The first term is x^3 with coefficient 1. Let's call this p = 1
The last term is 36, so we'll call this q = 36

To find all of the possible rational roots or zeros, we divide each factor of q over each factor of p

Factors of p = 1:
-1 and 1

Factors of q = 36: 
-1, 1,
-2, 2
-3, 3
-4, 4
-6, 6
-9,9
-12, 12
-18,18
-36,36

As you can see there's a lot of possible roots. Luckily, p = 1 so that means we simply need to list the factors of q (the plus and minus versions)

The possible rational roots are listed above when I listed all the possible factors of q. Those are the possible x values that make f(x) equal to 0. You need to plug each of those values into f(x) to see which result in 0. It turns out that only x = -4 leads to f(x) = 0 being true. None of the other possible rational roots are actual rational roots.

I need help with this problem,
emmasim [6.3K]

Answer:

  JL = 78

Step-by-step explanation:

The shorter segment is a midline, so is half the length of the longer one.

  2(5x-16) = 4x +34

  5x -16 = 2x +17 . . . . . divide by 2

  3x = 33 . . . . . . . . . . add 16-2x

  x = 11 . . . . . . . . . . divide by 3

Then segment JL is ...

  JL = 4x +34 = 4(11) +34 = 44+34

  JL = 78

A dog is leashed to the corner of a house with a 20 ft long leash. How much running area does the dog have? Round your answer to
11111nata11111 [884]

Answer:

The dog's running area is approximately 942 feet².

Step-by-step explanation:

The dog is leashed to a fixed point, the leash has a length of 20 ft, therefore he can rotate around that point at the maximum distance equal to the length of the leash. This pattern forms a circle, but there is an obstruction, which is the corner of the house. This obstruction takes an arc of the original circle, so the running area of the dog is the area of the whole circle minus the area of the arc formed by the corner of the house.

\text{dog's area} = \text{circle's area} - \text{arc's area}\\\\\text{dog's area} = pi*(20^2) - \frac{90}{360}*pi*(20^2)\\\\\text{dog's area} = \frac{270}{360}*pi*(400)\\\\\text{dog's area} = 942.477\text{ feet}^2

The dog's running area is approximately 942 feet².
