Fill in the missing portions of the function to rewrite g(x) = 3a^2 − 42a + 135 to reveal the zeros of the function. What are th
mariarad [96]

Answer:

g(x) = 3(x-9)(x-5)

Zeros: x = 9 and x = 5.

Step-by-step explanation:

Given a second order polynomial expressed by the following equation:

ax^{2} + bx + c, a\neq0.

This polynomial has roots x_{1}, x_{2} such that ax^{2} + bx + c = a(x - x_{1})*(x - x_{2}), given by the following formulas:

x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}

x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}

\bigtriangleup = b^{2} - 4ac

In this question:

g(x) = 3x^{2} - 42a + 135

So

a = 3, b = -42, c = 135

\bigtriangleup = (-42)^{2} - 4*3*135 = 144

x_{1} = \frac{-(-42) + \sqrt{144}}{2*3} = 9

x_{2} = \frac{-(42) - \sqrt{144}}{2*3} = 5

So

g(x) = 3(x-9)(x-5)

Zeros: x = 9 and x = 5.

The angled of a triangle are in the ratio of 2:3:4 find angles in degrees
jeyben [28]

40°, 60° and 80°

sum the parts of the ratio 2 + 3 + 4 = 9

The sum of the angles in a triangle = 180°

Divide 180 by 9 to find one part of the ratio

\frac{180}{9} = 20° ← 1 part of the ratio

2 parts = 2 × 20 = 40°

3 parts = 3 × 20 = 60°

4 parts = 4 × 20 = 80°

The angles in the triangle are 40°, 60° and 80°
