Answer:
-3, 0, 5
Step-by-step explanation:
You want the zeros of P(x) = x³ − 2x² − 15x using the factored form.
<h3>Factored form</h3>
We notice right away that x is a factor of every term. Factoring that out gives us a quadratic to factor:
P(x) = x(x² -2x -15)
To factor this, we need two factors of -15 that have a sum of -2. The factors -5 and +3 have those properties. That means our factored form is ...
P(x) = x(x +3)(x -5) . . . . factored form
<h3>Zeros</h3>
This product will be zero when any of its factors is zero. Considering them one at a time, we find the zeros of P(x) to be ...
x = 0
x +3 = 0 ⇒ x = -3
x -5 = 0 ⇒ x = 5
The zeros of P(x) are -3, 0, 5.
Answer:
Abou 544.64 or exactly 544.637684
Step-by-step explanation:
You need to remeber to add the new interest every quarter. To find how much the new interest increases each quarter.
Yes! you should watch morbius.
is a closed surface with interior , so you can use the divergence theorem.
By the divergence theorem, the flux of across is given by the integral of over :
Convert to cylindrical coordinates, setting
The integral is then
