,z in the larger triangle is clearly 60^\circ. So the triangles are similar with sides x,y,a corresponding to a+b,z,x, respectively.

Now both triangles are 30^\circ-60^\circ-90^\circ, which means there's a convenient ratio between its sides. If the length of the shortest leg is \ell_1, then the length of the longer leg is \ell_2=\sqrt3\ell_1 and the hypotenuse has length \ell_3=\sqrt{{\ell_1}^2+{\ell_2}^2}=2\ell_1.

Since x is the shortest leg in the larger triangle, it follows that a+b=2x, so a+b=15=2x\implies x=\dfrac{15}2

I do not know if is a function or not. Please explain
bezimeni [28]
It is a function because in a function the x's do not repeat. So since there are no two numbers in the x column that are the same, yes it is a function.

What is the compatable number of 358/3
Fudgin [204]
Round 358 to the nearest 5 or 10, which would be 360. 360/3=120 so the compatible number would be 120.

Create a polynomial function in standard form with a leading coefficient of 2 and zeros at 0 1 and 3 brainly
TEA [102]

Answer:

P(x) = 2x^3 - 8x^2 + 6x

Step-by-step explanation:

Given

p =2 -- Leading coefficient

Zeros: 0, 1\ and\ 3

Required

Determine the polynomial

Represent the zeros with a, b and c.

Such that

a = 0

b = 1

c = 3

The polynomial is:

P(x) = p * (x - a) * (x - b) * (x - c)

P(x) = 2 * (x - 0) * (x - 1) * (x - 3)

P(x) = 2x * (x - 1) * (x - 3)

Open bracket

P(x) = (2x^2 - 2x) * (x - 3)

P(x) = 2x^3 - 6x^2 - 2x^2 + 6x

P(x) = 2x^3 - 8x^2 + 6x
