Answer:

  • x² - 8x + 12
  • x³ + 2x² - 15x - 36
  • x³ -2x² - 15x

Step-by-step explanation:

#1) Find the polynomial with roots at 2 and 6

  • (x -2)(x - 6) = x² - 8x + 12

#2) Find the polynomial with a double root at -3 and another root at 4

  • (x+3)(x+3)(x-4) = (x²+6x+9)(x-4) = x³ + 2x² - 15x - 36

#3) Find the polynomial with roots 0, -3 and 5

  • (x -0)(x+3)(x-5) = x(x²-2x - 15) = x³ -2x² - 15x

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

<h3>\frac{a + bc}{wd + f}  = g</h3>

<u>First of all cross multiply</u>

That's

g( wd + f ) = a + bc

<u>Multiply the terms at the left side of the equation</u>

We have

gwd + fg = a + bc

<u>Send fg to the right side of the equation</u>

That's

gwd = a + bc - fg

<u>Divide both sides by dg to make W stand alone</u>

<h3>\frac{gwd}{dg}  =  \frac{a + bc - fg}{dg}</h3>

We have the final answer as

<h2 /><h2>w =  \frac{a + bc - fg}{dg}</h2>

Hope this helps you

never [62]

Answer:

y=(3/5)x+1

Step-by-step explanation:

Slope-intercept form of a line is as follows

y=mx+c, where m is the slope of the line and c is the y intercept.

Hence the equation of the line is y=(3/5)x+1

Ahat [919]

Answer:

x = 11.2

Step-by-step explanation:

hypotenuse = 8.4 (radius) + 5.6 = 14  

using the Pythagorean theorem:

x² = 14² - 8.4² = 196 - 70.56 =125.44

x = √125.44 = 11.2
