Answer:
(2,-2)
Step-by-step explanation:
the x-intercept is 2
and y-intercept is-2
x-intercept is when you have a number comma 0 e.g 3,0. 2,0
y-intercept is when u have 0 comma a number e.g 0,2 0,-5
The answer should be B !! Volume is when you’re determining how much something HOLDS, meaning all parts of it. The rest would be perimeter examples.
Answer:
a) ![P (x) = (x + 3) (x-1) (x-4)](https://tex.z-dn.net/?f=P%20%28x%29%20%3D%20%28x%20%2B%203%29%20%28x-1%29%20%28x-4%29)
b) ![P (x) = (2x + 5) (5x - 4) (x-6)](https://tex.z-dn.net/?f=P%20%28x%29%20%3D%20%282x%20%2B%205%29%20%285x%20-%204%29%20%28x-6%29)
c) ![P (x) = (x-3) (x-1) (x-4) (x + 1) ^ 2](https://tex.z-dn.net/?f=P%20%28x%29%20%3D%20%28x-3%29%20%28x-1%29%20%28x-4%29%20%28x%20%2B%201%29%20%5E%202)
Step-by-step explanation:
<u>For the question a *</u> you need to find a polynomial of degree 3 with zeros in -3, 1 and 4.
This means that the polynomial P(x) must be zero when x = -3, x = 1 and x = 4.
Then write the polynomial in factored form.
![P (x) = (x + 3) (x-1) (x-4)](https://tex.z-dn.net/?f=P%20%28x%29%20%3D%20%28x%20%2B%203%29%20%28x-1%29%20%28x-4%29)
Note that this polynomial has degree 3 and is zero at x = -3, x = 1 and x = 4.
<u>For question b, do the same procedure</u>.
Degree: 3
Zeros: -5/2, 4/5, 6.
The factors are
![x = -\frac{5}{2}\\\\x +\frac{5}{2} = 0\\\\(2x +5) = 0](https://tex.z-dn.net/?f=x%20%3D%20-%5Cfrac%7B5%7D%7B2%7D%5C%5C%5C%5Cx%20%2B%5Cfrac%7B5%7D%7B2%7D%20%3D%200%5C%5C%5C%5C%282x%20%2B5%29%20%3D%200)
---------------------------------------
![x =\frac{4}{5}\\\\x-\frac{4}{5} = 0\\\\(5x-4) = 0](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B4%7D%7B5%7D%5C%5C%5C%5Cx-%5Cfrac%7B4%7D%7B5%7D%20%3D%200%5C%5C%5C%5C%285x-4%29%20%3D%200)
--------------------------------------
![x = 6\\\\(x-6) = 0](https://tex.z-dn.net/?f=x%20%3D%206%5C%5C%5C%5C%28x-6%29%20%3D%200)
--------------------------------------
![P (x) = (2x + 5) (5x - 4) (x-6)](https://tex.z-dn.net/?f=P%20%28x%29%20%3D%20%282x%20%2B%205%29%20%285x%20-%204%29%20%28x-6%29)
<u>Finally for the question c we have</u>
Degree: 5
Zeros: -3, 1, 4, -1
Multiplicity 2 in -1
![x = -3\\\\(x-3) = 0](https://tex.z-dn.net/?f=x%20%3D%20-3%5C%5C%5C%5C%28x-3%29%20%3D%200)
--------------------------------------
![x = 1\\\\(x-1) = 0](https://tex.z-dn.net/?f=x%20%3D%201%5C%5C%5C%5C%28x-1%29%20%3D%200)
--------------------------------------
![x = 4\\\\(x-4) = 0](https://tex.z-dn.net/?f=x%20%3D%204%5C%5C%5C%5C%28x-4%29%20%3D%200)
----------------------------------------
![x = -1\\\\(x + 1) = 0](https://tex.z-dn.net/?f=x%20%3D%20-1%5C%5C%5C%5C%28x%20%2B%201%29%20%3D%200)
-----------------------------------------
![P (x) = (x-3) (x-1) (x-4) (x + 1) ^ 2](https://tex.z-dn.net/?f=P%20%28x%29%20%3D%20%28x-3%29%20%28x-1%29%20%28x-4%29%20%28x%20%2B%201%29%20%5E%202)
The answer is 82. hope this helps!
Answer:
the answer is c because if you look at the number line it is divided into 3 equal parts and b and c is before -1 but b is -2/3 and c is -1/3 so the answer is c
