What is the relationship between roots and factors?

1 answer:

7 0

You can say (x – a) and (x – b) are factors. But the numbers a and b are the roots. The root a is a number that you can substitute in for x and get a true statement. In this case, the first factor is zero.

It's a quadratic equation in disguise. If you let $y=x^{-1}$ , then $y^2=x^{-2}$ , and we can rewrite the equation as

$5y^2-17y+6=0$

Solve for $y$ however you like; we get $y=\dfrac25$ and $y=3$ .

But we want to solve for $x$ , so we have

$y=x^{-1}=\dfrac25\implies x=\dfrac52$

$y=x^{-1}=3\implies x=\dfrac13$

Answer:

The answer is "19 inches and 60 inches".

Step-by-step explanation:

Throughout this question, the choices were missing that's why its correct solution can be defined as follows:

The formula for diameter= $d=2r$

The formula for circumference = $C=2\pi r$

let the r=9.5 so, the diameter and the circumference are:

$\to d= 2 r= 2\times 9.5 =19\\\\\to C= 2 \pi r= 2\times \frac{22}{7} \times 9.5 =59.71 \approx 60 \\\\$

MrRissso [65]

Answer:

48 pounds per square inch

Step-by-step explanation:

d = (1/2)n + 26

d = 50feet

50 = (1/2)n + 26

Subtract 26 from both sides

24 = (1/2)n

Multiply both sides by 2

48 = n
