1a) Possible rational roots will be of the form
±{divisor of 10}/{divisor of 4}
Divisors of 10 are {1, 2, 5, 10}
Divisors of 4 are {1, 2, 4}

Then possible rational roots are
{±1/4, ±1/2, ±1, ±5/4, ±2, ±5/2, ±5, ±10}

1b) Your answer is correct.

2) One additional root will be the conjuate of the given complex root.
5 -3i

3) If one root is 5 -√7, another will be 5 +√7. Then your polynomial is
P(x) = (x -(5 -√7))*(x -(5 +√7)) = (x -5)^2 -(√7)^2
P(x) = x^2 -10x +18

kotykmax [81]

Answer:

Altogether they sell <u>1634</u> apples.

Step-by-step explanation:

GIven:

Bob, Joe and Larry sold apples at the farmers market.

<u><em>Bob sold 86 apples. </em></u>

<u><em>Joe sold 12 times as many as Bob. </em></u>

<u><em>Larry sold half as many apples as Joe. </em></u>

Now, to find the total apples Bob, Joe and Larry they all sell together.

<u>Number of apples Bob sold</u> = 86.

<u>Number of apples Joe sold</u> = 12 times of 86.

$=12\times 86\\\\=1032.$

<u>Number of apples Larry sold</u> = $\frac{1}{2}\ of\ 1032$

$=\frac{1}{2} \times 1032$

$=516.$

Now, to get the apples they sell altogether we add the number of apples sold by Bob, by Joe and by Larry:

$86+1032+516$

$=1634.$

Therefore, altogether they sell 1634 apples.
